10 Rules That Govern Groups « PsyBlog

  • 2. Initiation rites improve group evaluations


    Existing groups don't let others join for free: the cost is sometimes monetary, sometimes intellectual, sometimes physical—but usually there is an initiation rite, even if it's well disguised.


    Aronson and Mills (1959) tested the effect of initiation rites by making one group of women read passages from sexually explicit novels. Afterwards they rated the group they had joined much more positively than those who hadn't had to undergo the humiliating initiation. So, not only do groups want to test you, but they want you to value your membership.

  • Group norms are extremely pervasive: this becomes all the more obvious when we start breaking them.

Raising IQ: Nicholas Kristof Meets Richard Nisbett « Neuroanthropology

  • Nicholas Kristof has an op-ed today, How to Raise Our I.Q. He opens with a standard version of the individual meritocracy argument, that IQ is largely inherited:


    Poor people have I.Q.’s significantly lower than those of rich people, and the awkward conventional wisdom has been that this is in large part a function of genetics. After all, a series of studies seemed to indicate that I.Q. is largely inherited. Identical twins raised apart, for example, have I.Q.’s that are remarkably similar. They are even closer on average than those of fraternal twins who grow up together.


    If intelligence were deeply encoded in our genes, that would lead to the depressing conclusion that neither schooling nor antipoverty programs can accomplish much. Yet while this view of I.Q. as overwhelmingly inherited has been widely held, the evidence is growing that it is, at a practical level, profoundly wrong.

  • “Shared environmental influences were stronger for adolescents from poorer homes, while genetic influences were stronger for adolescents from more affluent homes.”

Bringing up baby bilingually | Twice blessed | The Economist

  • WHETHER to teach young children a second language is disputed among teachers, researchers and pushy parents. On the one hand, acquiring a new tongue is said to be far easier when young. On the other, teachers complain that children whose parents speak a language at home that is different from the one used in the classroom sometimes struggle in their lessons and are slower to reach linguistic milestones.
  • A study just published in the Proceedings of the National Academy of Sciences may help resolve this question by getting to the nub of what is going on in a bilingual child’s brain

Welcome to Your Quarterlife Crisis - EYE WEEKLY

  • They can’t make any decisions, because they don’t know what they want, and they don’t know what they want because they don’t know who they are, and they don’t know who they are because they’re allowed to be anyone they want.
