The Flynn Effect is somewhere in the neighborhood of 1⁄3 IQ point per year. So unless your girlfriend is 120 years younger than your grandmother…
Also the Flynn Effect is observed in similar magnitudes in men and women. IQ_you/IQ_yourgirlfriend is predicted to be the same as IQ_grandpa/IQ_grandma, at least the part of that ratio attributable to the Flynn effect.
(You should escape underscores with backslashes, or they get converted to italics; also, it makes little sense to use ratios rather than differences as the zero of the modern scale is more or less arbitrary.)

He didn’t actually mention the Flynn effect in the above post.
OK you’ve got me freaked out. I’m staring at army1987′s comment that I replied to and it says ”...contraceptives, the Flynn effect, etc.”
What am I missing?
I have no idea how I managed to miss that.
