The Baader-Meinhof phenomenon, also known as the frequency illusion, is a psychological phenomenon in which people experience a sudden and seemingly inexplicable increase in the frequency of a particular word, phrase, or idea. This can happen when someone has recently learned about a new word or concept, and they start to see it everywhere. For example, if you recently learned about a new type of bird and then started seeing that bird all over the place, you may be experiencing the Baader-Meinhof phenomenon. This phenomenon is thought to be caused by a combination of confirmation bias, selective attention, and the human tendency to find patterns in random information.
