Empirical evidence on how to interrogate: build rapport, not conflict

The Alisons, husband and wife, have done something no scholars of interrogation have been able to do before. Working in close cooperation with the police, who allowed them access to more than 1,000 hours of tapes, they have observed and analysed hundreds of real-world interviews with terrorists suspected of serious crimes. No researcher in the […]

Paltering: lying by using the truth

There are three types of lies: omission, where someone holds out on the facts; commission, where someone states facts that are untrue; and paltering, where someone uses true facts to mislead you. It’s not always easy to detect, but there are a few telltale signs. A recent study, published in the Journal of Personality and […]

Cross-Cultural Study on Recognition of Emoticon’s shows that different cultures see emojis differently

Emoticons are getting more popular as the new communication channel to express feelings in online communication. Although familiarity to emoticons depends on cultures, how exposure matters in emotion recognition from emoticon is still open. To address this issue, we conducted a cross-cultural experimental study among Cameroon and Tanzania (hunter-gatherers, swidden farmers, pastoralists, and city dwellers) […]

Flat UI Elements Attract Less Attention and Cause Uncertainty

In an eyetracking experiment comparing different clickability clues, weak and flat signifiers required more user effort than strong ones. […] We conducted a quantitative experiment using eyetracking equipment and a desktop computer. We recruited 71 general web-users to participate in the experiment. Each participant was presented with one version of the 9 sites and given […]

The open source community is nasty and that’s just the docs

The 2017 Open Source Survey was hosted on GitHub, which “collected responses from 5,500 randomly sampled respondents sourced from over 3,800 open source repositories” and then added “over 500 responses from a non-random sample of communities that work on other platforms.” The questionnaire was also made available in Traditional Chinese, Japanese, Spanish, and Russian. Interestingly, […]

New Vampire Battery Technology Draws Energy Directly From Human Body

According to a research paper published earlier this month, the supercapacitor is made up by a device called a “harvester” that operates by using the body’s heat and movements to extract electrical charges from ions found in human body fluids, such as blood, serum, or urine. As electrodes, the harvester uses a carbon nanomaterial called […]

Endurance in a pill

“It’s well known that people can improve their aerobic endurance through training,” says senior author Ronald Evans, Howard Hughes Medical Institute investigator and holder of Salk’s March of Dimes Chair in Molecular and Developmental Biology. “The question for us was: how does endurance work? And if we really understand the science, can we replace training […]

Popular belief that saturated fat clogs up arteries is a myth, experts say – let the wars begin: others disagree!

Heart experts have been criticised for claiming it is “plain wrong” to believe that saturated fat clogs up arteries. Three specialists argued that eating “real food”, taking exercise and reducing stress are better ways to stave off heart disease than cutting out dietary saturated fat. Writing in a respected journal, they maintained that inflammation is […]

Molecule kills elderly cells, reduces signs of aging in mice

Even if you aren’t elderly, your body is home to agents of senility—frail and damaged cells that age us and promote disease. Now, researchers have developed a molecule that selectively destroys these so-called senescent cells. The compound makes old mice act and appear more youthful, providing hope that it may do the same for us. […]

The Dunning-Kruger effect: why do incompetent people think they are so great? or Unskilled and unaware of it: How difficulties in recognizing one’s own incompetence lead to inflated self-assessments.

People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of […]

Don’t smile too big to be effective in online marketing ads, study funds

“We found that broad smiles lead people to be perceived as warmer but less competent,” said Jessica Li, a KU assistant professor of marketing in the School of Business. “We ask how that can influence consumer behavior and in what situations might marketers want to smile more broadly.” […] Li said broader smiles that tend […]

Does More Money Change What We Value at Work? – Glassdoor Economic Research

For employers, this research bolsters the idea that pay and benefits—while important—are only one factor when it comes to keeping employees engaged over the long term. As pay rises, compensation and benefits become less important as drivers of employee satisfaction. Instead, other workplace factors play a more important role. Regardless of income level, we find […]

People who swear are deemed more honest

In three studies, we explored the relationship between profanity and honesty. We examined profanity and honesty first with profanity behavior and lying on a scale in the lab (Study 1; N = 276), then with a linguistic analysis of real-life social interactions on Facebook (Study 2; N = 73,789), and finally with profanity and integrity […]

‘Tooth repair drug’ may replace fillings

The team at King’s College London showed that a chemical could encourage cells in the dental pulp to heal small holes in mice teeth. A biodegradable sponge was soaked in the drug and then put inside the cavity. The study, published in Scientific Reports, showed it led to “complete, effective natural repair”. […] They discovered […]

Entrepreneurial experiences ‘no better than textbooks,’ says study

The common thought that learning by experience is most effective when it comes to teaching entrepreneurship at university has been challenged in a new study. An analysis of more than 500 graduates found no significant difference between business schools that offered traditional courses and those that emphasise a ‘learning-by-doing’ approach to entrepreneurship education. The research […]

CRISPR gene-editing tested in a person for the first time

A Chinese group has become the first to inject a person with cells that contain genes edited using the revolutionary CRISPR–Cas9 technique. On 28 October, a team led by oncologist Lu You at Sichuan University in Chengdu delivered the modified cells into a patient with aggressive lung cancer as part of a clinical trial at […]

“You’re all going to die”: A scientifically proven pep-talk for winning

For the study, Greenberg and colleagues first recruited basketball players to play two back-to-back, one-on-one games with lead researcher Colin Zestcott, another psychologist at the University of Arizona. (The players didn’t know that Zestcott was a researcher; they thought he was another study participant.) After the first game, half of the participants were randomly assigned […]

Sexual Activity before Sports Competition: you can after all

Sexual activity before competition has been considered as a possible cause for reduced performance since ancient Greece and Rome. Recently, the hypothesis that optimal sport performance could be influenced by a variety of factors including sexual activity before competition has been investigated. However, few scientific data are available, with the exception of anecdotal reports of […]

It turns out that anonymity decreases online posting agression!

This article introduces social norm theory to understand online aggression in a social-political online setting, challenging the popular assumption that online anonymity is one of the principle factors that promotes aggression. We underpin this social norm view by analyzing a major social media platform concerned with public affairs over a period of three years entailing […]

Dutch Olympians not allowed to drink? Are they reformed religious fanatics?

Yuri van Gelder, Dutch gymnast, went out for a few to celebrate making the final. Apparently he got carried away and had some alcohol (shock! horror!) and came home at some time in the morning. So the Dutch team have sent him home, without allowing him to participate in the final. His behaviour sounds slightly […]

Meat Eaters mapped

When the world’s population passed seven billion people in 2011 we humans weighed, in total, 350 million tonnes. That weight is rising rapidly as our numbers are still growing and we are getting heavier. Back in 2011 each of us weighed, on average, just under eight stone. Around two billion of us were children then, […]

Square pie charts read best

In comparing how well people read a square pie chart, a circular pie chart, a donut shaped pie chart or a bar chart, it turns out that people do worst on the bar and best on the square pie charts. Source: A Reanalysis of A Study About (Square) Pie Charts from 2009 – eagereyes
