Substition refers to a fact that many people do not believe.

公眾不同意的真相是指很多人不相信的事實(shí)。

Substition was coined by the British novelist Terry Pratchett, who died on March 12, 2015 from Alzheimer's disease. It's the opposite of superstition1. That is, a superstition is something that isn't real, but many people believe, so a substition is something that is real, but many people do not believe.

這個(gè)詞是由英國(guó)小說(shuō)家泰瑞普萊契創(chuàng)造的（普萊契于2015年3月12日死于阿茲海默癥）。該詞是superstition（迷信）的反義詞。也就是說(shuō)，superstition是某種虛假的事物，但很多人相信，而substition則是某種真實(shí)存在的事物，但很多人卻反而不信。

Substition和substitution（代替，替換）在拼寫上極為相似，在學(xué)習(xí)和背誦時(shí)必須要注意兩者的差別。
