Most academic fields are blessed with public intellectuals—people who contribute big ideas to their disciplines and also to public discourse. Economics has had (among others) Paul Krugman and Milton Friedman. History has had Henry Louis Gates, Jr. and Doris Kearns Goodwin. Evolutionary biology has had Richard Dawkins and E. O. Wilson. And psychological science? On my top 10 psychology public intellectuals list—admittedly reflecting my current interests—would be the late Daniel Kahneman, along with Martin Seligman, Elizabeth Loftus, Steven Pinker, Jennifer Eberhardt, Angela Duckworth, Roy Baumeister, Jean Twenge, and Robert Cialdini. With so many deserving candidates, your interests and list will differ. Likely it would now also include Jonathan Haidt, whose new book, The Anxious Generation, appeared with a trifecta—as the simultaneous #1 nonfiction bestseller at the New York Times, Publisher’s Weekly, and Amazon—and with featured reviews in major newspapers and The New Yorker; interviews on TV networks, talk shows, and podcasts; and Haidt’s own The Atlantic feature article. In collaboration with Jean Twenge (my social psychology text coauthor), Haidt aims less to sell books than to ignite a social movement. Teen depression, anxiety, and suicidal thinking have soared in the smartphone/social media era, Haidt and Twenge observe, and especially so for those teen girls who devote multiple daily hours to social media. For an excellent 7-minute synopsis of their evidence—perfect for class discussion, youth groups, or the family dinner table—see here. Their solution is straightforward: We need to stop overprotecting kids from real-world challenges and under-protecting them in the virtual world. We should decrease life experience–blocking phone-based childhood and increase resilience-building unrestricted play and in-person social engagement. To make this practical, Haidt offers schools and parents four recommendations: No smartphones until high school (flip phones before). No social media before age 16. Phone-free schools (deposit phones on arrival). More free play and unsupervised real-world responsibility.  Given such high visibility assertions, Haidt and Twenge’s writings are understandably stimulating constructive, open debate that models what Haidt advocated in his earlier The Coddling of the American Mind (2018), and in founding the Heterodox Academy to support “open inquiry, viewpoint diversity, and constructive disagreement.” His colleague critics, including psychologist Candice Odgers writing in Nature and an Oxford research team, question the smartphone effect size and offer alternative explanations for the teen mental health crisis. Although the research story is still being written, my reading of the accumulated evidence supports Haidt and Twenge, whose replies to their skeptics provide a case study in rhetorical argumentation: Are they merely offering correlational evidence? No, longitudinal studies and experiments confirm the social media effect, as do quasi-experiments that find mental health impacts when and where social media get introduced. Are the effects too weak to explain the huge increase in teen girls’ depression and anxiety? No, five social media hours a day double teen girls’ depression risk. Moreover, social media have collective effects; they infuse kids’ social networks. Is teen malaise instead a product of family poverty and financial recession? No, it afflicts the affluent as well, and has increased during an era of economic growth. Are the problems related to U.S. politics, culture, or school shootings? No, they cross Western countries. Are teens more stressed due to increased school pressures and homework? No; to the contrary, homework pressure has declined. Two other alternative explanations—that kids are experiencing less independence and less religious engagement—actually dovetail with the social media time-drain evidence. (Haidt, a self-described atheist, includes a chapter on the smartphone-era decline in experiences of spiritual awe, meditation, and community.) Haidt’s inspiring an international conversation about teens and technology takes my mind back to 2001. A committee of four of us, led by Martin Seligman, evaluated candidates for the first round of Templeton Foundation–funded positive psychology prizes. Our $100,000 top prize winner—recognizing both achievements and promise—was an impressive young scholar named (you guessed it) Jon Haidt. More than we expected, we got that one right. In 2024, our culture is becoming wiser and hopefully healthier, thanks to Haidt’s evidence-based teen mental health advocacy, enabled by his persistent public voice.

Despite their differences, most of today’s U.S. Republicans and Democrats have one thing in common: They despise those in the other party, with many expressing physical disgust for their political opposites, whom they also regard as plainly stupid. In a recent Pew survey, partisans regarded one another as closed-minded, dishonest, and immoral. Nearly half would be upset if their child married someone from the other party, which fewer today—less than 4 percent—are doing. (Interracial marriages are now much more common than inter-political marriages.) Moreover, with young women increasingly identifying as “liberal”—today’s growing gender divide forms a barrier to heterosexuals looking for a kindred spirit to marry. Amid today’s mutual loathing—affective polarization, political scientists call it—two centrist social psychologist teams remind us that both sides have their virtues. In 2012, Jonathan Haidt, in The Righteous Mind: Why Good People Are Divided by Politics and Religion, argued that the right and left have complementary insights: Conservatives and liberals are both rooted in respectable moral values—with conservatives prioritizing loyalty, authority, and sanctity, and liberals prioritizing care for others and fairness. So before disparaging your political opposites, Haidt advises, consider their moral foundations. Now, in 2023, Roy Baumeister and Brad Bushman concur that there is wisdom on both the left and the right: “Both left and right have valid insights and helpful policies.” Societies evolved to perform two crucial tasks, note Baumeister and Bushman: amass resources, and distribute them. Political conservatives, such as U.S. Republicans—draw their support primarily from those who produce resources: farmers and ranchers, businesspeople and merchants, bankers and contractors, real estate developers and fossil fuel producers. Political progressives, such as U.S. Democrats, care more about redistributing resources, and draw their support from government workers, educators, entertainers, and lower income people who have most to gain from egalitarian income sharing. For cultures to grow and their people to flourish, both resource accumulation and shared distribution are essential, Baumeister and Bushman argue. Thus, over time, flourishing democracies—including nearly all countries that the UN ranks at the high end of life quantity and quality—have valued both aims, and their governments have tended to alternate between center-right and center-left. Even so, this leaves practical issues for debate, they add: If incentives (via profits for innovation) increase resources, but also increase inequality, then where is the optimum point for redistribution (without depleting the motivation to produce)? Should incentives for resource production include the right to pass hard-earned fortunes down to privileged children and grandchildren who played no part in creating them? What structural changes might alleviate today’s partisan extremism? In gerrymandered congressional districts, for example, the primary election becomes the main hurdle to office—which leads to more extreme candidates who need offer no appeal to the other party. In my state, Michigan, a citizen-initiated ballot proposal ended gerrymandering by defining state and congressional districts that “shall not provide disproportionate advantage to political parties or candidates.” Other states and cities have embraced ranked-choice voting, which rewards candidates (often moderates) who appeal to a broad range of voters. Other social psychologists critique their colleagues who see equivalent wisdom in both right and left, or who report that “bias is bipartisan.” It’s a false equivalence, notes John Jost, to assume that U.S. Republicans and Democrats equally convey misinformation, conspiracy thinking, intolerance, political violence, and dogmatism. Even so, grant this much, say Baumeister and Bushman: Humankind has succeeded thanks to the evolution of human cultures, which have done “two things effectively: (1) amassing resources, and (2) sharing resources through the group. Back in the evolutionary past, most adults took part in both tasks but the two tasks have grown apart, and in the modern world they pull against each other. Nevertheless, both tasks are important, indeed essential, for a flourishing society.” As a political partisan myself, Baumeister and Bushman bid me to remember: There can be wisdom across the political divide.

