I kept seeing this pattern emerge, and couldn’t find a good name for it (originally in reference to failures of the free market), so I came up with one. Simply put, The Tragedy of the Selfish is the situation that exists when an individual makes what is logically the best decision to maximize their own position, but the sum effect of everybody making their best decisions is that everybody ends up worse off rather than better.
You buy an SUV, then other people do, because they want to be safer too. Except that if enough people make that same decision, you’ve overall raised the chances that if you’re hit by a car, it’ll be an SUV, which will do much more damage than a smaller car. Everyone is better off if everyone else backs off and drives smaller cars.
You buy a gun because other people have guns. Then other people do, because they want to be safer too. Then… you see where I’m going with this. Perhaps you’ve made yourself safer in some limited way, but you’ve decreased the overall safety of the system.
This is not safety, it’s mutually assured destruction.
