segregation

You’ll hear a common retort on the extreme right that now holds sway in the mainstream Republican Party, in response to protests about the dismantling of democracy in this country — that we’re “a republic, not a democracy.” Right off the bat, a republic is a form of democracy — so they are claiming something akin to having a Toyota and not a car. It’s a rhetorical trick, in which people who fully know better are hacking the simple ignorance of civics and basic political philosophy of the right-wing political base.

But it manages to get worse — the origins of the bully taunt “a republic, not a democracy” go way back — they’re actually located in the segregationist movement. Specifically, the concept comes from the pro-segregation book You and Segregation, written in 1955 by future Senator Herman E. Talmadge.

John Birch Society loonies laud “a republic, not a democracy”

The “republic, not a democracy” meme would go on to be featured in the John Birch Society Blue Book — an organization so toxically extremist that even conservative darling William F. Buckley distanced himself from them. They feared the idea that increasing democratization would be a shifting balance of power away from white conservative men, and they spun numerous conspiracy theories to explain this as the result of nefarious undercover plot to overthrow Western Civilization.

This was economist Thomas Schelling’s insight way back in 1969 — just one of many examples of “unknown knowledge” that exists in the world today. His Spatial Segregation Model takes a few simple premises and shows that a set of quite tolerant people, who genuinely prefer to live in a diverse neighborhood in terms of race, income, and other factors, nevertheless end up self-segregating into clusters of like individuals — as follows:

Slight preference for homophily: 30%

We set up a fairly dense environment with a low preference for similarity — people are quite tolerant and are only looking to have 30% of their near neighbors be similar to them:

But when we run the simulation, we end up with an equilibrium state where individuals are surrounded by 75.2% similar neighbors:

If we run the spatial segregation model with a 50% preference for similar neighbors, the outcome is even more stark: the agents achieve equilibrium at a whopping 87.7% similarity:
