Problem Restatement
The initial definition of a problem often determines the direction of analysis and solution. By restating the problem, we can uncover deeper issues and avoid addressing only symptoms.

Problem Restatement and Alternative Approaches
This heuristic focuses on using everyday inconveniences or news items to generate alternative ways of stating a problem or finding different approaches to it, without necessarily solving it. The goal is to explore different perspectives on the problem situation.

Problem Reversal (Inversion)
Problem Reversal is a heuristic that involves examining a problem from its opposite perspective—asking how to cause or worsen the problem—to uncover hidden assumptions and generate creative solutions.

Problem Scoping
Problem scoping makes expert-judgment questions precise enough for respondents to interpret them consistently. Pretesting, clear terms, separate questions for separate issues, and explicit time and location boundaries help.

Problem Solving
A problem is a gap between what one has and what one wants. De Bono distinguishes problems needing information, problems needing a new arrangement of existing information, and unnoticed opportunities for improvement. He uses open-ended discussions and closed puzzles to practice different approaches.

Procedural Justice & Bargaining for Group Decisions
Bargaining can help a group consider alternatives and reach a decision its members will support. Procedural justice adds a fair process: people can state their case, the evidence is considered consistently, and the decision is explained. Both can make implementation easier without guaranteeing agreement or success.

Proceeding Despite Risk and Uncertainty
People with a cautious ('Blue') mindset perceive risks in nearly every activity, while those with a risk-tolerant ('Red') mindset downplay risks. These views span a spectrum of risk perception. Deciding to proceed requires acknowledging uncertainty.

Proof by Verbosity
Proof by verbosity uses a volume of claims, technical language, or tangled reasoning to discourage scrutiny.

Prospect Theory

Prospect Theory: Loss Aversion in Negotiation
Prospect theory (Kahneman & Tversky, 1979, 1984) explains how people make decisions under risk, particularly that losses loom larger than gains, leading to loss aversion and status quo bias. This has significant implications for negotiations and conflicts, where parties may be reluctant to accept changes that involve certain losses for uncertain gains.

Taleb uses mithridatization and hormesis as limited precursors to antifragility.
