I came across an interesting fact today, apparently the ratio of the second digit (index finger) to the fourth digit (ring finger) in men is is correlated with various factors related to early testosterone exposure including agression, percieved masculinity, and many other things.

So i decided to see if these results hold true for me.

I scanned my right hand (photocopying also works), then measured the legth of the two fingers in pixels in photoshop and divided length of index finger by ring finger. The results are as follows:

1054 : 1040 = 1.013

1056 : 1031 = 1.024

That is higher than the male average of 0.947 (n=136) this isn't the highest male score but
is higher than most other men. This means that i am percieved as less masculine and dominant and i am probably less likely to be agressive. I would say those results are
pretty much what i expected, i am a big girl.

can anybody else be bothered to do this (it unfortunately only works for men)?
