More diverse than the stars in the sky? It's a bit rich to suggest that psychology and art can't be formulated into strict laws. Pop music and advertising are some great examples.
You're right that psychology and art can be defined into strict formulas. In fact, they're much better at being put into strict formulas than most of astronomy. That's the main issue: when it comes to psychology and art, we significantly move the goal posts comparted to what we ask of physicists, and I say that as a research physicist.
As an example, I know practically nothing about psychology, having only taken a single intro semester of it at university. That said, from reading your post, I can already make the following claims:
You have a mass of 200kg ± 300kg.
You have a temperature of 310K ± 3K.
Your age is 60 years ± 55 years.
I'll let you pick any star in the sky. Can you tell me the mass, age, and temperature to the same accuracy?
