The search for one of life’s greatest goals, happiness, is what brings almost 1,200 students to one of Yale University’s most popular classes ever. The class is called Psychology and the Good Life. Psychology professor Laurie Santos teaches the class. One in four Yale undergraduate students has registered to take it. It has the largest class registration size in Yale’s 317-year history. So, why do so many students want this class? Santos says it is the hope that science can help students find peace among all the stresses and difficulties they face at college. Students report being more depressed than they have ever been in history at college,” she said. Social science research has led to many new understandings of how people find happiness, Santos says. They really want to learn those insights in an empirical, science-driven way," she said of the students taking her happiness class.
