"Should we give those up as well?"

No... because those have been shown to work...   Unlike Divination, Dowsing, Sailing Off The Edge Of The World.... all of which fail any decent double-blind test at a rate that consigns them to the realm of random chance

You wanna throw dice to decide your action, go right ahead... Don't try to tell me that "The Force" is controlling those dice.... Cause I've flown from one side of this galaxy to the other, and I've seen a lot of strange stuff, but I've never seen anything make me believe in one All Powerful Force, controlling every thing... There's no mystical energy field controls MY destiny... It's all a lot of simple tricks and nonsense....
