Heart-Synced Mutual Attraction: 2022 Ig Informal Lecture

The Ig Nobel Prizes honor achievements that make people LAUGH, then THINK.

In the Ig Informal Lectures, some days after the ceremony, the new Ig Nobel Prize winners attempt to explain what they did, and why they did it. We are releasing these lectures one at a time.

The 2022 Ig Nobel Prize for Applied Cardiology was awarded to Eliska Prochazkova, Elio Sjak-Shie, Friederike Behrens, Daniel Lindh, and Mariska Kret, for seeking and finding evidence that when new romantic partners meet for the first time, and feel attracted to each other, their heart rates synchronize.
