Three validated research traditions

I — Personality

Big Five Model

The Five Factor Model (OCEAN) is the most replicated personality framework in psychology — validated across 40+ years, cultures, and age groups. It consistently predicts financial decision-making behaviour.

II — Bias

Behavioral Economics

Kahneman & Tversky's Prospect Theory, Shefrin & Statman's disposition effect, and Odean's trading research underpin the 11 cognitive bias scores. Each has documented, replicable effects on real portfolios.

III — Norms

Population Data

Scores compared against norms from 22,000+ test-takers across multiple market cycles — the 2008 crisis, 2013–21 bull market, and 2020 pandemic. Z-scores show where you stand relative to real market participants.

Methodology & Foundations

Grounded in Peer-Reviewed Research

Our assessments are grounded in decades of peer-reviewed research in neuroeconomics and behavioral finance. The methodology draws from two foundational texts:

  • MarketPsych: How to Manage Fear and Build Your Investor Identity (Wiley, 2010)
  • Inside the Investor's Brain: The Power of Mind Over Money (Wiley, 2007)

The personality assessments and bias frameworks were developed through clinical psychiatry practice, Stanford postdoctoral neuroeconomics research, and investor coaching — then validated across 22,000+ investor profiles spanning multiple market cycles.

The research has been cited in academic journals and referenced in the Wall Street Journal and Financial Times.
