The Click Effect — Inside the Science and Magic of Social Chemistry

January 27, 2026·54 min·5 clips

Kate Murphy reveals how our heart rates and brainwaves sync up when we truly connect with someone.

The conversation turns inward first. Instead of treating awareness like charm or social polish, the speaker points to the body's quieter signals. Heart rate matters. Someone who cannot notice their own heart rate is less likely to pick up another person's anxiety. The word for this is interoception. The speaker describes a simple practice: move through different parts of the body and notice what is there. Practical, not mystical. Better self-awareness gives a person a little more space to tell the difference between their own reaction and a state they are absorbing from someone else. Then the trading example sharpens the point. In one study, high-frequency traders at a hedge fund with stronger interoception were better traders, made more money, and stayed in the job longer. That finding lands quietly. Their edge was not louder confidence or sharper swagger. It was a better feel for danger and for what other people were doing. They could sense the drift. When others moved in a risky direction, the more internally aware traders seemed less likely to get swept along without noticing. The speaker does not oversell it. The example simply makes the heart-rate idea feel real. Awareness is not only about reading someone else's anxiety. It starts below language, in the body. The clearer someone can feel what is happening inside them, the better chance they have of noticing when they are being pulled somewhere they did not mean to go.