By now you’ve likely heard: Teen sadness, depression, and suicide attempts have soared since 2010, especially among girls. From 2011 to 2020, suicide-related issues rose fourfold, from 0.9 percent of U.S. pediatric emergency room visits to 4.2 percent. The teen mental health decline is unprecedented. And it is substantial. Although debate over causation continues, varied studies converge in pointing to social media as a likely major culprit. And legislators have taken note, by proposing bipartisan state and congressional bills that would limit teen social media access. The CDC’s new 100-page “Youth Risk Behavior Surveillance (YRBS) samples 17,232 ninth to twelfth graders from all U.S. public and private schools, and documents the malaise of today’s teen girls. But another troubled, less-discussed group also caught my eye—what the report refers to as LGBQ+ teens (transgender teens were not separately surveyed). A CDC summary document portrays the significant mental health challenges of LGBQ+ high schoolers: Poor mental health in last 30 days: Persistent feelings of sadness or hopelessness: Seriously considered attempting suicide: Made a suicide plan in the last year: Attempted suicide: These data replicate findings in other reports. In 2022, the Trevor Project, which studies and supports the mental health of LGBTQ youth, collected more than 34,000 reports from 13- to 24-year-old LGBTQ youth and young adults. Although the respondents were self-selected, the online survey found, exactly as did the CDC, that “45% of LGBTQ youth seriously considered attempting suicide in the past year.” What explains the sexual identity–mental health correlation? The common presumption is that the stigma and stress faced by sexual minorities exacts a toll. “We must recognize that LGBTQ young people face stressors simply for being who they are that their peers never have to worry about,” observed Trevor Project CEO Amit Paley. Digging deeper into the CDC’s YRBS data, it appears that, indeed, even with the growing acceptance of people who are gay, the stigmatization and stressors remain. Kids—and society at large—can be cruel. More findings: Did not go to school because of safety concerns: Bullied online: Bullied at school: These data prompt our sobering reflection on the struggles of LGBTQ youth. They also make us wonder: Might sexual-minority youth be less vulnerable to depression, hopelessness, and suicidal thinking if given . . . more access to mental health services? . . . a support group in a safe space? . . . greater public education about the realities of sexual orientation? Or what would you suggest?

You’ll be told that your hearing’s so murky and muddy, your case calls for special intensified study. They'll test you with noises from far and from near and you'll get a black mark for the ones you can’t hear. Then they’ll say, “My dear fellow, you’re deafer than most. But there’s hope, since you’re not quite as deaf as a post.” ~Dr. Seuss in You’re Only Old Once! Dr. Seuss could be talking to me. Although not part of the signing Deaf culture, I am—without my cochlear implant in one ear and hearing aid in the other—deaf. With the technology removed, I experience the sound of near silence. I cannot hear my wife from the adjacent pillow unless I put my “good” ear 4 inches from her mouth. Not quite as deaf as a post! My loss, which began as an unusual low frequency loss that made me a case of special intensified study, is the least of my mother’s gifts, which she inherited from her mother. Our shared experience is the result of a single gene defect, which a University of Iowa hearing geneticist identified for me during our years together on the advisory committee of NIH’s National Institute of Deafness and Other Communication Disorders: “You have DFNA6/14 hearing loss caused by a mutation in WFS1.” Yet I am really not so special, for there are some 38 million American, and 4 million Canadian, adults who experience some “trouble hearing,” or who have at least a 25 decibel loss in both ears. Hearing loss is one of the great invisible disabilities. In my workplace, I have many times experienced unintended exclusion—mostly unnoticed by others. In department meetings, I have missed much of others’ input. Attending lectures, I have sat trapped in the middle of an audience, missing most of the spoken word. Hearing worsens in auditoriums with distant ceiling speakers and in uncarpeted hard-surfaced rooms with reverberating sound. Facilities designers, take note! Had I been left out in such settings because of wheelchair inaccessibility, people would be aghast, and would engineer a remedy. Hearing loss, by contrast, is unseen and thus often unremedied. Moreover, Covid-era masking made things worse, both muffling sound and precluding natural lip reading. With thanks to cartoonist Dave Coverly (www.speedbump.com). Hearing loss does nevertheless have a few compensations. Normal-hearing folks have eyelids but no earlids. I have both. When working in a noisy coffee shop, I can turn down the sound distractions. Has your sleep been disturbed by hotel hallway noise? That’s no problem for people like me. Earlier this week, my wife’s sleep was disturbed by our bedroom’s phone ringing at 1:30 a.m. I was blissfully unaware. When hearing folks witness those with hearing loss not comprehending speech, they may misattribute the problem. During his Congressional testimony regarding possible Russian election interference, former special counsel Robert Mueller on 48 occasions asked to have questions repeated. Commentators, not appreciating that he is hearing-challenged, observed that he seemed “confused,” “uncertain,” and “forgetful.” And it was all so easily avoidable in one of three ways—each of which I have experienced as a godsend: A loudspeaker nearer his ears could have given him vastly clearer sound. Real-time captioning on a table screen, like the TV captioning we use at home, could have made the spoken words instantly clear. A hearing loop surrounding the room could have magnetically transmitted the voice from each microphone directly to the inexpensive telecoil sensor that comes with most modern hearing aids and cochlear implants. (See here, here, and here for more on hearing loops, which are now in thousands of auditoriums, worship places, and airports. Full disclosure: The first site is my own informational website, and the last describes our collective advocacy to bring this technology to all of the United States.) There are other ways to support people with hearing loss: Create quieter working and eating places, with materials that absorb reverberant sound. When beginning a talk, do not ask “Can everybody hear me?” and then put down the mic. (That question can elicit but one answer.) When offered a mic, use it, held close to the mouth: 4. When hosting a group meeting, cluster seating close together (to minimize speaker-to-listener distance). 5. Enable presenters to see their PowerPoint presentation in front of them, such as with a podium laptop--to minimize their turning their back to the audience when talking through their slides. Those of us with hearing loss can also act to give ourselves ear-opening experiences: We can be “out of the closet”: “I have hearing loss, so it would help me if we could be seated in a quiet corner [or] if we could turn the music down.” When attending talks, we can sit front and center. We can equip our ears with today’s “superfecta” digital hearing aids, offering both a Bluetooth link from smartphone to hearing aids and a telecoil for hearing loop reception. (Studies indicate that those with hearing loss who resist hearing aids—often because they are unaware of what they’re missing—are at increased risk for social isolation, depression, and eventual dementia.) We can harness other hearing technologies. For example, I love my hand-held directional remote mic, such as available here. When pointed at someone in a meeting or at a noisy reception, it zooms in on their voice. When connected to my laptop, my hearing aids become in-the-ear speakers. Hear ye! Hear ye! The happy news is that today’s technologies enable people like me to escape the deafness that caused Beethoven to lament living “like an exile” and to experience social encounters with “a hot terror.” I am also spared the isolation that plagued my deaf mother’s later years. No longer must our hearing be “so murky and muddy.” Hearing is not the only vehicle for communication. ASL is also a genuine language. But for those of us who have experienced hearing, how good it is. For we are, as Aristotle discerned, “the social animal.” We need to belong. We live in relationships with others—a feature of our human nature immediately recognized in the Old Testament creation story (“It is not good that the man should be alone”). As people who need people, we can therefore celebrate the wonder of hearing—of mind-to-mind communication via vibrating air molecules.

