Where It Fits

The rule works for any choice made in order with no going back: picking a parking spot as you drive deeper into a full lot, hiring from a stream of applicants, or accepting a job offer before the next interview. The shape is always the same — options arrive one by one, and saying no closes the door for good.

Real life is messier than the math. If you can sometimes circle back to a rejected option, a shorter look-around phase is smarter, since the cost of passing is lower. The 37% figure is exact only when rejecting truly means losing forever. The lasting takeaway holds either way: commit neither too early nor too late.
