People Who Are Most Fearful Of Genetically Modified Foods Think They Know The Most About Them, But Actually Know The Least

There are few subjects where a larger gap exists between public opinion and expert opinion than people’s views on foods, like corn or wheat, that have been genetically manipulated to, for example, increase crop yields or bolster pest-resistance. Experts generally view so-called GM foods as totally safe to consume, while the public is suspicious of them — and this divide is massive. One Pew Research Center survey found that just 37 per cent of the American public believed GM foods are safe to eat, compared with 88 per cent of members of the American Association for the Advancement of Science (public attitudes are similarly negative in the UK, with a 2014 poll finding that 40 per cent of adults felt the government should not promote GM foods, compared with 22 per cent in favour, and the rest unsure).

Unlike some subjects where this divide between layperson and expert opinion is heavily mediated by politics, such as climate change caused by human activity — in the U.S. and elsewhere, conservatives are far less likely to believe in it than are liberals and climate scientists — the GM-food divide doesn’t really have a political dimension: Liberals, centrists, and conservatives are all about equally likely to have what are, from the point of view of experts, unfounded fears about the safety of GM foods.

To better understand the source of these fears, a team led by Philip M. Fernbach, a professor at the Leeds School of Business at the University of Colorado Boulder, surveyed nationally representative samples in America, Germany and France, and other online participants, about their views on both GM foods and climate change, tested their knowledge on these subjects by asking them to answer factual questions, and also asked them to gauge their perceived level of knowledge on those subjects.

The headline finding from the study, published as a letter in Nature Human Behaviour, is neatly summed up by its title: “Extreme opponents of genetically modified foods know the least but think they know the most.” That is, on average, the more vehemently a given respondent said they were opposed to GM foods, the fewer questions about the subject they answered accurately, and the higher they rated their own knowledge.

Study Compares Trump’s Personality With Other Populist Leaders And Finds He Is An “Outlier Among The Outliers”

Talk of personality in politics is often dismissed as idle gossip, but politicians’ personalities inform their policy choices, shape their campaigning style and predict their chances of electoral success.

In fact, there has been much speculation that personality may be key to understanding perhaps the biggest electoral shock ever – Donald Trump’s triumph in the 2016 US Presidential election. Many commentators have highlighted Trump’s unusually brash, extraverted and narcissistic personality and proposed that it may partly explain his appeal among some voters. However, before now, there has been little systematic evidence to support this claim.

A new open-access paper in Presidential Studies Quarterly addressed this lack of evidence, surveying 875 international experts about the personality traits of 103 political leaders, including Trump and 20 other populists, who took part in 47 elections in 40 countries around the world between 2015 and 2016. Alessandro Nai and his colleagues found that Trump’s traits were rated at the extremes even in comparison to other populist leaders, suggesting a “truly unique and off-the-charts public persona”.

Blinded By Ideology: People Find It Difficult To Think Logically About Arguments That Contradict Their Politics

By Jesse Singal

A heated political story in the United States last weekend perfectly illustrates how tribal politics can supercharge a human weakness that psychologists have been studying for some time – our deep-seated tendency to accept evidence that supports our existing beliefs, and to ignore evidence that contradicts them.

It involved a conflict near the Lincoln Memorial featuring a handful of Black Israelites (a radical black nationalist group), a large group of mostly White American high-schoolers, some in Donald Trump hats, who were in town for an anti-abortion march, and a small group of Native American protesters, one of whom found himself in the midst of the high-schoolers.

Following the initial reports of what happened, and spurred along by a short video and dramatic photos, suggesting that the teens had encircled and confronted the Native American protester in an apparent act of intimidation, there was widespread condemnation of the teenagers, calls for them to be suspended or expelled from school, doxxed, and so on. But what’s telling is that when new details emerged, most notably the emergence of a longer video showing it was the protester who had waded into the sea of teens (because, he said later, he wanted to break up the conflict between them and the Black Israelites), and which complicated other aspects of the narrative as well, still many commentators continued to interpret events in line with their own political leanings. In fact the cacophonous online argument about what happened only seemed to explode in volume when the longer video was released — more information didn’t resolve things. At all.

As the Georgetown University professor Jonathan Ladd put it so well on Twitter: “Regarding the incident at the Lincoln Memorial,” he wrote, “it’s fascinating to see motivated reasoning play out in real time over a 24 hr period … Despite lots of video, all interpretations now match people’s partisanship.”

These politically motivated cognitive gymnastics are the subject of an important new paper lead-authored by Anup Gampa and Sean P. Wojcik that’s just been made available as a preprint (and due to be published in Social Psychological and Personality Science). Specifically, Gampa and Wojcik, working with a team that includes the open-science advocate Brian Nosek, decided to test the effects of politically motivated reasoning using logical syllogisms, a type of logical argument in which premises are assumed to be true, and arguments proceed from there.

Against expectations, people with more egalitarian political views were more open to the idea that intelligence is fixed

By Alex Fradera

A growth mindset – believing your capabilities can grow over time – can help us set self-improvement goals, consider mistakes as a step towards mastery, and remain upbeat when facing tribulation. Psychologists are excited by the ways we can help develop such mindsets, particularly towards creativity and intelligence, but some studies have found the impact less impressive than earlier research had suggested. Now researchers are hungry to understand the individual characteristics that might prevent these interventions making an impact on some people.

New research in the British Journal of Social Psychology has investigated one possible candidate – political ideology, specifically a perspective known as “social dominance orientation”. If you are invested in preserving the status quo, perhaps that encourages you to see social relations as inevitable, as “just the way things are” – an essentialist, fixed view of the world that seems to carry over to how you view human capability.

Nature vs Nurture: Mothers with multiple children have an intuitive grasp of behavioural genetics

By Christian Jarrett

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.

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.
