You’re right in that you could learn about someone based on their hands. It’s the subjective nature of the predictions that make palm reading unscientific. There have been studies to show that certain health issues manifest in our skin. Palm reading isn’t focused solely on those issues though. It tries to predict all kinds of things (wealth, relationships, misfortune, etc.) How would you create a control group for a study like that?
Still wouldn’t make it scientific. Nothing was tested. It was only observations and imagination. You could all lay in the grass and agree that a cloud shape looks similar to something else. Doesn’t mean a thing.
Not any more than palm reading is a science (it’s not.) It could be considered an art I suppose, but science needs to be things that can be tested and produce repeatable results.
The effects of how this bothers you places you in the group of people you’re bothered by.
I use my bandsaw the most in my shop (maybe second to the sander now that I think of it.) I’ve had a scroll saw I got from my dad’s shop that may have come from my grandpa’s. Weighs a ton. I’ve had it ten years and never used it.
Scroll saw would be more effective for this, but the bandsaw would be more versatile.
I see what you’re saying, and I’m not saying it can’t be useful or even helpful to individuals at times, just that it’s not scientific. It extends outside of what can be tested reliably.
