Decades of research reveals very little difference between male and female brains
  • Analysing data from three decades worth of MRI scans and postmortem brain tissue studies, scientists find no repeatable differences between male and female brains.
  • The average male has a 11% larger brain, but that doesn’t mean their brains work any better - only that the average male is bigger than the average female.
  • That’s pretty much the only reliable difference, as the sample size keeps growing bigger, any other differences prove to be statistically unreliable.
  • What this means is that we don’t have male or female brains, we just have brains - just like we have the same lungs, kidneys, or hearts.
  • The researchers didn’t look into biochemical / hormonal differences, which are speculated to be the cause of behavioral sex differences.
