There was an anecdote from one of Czech researches in Papua-New Guinea who said he was surprised that local hunters absolutely refused to sleep under suspicious, not entirely healthy trees, and were very careful about examining the spot before they chose it for rest. He considered the chance of the trees falling down very low, perhaps less than one in thousand.

He changed his attitude when the elders explained to him that while the chance was very low, the hunters took a lot of naps in the forest throughout their lives and over decades, the low chance translated to almost-certainty.
