Several prominent psychologists have recently raised concerns that the “radical left” has a stranglehold on free speech and thought in our universities. The psychologists argue this includes biological denialism: claims that differences between individuals and groups are entirely the result of the biased system or mere social constructions. More generally, many commentators are horrified by the apparent resurgence of far-right ideologies and their twisted interpretation of genetic science.

It’s timely, then, that a team of researchers, led by psychologist Emily Willoughby at the University of Minnesota Twin Cities, recently surveyed over 1000 online US participants, asking them about their personal circumstances, education, political orientation, and also to estimate the relative contribution of genes and the environment to variation in 21 different human traits, from eye colour to intelligence. This is probably the most detailed study to date of people’s insights into behavioural genetics, and the findings have just been published as a pre-print at the Open Science Framework.

New findings pose more problems for the embattled concept of the microaggression

“Microaggressions” are seemingly innocuous words or behaviour that supposedly communicate a bias toward minority groups, such as asking Asian Americans where they are from, implying that they are not really part of the USA. According to advocates of the usefulness of the concept, microaggressions cause real harm, even if unintended by the perpetrator. However, the theoretical and evidential support for the concept of microaggressions is far from clear, as detailed in Scott Lilienfeld’s recent thorough critique, which recommended the term be revised or at least re-examined. Now, Craig Harper, a psychologist at Nottingham Trent University, has published a study as a pre-print online at PsyArXiv that, he argues, reveals a further key problem with the concept of the microaggression.

Fake news leaves a lasting impression on the less smart

By Alex Fradera

One reason why fake news is dangerous is that we don’t like giving up reassuring certainties, and once we have a take on things, it colours further information – hence the seeming bulletproof nature of conspiracy theories and partisan political hatreds. But new research in Intelligence suggests this is truer for some people than others. For mentally sharp people, the results suggest it’s relatively easy to jettison an outdated perspective, while for those of lower cognitive ability, the dregs remain.

Can evolutionary psychology and personality theory explain Trump’s popular appeal?

GettyImages-632198430.jpgBy Christian Jarrett

One year ago today, Donald J Trump, a man with no political or military experience, defied expectations, winning the election to become the 45th president of the United States. Nearly 63 million voted for him, including, and in spite of his reputation for sexism, over half of all white women. In an open-access paper in Evolutionary Studies in Imaginative Culture, Dan McAdams, one of the world’s leading experts in personality psychology, proposes an explanation for Trump’s popular appeal that is grounded in evolutionary psychology, personality theory and the social psychology of leadership.

We know intuitively how many lay opinions outweigh an expert

“People in this country have had enough of experts” claimed Michael Gove last year. New findings suggest we weigh popular and expert opinion intuitively

By Alex Fradera

Imagine contemplating which treatment to undertake for a health problem. Your specialist explains there are two possibilities, and strongly endorses one as right for you. But when you discuss it with a friend, she suggests that based on what she’s heard, the other would be better. Another friend, the same. And another. Does there come a point where the friends outweigh the expert? Given enough information – the accuracy of the expert in the past, the degree to which the public have any insight on the issue – you can in theory mathematically “solve” this issue with a probabilistic model. In fact, according to new research published in Thinking and Reasoning, that’s exactly what we do intuitively and with a high degree of accuracy.

In or out – how brain activity can predict your vote on Brexit

People’s brain responses to statements about the EU were a more accurate predictor of how they voted than their stated intentions

By guest blogger Helge Hasselmann

Surveys and opinion polls are notoriously bad at predicting election results, as a chain of rather unexpected events last year demonstrated. These instruments usually ask people about their explicit attitudes and opinions. Often, however, these “external” proxies are not entirely representative of what a person is really thinking. For example, several studies have shown that implicit attitudes – that is, subtle preferences or biases outside the realm of our consciousness – can be more useful in predicting our future choices.

As scary as this may sound, there is also mounting evidence that our physiological responses can be even more accurate in revealing how we’re likely to vote. In a new paper in Social Cognitive and Affective Neuroscience, researchers from Kingston University and the University of Essex have taken a closer look at a voting outcome in the UK that, last year, came as a surprise to a lot of people. Their findings suggest that people’s brain responses to statements about the EU were a more accurate predictor of they way they went on to vote in the Brexit referendum than their stated intentions.

Psychologists went to war-torn Northern Iraq to find out why some fighters will sacrifice everything for their cause

Why are some people willing to risk their own lives – and even their children’s lives – to fight an enemy? An extraordinary study involving interviews with frontline fighters against the Islamic State, as well as IS fighters, finds that three crucial factors are at play. The most important was the strength of commitment to a “sacred” or deeply-held value or idea – but not necessarily a religious one. The findings “may help to inform policy decisions for the common defense,” wrote Ángel Gómez and his colleagues in their new paper in Nature Human Behaviour.

We have an ingrained anti-profit bias that blinds us to the social benefits of free markets

“Harnessing the ‘base’ motive of material self-interest to promote the common good is perhaps the most important social invention mankind has yet achieved,” said the American economist Charles Schultz. And you can see why. While acknowledging its problems, many credit free market capitalism for the dramatic reduction over recent decades in the proportion of people in the world living in extreme poverty, not to mention rising health standards and technological advances. Conversely, according to some commentators, one only has to look to modern-day Venezuela to see the dangers of extreme anti-profit socialism.

And yet, according to a new paper in Journal of Personality and Social Psychology, most of us have an instinctual anti-profit bias. We view for-profit companies and industries – upon which capitalism is based – with inherent distrust, assuming that the more profitable they are, the more harm they do to society. In fact, research shows the opposite is true: companies that make greater profits actually tend to contribute more value to society, for example in terms of their environmental responsibility and corporate philanthropy.

The authors of the new paper, led by Amit Bhattacharjee at Erasmus University, believe this anti-profit bias leads many voters and politicians to endorse anti-profit policies that are likely to lead to the very opposite outcomes for society that they want to achieve. “Erroneous anti-profit beliefs may lead to systematically worse economic policies for society, even as they help people satisfy their social and expressive needs on an individual level” they said.

Politicians – when you dodge the question, it makes you look dodgy
Party Leaders Appear On Live Televised Show 'May v Corbyn Live: The Battle for Number 10'
The research also suggested that we’re more likely to notice evasions by politicians whom we distrust

By Alex Fradera

Evasive politicians tend to pay for their slipperiness, according to new research in Journal of Language and Social Psychology. To study the art of the dodge, David Clementson of Ohio State University created videos of a male politician with no obvious party affiliation (he was played by an actor, but the participants thought he was a real politician), who was quizzed on a number of topics by a news reporter. In some versions of the video the politician played it entirely straight, but in others he dodged one of the questions, either by switching topics, or by giving a terse “no comment”. Either evasion led to the politician being rated as less trustworthy, both by a young group of 200 American university students, and a more seasoned group of 200 US citizens with an average age of 57.

Online purchase patterns show left-wingers and right-wingers read very different science books

The partisan consumption of science may contribute to opposing views on important issues

By Alex Fradera

With political tribalism a feature of our times, perhaps science could act as a unifying force. While faith in politicians and journalists is in the doldrums, surveys in countries like Britain, Canada and the US suggest scientists are among the most respected professions, and citizens are appreciative of the contribution science makes to their lives. As the authors of a recent article in Nature Human Behaviour note, it seems that “we may disagree on emotionally charged social issues, but at least we can agree on science”.  Sadly, their findings show that it’s not so simple. Although politically diverse people may be fans of science, we’re not fans of the same science.
