PLOS ONE: I Should but I Won’t: Why Young Children Endorse Norms of Fair Sharing but Do Not Follow Them
Children aged 7–8 years endorsed the norm of an equal split as fair, predicted that they and another child would behave in accordance with that norm, and actually did share equally with another child. Children aged 3–6 years also asserted that the resource should be divided equally, whether by themselves or by another child and they predicted that another child would adhere to that norm. Yet they predicted that they themselves would fall short of the norm, and actually did fall short. Age-related increases in inhibitory control failed to account for this closing of the judgment-behavior gap with increasing age. On the other hand, the extent to which children invoked fairness norms when reflecting on their actual sharing did explain the matching of behavior to standards that emerged among older children. The younger children focused on their own desires when explaining their predicted and actual sharing, whereas the older children talked spontaneously and explicitly about issues of fairness. The results provide some support for traditional accounts of moral development by showing that, in the course of development, children’s sharing is increasingly consistent with the norm of fairness that they endorse from an early age.

Why Can Some Kids Handle Pressure While Others Fall Apart? -
stress either causes worry or amps up performance. worriers have higher IQ, warriors test better.
SAT problem seems to be high-stakes testing.
can get better results by telling test-takers, as they start the test, that worry the night before leads to better performance.
better is to compete when there are inherent rewards for participating, practice managing stress
experience with situations helps worriers outperform warriors (eg jetpilots)

The Case for Drinking as Much Coffee as You Like - Atlantic Mobile
"There have been many metabolic studies that have shown that caffeine, in the short term, increases your blood glucose levels and increases insulin resistance," Shilpa Bhupathiraju, a research fellow at the Harvard School of Public Health's Department of Nutrition and the study's lead author, told me. But "those findings really didn't translate into an increased risk for diabetes long-term." During the over 20 years of follow-up, and controlling for all major lifestyle and dietary risk factors, coffee consumption, regardless of caffeine content, was associated with an 8 percent decrease in the risk of type 2 diabetes in women. In men, the reduction was 4 percent for regular coffee and 7 percent for decaf.

The initial impulse is still to intervene and fix the problem, or critique the actions of the teacher who
made the mistake. It also often leads students to frame their own
research around educational success stories. The idea is to pick an
intervention that promises to improve education—a new teaching
technique, curriculum approach, instructional technology, reform
effort, or administrative structure—and study it in practice. The
desired outcome is that the intervention works rather well, and
the function of the study is to document this and suggest how
the approach could be improved in the future. This often leads
to an approach to scholarship (and eventually to a kind of scholarly literature) that is relentlessly, unrealistically, sometimes
comically optimistic—one that suggests that there is an implementable answer to every educational problem and that help is always on the way

Richard Hamming: You and Your Research
Many a second-rate fellow gets caught up in some little twitting of the system, and carries it through to warfare. He expends his energy in a foolish project. Now you are going to tell me that somebody has to change the system. I agree; somebody's has to. Which do you want to be? The person who changes the system or the person who does first-class science? Which person is it that you want to be?

The importance of stupidity in scientific research -- Schwartz 121 (11): 1771 -- Journal of Cell Science
Science involves confronting our `absolute stupidity'. That kind of stupidity is an existential fact, inherent in our efforts to push our way into the unknown. Preliminary and thesis exams have the right idea when the faculty committee pushes until the student starts getting the answers wrong or gives up and says, `I don't know'.

Media Bias: Going beyond Fair and Balanced: Scientific American
Groeling’s work is one of the few studies to quantify partisan bias in the media, a subject notoriously difficult for social scientists to research and discuss. These scientists work with theories such as the socalled hostile media effect to predict that ardent supporters of a cause will view media as slanted for the other side, and they have conducted hundreds of studies that have revealed imbalances in the ways journalists frame news on topics ranging from AIDS to the war in Iraq.

Some Problems with the Notion of Context-Aware Computing, by Thomas Erickson
"The root of the problem is that the context-awareness exhibited by people is of a radically different order than that of computational systems. People notice a vast range of cues, both obvious and subtle, and interpret them in light of their previous experience to define their contexts. Thus, when at the theatre, we know when to talk, when to listen, when to clap, and when to leave. In contrast, context-aware systems detect a very small set of cues, typically quantitative variations of the few dimensions for which they have sensors."

Mind Hacks: Minds and myths
"Mary Smyth at Lancaster University ... compared psychology and biology textbooks and found that psychology appears to have comparatively few taken-for-granted facts. Instead, numerous experiments are described in detail, lending scientific credence to any factual claims being made. ... there’s that ever-present pressure to demonstrate that psychological findings are more than mere common sense. Benjamin Harris says that historians have described psychology as putting a scientific gloss on the accepted social wisdom of the day."

Moreover, the researchers found that the amount a participant cheated correlated with the extent to which they rejected free will in their survey responses."

Physiognomy | The shape of your face betrays how aggressive you are--if you're a man
In a paper just published in Proceedings of the Royal Society, two Canadian scientists have concluded that one's predisposition to aggression is signalled by the ratio of width to height of the male face, whose proportions are shaped in puberty by the (among other things) aggression-inducing testosterone. This works for men (tested in hockey players and undergraduates) but not women (undergraduates). Other findings not in this paper: women can predict a man's interest in children from his face, and both trustworthiness and dominance also show up.
