But what good reason is there not to? How can you be worse off from knowing in advance what you’ll do in the worse cases?
The answer seems trivial: you may have wasted a bunch of time and energy performing calculations relating to what to do in a hypothetical situation that you might never face.
If the calculations can be performed later, then that will often be better—since then more information will be available—and possibly the calculations may not have to be performed at all.
Calculating in advance can be good—if you fear that you may not have time to calculate later—or (obviously) if the calculations affect the choices to be taken now. However, the act of performing calculations has associated time and energy costs—so it is best to use your “calculating” time wisely.
