Interpretation Guide
Your report contains a lot of information. This guide explains what each section means, how the scoring works, and how to turn insights into action.
All scores are expressed relative to population norms from over 22,000 test-takers. A score is not "good" or "bad" in isolation — it describes where you fall relative to others who completed the same test. Each dimension uses a six-tier system based on z-scores (standard deviations from the mean):
≥ +0.8 SD standard deviations from mean
A notably elevated tendency. For biases, this usually warrants specific attention. For strengths, this is a differentiating advantage.
+0.4 to +0.8 standard deviations from mean
Above the midpoint of the population. A meaningful tendency that shows up regularly in your decisions.
0 to +0.4 standard deviations from mean
Slightly above average. Present but not defining. May emerge under stress or in specific market conditions.
-0.4 to 0 standard deviations from mean
Slightly below average. This dimension is less prominent in your decisions than for most people.
-0.8 to -0.4 standard deviations from mean
Notably below average. For biases, this is generally protective. For personality traits, it describes the opposite tendency.
< -0.8 SD standard deviations from mean
A strongly reduced tendency. Rarely a concern for biases; for traits, the full inverse of Very High describes your experience.
The centre line matters. On the score bar charts in your report, the vertical line in the middle represents the population average. Bars extending to the right mean above-average; left means below-average. A score near the centre is not a weakness — it's stability.
The first section of your report scores you on five core personality dimensions. Unlike bias scores, personality traits are neither good nor bad — they describe your natural tendencies. Understanding them helps you design an investment approach that works with your psychology rather than against it.
High Score
Methodical, disciplined, and plan-driven. Excellent at following rules-based strategies but may struggle with necessary adaptation.
Low Score
Flexible and spontaneous. May have difficulty maintaining consistent investment habits or following trading rules.
High Score
Acutely sensitive to market stress. More likely to panic-sell during corrections but also more attuned to emotional risk signals.
Low Score
Calm under pressure. May underestimate genuine risks by being insufficiently reactive to warning signs.
High Score
Socially energised and optimistic. Good at building networks and conviction but vulnerable to trend-following and groupthink.
Low Score
Introspective and measured. Less susceptible to social influence but may miss information that circulates in networks.
High Score
Intellectually curious and open to new ideas. Great for macro investing and complex strategies, but may over-complicate.
Low Score
Concrete and practical. Performs well with tried-and-tested strategies but may be slow to adapt to changing market regimes.
High Score
Cooperative and trusting. Good at building advisor relationships but may defer too readily to consensus views.
Low Score
Independent and skeptical. Natural contrarian tendency — valuable but can produce excessive disagreement with valid evidence.
The bias section measures eleven documented financial decision-making errors. Unlike personality traits, bias scores have a directional implication: higher scores on most biases carry more risk. However, very low scores can also have downsides — being too risk-tolerant or too contrarian carries its own costs.
The ⚑ flag in your report marks biases scoring Very High, High, Low, or Very Low. These are the dimensions most likely to affect your financial outcomes and warrant active attention. Focus on no more than 2–3 at a time.
Three biases are derived from your personality scores rather than computed directly from individual questions: Over-Optimism, Emotional Vulnerability, and Immediate Gratification. They reflect how your combination of Big Five traits predicts these specific patterns.
Scores can change. Personality traits are relatively stable over years, but bias patterns can improve with awareness, practice, and deliberate rule-setting. Many experienced investors retake the test annually to track their development.
Look for the ⚑ markers in your bias report. These are the dimensions with the most potential impact on your decisions. Prioritise those that most closely match patterns you recognise in your own trading or investing history.
Each flagged section contains specific action steps. These are not generic advice — they are targeted to your score level (High vs. Low) and your variant (investor, trader, or businessperson). Read them carefully and identify one concrete change you can implement this week.
The most effective intervention for most cognitive biases is a pre-committed rule that limits the bias's influence. If you score High on Holding Losers Too Long, a hard stop-loss rule applied before entry is more effective than trying to manage the emotion in the moment.
If you work with a financial advisor, show them your report. Advisors who understand their clients' cognitive biases can structure portfolios, communications, and review processes to complement their clients' psychology rather than working against it.
Use your permanent report URL to benchmark your starting point. After a year of deliberate practice, retake the test to measure whether your flagged biases have improved. Most practitioners see meaningful changes over 1–2 years of deliberate attention.
The assessments measure your natural tendencies — not how you think you should behave, or how you perform at your best. If you answered based on aspirations rather than honest self-observation, your results will reflect that. For the most useful results, re-take the test and answer based on what you actually do, not what you wish you did.
No. Overconfidence is the single most common bias among active investors, and many highly successful investors score above average on it. The score describes a tendency, not a verdict. The recommendations in your report are designed to help you manage that tendency rather than eliminate it.
Yes. The Big Five personality traits are among the most stable individual characteristics in psychology — they typically show very little change over periods of one to three years. Significant score changes usually reflect a major life event (career change, financial crisis, retirement) rather than gradual development.
Yes. Your permanent report URL can be shared with anyone — advisors, partners, colleagues. Only you can see what test you took; the URL does not reveal your login or any personal information beyond your test results.
Very Low Emotionality describes someone who is calm, stable, and relatively unaffected by negative events. This is generally advantageous in investing — but the advice in your report to be vigilant about underestimating real risks is worth taking seriously. Stability can sometimes become complacency in genuinely dangerous market conditions.
Three bias scores — Over-Optimism, Emotional Vulnerability, and Immediate Gratification — are mathematically derived from your Big Five personality scores. This is because research shows these particular patterns are driven primarily by personality (how you are) rather than situational behavior (what you do in a given scenario). The formulas are validated from the original academic research.
