This is the reason why some people are very attracted to us and some are not at all

To understand the link between attractiveness and the understanding of feelings, 90 people watched videos of women showing sadness or fear on their faces. The participants then had to gauge this woman's feelings and and to say how confident they are in their assessment. The researchers also monitored the participants' brain activity while watching the videos. They found that the more confident a person was in the feelings of the woman in the videos, the more attracted they were to that woman. By observing brain activity, they found that when emotions are read correctly, the brain is activated reward center, which can stimulate attraction.

Mixed signals are not desirable

In other words: men should more attractive women whose feelings they can recognize or read with confidence. If the brain can process the sender's emotional signals well enough, we are rewarded and we feel attracted to that person. But if that doesn't happen, if we can't read a person's emotions, then the brain can negative "evaluation".

"Correct understanding of another person's feelings and intentions is essential for social interaction," says Silke Anders, author research and Professor of Neuroscience at the University of Lübeck. "In order to achieve common goals, partners must understand each other and constantly "upgrade" information about their current intentions and motivations, anticipate the other's emotions and adjust their behavior appropriately."
