These are Cipolla’s five fundamental laws of stupidity:
Always and inevitably, everyone underestimates the number of stupid individuals in circulation.
The probability that a certain person (will) be stupid is independent of any other characteristic of that person.
A stupid person is a person who causes losses to another person or to a group of persons while himself deriving no gain and even possibly incurring losses.
Non-stupid people always underestimate the damaging power of stupid individuals. In particular, non-stupid people constantly forget that at all times and places, and under any circumstances, to deal and/or associate with stupid people always turns out to be a costly mistake.
A stupid person is the most dangerous type of person.
And who has time to get a PhD in climate science, geology, virology, astronomy, physics, biology, history, chemistry etc.
I am lazy, an adopt Bertrad Russell’s sceptisim framework,
If the excerpts broadly disagree, remain sceptical
If the experts broardy agree and you’re not an expert, you’re a fool to disagree.
