These are strange, unsettling times. And for the past several    months, Ive been asking psychologists variations on a basic    question: What research can best help us reckon with    uncomfortable social and political realities  like the rise of    Donald Trump, the widening partisan split, the divisiveness    that comes with multiculturalism?  
    More than ever before, people of different ideological    backgrounds seem to live in separate universes. One example: In    the days after the inauguration, social scientists showed    participants photos of Trumps inaugural crowd and Obamas.    Those who had voted for Trump were more likely to say Trump had    the larger turnout, despite obvious     differences in the photos that demonstrated otherwise.  
    Psychology can help explain these tense times. Old theories,    like motivated reasoning, are more clearly true than ever    before. And new work has confirmed that humanity still contains    its same base instincts of the prehistoric era.  
    Consider this a primer. Here are seven essential lessons on the    hidden forces shaping our views and actions in the Trump era.  
    If you think I missed something that should be on    this list, send me an email:    brian@vox.com  
    One of the key psychological concepts for understanding    politics is also one of the oldest.  
    Its called motivated cognition, or motivated reasoning. And    theres no clearer example than in a paper published way back    in the 1950s.  
    The Dartmouth versus Princeton football game of November 1951    was, by all accounts, brutal. One Princeton player broke his    nose. One Dartmouth player broke his leg.  
    Princeton students blamed the Dartmouth team for instigating.    The Dartmouth paper accused Princetons. In the contentious    debates that ensued about "who started it," psychologists at    the two schools united to    answer this question: Why did each school have such a    different understanding of what happened?  
    In the weeks after the Princeton-Dartmouth game, the    psychologists Albert Hastorf and Hadley Cantril ran a very    simple test. Their findings would become the classic example of    a concept called motivated reasoning: Our tendency to come to    conclusions were already favored to believe.  
    When they asked students at each of their universities to watch    video highlights from the game, 90 percent of the Princeton    students said it was Dartmouth that instigated the rough play.    Princeton students were also twice as likely to call penalties    on Dartmouth than their own team. The majority of Dartmouth    students, on the other hand, said both sides were to blame for    the rough play in the game, and called a similar number of    penalties for both teams. Hastorf and Cantrils conclusion    wasnt that one set of fans was lying. Its that being a fan    fundamentally changes the way you perceive the game.  
    The lesson is simple: People are more likely to arrive at    conclusions  that they want to arrive at, the psychologist    Ziva Kunda wrote    in a seminal 1990 paper, making the case that motivated    reasoning is real and pervasive.  
    And theres plenty of proof of it today. When Gallup     polled Americans the week before and the week after the    presidential election, Democrats and Republicans flipped their    perceptions of the economy. But nothing had actually changed    about the economy. What changed was which team was winning.  
    Motivated reasoning plays into why people from poor communities    were willing to vote for Trump, a candidate whose party is keen    to pare back the social safety net and has a proposed a health    care bill that will lead to millions more becoming uninsured.  
    One crucial thing to know about motivated reasoning is that you    often dont realize youre doing it. We automatically have an    easier time remembering    information that fits our world views. Were simply quicker    to recognize information that confirms what we already know,    which makes us blind to facts that discount it.  
    None of this psychology is to suggest that people who engage in    motivated reasoning are stupid. No, they are just human. For    example, a lot of evangelicals voted for Trump because of the    simple fact he was the Republican presidential candidate,    despite having reason to dismiss him after the Access    Hollywood tape where he bragged about sexual     assault leaked. Republican is the political team they play    on. And that allowed them to find ways to justify their    support.  
    Motivated reasoning can affect anyone, and liberals do it, too.    Some are retweeting rogue federal Twitter accounts that have    no verification that theyre     indeed written by disgruntled federal staffers. At the    Atlantic, Robinson Meyer     asked Brooke Binkowski, the head of fact-checking website    Snopes.com, if fake news    targeted toward liberals is on the rise. Of course yes! she    said. (See some examples     here.)  
    Lets remember that.  
    If a group of people have the same, solid grounding in the same    facts about politics, then everyone should come to the same    conclusions, right? Wrong.  
    Study after study has shown that this assumption is not    supported by the data, says Dietram    Scheufele, who studies science communication at the    University of Wisconsin.  
