They found, for some people, the sight of obesity sparked strong subconscious reactions, such as disgust.

Study uncovers how Ritalin works in brain to boost cognition, focus attention

I’ve got a lot to say today!

I want to chat about something that I’ve never noticed before, but probably should have. There’s always been a stereotype out there of programmers being nerdy, anti-social people (Q: How do you know when an engineer is outgoing? A: He looks at your shoes!). But my revelation of the week is that most programmers seem to be really insecure about their work. I mean: really, really insecure.

Keep on trucking

Because the endowment effect touches on so many areas, Dr Jones thinks it may be helpful for legislators to understand its evolutionary origins. That goods and rights such as pollution permits, radio spectrum and mobile-telephone licences do not inexorably flow towards the most efficient distribution worries the legal scholars charged with designing fair allocations. The effect also complicates the negotiation of contracts, as people demand more to give up standard provisions than they would have been willing to pay had they bargained anew.

Nor is the endowment effect alone in suggesting that Homo economicus is a rarer species than neoclassical taxonomists would like to believe. Other “irrational” phenomena include confirmation bias (searching for or interpreting information in a way that confirms one’s preconceptions), the bandwagon effect (doing things because others do them) and framing problems (when the conclusion reached depends on the way the data are presented). All in all, the rational conclusion is that humans are irrational animals.

Discussion

Procrastination is a complex psychological behavior that affects everyone to some degree or another. With some it can be a minor problem; with others it is a source of considerable stress and anxiety. Procrastination is only remotely related to time management, (procrastinators often know exactly what they should be doing, even if they cannot do it), which is why very detailed schedules usually are no help.

A psychology researcher has controversially claimed that stupidity is causally linked to how likely people are to believe in God.

University of Ulster professor Richard Lynn will draw the conclusion in new research due to be published in the journal Intelligence, the Times Higher Education Supplement reports.

Lynn and his two co-authors argue that average IQ is an excellent predictor of what proportion of the population are true believers, across 137 countries. They also cite surveys of the US Academy of Sciences and UK Royal Academy showing single-digit rates of religious belief among academics.

That professional skeptics don't believe in a creator is perhaps not all that surprising. Lynn argues, however, that it is their intelligence that directly gives rise to the boffinated classes' non-God-bothering tendencies. He said: "Why should fewer academics believe in God than the general population? I believe it is simply a matter of the IQ. Academics have higher IQs than the general population."

Lynn pointed out that most children do believe in God, but as their intelligence develops they tend to have doubts or reject religion. Similarly, as average IQ in Western societies increased through the 20th century, so did rates of atheism, he said.

The researchers' claims of a direct causal link have drawn criticism from others in intelligence research, who argue their conclusions are too simplistic. London Metropolitan University's Dr David Hardman said: "It is very difficult to conduct true experiments that would explicate a causal relationship between IQ and religious belief. Nonetheless, there is evidence from other domains that higher levels of intelligence are associated with a greater ability - or perhaps willingness - to question and overturn strongly felt intuitions."
