Study Notes

Standards of Proof and Evidence

Models are inherently flawed, and standards of proof vary depending on the model's importance.
Importance of a model dictates your acceptable standard of proof.
Personal examples: A low standard for a model of apple pie construction, but a high standard for investment models.

Critique of Mountain Charts

Mountain charts, plots of investment historical data, are not evidence.
They are misleading visual representations highlighting trends and averages.
Instead of charts, seek actual investment prices.
Individual transactions represent true events; averages and projections do not.
Actual prices represent factual data; calculated averages and trends are opinion-based and potentially misleading.

Scientific Standards of Evidence

"Hard sciences" (physics, chemistry, biology) use reproducibility as a standard for evidence.
Experiments repeated by numerous researchers validate findings.
"Soft sciences" (economics, psychology, sociology) face greater difficulties achieving widespread reproducibility due to experimental constraints.
The cold fusion experiment highlights the importance of reproducibility, as it lacked replication.

Importance of Evidence in Financial Matters

High standards of proof are crucial in investment decisions.
The world is full of individuals aiming to convince you to invest.
Demand evidence in any matter concerning investments.
Question sources, reliability, and sources' potential motivations.

Demand for Evidence from Experts

Experts are not trustworthy automatically. Beware of hidden agendas and motivations.
Even seemingly unbiased experts might have personal gains if you invest based on their recommendations.
A fundamental question to ask is: "If they are so smart, why aren't they rich?"
Continually seek evidence and question its validity before acting on advice, especially in financial matters.

Cautionary Note on Low Standards of Proof

Individuals with low evidence standards are more susceptible to financial losses.
Low standards of evidence lead to gambling-like risk-taking.
The wealthiest individuals are often the ones who demand robust evidence.
