Men found it twice as hard to guess a woman’s mood than a man’s after being shown pictures of people’s eyes and estimating how they were feeling, researchers found.

When looking at male eyes, men related what they saw to themselves, with the parts of their brains linked to past thoughts and feelings lighting up, the Daily Mail reported.

However, the study showed that it is not because of men’s lack of trying – the male volunteers were given brain scans while they looked at the pictures, and the data suggested an unusual reason for the difficulty in reading women’s feelings.
