Loss Aversion and Buyer Resistance
As I learned in my behavioral economics course in undergrad, people weigh the value of a loss much more than an equivalent gain. Daniel Kahneman and Amos Tversky won the Nobel prize for their research in 2002 and coined the concept “prospect theory.” In the context of a product manager, it’s important to understand that users don’t evaluate new features objectively; they see change as a possible loss. In the reading, Gourville sums it up excellently when saying “people irrationally overvalue the benefits of something they currently possess relative to those they don’t.” When developing new interfaces, workflows, and products, PMs face immense psychological risk for their users.
The 9x Gap Between Companies and Consumers
Gourville describes what we briefly touched on in class as the “9x effect:” consumers overvalue existing products by a factor of three, while companies overvalue their innovations by a factor of three, creating a ninefold perceived gap in value. We see this just about every time Apple releases a new operating system and people wonder where, what seemed to PMs as useless features, disappeared too. Similarly, GPT5’s release was met with criticism after users no longer had the ability to choose which model to use. Even though chatGPT thought users would appreciate automatically choosing the model to run for a prompt (something 9 in 10 people probably need help choosing), people were shocked to see the option disappear. Customers always compare their new experience to what they already know, and often decide it’s not worth the switch. What feels like progress to the company oftentimes feels like disruption to the user.
How PMs Can Reduce Resistance
Understanding loss aversion changes the process of how we build and launch. The key is reducing perceived loss by making changes as seamless as possible. Gourville calls these “behaviorally compatible” innovations, or products that introduce clear benefits without forcing the user to relearn habits. For digital products this means using gradual onboarding, optional features toggles, and messaging that highlights continuity rather than change. We also need to frame adoption as avoiding a loss (“don’t miss out on XYZ”) instead of promising uncertain future gains.