Artificial intelligence—the long-promised computer simulation of human intelligence—has arrived. A striking new example: On December 1st, OpenAI released a chatbot, ChatGPT, that you can play with here. I was introduced to this by one of my children, a computer systems engineer, who is mightily impressed (and not normally so wow’d by new technology that impresses me). He illustrated with a couple examples of his own: In this next example, the Sherlock joke, though wonderful, is familiar. But consider ChatGPT’s answer to the follow-up question: Impressive! Then I challenged Chat GPT to write some psychological science. I asked it to write me an essay explaining the difference between classical and operant conditioning. Its response would have merited an A grade from any instructor. Then I reset the conversation and asked it the same question again, and it responded with a new and equally impressive essay. Then I gave it a harder challenge (seeing if it understands a concept that a respected public intellectual and his editor miscast): Kudos to ChatGPT, which grasps that oft-misunderstood psychological concept. I also wondered if students could ask ChatGPT to improve their writing before handing in a paper: The future is here. For ideas on how you can explore and play with ChatGPT, or with OpenAI Playground, Ethan Mollick offers a variety of possibilities here. For crisp synopses of AI's history and future, see here. Or see here how Michelle Huang “trained an ai chatbot on my childhood journal entries" so that she could "engage in real-time dialogue with my 'inner child.'" And then consider: How might the new AI enable creative thinking? Tutoring? Cheating? Paper or essay grading? Conversing about important topics?  (For David Myers’ other essays on psychological science and everyday life, visit TalkPsych.com or his new essay collection, How Do We Know Ourselves: Curiosities and Marvels of the Human Mind.

Reading my discipline’s discoveries leaves me sometimes surprised and frequently fascinated by our mind and its actions. In hopes of sharing those fascinations with the wider world, I’ve authored How Do We Know Ourselves? Curiosities and Marvels of the Human Mind, which I’m pleased to announce is published today by Farrar, Straus and Giroux. Its 40 bite-sized essays shine the light of psychological science on our everyday lives. I take the liberty of sharing this with you, dear readers of this wee blog, partly because the book is also a fund-raiser for the teaching of high school psychology. (All author royalties are pledged to support psychology teaching—half to the American Psychological Foundation to support Teachers of Psychology in Secondary Schools, and half to the Association for Psychological Science Fund for the Teaching and Public Understanding of Psychological Science.) My hope is that some of you—or perhaps some of your students (a Christmas gift idea for their parents?)—might enjoy these brief and playful musings half as much as I enjoyed creating them.

“The best time to plant a tree was 20 years ago. The second-best time is now.” ~ Anonymous proverb Character education’s greatest task is instilling a mark of maturity: the willingness to delay gratification. In many studies, those who learn to restrain their impulses—by electing larger-later rather than smaller-now rewards—have gone on to become more socially responsible, academically successful, and vocationally productive. The ability to delay gratification, to live with one eye on the future, also helps protect people from the ravages of gambling, delinquency, and substance abuse. In one of psychology’s famous experiments, Walter Mischel gave 4-year-olds a choice between one marshmallow now, or two marshmallows a few minutes later. Those who chose two later marshmallows went on to have higher college graduation rates and incomes, and fewer addiction problems. Although a recent replication found a more modest effect, the bottom line remains: Life successes grow from the ability to resist small pleasures now in favor of greater pleasures later. Marshmallows—and much more—come to those who wait. The marshmallow choice parallels a much bigger societal choice: Should we prioritize today, with policies that keep energy prices and taxes low? Or should we prioritize the future, by investing now to spare us and our descendants the costs of climate change destruction? “Inflation is absolutely killing many, many people,” said U.S. Senator Joe Manchin, in explaining his wariness of raising taxes to fund climate mitigation. Manchin spoke for 50 fellow senators in prioritizing the present. When asked to pay more now to incentivize electric vehicles and fund clean energy, their answer, on behalf of many of their constituents, is no. But might the cost of inaction be greater? The White House Office of Management and Budget projects an eventual $2 trillion annual federal budget cost of unchecked climate change. If, as predicted, climate warming increases extreme weather disasters, if tax revenues shrink with the economy’s anticipated contraction, and if infrastructure and ecosystem costs soar, then are we being penny-wise and pound-foolish? With the worst yet to come, weather and climate disasters have already cost the U.S. a trillion dollars over the past decade, with the total rising year by year. nattrass /E+/Getty Images The insurance giant Swiss Re also foresees a $23 trillion global economy cost by 2050 if governments do not act now. The Big 4 accounting firm Deloitte is even more apprehensive, projecting a $178 trillion global cost by 2070. What do you think: Are our politicians—by seizing today’s single economic marshmallow—displaying a mark of immaturity: the inability to delay gratification for tomorrow’s greater good? A related phenomenon, temporal discounting, also steers their political judgments. Even mature adults tend to discount the future by valuing today’s rewards—by preferring, say, a dollar today over $1.10 in a month. Financial advisors therefore plead with their clients to do what people are not disposed to do . . . to think long-term—to capitalize on the power of compounding by investing in their future. Alas, most of us—and our governments—are financially nearsighted. We prioritize present circumstances over our, and our children’s, future. And so we defend our current lifestyle by opposing increased gas taxes and clean-energy mandates. The western U.S. may be drying up, sea water creeping into Miami streets, and glaciers and polar ice retreating, but even so, only “1 percent of voters in a recent New York Times/Siena College poll named climate change as the most important issue facing the country, far behind worries about inflation and the economy.” The best time to plant a tree, or to have invested in climate protection, was 20 years ago. The worst time is 20 years from now, when severe climate destruction will be staring us in the eye. As we weigh our present against our future, psychological science reminds our political representatives, and all of us, of a profoundly important lesson: Immediate gratification makes today easy, but tomorrow hard. Delayed gratification makes today harder, but tomorrow easier. (For David Myers’ other essays on psychological science and everyday life, visit TalkPsych.com.

