Taking Lecture Notes On A Laptop Might Not Be That Bad After All

By Emma Young

“The pen is mightier than the keyboard”… in other words, it’s better to take lecture notes with a pen and paper rather than a laptop. That was the hugely influential conclusion of a paper published in 2014, by Pam Mueller and Daniel Oppenheimer. The work was picked up by media around the world, and has received extensive academic attention; it’s been cited more than 1,100 times and, the authors of a new paper, also in Psychological Science, point out, it often features in discussions among educators about whether or not to ban laptops from classrooms. However, when Heather Urry at Tufts University, US, and her colleagues ran a direct replication of that original study, their findings told a different story. And it’s one that the team’s additional mini meta-analysis of other directly comparable replications supported: when later quizzed on the contents of a talk, participants who’d taken notes with a pen and paper did no better than those who’d used a laptop.

Reminders Of God Don’t Actually Encourage Us To Take Risks, Replication Study Finds

 By guest blogger Sofia Deleniv

“…Do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you.”

This passage, pulled from Isaiah 41.10, is just one example of the Bible’s many references to God’s power to protect. And this protective persona might affect you much more than you think. At least that’s what emerged in 2015, when researchers from Stanford University published a string of studies finding that people prompted to think of God made significantly riskier decisions — whether or not they were religious.

The scientists’ explanation, promptly picked up by the media, was that thinking of God makes risk-taking less intimidating because it primes us to expect divine protection. As of recently, however, this narrative has not stood up to scrutiny. The first pre-registered replication of this study, published in the journal Psychological Science, suggests that the effect was probably no more than an exciting false positive.

This Hard-To-Read Font Was Designed To Boost Memory — But It Might Not Actually Work

By Emily Reynolds

Whether we’re learning a new language, prepping for a job interview or simply trying to remember what we went into the kitchen for, many of us are keen to cultivate a better memory. And often strategies that add an element of effort or difficulty can help: drawing things rather than writing them down, for example, or generating questions about study material rather than simply reading it.

So in 2018, there was much fanfare when a team from Australia’s RMIT University developed a difficult-to-read font, Sans Forgetica, that they said could boost memory through such a “desirable difficulty”.

But new research in Memory from Andrea Taylor and colleagues from the University of Warwick and the University of Waikato, New Zealand, has put the font to the test — and found little evidence that it actually improves our memory.

Researchers Once Found That People Believe In “Climate Change” More Than “Global Warming” — But Word Choice No Longer Seems To Matter

By guest blogger Jesse Singal

One of the biggest political challenges of this era is getting powerful people to take the threat of climate change seriously. The most straightforward way to do that would be with bottom-up pressure: if the people who vote demand that their leaders take assertive action against climate change, then politicians will have no choice but to do so (at least if they want to get into office, or to stay there). The major challenge to this, in turn, has been the lingering influence of climate denialism: disbelief in the reality that humans are the cause of climate change, or in the seriousness of the problem.

What can be done to combat climate denialism? Back in 2011, the researchers Jonathon P. Schuldt, Sara H. Konrath, and Norbert Schwarz published an article in Public Opinion Quarterly which suggested one possible partial remedy: framing the issue a bit differently. They found that 75.0% of Americans expressed belief in “climate change,” but only 67.7% in “global warming.” It was Republicans driving this effect: among this more politically conservative subset of Americans, the difference was 60.2% versus 44.0%.

Those findings suggested that environmental campaigns and policy initiatives might do better if they refer to “climate change” rather than “global warming”, write Alistair Raymond Bryce Soutter and René Mõttus in a new paper in the Journal of Environmental Psychology. But while some follow-up studies had been conducted on this issue, with fairly mixed results, no one had yet carried out a direct, pre-registered replication. So Soutter and Mõttus attempted to both replicate the original result and expand it to two other countries: the United Kingdom and Australia. (This gave them a total sample size of 5,717, about double that of the original study.)

Are You Addicted To Spending Time With Your Friends? Study Satirises Measures Of Social Media Addiction

By Matthew Warren

Do you often spend time with your friends in order to forget about personal problems? Do you think about your friends even when you’re not with them? Have you even gone as far as ignoring your family to spend time with your friends?

If you answered yes to these questions, you might fit the criteria for “offline friend addiction”, according to a new scale described in a preprint on PsyArxiv. Except, of course, that this notion is ridiculous. How can we be addicted to socialising, the fulfilment of one of our basic human needs?

Well, that’s pretty much the point of the new paper, written with tongue firmly in cheek. But behind it is a serious argument: although a scale for offline friend addiction is clearly absurd, there’s another, similar concept for which such scales have already been developed — social media addiction.

Conservatives Might Not Have A More Potent Fear Response Than Liberals After All

Terrifying SceneBy guest blogger Jesse Singal

If you follow mainstream science coverage, you have likely heard by now that many scientists believe that the differences between liberals and conservatives aren’t just ideological, but biological or neurological. That is, these differences are driven by deeply-seated features of our bodies and minds which exist prior to any sort of conscious evaluation of a given issue.

