Hurdling past covid

One way to think about “adoption” is as series of hurdles. If something is “adopted” it has succeeded by crossing the set of hurdles. There are few food bacteria “adoptions” because of hurdle technology: hot, cold, salt, and acid all make the process harder for food bacteria to survive.

Another metaphor for this approach is Swiss cheese: one layer has multiple holes but if the layers are independent, then stacking one on top of another removes the holes.

Part of the problem with studying, treating, and living with Covid is that it’s hard to figure out what works. There are models, but we’re still kinda guessing. As of August 2021, more than one-fifth of all FDA approved drugs were tried as off label treatment for Covid. Ironically, there’s not enough Covid to study it.

“What should give us reason to be hopeful is that there’s this cumulative effect that if you give the right drug at the right time along the way…there are these 15-30% reductions at each step so if you are someone that gets a monoclonal antibody early on, if you get fluvoxamine, you get remdesivir on admission, you get dexamethasone once you are on oxygen. We should model out where this puts you at.” – David Fajgenbaum, Wharton Moneyball, August 2021

Ah not so fast, Eric Bradlow follows up. How independent are these? Is this like a piece of Swiss cheese? “It’s shocking,” says Fajgenbaum, “they all seem to hit it from a different angle.” That angle appears to be time. Vaccines are like sunscreen, David explains, and that’s the pre-infection prevention. Then it’s one drug to stimulate the body’s immune response, then it’s another to slow that response way down.

Abraham Lincoln is attributed as saying, give me an hour to chop down a tree and I will spend the first fifty minutes sharpening an axe. Rather than trees and axes we can ask: Is our situation a hurdle condition? With Mr. Lincoln and the suggestion of Charlie Munger to invert, always invert (!), we can come up with a simple situational:

For deceleration, we want to create a series of independent hurdles an agent must cross. In the case of covid this might mean that a place mandates masks, vaccines, and social distancing — or maybe just be outside.

For acceleration, we want to create fewer hurdles for an agent. If not possible, we want homogenous hurdles. Smartphones did this for ride sharing: the who (payments), where (location), and when (on-demand) were all integrated into an app. Another way to consolidate hurdles is find the JTBD.


Even 17 months into it still feels early to say these are the treatments. While they may not be this approach still feels okay.