With 45,000+ annual U.S. firearm deaths (123 per day, from homicide, suicide, and accidents), America has a gun problem, of which the recent Buffalo, Uvalde, and Highland Park mass killings are horrific examples. In response, we often hear that the problem is not America’s 400 million guns but its people. “We have a serious problem involving families, involving drugs, involving mental health in this country,” asserted Colorado congressional representative Ken Buck. “We have become a less safe society generally. Blaming the gun for what’s happening in America is small-minded.” To protect against mass killings by 18-year-olds, as in Buffalo and Uvalde, we are told that we don’t need to match the minimum age for assault rifle purchase, still 18 after the new gun safety act, with the age for beer purchase, 21. We don’t need to train and license gun owners as we do drivers. We don’t need safe-storage laws or restrictions on large-capacity magazines. Instead, we need to fix the problem perceived by Texas Governor Greg Abbott and National Rifle Association chief executive Wayne LaPierre: evil people. To solve the gun violence problem, we need better people, enabled by commendable social changes: more married fathers, less pornography, fewer violent video games. And most importantly, we’re told, we need to deal with mass killers’ mental sickness. “People with mental illness are getting guns and committing these mass shootings,” observed former U.S. Speaker of the House Paul Ryan. While president, Donald Trump agreed: “When you have some person like this, you can bring them into a mental institution.” Mass killers, he later added, are “mentally ill monsters.” However, reality intrudes. As I documented in an earlier essay, most mentally ill people are nonviolent, most violent criminals and mass shooters have not been diagnosed as mentally ill, and rare events such as mass shootings are almost impossible to predict. As much as we psychologists might appreciate the ostensible high regard, today’s psychological science lacks the presumed powers of discernment. If mental-health assessments cannot predict individual would-be killers, three other factors (in addition to short-term anger and alcohol effects) do offer some predictive power: Demographics. As the recent massacres illustrate, most violent acts are committed by young males. The late psychologist David Lykken made the point memorably: “We could avoid two-thirds of all crime simply by putting all able-bodied young men in cryogenic sleep from the age of 12 through 28.” Past behavior. It’s one of psychology’s maxims: The best predictor of future behavior is past behavior. The best predictor of future GPA is past GPA. The best predictor of future employee success is past employee success. The best predictor of future class attendance or smoking or exercise is, yes, the recent past. Likewise, recent violent acts are a predictor of violent acts. Guns. Compared to Canada, the United States has 3.5 times the number of guns per person and 8.2 times the gun homicide rate. Compared to England, the U.S. has 26 times as many guns per person—and 103 times the gun homicide rate. To check U.S. state variations, I plotted each state’s gun-in-home rate with its gun homicide rate. As you can see, the correlation is strongly positive, ranging from (in the lower left) Massachusetts, where 15 percent of homes have a gun, to Alaska, where 65 percent of homes have a gun—and where the homicide rate is 7 times greater. Of these three predictor variables, gun policy is one that, without constraining hunters’ rights, society can manage with some success: When nations restrict gun access, the result has been fewer guns in civilian hands, which enables fewer impulsive gun uses and fewer planned mass shootings. Many people nevertheless believe that, as Senator Ted Cruz surmised after the Uvalde shooting, “What stops arms bad guys is armed good guys.” Never mind that in one analysis of 433 active shooter attacks on multiple people—armed lay citizens took out active shooters in only 12 instances. Many more—a fourth of such attacks—ended in a shooter suicide. Moreover, if the answer to bad guys with guns is to equip more good guys with guns, then why are states with more armed good guys more homicidal? What explains the state-by-state guns/homicide correlation? Are the more murderous Alaskans (and Alabamians and Louisianans) really more “evil” or “mentally ill”? Or is human nature essentially the same across the states, with the pertinent difference being the weapons?

