The test starts with the nature of the work. For a simple activity with a known answer, Syed argues that adding different viewpoints may not improve execution. For complex work, however, the team should map what its current members know, where their backgrounds and models overlap, and which customers, threats or contexts remain poorly understood. It then adds people or advisers whose relevant experiences produce genuinely different information, not merely different appearances. Those perspectives must be included in the actual decision process rather than condescended to or used as a symbolic appointment. The final check is practical: did the broader group generate distinct options, expose blind spots, or improve the spread and accuracy of predictions? The framework ties diversity to mission-specific problem solving.

Core principles
- 01Diversity creates value when different perspectives improve a complex task
- 02More people do not create more ideas when everyone thinks alike
- 03Relevant lived experience can reveal risks that technical credentials miss
- 04The needed variety depends on the mission rather than a universal template
How to run it
- 1
Classify the problem
Decide whether the work has a known solution or requires judgment under uncertainty. Reserve the strongest diversity case for the latter.
Pro tip Ask whether reasonable experts could reach different answers from different information.
Watch out Do not claim that every form of diversity improves every task.
- 2
Map current overlap
List the team's backgrounds, models, customer knowledge and predictions. Look for repeated assumptions disguised as independent agreement.
Pro tip Compare how members reached an answer, not only whether their answers match.
- 3
Name the blind spots
Identify environments, groups, threats or technical possibilities the current team cannot confidently interpret.
Pro tip Use past surprises and failed predictions as evidence of missing perspective.
Watch out A team may not be able to identify all of its own unknowns without outside input.
- 4
Add relevant difference
Recruit, consult, or partner with people whose knowledge addresses the named blind spots and who can offer independently formed views.
Pro tip Match the source of difference to the problem rather than applying a generic composition formula.
Watch out Visible difference does not guarantee cognitive difference, and similar appearance does not guarantee identical thinking.
- 5
Include and test
Give the new perspectives real influence, then examine whether they expose risks, create options, or improve forecasts.
Pro tip For forecasting, compare individual accuracy and the diversity of predictions before averaging them.
Watch out Hiring without inclusion leaves the original echo chamber intact.
In the wild
Syed describes a challenge posed at an HR conference: four cloned Usain Bolts would lack diversity but might form an excellent sprint relay. He accepts the logic for a simple activity where speed is the dominant known requirement, then argues that the conclusion reverses for complex problems where no one has the full answer.
→ The example establishes that the value of cognitive diversity depends on task complexity rather than a universal slogan.
Syed argues that a highly homogeneous intelligence team can hold strong academic credentials while lacking experience needed to interpret sectarianism, radicalization, or unstable political institutions. He presents the CIA and Western analysis of Iraq as cautionary examples of relevant blind spots.
→ Mission-relevant backgrounds could broaden the hypotheses considered when assessing threats in unfamiliar contexts.
Common mistakes
Using diversity as a slogan
A symbolic commitment does not explain which decisions will improve or how different knowledge will enter them.
Counting people instead of ideas
A large organization can still behave like an echo chamber when thousands of employees share the same assumptions.
Recruiting without inclusion
Different voices add little if incumbents dismiss them or exclude them from consequential discussions.
Is it for you?
Best for
Organizations solving uncertain problems across unfamiliar customers, cultures, technologies, or future scenarios.
Not ideal for
A simple standardized task where the correct method is already known and the main requirement is consistent execution.
From the transcript
“if your mission is to solve complex problems diversity is the cornerstone of how well you do it”
“you need to figure out what it is that we don't know”
