So many factors influence our behavior. In fact, it is not possible to be aware of all of the factors that influence how we treat each other. New research shows how temperature has an impact on how cooperative we are. People, who were holding a warm object in their hands, were more likely to act cooperatively, than people, who were holding a cold object.
Human behavior is complicated. The more we can identify the factors that influence our actions, the more we can use that knowledge to create beneficial outcomes. So, the next time you want someone to act in a cooperative way, offer them a cup of tea or coffee. It just might make them more willing to help you out.
