Trust is important in everyday life, but we don't know much about how it works. A study looked at trust in natural settings using data from over 4,500 social interactions. They found that trust levels vary depending on how we see the person we trust, how close we are to them, and the situation we're in. Our general trust, moral beliefs, and how we see others' value affect how much we trust people. Trust is higher when we share more about ourselves and cooperate, especially when there's a conflict of interests. Trust is like a bridge that connects how we see others, how close we are to them, the situation we're in, and how we act.
