In physics, there is the concept of thermal equilibrium, which simply states that two objects at different temperatures will reach thermal equilibrium because heat energy will flow from high temperature to low temperature. For example, a cup of hot coffee left to stand will eventually cool to room temperature. The small amount of coffee cools down, and the great big kitchen warms up, if only a tiny bit.
From an empirical perspective, this tends to hold true in personal interactions as well. The physics of relationships, to coin a phrase, show that intelligence tends to flow from areas of high concentration to low concentration. If you hang around with people smarter than you, you tend to learn things and get smarter. If you hang around with people stupider than you, you tend to get stupid.
For me, this begs the question: what if you have a person and an imaginary, inflatable, photoshopped sister-type person, both at, for lack of a better term, “absolute stupid?”
Does anyone get any smarter, ever?
