Condorcet Jury Theorem

It feels odd to have to make these arguments for diversity, again, some centuries after the Enlightenment. And centuries after Darwin, in whose name many fallacious opposite “interpretations” are levied. But apparently we must say it: diversity is good, actually.

The evidence is there for us as it has always been. Diversity isn’t a bad thing — it’s almost universally a good thing. For populations, for economies, for problem solving — for all of us. The more options there are, the higher probability that one of them might be the right match, or the thing that solves the problem, or the best selection for the job at hand.

In economics, Modern Portfolio Theory is based on the formal proof that diverse portfolios are stronger and more resilient to risk without sacrificing returns. So there’s a strict mathematical component to the arguments for diversity, but beyond that many other fields have also weighed in on the utility and pragmatic value of diversity. This assortment is a work in progress I’ll continue to add to over time:

a diverse menagerie of animals
  • In biology, more diverse populations are more responsive and resilient to a wider variety of changes. This resilience is one of the best arguments for diversity of all.
  • The best investment portfolio is the one that is most diversified. Harry Markowitz developed a mathematical proof to discover this now near-universal paradigmatic approach (MPT) in the 1950s.
  • In business, a diversity of new ideas leads to better decision-making and increased innovation; studies show a diverse workforce, as well as a diverse board, nets better results and outperforms their more conformist cousins. Conversely, too much groupthink and stale ideas lead to worse outcomes and less resilient firms.
  • Cross-pollination is generative, and the blending of ideas creates new concepts, new opportunities, new industries, and new trends — to name a few.
  • Range adds resilience — developing a broad range of skills and experiences help you adapt to constant change and grow in your career
  • Condorcet jury theorem: the more informed people there are making a decision, the more right it will be. Plurality makes better decisions. See also: wisdom of crowds
  • Law of large numbers: the more data points you have, the more accurate your distribution will be.
  • A large number of independent transactions helps economies function properly and grow. We speak of the economy “moving” and finding many touchpoints to do business on.
  • A lack of diversity can lead to poor outcomes, such as in echo chambers where people are not exposed to different points of view, and develop insular views that are self-reinforcing but usually divorced from reality.
  • Freedom produces diversity, by its very nature — and we do love our freedoms now, don’t we?

Diversity unhinges us because it unmasks our hidden assumption that if we all look the same, we will think the same and thereby avoid conflict.

Deep down, we still secretly hope that we can avoid having to deal with our differences by magically generating conformity.

Our unspoken wish is that, by being identical, we achieve the harmony and collective togetherness we so deeply crave — the collective harmony we mistake for God. In our zeal to commune with god, we instead are far more likely to fall victim to the pitfalls of collective narcissism and all the destructions it wreaks.

Diversity outcompetes monoculture

The opposite of diversity is monoculture… and inbreeding. Monoculture represents sameness, stasis, and stagnation — the system or culture feels fairly dull and stale.

Most people like a certain level of variety in their lives. Some though, have great aversion to difference, change, or both. Authoritarian personalities tend to dislike difference, while individuals with traditional conservative ideology tend to dislike change.

food from around the world

One of the more relatable arguments for diversity stems from the fact that a majority of people enjoy and benefit from diverse points of view, experiences, community members, and beyond. We love to eat different foods, travel to different places, and engage in different pasttimes. And our lives are enriched because of it.

Diversity ought to be celebrated, not denigrated. In many ways it is the very stuff of life — something that helps make life precious and meaningful.

Freedom means the right to make choices. When you have a large population, that means many different kinds of people are making many kinds of different choices for different reasons. That means, mathematically speaking, a broad distribution graph of options chosen over time. Freedom produces diversity, as a direct consequence of its own laissez-faire philosophy.

The Founders knew this. James Madison was an intellectual of his day, and a polymathic student of the great ideas of his time. It is hard not to see the influence of exposure to Condorcet’s theory about decision-making in Madison’s later ideas about diffusing the flames of factions by essentially dousing them in the large numbers of people spreading out within the growing nation. He believed that ideas and interests that were actively opposing each other would be a good way to preserve enough vigor to sustain an active self-governing democracy.

Regardless of the origin, Madison clearly himself was advocating for the power of diversity to preserve the very republic. He believed that this diversity of views in fact provided the structure that would help prevent singular demagogues from rising up too far and destroying democracy forever in their quest for unlimited power. The founders shared this foresight — that giving Americans the freedom to live as they may would lead to a healthy democracy, through the promulgation of different ideas and knowledge as well as through vigorous debate.

You can’t have freedom without diversity

Many who cite Freedom as their patriotic raison d’être do not seem to tolerate well the exercise of freedom by others, particularly others they disagree with or do not like. But as the great Civil Rights activist Fannie Lou Hamer once said, “Nobody’s free until everybody’s free.” She had the insight that if her civil rights could be taken away from her, then no one else’s rights would be safe in this nation either.

America has always struggled to live up to its founding ideals — but it seems like if we want to truly honor their memories, we would continue to take that vision at face value and continue to carry the light of the torch of equality, perhaps upwards to the crest of a hill from whence we may shine once again.

The concept of the Goldilocks Zone reminds us that most typically, there is a range of possibilities above and below which would not be viable. This is in contrast to the idea of unbounded growth, in which one or more key performance indicators is expected to continue to grow forever, without bounds. Think: up and to the right.

Commonly used as a metaphor, the Goldilocks Zone has its origins in planetary science. It defines a planet that is within the habitable zone of its star system, meaning not too hot and not too cold — with the ability to sustain liquid water. Without it, life on the only living planet we know — ours — would cease to exist. Therefore, one good place to look for potential life on other planets is the Goldilocks Zone, which has also come to be used as a reference meaning “the perfect conditions” for some ideal state or goal.

“Going viral” isn’t always desirable

We crave it in our social media feeds, but avoid it like the plague when it is the plague — viral contagion can both giveth and taketh away. In America we’ve recently been having both as of this writing.

Whereas the Goldilocks Zone presupposes limits at both ends, unbounded growth expects no limits to ever be encountered from the start. In a finite world inside a finite universe, it is simply unlikely to be true with much regularity.

You could say that Goldilocks Zones know a lot about establishing boundaries, while the infinite growth areas tend to extremism. Beyond the pandemic, cancer is another infamous candidate for illustrating the dangers of growth without bounds. Arguably, hypercapitalism belongs.

The Goldilocks Zone is a moderate

Goldilocks Zones are akin to the center of the Bell curve; the boundaries of the margin of error; the middle path. James Madison would have been a fan of the Goldilocks Zone — it would have smelled to him like his own concept of the moderating force of many factions preventing too much extremism from taking root in governance, and reminded him of the insights of the Marquis de Condorcet.

“Moderation in all things” was made famous by first the Greeks and later the Romans. It is a kind of ancient wisdom that turns out to have very old roots indeed — back even to the early days of the universe.
