You know contempt when you see it (usually) and you know contempt when you feel it (almost always). But what does contempt look like according to researchers? They call it “an emotional reaction when a person or a group violates one’s standards and one looks down on them with the tendency to distance and/or derogate […]

Typical looking faces are not the most attractive in the view of others but they are the most trustworthy. This reminds us of the post we wrote a while back about how to appear intelligent, trustworthy and attractive when you need corrective lenses (i.e., wear rimless glasses). In this case, (published in the journal Psychological […]

A new mechanism that affects how our immune cells perform - and hence their ability to prevent disease - has been discovered by an international team of researchers. To date, researchers have identified hundreds of genetic variants that increase or decrease the risk of developing diseases from cancer and diabetes to tuberculosis and mental health disorders.

It's not been a good month for the theory of ego-depletion - the idea that self-control is a limited resource that can be depleted by overuse. Two weeks ago, researchers reported evidence of bias in the published literature examinig the question of whether glucose can reverse ego-depletion.
Now, the very existence of the ego-depletion phenomenon has been questioned by an international collaboration of psychologists who conducted a preregistered replication attempt (RRR). The results have just... Read more »