“Donald Trump . . . unleashed something, that is so much bigger than he is now or ever will be: He pushed the limits of acceptability, hostility, aggression and legality beyond where other politicians dared push them.” ~ Charles Blow, 2022 This is a venomous time. From 2015 to 2019, FBI-reported U.S. hate crimes increased 25 percent. Social psychologists have therefore wondered: Is this increase, and the accompanying resurgence of white nationalism, fed by Donald Trump’s rhetoric—his saying, for example, that the torch-carrying Charlottesville white nationalists included some “very fine people”? Or did the president’s tweets and speeches merely reflect existing prejudices, which, in a few disturbed individuals, fed hateful acts? Simply put: Do political leaders’ words merely voice common prejudices and grievances? Or do they also amplify them? They do both. Leaders play to their audiences. And when prominent leaders voice prejudices, it then becomes more socially acceptable for their followers to do likewise. When disdain for those of another race or religion or sexual orientation becomes socially acceptable, insults or violence may ensue. Social norms mutate, and norms matter. A new Nature Human Behaviour report of 13 studies of 10,000+ people documents the norm-changing influence of President Trump’s rhetoric. During his presidency, “Explicit racial and religious prejudice significantly increased amongst Trump’s supporters,” say the report’s authors, social psychologists Benjamin Ruisch (University of Kent) and Melissa Ferguson (Yale University). Some of their studies followed samples of Americans from 2014 to 2017, ascertaining their attitudes toward Muslims (whether they agreed, for example, that “Islam is quite primitive”). As seen on this 7-point scale of anti-Muslim prejudice, Trump supporters’ anti-Muslim sentiments significantly increased. But what about those for whom Donald Trump was not a positive role model? Would they become less imitative? Might they be like those observed in one study of jaywalking, in which pedestrians became less likely to jaywalk after observing someone they didn’t admire (a seeming low-status person) doing so? Indeed, Trump opponents exhibited decreased Muslim prejudice over time. Moreover, Ruisch and Ferguson found, “Trump support remained a robust predictor of increases in [anti-Muslim] prejudice” even after controlling for 39 other variables, such as income, age, gender, and education. Trump support also predicted increases in other forms of prejudice, such as racial animus (“Generally, Blacks are not as smart as Whites are”) and anti-immigrant attitudes. Pew national surveys similarly find that the attitude gap between those voting for and against Trump widened from 2016 to 2020 (see the 2020 data below). The 57 percent of Democrat voters who, in 2016, agreed that it’s more difficult to be a Black American than a White American increased to 74 percent in 2020, illustrating the general historical trend toward more egalitarian attitudes. But no such positive shift occurred among Trump supporters, whose agreement with the concept of Black disadvantage actually declined slightly, from 11 percent in 2016 to 9 percent in 2020. Ruisch and Ferguson see shifting social norms at work. “Trump supporters perceive that it has become more acceptable to express prejudice since Trump’s election . . . and the perception that prejudice is more acceptable predicts greater personal prejudice among Trump supporters.” Their conclusion aligns with the earlier finding of a political science research team—“that counties that had hosted a 2016 Trump campaign rally saw a 226 percent increase in reported hate crimes over comparable counties that did not host such a rally.” The happier news is that political leaders’ speech can work for better as well as for worse. In one month during 2021, a Stanford research team randomly assigned 1014 counties with low vaccination rates to receive 27-second YouTube ads (via TV, website, or app). Each featured Donald Trump’s expressed support for Covid vaccinations. After a Fox News anchor’s introduction, shown below, clips featured the Trumps getting the vaccine, with Ivanka saying, “Today I got the shot. I hope you do too” and Donald explaining “I would recommend it, and I would recommend it to a lot of people that don’t want to get it.” At a cost of about $100,000, the add was viewed 11.6 million times by 6 million people. When compared with 1018 control counties, the experimental treatment counties experienced an additional 104,036 vaccinations, for an additional cost of less than $1 each. The simple lesson: Under the influence of powerful leaders, social norms and behaviors can change. And social norms matter—sometimes for worse, but sometimes for better.

If you live in one of 30 U.S. states with recently legalized sports betting, you’ve surely noticed: Your online media and television have been awash with sports betting ads from DraftKings, FanDuel, Caesars Sportsbook, and more. For this, we can thank the 2018 U.S. Supreme Court’s overturning of the sports betting ban, which also led the NFL in 2021 to allow sports betting ads even during its broadcasts and live-streams. With the deluge of ads, which sometimes offer new customers free money to lure initial bets, the gaming industry hopes to hook new betters and expand its customer base from the current 50 million or so Americans who gamble on sports. For most, the few dollars wagered may be nothing more than a bit of exciting fun. But for some—those who develop a gambling disorder—the betting becomes compulsive and debilitating, as gamblers crave the excitement, seek to redeem their losses, and lie to hide their behavior. Family finances suffer. Bankruptcies happen. Divorces result. And with the sports betting floodgates now opened, problem gambling is increasing. “The National Problem Gambling helpline is receiving an average of more than 22,500 calls a month this year,” reports the Wall Street Journal, “up from a monthly average of about 14,800 last year.” Pgiam/E+/Getty Images It’s no secret that, over time, the house wins and gamblers nearly always lose. So how does the gambling industry manage to suck nearly a quarter-trillion dollars annually from U.S. pockets? Are state lotteries, like Britain’s National Lottery, merely (as one of my sons mused) “a tax on the statistically ignorant”? (My state’s lottery pays out as winnings only 61 cents of each dollar bet.) To remind folks of the power of psychological dynamics, and to prepare them to think critically about the allure of gambling inducements, we can ask: What psychological principles does the gambling industry exploit? Consider these: Partially (intermittently) reinforced behavior becomes resistant to extinction. Pigeons that have been reinforced unpredictably—on a “variable ratio” schedule—may continue pecking thousands more times without further reward. Like fly fishing, slot machines and sports gambling reward people occasionally and unpredictably. So hope springs eternal. The judgment-altering power of the availability heuristic. As Nobel laureate psychologist Daniel Kahneman has shown, people tend to estimate the commonality of various events based on their mental availability—how readily instances come to mind. Casinos have the idea. They broadcast infrequent wins with flashing lights, while keeping the far more common losses invisible. Likewise, gamblers, like stock day-traders, may live to remember and tell of their memorable wins, while forgetting their more mundane losses. Illusory correlations feed an illusion of control. People too readily believe that they can predict or control chance events. When choosing their own lottery number (rather than being assigned one), people demand much more money when invited to sell their ticket. If assigned to throw the dice or spin the wheel themselves, their confidence increases. Dice players also tend to throw hard if wanting high numbers, and soft for low numbers. When winning, they attribute outcomes to their skill, while losses become “near misses.” Losing sports gamblers may rationalize that their bet was actually right, except for a referee’s bad call or a freakish ball bounce. Difficulty delaying gratification. Those who from childhood onward have learned to delay gratification—who choose two marshmallows later over one now (as in the famous “marshmallow test” experiment)—become more academically successful and ultimately productive. They are also less likely to smoke, to commit delinquent acts, and to gamble—each of which offer immediate reward, even if at the cost of diminished long-term health and well-being. The gaming industry seeks present-minded rather than future-minded folks. They aim to hook those who will elect that figurative single marshmallow satisfaction of today’s desire over the likelihood of a greater deferred reward. Credible, attractive communicators exploit “peripheral route persuasion.” Endorsements by beautiful, famous, or trusted people can add to the allure. As former gaming industry marketing executive Jack O’Donnell notes, the sports gambling industry harnesses sports celebrity power when paying former all-star receiver Jerry Rice to dump Gatorade on a winning DraftKings bettor, when trusted sportscaster Brent Musburger encourages placing a bet, and when legendary quarterback and former Super Bowl MVP Drew Brees admonishes people to live your “Bet Life.” Each of these psychological dynamics has its own power. When combined, they help us understand the gaming industry’s lure, and, for some, its tragic addictive force.

