Heuristics, Less is More – Uncertainty Thinking vs. Complexity
Markowitz Used Heuristics (Not MPT) Markowitz Nobel Prize (MPT)
https://en.wikipedia.org/wiki/Modern_portfolio_theory https://www.nobelprize.org/prizes/economic-sciences/1990/press-release/http://arno.uvt.nl/show.cgi?fid=129399
Markowitz used a simple model 1/n Approach
to Investment, allocating equally to ”n”
options
Harry Markowitz is awarded the Prize Modern
portfolio theory (MPT), or mean-variance analysis,
* Need 500 years of data to prove
the model (assuming all conditions,
stocks and variables exists!
No evidence is found of the outperforming of a
model by another model. This implies that the 1/n
asset allocation strategy, often called the naïve
strategy, is not outperformed by a more sophisticated
models.

Heuristics are;
i. adaptive tools that ignore
information to make fast
and frugal decisions
ii. that are accurate and robust
under conditions of
uncertainty.
iii. considered ecologically
rational when it functionally
matches the structure of
environment.

Era of VUCA (Volatility, Uncertainty, Complexity & Ambiguity)

• VUCA is a concept that
originated with students at
the U.S. Army War College
after the Cold War.
• And now, the concept is
gaining new relevance to
characterize the current
environment and the
leadership required to
navigate it successfully.

•Tasks that map well-defined
inputs to well-defined outputs, -
e.g., labeling images of specific
animals, the probability of cancer in
medical record, the likelihood of
defaulting on a loan application;
•Large data sets exist or can be
created containing such input-
output pairs, - the bigger the
training data sets the more accurate
the learning;.
When Complex Models Work? When it’s all Static!
But we live in a world of “People’s & Behaviours”
•The capability being learned should be relatively
static, - If the function changes rapidly, retraining is
typically required, including the acquisition of new
training data; and
•No need for detailed explanation of how the
decision was made, - the methods behind a
machine learning recommendation, - subtle
adjustments to the numerical weights that interconnect
its huge number of artificial neurons, - are difficult to
explain because they’re so different from those used by
humans

• Expression of genes passed on from
generation to generation
• Different characteristics, rare or
