Once you adopt a new view of the world (or any part of it), you immediately lose much of your ability to recall what you used to believe before your mind changed.

Hidden costs

The social norm against stereotyping, including the opposition to profiling, has been highly beneficial in creating a more civilized and more equal society.

It is useful to remember, however, that neglecting valid stereotypes inevitably results in suboptimal judgments. Resistance to stereotyping is a laudable moral position, but the simplistic idea that the resistance is costless is wrong.

Test of understanding

Perhaps the most interesting finding of this paradoxical research is that the paradox is not always found: people sometimes go by content rather than by ease of retrieval.

The proof that you truly understand a pattern of behavior is that you know how to reverse it.
