We may not see the connection between our mental health and our wallets, but a new study suggests that sad people make poorer financial decisions compared to their happier counterparts.
The reason, according to Jennifer Lerner of the Harvard Kennedy School of Government and colleagues Ye Li and Elke Weber of Columbia University who published their study in the Psychological Science journal last year, is that sad people exhibit what's known as "present bias," meaning they tend to value the present over the future, choosing immediate gratification and ignoring the greater gains associated with waiting.
