According to British psychologist Daniel Freeman, nearly one in four Londoners regularly have paranoid thoughts.

Our minds evolved to play out “danger scenarios” in order to prepare us to act in times of need. The humans who lacked this ability were eaten by saber tooth tigers long ago.
The problem is, evolution does not much penalize us for having false fears. Those with false fears become preemptively aggressive, and thus, they get the jump on the best food, water, mates, and so on.
A penalty for paranoia kicks in when groups of us realize that the individual crazy people are dangerous, however.
There is less overall penalty for false hopes. Pronoia is the false belief that people are out to help you. Either false beliefs can become a self fulfilling prophesy, so most people are too optimistic. Pronoia is why confidence scams work and why you keeping getting all that spam, by the way.
Don’t jump to conclusions. Check the evidence carefully, even when you are sure you are correct.
