The project

Find out who you are, before you beat the market.

'Neuroeconomics: Before you beat the market' is a high-school research project on how human behavior shapes investment decisions. When it comes to investing, we tend to focus on techniques and strategies. But as Benjamin Graham once said, “The investor’s chief problem—and even his worst enemy—is likely to be himself.” This project asks whether the mental shortcuts that steer our decisions cluster into recognisable profiles, and whether those profiles can be identified with a short self-report instrument.

The question

Who am I? How do behavioral biases shape my investing?

Homo economicus or "economic man"–first defined by philosopher John Stuart Mill in 1836–is a theoretical model in economics that represents an idealized human being who behaves rationally and makes decisions solely based on self-interest, without the influence of emotions or irrational impulses. But are we, really, these rational creatures? My research argues the opposite: no matter how much investing knowledge you possess, if you invest monthly into ETF's without acting out on your emotions and touching your assets, your investments will grow long-term, inconsequently of the market's daily fluctuations.

This project anayzes seven behavioral biases based on what I call the 'Seven deadly sins' from Morgan Housel's 'Psychology of Money': Greed, Envy, Ego, Overconfidence, Fear, Impatience and Narrative Fallacy. By analysing one's own biases and thus 'deadly sins', one can without a doubt improve their investing behavior and thus their long-term returns.

Hypothesis

The aim of this project is to reinforse this belief: the psychology behind one's decision prevails upon the knowledge of strategies and investment analyses.

How a type is assigned

Your two strongest biases, in order, place you.

01
You answer 56 statementsEach on a five-point scale from disagree to agree. Reverse-worded items are inverted before scoring.
02
Seven scores are producedOne per bias, normalised so they can be compared with each other and across respondents.
03
Your two most prominent biases decide your typeThe archetype defined on exactly that pair is the one you are assigned, and the order matters: highest first, second-highest after it. Where no archetype is defined on your pair, you are placed with the closest one.
04
Order separates otherwise identical pairsConfirmation over overconfidence is The Prophet; overconfidence over confirmation is The Scholar. The same two biases, ranked differently, are two different types.
05
A flat profile is a result in itselfLow across all seven is The Market Sage; moderate across all seven is The Disciplinarian. Both are judged on the shape of the whole profile, not on which two biases happen to lead.
Your data

What is collected, and what is not

Before the statements you are asked your age, sex, country, and how much investing experience you have. These make it possible to look at whether bias profiles differ across groups, so all of them, along with your consent, are required to take the assessment.

No name, email address or IP address is stored. Answers cannot be traced back to you, which also means a submitted response cannot be withdrawn afterwards.

What this cannot tell you

It is self-reportYou answer as you believe you behave. That is not always how you behave when money is actually at risk.
It is not a diagnosisNo clinical or financial claim is being made, and nothing here is investment advice.
The sample is not representativeRespondents arrive through the internet, which skews young and interested in the subject.
Types are descriptions, not cagesA type is a summary of a moment. Retake it in a year, especially after a market fall, and the profile may move.
