Reflection: Why Good Products Fail & How PMs Can Bridge the Gap
One of the most counterintuitive lessons from Eager Sellers and Stony Buyers is that innovation often fails not because it’s inferior, but because people irrationally prefer what they already have. John Gourville argues that innovation failure isn’t just a market problem, it’s a psychological one. His “9x Effect” explains: companies overvalue their innovations by a factor of three, while consumers overvalue existing products by the same amount. The result is a ninefold gap between what sellers think people want and what buyers actually desire. For product managers, this insight reframes innovation as not just about building the new, but about managing the human cost of change.
The Power of Loss Aversion in Buyer Resistance
Loss aversion is a major part of buyer resistance. Consumers weigh losses about three times more heavily than equivalent gains, meaning any feature that disrupts a familiar experience feels riskier than it objectively is.
A new interface, a shifted workflow, or even a re-labeled button can feel like a loss of control or comfort. As a product manager, recognizing this means realizing that “better” is not enough. Users need psychological safety. To leverage this, PMs can emphasize continuity and familiarity while introducing novelty. Toyota’s Prius succeeded because it didn’t ask drivers to abandon the combustion engine entirely, it just made sustainability feel familiar. Similarly, product managers can design onboarding flows that celebrate progress (ex. “Look how much faster this is!!”) while gently reinforcing retained benefits (“All your old configurations are still here”).
Balancing Innovation + Resistance
Balancing the desire to innovate with the need to reduce resistance requires intentional trade-offs. The product-versus-behavior matrix suggests that breakthrough products must minimize behavioral change to accelerate adoption. For instance:
- Phased rollouts, where new features are introduced gradually rather than all at once.
- Designing to be behaviorally compatible, where we preserve key user habits, such as keeping layout familiar.
- Framing benefits clearly to make perceived gains direct and immediate, not abstract.
Overall, this balance turns innovation from disruption into evolution to help users feel empowered rather than alienated.
The Trap of Feature Creep
Additionally, to reduce resistance, PMs often overcompensate by adding features, creating feature creep. Ironically, this clutters the product, confuses users, and increases resistance instead. Each added feature can represent a small behavioral tax on the user.
To avoid this, PMs must anchor feature decisions to core user value, not internal enthusiasm. Techniques like “minimum lovable product” (MLP) prioritization and user story mapping can help teams stay focused. As Gourville implies, restraint is strategic: innovation succeeds not by adding more, but by making less feel like more.
Therefore: Designing for Human Change
Ultimately, the most effective product managers are not just builders but translators between innovation and psychology. Understanding loss aversion, behavioral inertia, and feature overload transforms how we design and launch products. True innovation isn’t about how radically new a product is, but about how gracefully it helps people let go of the old.
