Partnering Leadership · 467 [Leadership Reset] How Minds Change: The Surprising Science of Belief, Persuasion, and Transformation with David McRaney

David McRaney, author of "How Minds Change," says social scientists can very easily tell who you voted for from just the car you drive, the music you choose, the food you eat, and the shows you watch.

He says researchers can set aside everything else they know about a person demographically and still get an accurate read on other choices from buying and viewing habits alone.

The reason, in his account, is belonging. People want to stay part of their us and be seen as good members, so daily likes and purchases line up with the group.

People group up around what they buy and watch, so those habits track their vote.
