I believe they are very mistaken, just like I believe practicing scientists who also believe in God are very mistaken. There are arguments for and against my beliefs, and I don't want to go into them here. I'm just explaining that to me a spiritual scientist (or a collapse-postulate scientist) is placed in a category where I can't believe that they take their science all that seriously. This doesn't make them impossible to learn from, or not worth it, or wrong about everything, but honestly I'd rather learn from someone more serious and excited about learning like Feynman. Someone who revels in the odd and beautiful nature of reality and doesn't need to invent comfortable intuition-friendly (and complicated) "reasons" why or how something does something.

That said, if such scientists that I put into my would-rather-not-learn-from category want to teach me some math or programming or something solid and backed by experiment, if they want to show me an experiment to learn from, I'm all for it! I grew up in Utah, I can't think of a single influential teacher not a Mormon, obviously I didn't think because they were religious they weren't worth learning from.
