Recency illusion

The recency illusion is the belief or impression that a word or language usage is of recent origin when it is long-established. The term was coined by Arnold Zwicky, a linguist at Stanford University primarily interested in examples involving words, meanings, phrases, and grammatical constructions. However, use of the term is not restricted to linguistic phenomena: Zwicky has defined it simply as, "the belief that things you have noticed only recently are in fact recent".

According to Zwicky, the illusion is caused by selective attention.
