Estimating uncertainty is preferred, but if you have people who insist on a single number, then teach them that it should be the median instead of the mean. Means tend to overvalue "moonshots" where there's a 99% chance you lose money, but if the payoff in that 1% where you win is large enough, it can still result in a positive mean. And a mean can often be an outcome that isn't actually possible, but falls between several options, while a median is always an outcome that can actually happen, and there's ~50% chance you'll get a better one.
