FCrowdActivityCognitionTag is a type of FGameplayTag that only allows tags mapped to the "CrowdActivityCognition" base category.
Tags (or even other categories) mapped to "CrowdActivityCognition" encapsulate anything from knowledge, reasoning, to memory for crowds specifically. FCrowdActivityCognitionTag just denotes this in a more type-safe way, which is understood by the editor when used as property or function argument.
