The illusion of moral decline.

Anecdotal evidence indicates that people believe that morality is declining. In a series of studies using both archival and original data (n = 12,492,983), we show that people in at least 60 nations around the world believe that morality is declining, that they have believed this for at least 70 years and that they attribute this decline both to the decreasing morality of individuals as they age and to the decreasing morality of successive generations. Next, we show that people's reports of the morality of their contemporaries have not declined over time, suggesting that the perception of moral decline is an illusion.

Widespread misperceptions of long-term attitude change.

SignificancePeople change when they think others are changing, but people misperceive others' changes. These misperceptions may bedevil people's efforts to understand and change their social worlds, distort the democratic process, and turn imaginary trends into real ones. For example, participants believed that Americans increasingly want to limit immigration, which they said justifies tighter borders.

Do conversations end when people want them to?

Do conversations end when people want them to? Surprisingly, behavioral science provides no answer to this fundamental question about the most ubiquitous of all human social activities. In two studies of 932 conversations, we asked conversants to report when they had wanted a conversation to end and to estimate when their partner (who was an intimate in Study 1 and a stranger in Study 2) had wanted it to end. Results showed that conversations almost never ended when both conversants wanted them to and rarely ended when even one conversant wanted them to and that the average discrepancy between desired and actual durations was roughly half the duration of the conversation.

The many minds problem: disclosure in dyadic versus group conversation.

What causes people to disclose their preferences or withhold them? Declare their love for each other or keep it a secret? Gossip with a coworker or bite one's tongue? We argue that to understand disclosure, we need to understand a critical and often overlooked aspect of human conversation: group size. Increasing the number of people in a conversation creates systematic challenges for speakers and listeners, a phenomenon we call the many minds problem. Here, we review the substantial implications that group size is likely to have on how much people disclose, what they disclose, and how they feel about it.