    In fact, studies show the exact opposite: The more    informed people are about politics, the more likely    they are to be stubborn about political issues.  
    This concept is related to motivated reasoning, but its    important enough to warrant its own consideration. It shows how    motivated reasoning becomes especially stubborn and ugly when    it comes to politics.  
    People are using their reason to be socially competent    actors, says Dan Kahan, a psychologist at Yale, and one of the    leading experts on this phenomenon. Put another way: We have a    lot of pressure to live up to our groups expectations. And the    smarter we are, the more we put our brain power to use for that    end.  
    In his studies, Kahan will often give participants different    kinds of math problems.  
    When the problem is about nonpolitical issues  like figuring    out the whether a drug is effective  people tend to use their    math skills to solve it. But when theyre evaluating something    political  lets say, the effectiveness of gun control    measures  the trend is that the better participants are at    math, the more partisan they are in their responses.  
    Partisans with weak math skills were 25 percentage points    likelier to get the answer right when it fit their ideology,    Ezra Klein     explained in a profile of Kahans work. Partisans with    strong math skills were 45 percentage points likelier    to get the answer right when it fit their ideology. The smarter    the person is, the dumber politics can make them.  
    And its not just for math problems: Kahan finds that    Republicans who have higher levels of     science knowledge are more stubborn when it comes to    questions on climate change. The pattern is consistent: The    more information we have, the more we bend it to serve our    political aims. Thats why the current debate over fake news    is a bit misguided: Its not the case that if only people had    perfectly true information, everyone would suddenly agree.  
    So think of that when you hear politicians or pundits talk    shop: They know a lot about politics, but theyre bending what    they know to fall in line with their political goals. And they    probably dont realize they are doing this and can feel    confident in their partisan conclusions because they feel well    informed.  
    Theres a reason why we engage in motivated reasoning, a reason    why facts often dont matter: evolution.  
    Critical thinking and reasoning skills evolved because they    made it easier to cooperate in groups, Elizabeth Kolbert    explains in a recent New Yorker     piece. Weve since adapted these skills to make    breakthroughs in topics like science and math. But when    pressed, we default to using our powers of mind to get along    with our groups.  
    Psychologists theorize thats because our partisan identities    get mixed up with our personal identities. Which would mean    that an attack on our strongly held beliefs is an attack on the    self.  
    The brains primary responsibility is to take care of the    body, to protect the body, Jonas Kaplan, a psychologist at the    University of Southern California, says. The psychological    self is the brains extension of that. When our self feels    attacked, our [brain is] going to bring to bear the same    defenses that it has for protecting the body.  
    Its like we have an immune system for uncomfortable thoughts.  
    Recently, Kaplan has found more evidence that we tend to take    political attacks personally. In a study    recently published in Scientific Reports, he and    collaborators took 40 self-avowed liberals who reported having    deep convictions, put them inside in a functional MRI    scanner, and started challenging their beliefs. Then they    watched which parts of the participants brains lit up.  
    Their conclusion: When the participants were challenged on    strongly held beliefs, there was more activation in the parts    of the brain that are thought to correspond with self-identity    and negative emotions.  
    Theres a dynamic playing out in the current health care    debate, and in health care debates of ages past. Liberals make    their arguments for expanding coverage in terms of equality and    fairness (i.e., everyone should have a right to health care),    while conservatives make their case grounded in    self-determination (i.e., the government shouldnt tell    me how to live) and fiscal security (i.e., paying for    health care will bankrupt us all).  
    According to a psychological theory called moral foundations,    its no surprise that these arguments fail spectacularly at    changing minds.  
    Moral foundations is the idea that people have stable,    gut-level morals that influence their worldview. The liberal    moral foundations include equality, fairness, and protection of    the vulnerable. Conservative moral foundations favor in-group    loyalty, moral purity, and respect for authority.  
    These moral foundations are believed to be somewhat consistent    over our lifetimes, and they may have a biological basis as    well. (Theres some     fascinating experimental work that shows that conservatives    are more excited  as measured by perspiration  by negative or    alarming images.)  
    Moral foundations explain why messages highlighting equality    and fairness resonate with liberals and why more patriotic    messages like make America great again get some conservative    hearts pumping.  
