* Voting may be just plain habit for some people, according to Wendy Wood, PhD, a social psychologist at Duke University and co-director of the Social Science Research Institute.
Also according to the website “Psychology today”, another reason for voting, offered by political scientists and lay individuals alike: is that it is a civic
