I do have some "relational rules" that I've derived that seem to create maximum potency and efficiency for relationships, but they're still more principles to me ("these things work") and THEN comes any value I attach to them personally.
Exactly. Clean and elegant is a priority. Then again, could we call this a 'value' for INTPs? After all, not everyone shares it, and it's an arbitrary rule that we apply to what crosses our desk.For example, "efficiency" of a process or system is something I think any good system or theory incorporates. If it's dirty or messy, I don't like it, doesn't fit my idea of what a good theory or system is.
Yup, good anecdote.You'll notice that as Einstein got older, he had several ideas about the Universe that he found difficult to accept because they violated those principles. He hated Quantum Mechanics because he loved the idea of a deterministic universe, and he hated the idea of a dynamic universe, because he had always thought it eternal. It's why he invented things like the cosmological constant, simply to satisfy those principles.
