I didn't read the actual study, but from the article they are basing this on the amygdala size being bigger but the male brain also just overall being bigger.
My question is: What rules out the bigger size itself (irregardless of overall brain size) causing differences? Perhaps, the ratio of amygdala size to brain size does not matter but rather just the absolute size.
