   The Third Alternative, Made Practical
2. Reject the fixed-pie assumption
   Stop assuming your gain must be their loss — most negotiations have hidden joint gains.

3. Map interests for both sides before generating solutions
   Write down both parties’ known and inferred interests before proposing anything — the map reveals trades that no single position could.

4. Test each component probability separately
   Before judging a joint claim, estimate each element on its own, then check whether the conjunction is lower.
   The Conjunction Fallacy — When "More Details" Feels More Likely
5. Write contingent contracts when forecasts disagree
   If you and the other side have different predictions, let the outcome decide who was right.

6. Expanding the Pie: Negotiation Beyond Splitting the Difference
   Expanding the pie means trading across issues that the two parties value differently, so both sides gain more than any fixed compromise would allow. Malhotra and Bazerman’s research shows that most negotiators leave joint gains on the table because they treat every issue as a zero-sum battle.
7. Separate facts from assumptions explicitly
   Sort what you actually know from what you’re assuming, in two visible columns.
   First-Principles Thinking, Made Usable
8. Bridge disagreements with contingent terms
   When you disagree about the future, bet on it — tie terms to what actually happens.
   Win-Win Thinking: Expanding the Pie
9. Invent options for mutual gain
   Brainstorm multiple possible deals before deciding, expanding the pie before splitting it.
   Getting to Yes: Principled Negotiation
10. Recognize that random sequences don’t "owe" balance
    Random processes have no memory — a run of heads doesn’t make tails more likely.

Does this sound like the set of challenges you might be facing?

• I’m walking into this dead certain it’s one fixed pie→
• I’m walking into this thing braced for a fight, certain that whatever they get is coming straight out of my pocket→
• I’m walking into this assuming it’s a fixed pie where their win is my loss, and I’ve only ever thought through my own side→
• When two things fit together neatly in my head, I treat the whole package as more likely than either piece alone→
• We’re deadlocked because they’re certain the numbers will land one way and I’m just as certain they won’t→