    The thing is, we often dont realize that people have moral    foundations different than our own.  
    When we engage in political debates, we all tend to overrate    the power of arguments we find personally convincing  and    wrongly think the other side will be swayed.  
    On gun control, for instance, liberals are persuaded by stats    like, "No other developed country in the world has nearly the    same rate of gun violence as does America." And they think    other people will find this compelling, too.  
    Conservatives, meanwhile, often go to this formulation: "The    only way to stop a bad guy with a gun is a good guy with a    gun."  
    What both sides fail to understand is that they're arguing a    point that their opponents may be inherently deaf to.  
    In a     study, psychologists Robb Willer and Matthew Feinberg had    around 200 conservative and liberal study participants write    essays to sway political opponents on the acceptance of gay    marriage or to make English the official language of the United    States.  
    Almost all the participants made the same mistake.  
    Only 9 percent of the liberals in the study made arguments that    reflected conservative moral principles. Only 8 percent of the    conservative made arguments that had a chance of swaying a    liberal.  
    No wonder why its so hard to change another persons mind.  
    Nour Kteily, a psychologist at Northwestern University,    conducts research on one of the darkest, most ancient, and most    disturbing mental programs encoded into our minds:    dehumanization, the ability to see fellow men and women as less    than human.  
    Psychologists are no strangers to this subject. But the    prevailing wisdom has been that most people are not willing to    admit to having prejudice against others.  
    Wrong.  
    In Kteilys studies, participants  typically groups of mostly    white Americans  are shown this (scientifically     inaccurate) image of a human ancestor    slowly learning how to stand on two legs and become fully    human. And then they are told to rate members of different    groups  such as Muslims, Americans, and Swedes  on how    evolved they are on a scale of 0 to 100.  
    Many people in these studies give members of other groups a    perfect score, 100, fully human. But many others give others    scores putting them closer to animals.  
    With the Ascent of Man tool, Kteily and collaborators Emile    Bruneau, Adam Waytz, and Sarah Cotterill found that, on    average, Americans rate other Americans as being highly    evolved, with an average score in the 90s. But disturbingly,    many also rated Muslims, Mexican immigrants, and Arabs as less    evolved.  
    We typically see scores that average 75, 76, for Muslims,    Kteily says. And about a quarter of study participants will    rate Muslims on a score of 60 or below.  
    People who dehumanize are more likely to blame Muslims as a    whole for the actions of a few perpetrators. They are more    likely to support policies restricting the immigration of Arabs    to the United States. People who dehumanize low-status or    marginalized groups also score higher on a measure called    social dominance orientation, meaning that they favor    inequality among groups in society, with some groups dominating    others.  
    And, in a study,    blatant dehumanization of Muslims and Mexican immigrants was    strongly correlated with Trump support  and the correlation    was stronger for Trump than any of the other Republican    candidates.  
    In the lead-up to the 2016 election, fear seemed to be    everywhere.  
    After the terrorist attacks in Paris and Brussels, Donald Trump    and conservative allies redoubled their promises to make    borders more secure and ban whole religious groups from the    country. Trumps rhetoric often underscored an us-versus-them    mentality  illegal immigrants from Mexico were raping our    people; countries like China were destroying us on trade.  
    A lot of new psychological evidence suggests that stoking    peoples racial and demographic fears helped Donald Trump win    votes.  
    Negative, scary information is almost always more sticky and    memorable than positive information  
    One of those studies     explored the question of what white people feel when they    are reminded that minorities will eventually be the majority.    And it found that they begin to feel less warm toward members    of other races. A more recent     experiment showed that reminding white people of this trend    increased support for Trump.  
    What this doesnt mean is that all white people harbor extreme    racial animus. It means fear is an all-too-easy button for    politicians to press. We fear unthinkingly. It directs our    actions. And it nudges us to believe the person who says he    will vanquish our fears.  
    People who think of themselves as not prejudiced (and liberal)    demonstrate these threat effects, says Jennifer Richeson, a    leading researcher on racial bias.  
