The Fascinating Science Behind 'Talking' With Your Hands

Hand gestures while talking are a powerful aspect of communication.

A study analyzing TED Talks found viral speakers used nearly twice as many hand gestures as the least popular speakers. People who "talk" with their hands tend to be seen as warm, agreeable and energetic. The less animated are viewed as logical, cold and analytical.

We collect information from others' body language. We naturally feel that passionate people will be more animated and look more enthusiastic. When their gestures are bigger, we process that they must be really passionate about their topic.

This is mostly because body language is vital in helping to communicate our emotions and motivations.