“Listen, we all hoped and prayed the vaccines would be 100 percent effective, 100 percent safe, but they’re not. We now know that fully vaccinated individuals can catch Covid, they can transmit Covid. So what’s the point?” ~U.S. Senator Ron Johnson, Fox News, December 27, 2021 “I have made a ceaseless effort not to ridicule, not to bewail, not to scorn human actions, but to understand them.” ~Baruch Spinoza, Political Treatise, 1677 Many are aghast at the irony: Unvaccinated, unmasked Americans remain much less afraid of the Covid virus than are their vaccinated, masked friends and family. This, despite two compelling and well-publicized facts: Covid has been massively destructive. With 5.4 million confirmed Covid deaths worldwide (and some 19 million excess Covid-era deaths), Covid is a great enemy. In the U.S., the 840,000 confirmed deaths considerably exceed those from all of its horrific 20th-century wars. The Covid vaccines are safe and dramatically effective. The experience of 4.5+ billion people worldwide who have received a Covid vaccine assures us that they entail no significant risks of sickness, infertility, or miscarriage. Moreover, as the CDC illustrates, fully vaccinated and boosted Americans this past fall had a 10 times lower risk of testing positive for Covid and a 20 times lower risk of dying from it. Given Covid’s virulence, why wouldn’t any reasonable person welcome the vaccine and other non-constraining health-protective measures? How can a U.S. senator scorn protection that is 90+ percent effective? Does he also shun less-than-100%-effective seat belts, birth control, tooth brushing, and the seasonal flu vaccine that his doctor surely recommends? To say bluntly what so many are wondering: Has Covid become a pandemic of the stupid? Lest we presume so, psychological science has repeatedly illuminated how even smart people can make not-so-smart judgments. As Daniel Kahneman and others have demonstrated, intelligent people often make dumb decisions. Researcher Keith Stanovich explains: Some biases—such as our favoring evidence that confirms our preexisting views—have “very little relation to intelligence.” So, if we’re not to regard the resilient anti-vax minority as stupid, what gives? If, with Spinoza, we wish not to ridicule but to understand, several psychological dynamics can shine light. Had we all, like Rip Van Winkle, awakened to the clear evidence of Covid’s virulence and the vaccine efficacy, surely we would have more unanimously accepted these stark realities. Alas, today’s science-scorning American subculture seeded skepticism about Covid before the horror was fully upon us. Vaccine suspicion was then sustained by several social psychological phenomena that we all experience. Once people’s initial views were formed, confirmation bias inclined them to seek and welcome belief-confirming information. Motivated reasoning bent their thinking toward justifying what they had come to believe. Aided by social and broadcast media, group polarization further amplified and fortified the shared views of the like-minded. Misinformation begat more misinformation. Moreover, a powerful fourth phenomenon was at work: belief perseverance. Researchers Craig Anderson, Mark Lepper, and Lee Ross explored how people, after forming and explaining beliefs, resist changing their minds. In two of social psychology’s great but lesser known experiments, they planted an idea in Stanford undergraduates’ minds. Then they discovered how difficult it was to discredit the idea, once rooted.  Their procedure was simple. Each study first implanted a belief, either by proclaiming it to be true or by offering anecdotal support. One experiment invited students to consider whether people who take risks make good or bad firefighters. Half looked at cases about a risk-prone person who was successful at firefighting and a cautious person who was not. The other half considered cases suggesting that a risk-prone person was less successful at firefighting. Unsurprisingly, the students came to believe what their case anecdotes suggested. Then the researchers asked all the students to explain their conclusion. Those who had decided that risk-takers make better firefighters explained, for instance, that risk-takers are brave. Those who had decided the opposite explained that cautious people have fewer accidents.  Lastly, Anderson and his colleagues exposed the ruse. They let students in on the truth: The cases were fake news. They were made up for the experiment, with other study participants receiving the opposite information. With the truth now known, did the students’ minds return to their pre-experiment state? Hardly. After the fake information was discredited, the participants’ self-generated explanations sustained their newly formed beliefs that risk-taking people really do make better (or worse) firefighters. So, beliefs, once having “grown legs,” will often survive discrediting. As the researchers concluded, “People often cling to their beliefs to a considerably greater extent than is logically or normatively warranted.” In another clever Stanford experiment, Charles Lord and colleagues engaged students with opposing views of capital punishment. Each side viewed two supposed research findings, one supporting and the other contesting the idea that the death penalty deters crime. So, given the same mixed information, did their views later converge? To the contrary, each side was impressed with the evidence supporting their view and disputed the challenging evidence. The net result: Their disagreement increased. Rather than using evidence to form conclusions, they used their conclusions to assess evidence. And so it has gone in other studies, when people selectively welcomed belief-supportive evidence about same-sex marriage, climate change, and politics. Ideas persist. Beliefs persevere. The belief-perseverance findings reprise the classic When Prophecy Fails study led by cognitive dissonance theorist Leon Festinger. Festinger and his team infiltrated a religious cult whose members had left behind jobs, possessions, and family as they gathered to await the world’s end on December 21, 1954, and their rescue via flying saucer. When the prophecy failed, did the cult members abandon their beliefs as utterly without merit? They did not, and instead agreed with their leader’s assertion that their faithfulness “had spread so much light that God had saved the world from destruction.” These experiments are provocative. They indicate that the more we examine our theories and beliefs and explain how and why they might be true, the more closed we become to challenging information. When we consider and explain why a favorite stock might rise in value, why we prefer a particular political candidate, or why we distrust vaccinations, our suppositions become more resilient. Having formed and repeatedly explained our beliefs, we may become prisoners of our own ideas. Thus, it takes more compelling arguments to change a belief than it does to create it. Republican representative Adam Kinzinger understands: “I’ve gotten to wonder if there is actually any evidence that would ever change certain people’s minds.” Moreover, the phenomenon cuts both ways, and surely affects the still-fearful vaccinated and boosted people who have hardly adjusted their long-ago Covid fears to the post-vaccine, Omicron new world. The only known remedy is to “consider the opposite”—to imagine and explain a different result. But unless blessed with better-than-average intellectual humility, as exhibited by most who accept vaccine science, we seldom do so. Yet there is good news. If employers mandate either becoming vaccinated or getting tested regularly, many employees will choose vaccination. As laboratory studies remind us, and as real-world studies of desegregation and seat belt mandates confirm, our attitudes will then follow our actions. Behaving will become believing.

