You sure trust your eyesight a lot more than I do. The thing is, if we really want to know what's going on, mere visual observation won't get us anywhere for the simple fact that there are no muscles in the fingers (everything is in the palm or forearm). Everything that is happening in your fingers is just the result of an action higher up in the hand or forearm. In other words, anything you're seeing is just the result of a root cause that is not in the fingers. And to determine what that root cause is, you'd need medical imagery, not eyesight. Even if you were able to determine that this or that joint did move or not, you wouldn't be any closer to understanding what is actually happening unless you have the anatomical and medical knowledge to interpret that observation. Seeing is definitely not believing, at least not for anyone who tries to uphold any reasonable standard of proof. My wildly uneducated guess is that people who have problems because they were taught to play "from the big knuckle" have those problems because they are using unnecessary muscle tension to keep the fingers rigid. And that problem can be solved by focusing on being relaxed. And if they're looking for that muscular tension in the fingers, they're simply looking at the wrong spot. They should be looking at the palm and forearm. edit: my bad, there is one kind of muscle in the fingers: arrector pili, the one that, when it contracts, causes goosebumps.
