A research project called the CANDOR corpus gathered nearly 1,700 conversations between strangers with different backgrounds, finding that most people felt better after talking to someone they didn't know, despite initial expectations of a negative experience. The conversations were conducted via video calls and lasted for 30 minutes. The study suggests that talking to strangers can increase positive feelings and help build social trust. The article also explores how people's moods changed during the conversations and how they felt about each other.