In Exploring Psychology, 12th Edition, Nathan DeWall and I report that autism spectrum disorder (ASD) “is now diagnosed in 1 in 38 children in South Korea, 1 in 54 in the United States, 1 in 66 in Canada….” Check that. A new CDC report on 2018 data raises the continually increasing U.S. proportion to 1 in 44 (23 per 1,000 among 8-year-olds in eleven representative communities followed by the Autism and Developmental Disabilities Monitoring Network). The report also confirms that ASD diagnoses are four times more common among boys than girls. Psychologist Simon Baron-Cohen believes the gender imbalance is because boys tend to be “systemizers”: They more often understand things according to rules or laws, as in mathematical and mechanical systems. Girls, he contends, tend to be “empathizers”: They excel at reading facial expressions and gestures. And what racial/ethnic group do you suppose has the highest rate of ASD diagnoses? The answer: There are no discernible differences (nor across socioeconomic groups). In 2018, ASD was diagnosed equally often among all racial/ethnic groups. A final fact to ponder: 4-year-olds, the CDC reports, were “50 percent more likely to receive an autism or special education classification” than were 8-year-olds. So what do you think? Is the increasing ASD diagnosis rate—over time and of 4-year-olds—a a welcome trend? Is Karen Remley, director of the CDC’s National Center on Birth Defects and Developmental Disabilities right to regard this “progress in early identification” as “good news because the earlier that children are identified with autism the sooner they can be connected to services and support”? Or does the increased labeling of children become a self-fulfilling prophecy that assigns children to a category that includes some social deficiency, and then treats them differently as a result? And does the trend reflect some relabeling of children’s disorders, as reflected in the decreasing diagnoses of “cognitive disorder” and “learning disability”? (The popularity of different psychiatric labels does exhibit cultural variation across time and place.) In this COVID-19 era of anti-vax fears, this much we know for sure: One thing that does not contribute to rising ASD diagnoses is childhood vaccinations. Children receive a measles/mumps/rubella (MMR) vaccination in early childhood, about the time ASD symptoms first get noticed—so some parents naturally presumed the vaccination caused the ensuing ASD. Yet, despite a fraudulent 1998 study claiming otherwise, vaccinations actually have no relationship to the disorder. In one study that followed nearly 700,000 Danish children, those receiving the measles/mumps/rubella vaccine were slightly less likely to later be among the 6517 ASD-diagnosed children.

Consider the great COVID irony: As Surgeon General Vivek Murthy noted recently, “Vaccinated people may overestimate their peril, just as unvaccinated people may underestimate it.” Murthy could omit “may,” for we now have a string of national surveys (here, here, here, and here) showing that unvaccinated folks are much less likely to fear the virus. Moreover, those who are unvaccinated—and thus vastly more at risk of contracting and transmitting the virus—are also much less likely to protect themselves and others by wearing a mask. (If you see someone wearing a mask in your grocery store, they’re probably vaccinated.) Unvaccinated people’s discounting the threat, distrusting science, and prioritizing their rights to be unvaccinated and unmasked provide us social psychologists with a gigantic case study of unrealistic optimism, motivated reasoning, and group polarization. But looking forward, we can offer a prediction: As vaccine mandates increase, inducing more people to accept vaccination rather than being excluded from events or flights or bothered with weekly testing, attitudes will follow behavior. As every student of psychological science knows, two-way traffic flows between our attitudes and our behavior. We will often stand up for what we believe. But we also come to believe in what we stand up for. When people are induced to play a new role—perhaps their first days in the military or on a new job—their initial play-acting soon feels natural, as the new actions become internalized. When, in experiments, people are induced to support something about which they have doubts, they often come to accept their words. And in the laboratory, as in life, hurtful acts toward another foster disparagement, while helpful acts foster liking. In short, we not only can think ourselves into action, but also act ourselves into a new way of thinking. Behaving becomes believing. The attitudes-follow-behavior phenomenon is strongest in situations where we feel some responsibility for our action, and thus some need to explain it to ourselves—resolving any dissonance between our prior thinking and our new behavior. But the federal mandate—get vaccinated or face weekly testing—does (smartly) preserve some choice. What is more, we have ample historical evidence of mandates swaying public opinion. In the years following the 1954 Supreme Court school desegregation decision and the 1964 Civil Rights Act, White Americans—despite initial resistance—expressed steadily diminishing prejudice. Some resisted, and hate lingers. Yet as national anti-discrimination laws prompted Americans in different regions to act more alike, they also began to think more alike. Seat belt mandates, which at first evoked an angry defense of personal liberty, provide another example of attitudes following actions. Here in Michigan, the state representative who introduced the state’s 1982 seat belt law received hate mail, some comparing him to Hitler—despite abundant evidence that, like today’s vaccines, seatbelts save lives. But time rolls on, and so did seat belt acceptance, with Michigander’s approval of the law rising to 85 percent by the end of 1985 and usage rising from 20 percent in 1984 to 93 percent by 2014. Ditto other government policies, such as Social Security and Medicare—once contentious, now cherished. So amid the rampant information there is good news: Mandates can work. They can get people to protect themselves and others, as  have nearly all United Airlines employees and New York health care workers. And after doing so, people will tend to embrace the way things are. (For David Myers’ other essays on psychological science and everyday life, visit TalkPsych.com.