    Theres also this fact to contend with: Negative, scary    information is almost always more sticky and memorable than    positive information. Negative events capture attention and    information processing more readily, elicit strong emotions    more easily, and are more memorable, psychologists Daniel    Fessler, Anne Pisor, and Colin Holbrook, wrote in a recent        study.  
    They showed participants 14 plausible but false statements,    like Kale contains thallium, a toxic heavy metal, that the    plant absorbs from soil. Some of the statements, like the one    above, implied a warning (dont eat Kale!), others were    positive, like Eating carrots results in significantly    improved vision.  
    Participants often found the threatening statements more    credible than the non-threatening one, and this was especially    true among more conservative participants (and especially true    for social conservatives, as compared to fiscal conservative).    This is not because conservatives are more gullible. Its    because they tend to be more vigilant.  
    Savvy politicians understand this, and craft messages that    stoke that innate vigilance (whether concern is warranted or    not). Its hard to blame people for being afraid of threats.    Its just in our nature. But you can blame politicians who prey    on it.  
    Other researchers have arrived at similar findings.  
    Last year, Willer and Feinberg published    a paper that found that racial attitudes predicted support for    the conservative Tea Party movement. In one study, they showed    participants an artificially darkened portrait of President    Barack Obama  to maximally remind participants hes African    American. White participants shown the darkened photo were    more likely to report they supported the Tea Party relative to    a control condition, the study reported.  
    Similarly, they found that reminding study participants about a    coming minority-majority America made them more likely to    support the Tea Party platform.  
    In the 1960s, Stanford psychologist Albert Bandura showed how    easy it is to teach kids to act violently  by showing them an    adult acting violently.  
    In this famous experiment, Bandura showed young children     between 3 and 6 years old  a video of an adult wailing on an    inflatable bobo doll (see in the video below). Other children    in the study did not see an adult behaving aggressively to the    doll.  
    And sure enough: The kids who saw the aggressive behavior were    more aggressive themselves when playing with the doll later on.  
    Its a simple experiment with a simple conclusion: As humans,    even at an early age  we learn whats socially acceptable by    watching other people.  
    Lately, weve been witnessing     an unsettling number of brazen hate crimes and vandalism    against Muslim and Jewish institutions. Its hard to directly    link these crimes to the charged political climate. But like    Banduras experiment, theres evidence that social norms    against prejudice change when people in power start talking and    behaving badly.  
    Some psychologists think Trumps rhetoric and the rise of the    alt-right movement that supported him are similarly encouraging    people with prejudicial views to act upon them.  
    I dont think Trump created new prejudices in people  not    that quickly and not that broadly  what he did do is change    peoples perceptions about what is okay and what is not okay,    University of Kansas psychologist Chris Crandall says.  
    Recently Crandall and his student Mark White asked 400 Trump    and Clinton supporters to rate how normal it is to disparage    members people of various marginalized groups  like the obese,    Muslims, Mexican immigrants, and the disabled  both before the    election and in the days after.  
    Both Clinton and Trump supporters were more likely to report it    was acceptable to discriminate against these groups after the    election. For Trump to say the disparaging things he said    during the campaign, and then be rewarded for them, sent a    powerful sign.  
    It took away the suppression from the very highly prejudiced    people, Crandall said. And those are people acting.  
    These results are preliminary (i.e., not yet published in a    journal), but theyre reflective of the established literature:    Exposure to misbehavior simply makes it more acceptable.  
    Heres one example. In 2004, sociologists Thomas Ford and Mark    Ferguson     found that exposure to a racist or sexist joke increased    tolerance of further discrimination in people who held    prejudicial views. Hearing the off-color joke, they write,    Expands the bounds of appropriate conduct, creating a norm of    tolerance of discrimination.  
    Theres still many more questions psychologists want to answer    about this political age. Its not enough to define problems in    prejudice and reasoning, psychologists are also seeking to    solve them. But many answers are still out of reach.  
    Psychology has been called the hardest    science because the human mind comes with so many messy    inconsistencies that even the top researchers can get tangled    up in. It can take decades to establish a psychological theory,    and in just months,     new evidence can tear it down. Despite its flaws,    psychology is still the best scientific tool we have to    understand how human behavior shapes the world.  
    There are a lot more concepts in psychology that can help us    understand whats going on in the world of politics. Here are a    few more worth learning about.
