The check condenses more than two hundred documented psychological biases into four practical categories: ego, emotion, attention, and conservatism. Ego includes overconfidence about skill, luck, knowledge, or foresight. Emotion occurs when visceral reactions displace analytical judgment. Attention causes people to mistake vivid or heavily covered events for likely events. Conservatism includes risk aversion, status quo bias, provincial thinking, and the assumption that familiar options are superior. Before a financial action, the decision-maker screens the reasoning against all four categories, records any detected distortion, and introduces a corrective step such as gathering base-rate data, delaying action, comparing unfamiliar alternatives, or seeking contrary evidence. The result is a more deliberate and less psychologically reactive decision process.
Origin
Daniel Crosby developed this four-part grouping while researching which of the many documented psychological biases matter most for money decisions. Extracted from Masters in Business.
Core principles
- 01A small set of meta-biases captures many financial errors
- 02Confidence must be separated from competence
- 03Emotional intensity is not evidence
- 04Media prominence is not probability
- 05Familiarity does not guarantee quality
How to run it
- 1
State the decision and evidence
Write down the proposed action, expected outcome, and evidence supporting it. Separate observed facts from forecasts and assumptions.
Pro tip Record your confidence level before running the bias checks.
Watch out An undocumented intuition is difficult to audit for bias.
- 2
Check ego and emotion
Ask whether you are overestimating your skill or knowledge and whether fear, excitement, envy, or pride is steering the choice. Reduce confidence or delay action when either is present.
Pro tip Imagine explaining the decision to a neutral adviser using only verifiable evidence.
Watch out Strong conviction can arise from emotional intensity rather than superior information.
- 3
Check attention
Determine whether recent headlines or vivid stories are making an outcome feel more probable than the data suggests. Seek historical frequencies or other base-rate evidence.
Pro tip Compare media coverage with the event's measured prevalence or probability.
Watch out Loud events are not necessarily likely events.
- 4
Check conservatism
Identify whether familiarity, the default, or fear of change is being mistaken for safety or quality. Compare at least one credible alternative on the same criteria.
Pro tip Ask what you would choose if neither option were already familiar.
Watch out Novelty is not automatically better; the goal is fair comparison rather than reflexive change.
- 5
Revise and record
Adjust the action, timing, or confidence level based on the detected biases. Preserve the record so the reasoning can be reviewed against the eventual outcome.
Pro tip Review repeated decisions to discover your dominant bias category.
Watch out Do not treat the checklist as proof that a decision will succeed.
In the wild
An investor wants to sell after days of alarming market coverage. The check reveals emotion through fear, attention through repeated headlines, ego through certainty about the near-term future, and conservatism through a desire to retreat entirely to familiar cash. She compares the headlines with long-term market data and reviews the decision with an adviser before changing anything.
→ The investor avoids an impulsive allocation change unsupported by her long-term plan.
Common mistakes
Using labels without corrections
Naming a bias has little value unless it triggers a concrete response such as delay, comparison, or additional evidence gathering.
Calling every risk emotional
Some concerns are supported by evidence; the check should improve analysis rather than dismiss legitimate risks.
Confusing familiarity with safety
Known assets and default choices can still be unsuitable or risky.
Is it for you?
Best for
It is best for investors and advisers reviewing consequential choices under uncertainty.
Not ideal for
It is not designed to calculate asset values, portfolio weights, or personalized risk capacity.
From the transcript
“Ego is the different flavors of over confidence, thinking we're better than we are, luckier, better, smarter, more knowledgeable about the future.”
“It's confusing things that are loud in the media with things that are likely or high probability.”
“we confuse things that we know with things that are good”
