The fifth step in brain mastery involves focusing in on certain aspects of your body language and others’ behavior to increase your success rate as a leader and a colleague in your organization – or indeed, in your personal life. Sandy Pentland, of the MIT Media Lab, has studied what he calls “honest signals,” meaning aspects of behavior that reliably (honestly) predict how successful a particular human interaction is going to be, whether it’s speed dating, or a venture capital pitch. What he’s found is that these signals more accurately indicate the likelihood of the interaction working out well for the participants than any other method of prediction.
