Social trust is important for societies to function well. A study in Nigeria looked at how trust is influenced by religion and ethnicity. They found that people trust others more if they are part of the same group, like religion or ethnicity. This can affect how people interact with each other. The study used surveys from 2012 and found that group affiliation and cultural characteristics play a role in how much people trust each other. Trust is important for societies to work properly, but trusting the wrong people can lead to problems like fraud.
