Construct a research team around cognitive and professional diversity rather than conventional résumé variety alone. Combine long-only investors with people experienced in short selling, credit, forensic accounting, and investigative journalism so each can examine a company through a different failure lens. Require more than one independent reviewer for every proposed or existing position and explicitly develop both bull and bear cases. Give designated internal critics permission to search for governance, regulatory, accounting, and grassroots problems that committed analysts may overlook. The objective is not consensus or prediction of the best stock; it is reducing the probability of a blowup. Team composition should evolve as mistakes reveal missing capabilities, with new hires chosen to offset the leader's and team's demonstrated weaknesses.

How to run it
- 1
Map the Team's Blind Spots
Review past mistakes and identify which analytical perspectives or professional capabilities were missing.
Pro tip Translate each recurring failure into a specific hiring or review requirement.
Watch out Generic calls for diversity will not correct a clearly defined analytical weakness.
- 2
Recruit Contrasting Specialists
Add people trained to notice different failure modes, such as short sellers, credit analysts, forensic accountants, and investigative journalists.
Pro tip Favor candidates who can challenge the dominant investing style constructively.
Watch out Hiring only people who share the portfolio manager's background reinforces groupthink.
- 3
Assign Independent Reviews
Have multiple people inspect every prospective position without relying solely on the sponsoring analyst's work.
Pro tip Separate accounting, governance, and operating reviews where practical.
Watch out A second reviewer who merely validates the first provides little protection.
- 4
Build Bull and Bear Cases
Document the strongest evidence for owning the company and the strongest case against it.
Pro tip Let team members with shorting experience lead the bear case.
Watch out Do not treat dissent as disloyalty or poor teamwork.
- 5
Deploy Internal Critics
Give an independent group responsibility for finding faults in current holdings, including governance and regulatory risks.
Pro tip Review existing winners as aggressively as new ideas.
Watch out Attachment tends to increase after a position has performed well.
- 6
Act on the Criticism
Change position size, conduct further research, or exit when criticism exposes a material weakness.
Pro tip Track whether internal challenges actually affect portfolio decisions.
Watch out A devil's-advocacy ritual is useless if the final decision never changes.
In the wild
A traditional equity analyst favors a fast-growing company based on reported margins and market share. A forensic accountant flags aggressive revenue recognition, while an investigative researcher identifies unresolved regulatory complaints. The team reduces the position and investigates before the concerns become widely reported.
→ Independent criticism exposes correlated risks before the market reprices the company.
Common mistakes
Hiring Different Faces With Identical Thinking
Demographic variety alone does not guarantee that team members use distinct analytical methods or challenge shared assumptions.
Punishing the Bear Case
Analysts will stop raising uncomfortable evidence if dissent harms their standing inside the team.
Confusing Stability With Strength
A team with no turnover or intellectual renewal can become increasingly vulnerable to groupthink.
Is it for you?
Best for
It is best for investment firms and other high-stakes decision teams where unnoticed errors can become expensive.
Not ideal for
It is not ideal for trivial or fully reversible decisions where extensive adversarial review would cost more than the mistake.
From the transcript
“You want to have a true devil's advocacy, right um.”
“They're basically there to find faults with our existing names. So what I call them internal critics.”
“I would rather have internal debate and discussion rather than the markets criticizing you.”
