many have heard this illustration of how hard it is to stop the inevitable movement of wood, but I will share it here again in case some have not. In the past, for thousands of years going all the way back to the Egyptians, huge chunks of stone would be quarried by drilling holes in the rock face and stuffing those holes with sawdust and wood chips. Then water would be poured into the hole. The expansion of the wood as it takes on water is so unstoppable that it would expand and split of at times hundreds of tons of solid rock.
I realize that twisting is a different scenario than expansion and contraction, but there are nonetheless similar forces at work here. In my experience, it is best to assume that you can't stop wood from twisting, it will do it eventually no matter what you try and do to stop it. Perhaps the best we can do is slow it down, or hide it a bit. The best practice is to be selective with your wood. learn what trouble wood looks like. In general, the wood will tell you if is going to twist long before it ever does.
