In his book Big Weather, tornado chaser Mark Svenvold wrote about how contagious normalcy bias can be. He recalled how people often tried to convince him to chill out while fleeing from impending doom. He said even when tornado warnings were issued, people assumed it was someone else’s problem. Stake-holding peers, he said, would try to shame him into denial so they could remain calm. They didn’t want him deflating their attempts at feeling normal.
