Can someone tell me where this breaks down?

1. Testosterone and estrogen have an influence on mental characteristics like disposition, interests, and motivations.

2. Male and female bodied people have on average significantly different levels of testosterone and estrogen.

3. Therefore, male and female bodied people will on average have differences in mental characteristics like disposition, interests, and motivations.

I understand that 3 does not follow from 1 and 2, but have not been able to figure out the reason why.
