Key takeaways — Decisive
- ✓ Always generate at least three options — when leadership teams catch themselves debating only "yes or no," they have already lost the most important part of the decision.
- ✓ Run premortems before major commitments: imagine the decision has failed in two years and work backward to identify what would have caused it.
- ✓ Set tripwires in advance — predefined signals that trigger a forced re-evaluation, protecting you from the slow drift of sunk-cost thinking.
Key takeaways — Misbehaving
- ✓ Design pricing and incentives around loss aversion — people will work roughly twice as hard to avoid a loss as to capture an equivalent gain.
- ✓ Use default options as your most powerful behavioral lever; whatever you set as the default will dominate, regardless of how trivial it seems.
- ✓ Recognize mental accounting in your customers and employees — money is not fungible in their minds, and your offer architecture should reflect that.
