Last week, I wrote about the importance of practicing healthy paranoia. The definition of “paranoia” is “a tendency on the part of an individual or group toward excessive or irrational suspiciousness and distrustfulness of others.” My definition of “healthy paranoia” is “the intentional practice on the part of a person to be reasonably and rationally suspicious and distrustful of people who the person is not intimately familiar with, so the person can guard against unanticipated surprises and dangers.”
