IMHO that's a really important point. You get a better grasp about consequences of your choice after trying several options and seeing how the consequences of different actions differ.

The best laboratory example of this is playing go on a computer. Typical go software records your games, and then lets you replay, play different variants, analyze when things went really bad after a silly move, etc. After a while you get a tree of diverging game records. In some you won, in others you lost. It's a good learning experience.

(disclaimer: I'm not sure how to un-compartmentalize this learning to be applicable in real life, not just in a game of go)
