The survival of the human race?

According to Simon Sinek, the very survival of the human race depends on our ability to surround ourselves with people who believe what we believe. He argues that we tend to trust people who we know share (some of) our values and beliefs more than people that are ‘merely’ reliable. Believe it or not, but when we are surrounded by people who believe what we believe, we are more confident to take risks, to experiment, and to explore, simply because we trust that people with common values and beliefs will watch our backs and help us when needed.
