Frequency Illusion (Baader-Meinhof Phenomenon)
The Frequency Illusion (informally called the Baader-Meinhof Phenomenon) is the experience of noticing something β a new word, a concept, a car model β for the first time, then suddenly seeing it everywhere. The phenomenon has two components: selective attention (you notice it more because it's now in your awareness) and confirmation bias (you remember the occurrences you notice and forget those you don't).
