It goes a bit like this. Most human actions have side effects in addition to their main purpose. Some we are aware of (and may trouble our subconscious), some we are dimly aware of (and brush aside), some we find out later (perhaps to our regret). Not being aware of them causes reactive behavior and goal confusion and reduces the power to act.

Increased awareness of them allows us tackle them effectively, but requires lot of brainpower most of us are unwilling to spend.

Meditation allows one to simplify a problem so one can see its dimensions clearly (less brainpower needed), then allows one to weigh solutions along with their side effects (to get an overall better solution).
