Familiar hosts Avaneesh, Uyen, and Cameron discuss two of Erika's recent studies. One investigates “temptation bundling,” the process of pairing a pleasurable indulgence with a less-pleasurable behavior that confers delayed rewards in order to make it seem more appealing in the short-term. A second study demonstrates the concept of “motivation laundering,” when individuals who behave in accordance with financial incentives later forgo their monetary rewards in order to signal to others (or convince themselves) they acted out of purer motives. Erika is a researcher with The Wharton School at the University of Pennsylvania.Music by Solomon Krause-Imlach.Follow us on Twitter as @usefulsci, Instagram as @usefulscience, or email us at podcast@usefulscience.org.Show NotesTeaching temptation bundling to boost exercise: A field experimentForgoing earned incentives to signal pure motives
