Challenges in the Health Care System
1. How to evolve an overly-constrained, mature, complex, interdependent system?
2. Institutional change is too slow– Host-pathogen systems are dynamic– Major changes in who is providing health care
– More women, alternative medicine, “Physician's will be put out of business by
nurse practitioners”
– The patient’s genomic “pre-existing condition” problem
3. Data-poor ⇒ data-rich ⇒ data-overload – c.f. “Blink” by M. McDowell
– Increasingly broad patient cultural-ethnic background
– Who is the most genetically diverse ethnic group?
“Normal” Technology Development Phases
How to organize a movement, that changes/coordinates 100s of organizations and impacts 700,000 physicians? How do you then build processes that support new “utility”? How do new structures then become “transparent” and the building blocks of new options and structures?
Extreme stages can prevent development
X XCollective reinforcement of hype can lead to a
interruption of the developmental cycle

Diversity: A Weapon of Mass Construction
Diversity 2007
Mauboussin: Deep Blue, Wisdom of the Crowds & Demise of Experts
1. Utility of experts is being eroded2. What system benefits from expert performance
– Computers: rule-based or probabilistic, limited options (low heterogeneity / complexity, but lots of data)
– Experts: rule-based, many options (moderate complexity and data)
– Collective intelligence: probabilistic, many options (high complexity, lots of data)
3. Conditions for Collective Intelligence– Diversity, an aggregation mechanism, incentives
4. Examples of Collective intelligence – Discovery: Needle in the haystack
– State prediction: Jelly beans in jar
– Future prediction: Academy Awards

Expert Performance in Finance
Why can’t financial experts outperform consistently the S&P 500
“collective” (including good + bad performers)?
• Professional money managers fail to beat the S&P 500 at an average rate of 70% per year.
• 90% trail the S&P over a 10-year period.
• Only a few beat every year for 10 years – Soros, Miller, ….
“These are the people who have more knowledge and more training than the vast majority of investors. And yet, neither the superior knowledge nor the superior experience helps them in the long run.”

Ants Solving “HARD” problems

EndIn “Learning” the maze, individuals create a diversity of experience.
A Model for Collectives Solving Hard Problems
How can groups > solve hard problems,> without coordination,> without cooperation, > without selection?
The Maze has many solutions > non-optimal and optimal.
Individuals > Solve a maze> Independently> Same capability
When individuals solve the maze again, they eliminate “extra” loops
But because a global perspective is missing, they cannot shorten their path. This is where diversity helps.

• Individuals are very sensitive to noise

Conclusions on Emergent Problem Solving
Collectives reliably solve a problem “perfectly” that experts cannot reliably solve
The emergent solution is not initially embodied in any individual (no one ant finds the shortest path).
Diverse collectives not only perform better, but they are also more robust to misinformation.
The accuracy of emergent solution correlates with diversityDiversity is defined as uniqueness of information/skills contributedDiversity of performance is also requiredCompetition, optimization or stress all reduce diversity, performance and/or
robustness.
Collective “solves” a problem that individuals are unaware of => emergent problem definition and solution
Performance from synergistic diversity has a sweet spotCollective performance is bounded by individual performance and complexity
of the problem.
