Huh. I wonder if this is at least somewhat down to sex-linked biology.
I'm trans, and my sense of smell changed significantly with hormone therapy.
Interesting. That's one way of checking for biological differences between sexes that doesn't rely on speculation or statistics (which might be confounded by self-fulfilling prophecies about gender roles).
I'd guess it's of limited utility -- there's very little good information about all of the effects of this sort of HRT (a very common conversation among trans folks is what effects the doctors never mentioned).
A lot of human sex variation is down to your hormones, particularly during puberty -- the x-vs-y chromosomes control much less than you think (the phenotypical development of the penis/testes combo is controlled by the SRY gene; sometimes you get phenotypically "male" folks with an XX pair where the SRY gene has translocated, or XY phenoty...
Information that surprises you is interesting as it exposes where you have been miscalibrated, and allows you to correct for that.
I suspect the users of LessWrong have fairly similar beliefs, so it is probable that information that has surprised you would surprise others here, so it would be useful for them if you shared them.
Example: In a discussion with a friend recently I realised I had massively miscalibrated on the percentage of the UK population who shared my beliefs on certain subjects, in general the population was far more conservative than I had expected.
In retrospect I was assuming my own personal experience was more representative than it was, even when attempting to correct for that.
