If you ever got picked on in the schoolyard, you might have wished for some sort of superpower: like unbeatable speed or maybe just the ability to completely disappear. Now scientists at the College of Wooster in Ohio say that you might have had a skill you didn’t realize: the uncanny ability to hear a bully 1 coming.


An earlier study found that women hear approaching noises sooner than their bigger, brawnier male counterparts. Perhaps, the scientists thought, the same would hold true for scrawny specimens 2 versus 3 the truly buff. So they had 50 volunteers listen to a tone that sounds like it’s moving toward them. The listeners pressed a button when it sounded like the tone arrived. The scientists then assessed each subject’s strength and cardiovascular fitness.


And they found that the 98-pound weaklings banged their buttons quicker than the well-muscled, because they perceived the threatening sound as being closer than it actually was. The finding got a hearing May 21st at the meeting of the Acoustical 4 Society of America in Portland, Oregon.


Such auditory overreacting, the scientists say, could be a survival mechanism 5. So that the meek 6, while waiting to inherit the earth, can avoid getting knocked onto it.


—Karen Hopkin
