The central premise of Brain Sex (1992) is that
men and women are different because their brains
are different

the authors, Anne Moir Ph.D., geneticist, and
David Jessel, journalist, contend that sex-related
differences in brain structure and functioning
underlie observable differences in the aptitudes,
performance and behavior of men vs. women

the authors give many examples across the age
continuum and across abilities; vision is one example

the authors write,

Men see better than women in bright light.
Intriguing results also show that men tend to be
literally blinkered; they see in a narrow field - mild
tunnel vision - with greater concentration on depth.
They have a better sense of perspective than
women. Women, however, quite literally take in the
bigger picture. They have wider peripheral vision,
because they have more of the receptor rods and
cones in the retina, at the back of the eyeball, to
receive a wider arc of visual input.

differences between the sexes, whether real or
imagined, are always worth our while to PonderAbout

Brain Sex (1992) is food for thought.
