Human inability to differentiate anecdotes from probabilities
Humans evolved in small communities of a hundred or so individuals. If you live in a community that size and a bear eats someone, it makes sense to take measures to avoid bears.
But if you live in a community of 300 million people (the United States) or 7 billion people (the world) and a bear eats someone (even if it is on live television), it makes little sense to change your life at all.
People simply cannot understand this at a gut level. Numbers like 300 million or 7 billion are just too large for human beings to really understand. Faced with such numbers, human probabilistic reasoning derives more from anecdotes than statistics.
Statistically speaking, because I am at greater risk from traffic accidents than from URROR
