Think boys are smarter? Think again. 

A Canadian study, which examined data from 1914 to 2011, found that girls do better in school than boys – and have been for nearly a century.

The research found that girls perform better than boys in every grade ...  in all subjects ... all over the world.

"The fact that females generally perform better than their male counterparts throughout what is essentially mandatory schooling in most countries seems to be a well-kept secret, considering how little attention it has received as a global phenomenon," said co-author Susan Voyer of the University of New Brunswick. (Daily Mail)
