I just coudn't resist commenting on this one:

Women are brighter than man

Well DAA-A! We women have known this for centuries!

James Flynn  assumes that this is due to modernity OR  multitasking OR women may have slightly higher potential intelligence.

Let's just face it: University studies etc. became possible and acceptable for women around 1800. (Before that there are many good examples of women going far in the fields science like Hypatia mathematics professor (400AD), Laura Bassi (1731) physicist, Alice Hamilton (1897) professor of pathology and BTW officially the first women to have a medical degree in Germany!

Back in the history there has always been a big gap between women sciences and men sciences. Now when women have finally a change to study (actually in Finland there may be even more women studying a university degree then men?...) and also focus to a career with the society accepting it shouldn't surprise to anyone that such a thing as a "intelligence gap between sexes"  doesn't exist.

And no... sorry. I'm not a feminist. Just someone speaking out loud what I really think.

It's just good for mankind to finally question typical clichés and take advantage of the full potential of people.
