While researching the history of a word or a concept, very strange things can happen. One such effect is the Baader-Meinhof phenomenon (scientifically known as frequency bias) – one of the cognitive biases of psychology. It states that once you look into something, you become more aware of its existence, and it seems to appear more frequently in your everyday life than it did before. Another effect is that your brain starts making connections to things present and past that seem to relate in some way to the thing you’ve just researched. Other times, it seems that the thing you’re looking into has no recorded history at all–and you’re left to search the deep pockets of Reddit and chat forums for answers.
