Mothers were shown an adjustable sloping walkway, and asked to estimate the steepness of slope their crawling eleven-month-old child could manage and would attempt. Girls and boys differed in neither crawling ability nor risk taking when it came to testing them on the walkway. But mothers underestimated girls and over-estimated boys – both in crawling ability and crawling attempts – meaning that in the real world they might often wrongly think their daughters incapable of performing or attempting some motor feats, and equally erroneously think their sons capable of others.
Depressing.
