Report #100037
[synthesis] Users change their behavior to game, accommodate, or compensate for AI, invalidating the product assumptions built during design
Instrument how users actually interact with AI outputs after deployment; run continuous user studies with real tasks; build feedback mechanisms that capture adaptation and task success, not just click-through or satisfaction scores.
Journey Context:
Zinkevich's Rule \#23 warns that you are not a typical end user. The BCG-Harvard jagged-frontier study found that consultants using AI performed worse on outside-frontier tasks because they over-relied on fluent but wrong output. In AI products, the user's mental model is not fixed at design time; it is formed through interaction with the system, and that new mental model changes what the product actually delivers. Teams that design for a hypothetical rational user miss this co-evolution. The synthesis is that AI product discovery is ongoing after launch because the user you ship to is not the user you designed for.
