The ability to curb negative behaviors and promote positive ones is explored in this Sinan Aral speech.
As a member of the Information, Operations and Management Sciences division of NYU and MIT the speaker focuses on behavior and causation and uses this knowledge as the basis of his lecture. He explains that the potential exists to promote and reinforce positive actions in society when one understands what drives people to do certain things.
He argues that behavior is a contagious entity that can be spread by many factors including one's social circle and the similar external stimuli that the group is exposed to.
By understanding what types of messages are more easily spread to a large audience and what medium does so the most effectively, one can then use these methods to promote beneficial conduct such as empathy toward others or quitting smoking.
