A Fine Woodworking article I read a while back has a picture of Steve Latta dropping boards onto concrete.
The caption reads:
Drop relieves stress. For larger doors, like those on armoires, Latta actually drops rough parts on the floor! The impact releases internal tensions and lets the parts finish warping before final dimensioning, he says.
I thought there was an accompanying video but I couldn't find it with a brief search.
I have a great amount of respect for any professional woodworker, but to me this seems really sketchy. Is this true, and if so, how would you explain it to a 5-year-old using pictures? Are there any studies which have measured and confirmed or debunked this claim?
