The term “Magical Thinking” is defined by the Free Online Medical Dictionary as: irrational belief that one can bring about a circumstance or event by thinking about it or wishing for it.
You can find a better definition of Magical Thinking on one of the first pages of Burrough’s book. Burroughs uses the classic childhood example of “step on a crack and break your mother’s back”.
No rational person really believes that stepping on a crack in the sidewalk will cause their mother to have back problems. But, little kids still avoid the cracks, and sometimes, this behavior continues on into adulthood.
