Valentine cards are filled with expressions of unequivocal adoration and appreciation. That’s fitting for the holiday set aside to express love and reaffirm commitment to one’s romantic partner.

But what if there’s more going on below the surface of these adoring declarations? How might thoughts and feelings that people are not even aware of shape their romantic relationships?

It was a chilly Saturday night in April 2016, and hundreds of Princeton University students were getting ready to party. The place: one of the university’s famous eating clubs. They double as both dining halls and social-event spaces, and more than 70 percent of Princeton’s undergraduates are members.

Outside the club, in a tent strung with Christmas lights, Ana Gantman sipped coffee, ordered pizza, and prepared for a different form of evening entertainment—a field experiment that would last until 2 a.m.

More than 33,000 people in the United States die from gun-related injuries each year, making firearms the second leading cause of injury-related death. Many of these deaths could be avoided through policy—for example, Australia all but eliminated gun deaths through a series of gun control measures that included a massive gun buyback program, an assault weapons ban, and strict gun-trafficking policies. In the U.S., the current political climate would prohibit such dramatic changes. And yet, we believe there is still room for politically viable gun legislation that will save lives.

In our first article, about behavioral science and literature, we suggested three reasons why behavioral scientists should be interested in literature. First, both authors and social scientists pursue similar questions about how and why humans think and act as they do. Second, fiction has shaped the concepts that people and societies use to understand their own behavior. Third, literature can open up a wider range of examples that illustrate core behavioral science principles.
