I think the OP's point is after filtering out obviously non-successful startups, the chance of success is potentially non-correlated with other "traits", "characteristics", or "metrics" etc. that people often associate with successful startups/founders.
It would be an interesting experiment if YC lower the acceptance threshold to say twice the original batch, and randomly pick from that bigger pool, and see if there's any difference between the ones that didn't make the original cut and those did. (A/B in its finest :)
