Are Girls' Brains Different from Boys'?
Research on gender difference must have enough courage to ask important questions but be thoughtful enough not to jump to conclusions. Here are some guidelines for reading research.
What's the Latest Development?
At this week's annual meeting of the Society for Neuroscience, panelists were quick to recognize that sex-difference research is easily abused and can justify sexism. That drew a sharp question from two female researchers in the audience who expressed concern that political correctness too often prevents researchers from asking purely scientific questions. If a few guidelines are kept in mind while pursuing research, sexism can be easily avoided.
What's the Big Idea?
Given the complexity of the brain, any neuroscience explanation that relies on a single factor is probably misleading, says Melissa Hines, a psychologist at the U of Cambridge. Genetics matter but so does socialization. And socialization can matter a great deal in experiments themselves: Women have been found to perform worse on cognitive exams when they are told men are better at it. Given how rapidly our understanding of the brain has advanced in the last decade, we must be cautious when drawing social conclusions from purely physical data.

She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.

It's one factor that can help explain the religiosity gap.
- Sociologists have long observed a gap between the religiosity of men and women.
- A recent study used data from several national surveys to compare religiosity, risk-taking preferences and demographic information among more than 20,000 American adolescents.
- The results suggest that risk-taking preferences might partly explain the gender differences in religiosity.
