To prevent reactive emotions and confirmation bias, adopt a strict personal rule: it is "illegal" to form an interpretation or an emotional response until you have gathered all available information. This forces a pause for critical thinking and objectivity before solidifying a perspective.

When facing ambiguity, the best strategy is not to wait for perfect information but to engage in "sense-making." This involves taking small, strategic actions, gathering data from them, and progressively building an understanding of the situation, rather than being paralyzed by analysis.
To combat self-deception, write down specific predictions about politics, the economy, or your life and review them 6-12 months later. This provides an objective measure of your judgment, forcing you to analyze where you were wrong and adjust the thought patterns that led to the incorrect forecast.
Log your major decisions and expected outcomes into an AI, but explicitly instruct it to challenge your thinking. Since most AIs are designed to be agreeable, you must prompt them to be critical. This practice helps you uncover flaws in your logic and improve your strategic choices.
Our brains are wired to find evidence that supports our existing beliefs. To counteract this dangerous bias in investing, actively search for dissenting opinions and information that challenge your thesis. A crucial question to ask is, 'What would need to happen for me to be wrong about this investment?'
To combat misinformation, present learners with two plausible-sounding pieces of information—one true, one false—and ask them to determine which is real. This method powerfully demonstrates their own fallibility and forces them to learn the cues that differentiate truth from fiction.
AI models tend to be overly optimistic. To get a balanced market analysis, explicitly instruct AI research tools like Perplexity to act as a "devil's advocate." This helps uncover risks, challenge assumptions, and makes it easier for product managers to say "no" to weak ideas quickly.
No matter how intelligent you are, personal bias clouds judgment. For all significant decisions—personal, professional, or economic—consult a trusted "kitchen cabinet" of objective advisors. This external perspective is crucial for sound decision-making and protects against isolated thinking.
To counteract the brain's tendency to preserve existing conclusions, Charles Darwin deliberately considered evidence that contradicted his hypotheses. He was most rigorous when he felt most confident in an idea—a powerful, counterintuitive method for maintaining objectivity and avoiding confirmation bias.

The brain's tendency to create stories simplifies complex information but creates a powerful confirmation bias. As illustrated by a military example where a friendly tribe was nearly bombed, leaders who get trapped in their narrative will only see evidence that confirms it, ignoring critical data to the contrary.
16th-century philosopher Montaigne collected bizarre foreign customs (e.g., blackening teeth) not for novelty, but to remind himself how arbitrary his own cultural norms were. This practice helps leaders and investors question their own deeply ingrained, "obvious" truths and see reality from a new perspective.
