Mental Models for Better Decisions

To ensure decisions always match popular opinion

To simplify complex situations and reveal predictable patterns

To guarantee perfect long-term forecasting

To replace data and evidence entirely

Assuming the best-case scenario will happen

Relying solely on gut feeling without evidence

Deferring every decision to someone else

Thinking in probabilities instead of certainties

By asking how to cause failure, which reveals risks to avoid

By reversing team roles to spark creativity

By always choosing the opposite of common advice

By eliminating planning and acting immediately

Always improving forecasting accuracy

Reducing the need for evidence

Guaranteeing conservative decisions

Overestimating the rarity or predictability of events

Focusing exclusively on short-term wins

Evaluating not just immediate effects but downstream consequences

Copying last year's tactics without review

Making decisions based on intuition alone

One model always provides the definitive answer

Mental models are only useful for philosophers

They replace the need for critical thinking

They aren’t one-size-fits-all; combining models yields better judgment

Ignoring past data entirely

Waiting indefinitely for perfect information

Treating the opportunity as guaranteed success

Assigning likelihood ranges to possible outcomes and planning accordingly

Making a large irreversible change without measurement

Avoiding all experimentation to prevent mistakes

Relying on a single expert opinion forever

Testing a small change, measuring results, and iterating rapidly
