The thing is, and we do not collectively teach young, is that many decisions are workable but some have bad consequences that are nigh irredeemable. Then there's the sunk cost fallacy, all too common. Estimating the cumulative sunk costs and arriving at robust decisions is feasible. Choosing a college may be a cost, but for now there are workable alternatives. And you always have the way to know or at least roughly estimate which is good enough for a sane decision. You just take the cost of acquiring information into your decision time and you're gold. Apply hard limit for time and problem disappears. You did the best you could given the constraints. In fact, the typical problem today is that you have too many ways to know and not enough ways to verify veracity.
