I think you've written that QM is in part probability math using complex numbers. I've also read that human decision making doesn't map well to classical probability. Do you know if QM/"complex probability" has been used to build better models of human decision making?
Every few months there's another paper on the arXiv trying to do exactly that. Pretty much without exception, I've found the papers to be terrible -- leaping immediately to QM without first considering more prosaic stories for whatever human behavior they're trying to explain. It's like quantum mechanics is a hammer, and explaining human decision-making is a steak, and all these people want to use the hammer to slice the steak for some weird reason, their strongest argument being that the problem of slicing the steak doesn't map well to their bare fingers. It's amazing what some people think they can get others to swallow just by using the word "quantum"! :-)
