We might think women are not as adept as men at wielding heavy tools, like say, hammers, according to popular stereotypes.

Scientists measured the accuracy and force of men and women’s blows to a metal plate.
Indeed they found that men struck twice as hard as the women. But women were 25 percent more accurate than men

The researchers theorize that maybe men and women inherently use different strategies, putting more emphasis on either force or accuracy, respectively. But these are preliminary results. They intend to do further studies with larger sample sizes in different conditions.

But for now that old stereotype might need to be retooled.
