Smart, well-informed teams make bad strategic calls with depressing regularity — and usually not for lack of analysis. The culprit is predictable: cognitive bias. Behavioral strategy applies what behavioral science knows about how minds actually decide, and builds decision processes that compensate for it.
The biases that wreck strategy
- Confirmation bias — seeking evidence that supports what we already believe, ignoring the rest.
- Anchoring — over-weighting the first number or idea on the table.
- Sunk-cost fallacy — throwing good money after bad because we've already invested.
- Overconfidence — systematically overestimating our forecasts and underestimating risk.
- Groupthink — the pull toward consensus that silences dissent and kills good objections.
You can't will yourself unbiased. You can design a decision process that makes bias harder to act on.
Debiasing is a process, not willpower
The insight of behavioral strategy is that individual awareness barely helps — knowing about anchoring doesn't stop you anchoring. What works is process design:
- Pre-mortems — imagine the decision failed; explain why. Surfaces risks consensus would suppress.
- Devil's advocate / red teams — assign someone to argue against, legitimising dissent.
- Reference-class forecasting — estimate from how similar past projects actually went, not from inside the rosy plan.
- Decision journals — record what you expected and why, so you can learn from outcomes instead of rewriting memory.
Why product managers especially need it
Product decisions are made under deep uncertainty, with incomplete data, by teams emotionally invested in their ideas — a perfect storm for bias. A PM who builds debiasing into roadmap and prioritisation decisions makes systematically better calls than one relying on being smart.
Decide better under uncertainty
My Behavioral Strategy course covers the biases that distort decisions and the process tools — pre-mortems, reference-class forecasting, decision journals — that beat them.

Can't you just be aware of biases?
Awareness barely helps — biases operate below conscious control. What works is designing the decision process (pre-mortems, red teams, reference classes) so bias is harder to act on.
Is this only for product managers?
No — any leader making decisions under uncertainty benefits. Product management just concentrates the conditions where bias bites hardest.
