so says this study! My question is-in your personal experience, is it true in day
to day life, be it academics, relationships or problem solving?
Would love to hear from every one.

"HOUSTON: Women all over may not like it but it has been proved that
men are smarter than women.
A study of 100,000 17- to 18-year-olds on the Scholastic Assessment
Test (SAT) published in the September 2006 issue of the journal
Intelligence, has confirmed a surprising new finding-that men have a
4 to 5-point IQ advantage over women by adulthood.
Because girls mature faster than boys, the sex difference is masked
during the school years, which explains why the sex difference was
missed for 100 years.
The new study, based upon an analysis of SAT scores that correlates
to IQ, appears to confirm the similar earlier research, using a
different methodology, that concluded adult men have IQs 3.3 to 5
points higher than women.
It also found that the g factor--the general factor of mental
ability underlay both the SAT Verbal (SAT-V) and the SAT Mathematics
(SAT-M) scales with the congruence between these components greater
than 0.90, and that it was the g factor that predicted student
grades better than the traditionally used SAT-V and SAT-M scales.
The male and the female g factors were congruent in excess of .99,
and they favoured males to an equivalent of 3.63 IQ points.
The male-female differences were present at every socioeconomic
level, and across several ethnic groups.
The average male advantage was found "throughout the entire
distribution of scores, in every level of family income, for every
level of fathers' and of mothers' education, and for each and every
one of seven ethnic groups," said J Philippe Rushton, professor of
psychology at the University of Western Ontario, one of the authors
of the study.
The paper's results dovetail with those from several other recently
published studies showing that men--surprisingly- -have a 4 to 5 IQ
point advantage over women by late adolescence and early adulthood.
Before that age the two sexes are equal in general intelligence.
As such, the findings overturn a 100 year consensus that men and
women average the same in general mental ability.
Because girls mature faster than boys, the sex difference is masked
during the school years. Since almost all the data showing an
absence of sex differences were gathered on school children, this
might explain why the sex difference was missed for so long.
For decades, however, psychologists have accepted that men and women
differ in their test "profiles," with males averaging higher on
tests of "spatial ability" and females higher on tests of "verbal
ability." These differences were assumed to average out.
The authors of the study, psychologists Douglas N Jackson and J
Philippe Rushton at the University of Western Ontario, conducted the
study because two recent sets of observations had raised anew the
question of sex differences in general intelligence.
The first was that the general factor of mental ability--g-- was
found to permeate all tests to a greater or lesser extent. Thus,
a "spatial" test may be relatively high on g (mental rotation) or
low (perceptual speed), a "verbal" test may be relatively high
(reasoning) or low (fluency), as may a "memory" test be high
(repeating a series in reverse order) or low (repeating a series in
presented order).
More than any other factor, the test's g loading best determines a
test's power to predict academic achievement, creativity, career
potential, and job performance. Hence, the question of sex
differences became formulated more precisely as: "Are there sex
differences on the g factor?"
Another set of observations concerned the sex difference found in
brain size and the relation between brain size and cognitive
ability. Studies published in 1992 at the University of Western
Ontario by zoologist C Davison Ankney, and also by psychologist
Rushton, showed men average a 100-gram advantage over women in brain
weight (and volume).
Earlier, a study of 1,261 adults, published in 1992 by zoologist C
Davison Ankney, found that men's brains were about 8 percent heavier
than those of women.
A 1997 study in Denmark documented that men have about 15 per cent
more neurons -- the functional unit of the brain -- than women.
