There is a projection effect in psychology: if a person sees everyone as a fool, suspects everyone has a conspiracy, or thinks everyone is pretending, it doesn't mean they are very smart. It usually indicates that their inner world is filled with scheming, hypocrisy, and foolishness. Because our brains can only understand things within our own cognition, a kind-hearted person finds it difficult to interpret others' behaviors as malicious at first glance. Observe others as you would yourself; cultivating the mind is fundamental.