In the United States, anti-Asian prejudice has resurged, with nearly 6,600 hate incidents against Asian Americans and Pacific Islanders (AAPIs) recorded during the COVID-19 pandemic’s first year. Reports of harassment, vandalism, and brutal attacks on Asian Americans, from the very young to the very elderly, have made one-third of Asian Americans fear for their safety. An Asian-American friend last week recounted his fearful father getting a gun for self-protection. Women and girls reportedly endured two-thirds of these hostilities, including the horrific March, 2021 Atlanta shooting spree that claimed the lives of eight people—six of them Asian American women. One in four AAPI-owned small businesses has also faced pandemic-related anti-Asian words or acts. Today’s bigotry extends a long history, beginning with the 20th century’s ground zero event of anti-Asian prejudice: the World War II exclusion of 120,000 West Coast people of Japanese descent. As I have explained here and here, it was on my home island—Bainbridge Island, near Seattle—that the relocation and incarceration of Japanese Americans began. With only six days’ notice, Exclusion Order #1 ordered the evacuation of the island’s 276 Japanese American residents, each lugging nothing more than they could carry. (One government concern: The island’s south end overlooked a narrow passage to a naval shipyard and submarine base.) Today, that March 30, 1942 ferry departure point is the site of a national “Japanese American Exclusion Memorial.” On each visit home to Bainbridge, I return to the memorial, where a 276-foot wall with wood sculptures tells parts of the story. As my insurance agent father would later recall, it was a devastating day as the islanders bid farewell to their neighbors. His autobiography recalls the sadness, and also the lingering discrimination: “We had many Japanese friends and it was heartbreaking for us when the war started and the Japanese people on Bainbridge Island were ordered into concentration camps. . . . Most were educated here on the island [and] it was hard to believe that they were not as loyal Americans as we. I did all I could to keep the insurance on their homes in force. . . . The insurance companies that I represented were a bit prejudiced against insuring the Japanese people, particularly for liability insurance, for fear that lawsuits would be brought against them and the juries, being Caucasian, might be prejudiced in their jury awards. [One post-war returnee, wanting insurance on a car] named his four brothers and recited how all five of them had been in one or another of the American armed forces and had served in Italy, France, Germany and Japan. [When I showed the letter to the insurance manager] she said G___ D___ you, Ken Myers, for bringing me this letter. How can I say, ‘No’? So she wrote the first policy on a Japanese American after the war.” In contrast to the media-fomented bigotry that greeted other West Coast internees on their post-war return home, the Bainbridge internees were welcomed back by most. On my recent visit to the Memorial, I chanced to meet internee Lilly Kodama recalling her experience, as a seven-year-old, of being abruptly taken from her world. She presumed she was going with her family on a shopping trip, and was surprised to find her cousins and neighbors on the dock. But Kodama also spoke of the support of fellow islanders, including my father, but especially Walt and Millie Woodward, the heroic local newspaper owners who challenged the exclusion and then published news from the camps. The Bainbridge Island contrast illustrates what social psychologists have often reported: Social contact, especially between parties of equal status, restrains prejudice. In minimal-contact California, people of European descent and people of Japanese descent lived separately. Few people bid the departing internees goodbye. On their return, “No Japs Here” signs greeted them. Minimal contact enabled maximal prejudice. On high-contact Bainbridge, islanders intermingled as school classmates (as illustrated in this 1935 elementary school picture). Their homes, strawberry farms, and businesses were dispersed. In their absence, thirteen empty chairs were on stage at a high school graduation so all would remember who was missing. Internees returning after the war were greeted with food and assistance. Cooperative contact enabled minimal prejudice. Lincoln Elementary School photo courtesy Bainbridge Island Historical Museum This real-life social experiment has been replicated in our own time: People in states with the least immigrant contact express the most anti-immigrant antipathy, while those who know immigrants as neighbors, classmates, or fellow workers more often profess a welcoming attitude. Amid the anti-Asian prejudice of 2021, how can we replace incidents of closed fists and tight jaws with open arms? We can seek and facilitate intergroup contacts. We can travel and experience other cultures. We can welcome diversity into our communities and workplaces. We can challenge slurs. We can educate ourselves and others about our culture’s history. In such ways we can affirm the memorial’s closing words: P.S. Frank Kitamoto, after being taken from the island as a 2-year-old and later founding the Bainbridge Island Japanese American Community, recalled fellow islanders' support in this 2-minute video.

Meet Jack and Jill as they march up the hill to buy a new vehicle. Hoping to save gas costs and benefit the environment, they are wavering between two options: trading their 34-mpg sedan for a 56-mpg Toyota Prius Eco. trading their hefty 12-mpg pickup truck for a 14-mpg Toyota Tundra. Question: Assuming they drive both vehicles the same number of miles, which purchase would most reduce their gas consumption? Most folks—you, also?—think the Prius would save more. After all, a 34- to 56-mpg jump is a 65 percent improvement, whereas a 12- to 14-mpg jump is but a 17 percent improvement. I thought so, too, until a  mutual friend alerted me to social psychologist (and Duke business professor) Richard Larrick’s studies of the MPG illusion (see here and here). To see the MPG illusion in action, let’s do the math, assuming that Jill and Jack drive each car 15,000 miles a year and pay $3.00 per gallon for gas: The 34-mpg sedan now consumes 15,000 ÷ 34 = 441 gallons; the new 56-mpg Prius would consume 15,000 ÷ 56 = 268 gallons. That’s 173 gallons and $519 saved. The 12-mpg pickup presently scarfs 15,000 ÷ 12 = 1250 gallons, compared with the Tundra’s 15,000 ÷ 14 = 1071 gallons. That’s 179 gallons and $537 saved. The bottom line: A 2-mpg increase when purchasing or replacing a low-mileage car is hugely more beneficial—to the environment and to one’s pocketbook—than a 2-mpg increase when purchasing a high-mileage car. As Larrick says (but most folks don’t appreciate), “small MPG improvements on inefficient cars can save a lot of gas.” We can cure the MPG illusion by reframing reported fuel efficiency as GPM—gallons per mile, rather than MPG—miles per gallon. When buying, isn’t that what we need to know: not how far can we drive on a gallon, but rather how many gallons must we buy to drive this car? MPG is also useful—it tells us whether we can make it home before needing to refuel. But when purchasing a car, it’s gas consumption, not MPG, that matters most. In recognition of the MPG illusion—the perception that equal MPG increases will represent equal gas savings—the U.S. Department of Energy now includes, albeit less prominently, GPM information on fuel economy labels (#5, below). Larrick and his colleague Jack Soll report that when people stop to consider the GPM framing, most do then make fuel-smart judgments. And when people think smarter about fuel savings—when, for example, they realize that increasing fuel efficiency from 10 to 20 mpg will save twice as much as a 20 to 40 mpg increase—public energy conservation policies can become smarter as well. GPM framing helps us prioritize getting the most fuel-inefficient vehicles out of sales rooms and off the road. P.S. For fellow data geeks, U.S. “Miles per hour” are increasing: (For David Myers’ other essays on psychological science and everyday life, visit TalkPsych.com.) ... View more
