Frequency illusionvsRecency illusion

The short answer

Zwicky coined both, and they're easy to confuse. Frequency illusion is thinking a thing is suddenly everywhere. Recency illusion is thinking a thing is brand new — assuming a usage you only just noticed must have been invented last year, when it may be centuries old.
