Men vs women - level 2
A study carried out at Washington State University asked men and women to take a maths test. Both groups then guessed their results.
It turns out that the men overestimated themselves. The women, however, guessed with a lot more precision on how well they did.
Experts only asked 122 people to take the test, but the experts say that the study may also show the need for positive illusions.
Difficult words: study noun (a scientific research), overestimate (if you overestimate somebody, you think that he or she is better than he or she really is), precision(the quality of being exact or correct).
