There's an established psychological effect called "verbal overshadowing."

For example, if you ask people to think of adjectives to describe a wine they just tasted, they'll have a harder time picking that same wine out of a lineup later.

Same thing happens with eyewitness reports and identifying a suspect out of a lineup.

There's a difference between concepts and percepts.

The concepts are more abstract and must be abducted out of your percepts.

Doing the work to abduct the concepts overshadows the percepts.
