Some human behavior is more naturally modelled in QT than classical probability theory.¹ The major difference between quantum and classical is that you can have incompatible variables which don't have a shared probability space. Nothing to do with physics. Also, with natural units Plank's constant is 2π, so it does show up a lot. [1] https://arxiv.org/pdf/1711.00418.pdf https://arxiv.org/pdf/1711.00418.pdf
