I love Y Combinator, and I'm proud to be a part of it, but I've been thinking a lot about this recently...
Many many organizations exist, whose purpose is to filter people who want to do something down to the few percent who are most likely to succeed at that thing, and then to help those people get even more likely to succeed at it.
But that seems like it's actually a kind of operating on diminishing returns. If I take someone who is 90% likely to succeed at something, and help them to become 95%, is that really a better use of my time than if I take someone who is at 50%, and bump them up to 80%?
From an investment point of view of course I can see why people would do the former. But I wonder if the world might be a better place if we could figure out how to do the latter?