Lately, though, follow-up research has been poking some holes in this general theory. In November, for example, Emma Young wrote about findings which undermined past suggestions that conservatives are more readily disgusted than liberals. More broadly, as I wrote in 2018, there’s a burgeoning movement in social and political psychology to re-evaluate some of the strongest claims about liberal-conservative personality differences, with at least some evidence to suggest that the nature and magnitude of these differences has been overblown by shoddy or biased research.

Now, a new study set to appear in the Journal of Politics and available in preprint here suggests that another key claim about liberal-conservative differences may be less sturdy than it appears.

The Replication Crisis Lowers The Public’s Trust In Psychology — But Can That Trust Be Built Back Up?

Woman's Hand Placing Last Alphabet Of Word Trust

By Matthew Warren

Often when we discuss the replication crisis in psychology, the main focus is on what it means for the research community — how do research practices need to change, for instance, or which sub-disciplines are most affected? These are all important questions, of course. But there’s another that perhaps receives less attention: what do the general public think about the field of psychology when they hear that supposedly key findings are not reproducible?

So a new paper in Social Psychological and Personality Science should make for concerning reading. Across a series of studies involving a total of almost 1,400 participants, the researchers find that not only do low rates of reproducibility decrease public trust in the field, but that it may also be tricky to build that trust up again.

Want To Know Whether A Psychology Study Will Replicate? Just Ask A Bunch Of People

The Thinker by Rodin

By guest blogger Jesse Singal

As most observers of psychological science recognise, the field is in the midst of a replication crisis. Multiple high-profile efforts to replicate past findings have turned up some dismal results — in the 2015 Open Science Collaboration published in Science, for example, just 36% of the evaluated studies showed statistically significant effects the second time around. The results of Many Labs 2, published last year, weren’t quite as bad, but still pretty dismal: just 50% of studies replicated during that effort.

Some of these failed replications don’t come across as all that surprising, at least in retrospect, given the audacity of original claims. For example, a study published in Science in 2012 claimed that subjects who looked at an image of The Thinker had, on average, a 20-point lower belief in God on a 100-point scale than those who looked at a supposedly less analytical statue of a discus thrower, leading to the study’s headline finding that “Analytic Thinking Promotes Religious Disbelief.” It’s an astonishing and unlikely result given how tenaciously most people cling to (non)belief — it defies common sense to think simply looking at a statue could have such an effect. “In hindsight, our study was outright silly,” the lead author admitted to Vox after the study failed to replicate. Plenty of other psychological studies have made similarly bold claims.

In light of this, an interesting, obvious question is how much stock we should put into this sort of intuition: does it actually tell us something useful when a given psychological result seems unlikely on an intuitive level? After all, science is replete with real discoveries that seemed ridiculous at first glance.

Are Bronze Medallists Really Happier Than Silver Medallists? New Insights From The 2016 Olympics

To win a medal of any kind at the Olympic Games takes years of training, hard work and sacrifice. Standing on an Olympic podium is widely regarded as the pinnacle of an athlete’s career. Nonetheless, only one athlete can win gold, leaving the two runner-up medallists to ponder what might have been. Intriguingly a seminal study from the 1992 Olympic Games suggested that this counterfactual thinking was especially painful for silver medallists, who appeared visibly less happy than bronze medallists. The researchers speculated that this may have been because of the different counterfactual thinking they engaged in, with bronze medallists being happy that they didn’t come fourth while silver medallists felt sad that they didn’t win gold.

However, subsequent research based on the 2000 Olympic Games did not replicate this finding: this time silver medallists were found to be happier than bronze medallists. To further muddy the waters, a study from the 2004 Games was consistent with the seminal research, finding that straight after competition, gold and bronze medallists were more likely to smile than silver medallists, with these smiles being larger and more intense.

Now further insight into the psychology of coming second or third comes via Mark Allen, Sarah Knipler and Amy Chan of the University of Wollongong, who have released their findings based on the 2016 Olympic Games. These latest results, published in Journal of Sports Sciences, again challenge that initial eye-grabbing result that suggested bronze medallists are happier than silver medallists, but they support the idea that the nature of counterfactual thinking differs depending on whether athletes come second or third.

Has The Liberal Bias In Psychology Contributed To The Replication Crisis?

GettyImages-951722782.jpgBy Jesse Singal

There’s no simple explanation for why psychology has been hit so hard by the replication crisis – it’s the result of a complicated mix of professional incentives, questionable research practices, and other factors, including the sheer popularity of the sorts of sexy, counterintuitive findings that make for great TED Talk fodder.

But that might not be the entire story. Some have also posited a more sociological explanation: political bias. After all, psychology is overwhelmingly liberal. Estimates vary and depend on the methodology used to generate them, but among professional psychologists the ratio of liberals to conservatives is something like 14:1. A new PsyArXiv preprint first-authored by Diego Reinero at New York University – and involving an “adversarial collaboration” in which “ two sets of authors were simultaneously testing the same question with different theoretical commitments” – has looked for evidence to support this explanation, and found that while liberal bias per se is not associated with research replicability, highly politically biased findings of either slant (liberal or conservative) are less robust.
