The map
Cost of failure,
against what they built.
Each dot is one person, placed by cost of failure across the bottom and the size of what they built up the side. Think of it as a picture of where these people ended up, not the odds of ending up there. Everyone on it succeeded. At every level of risk, the ones who didn't make it are missing, because nothing keeps track of them.
Everyone here made it, and that's the catch. Plenty of people started in the same place and didn't, and they don't show up in any dataset. You're only looking at the ones who came out the other side.
