Brainpower is analogous to horsepower, which is a measure of work done over time. I claim that intelligence has two primary subfactors, comparable to:
- Current and Voltage in electronics
- Flow and Pressure in pneumatics and hydraulics
- Clock Rate and Instructions Per Clock in central processing units
This will be a purely formal description of the model, so it isn’t necessary to know what the physical units of measure are at this point. The idea is that we can already begin to explain some of the high-level phenomena by analogy to other types of flow systems.
I’ll refer to the two intelligence subfactors as mental speed (S) and mental caliber (C). Mental speed refers to the quality possessed by people who can solve problems very quickly, whereas mental caliber refers to the quality possessed by people who can solve very difficult problems. You can imagine measuring these two subfactors as being analogous to measuring the explosive power of a football player by multiplying his 40-yard dash speed by his weight class. It is absolutely essential to understand that I chose these terms for colloquial impact, and not by extension of the physics analogies above. I did this so that people who’ve never even heard of this obscure blog can have a pretty good idea what you’re talking about just from the terms alone, even if they don’t have a precise definition to hand. However, this may be confusing for you in the short run: just remember that every other physics term in this series of posts will be used according to its precise, established definition (e.g. weight, friction, work, power, etc.), except for the terms “mental speed” and “mental caliber” which are just placeholders like X or Y.
Recall, intelligence is a person’s capacity to solve problems, where I define problems as non-material obstacles to objects of desire. S = problems/second, whereas C = difficulty/problem. To wit, g = S * C = brainpower.
Please compare this with my anthropological brain matter theory. That’s the connection I’m intending to make eventually. I believe that overall gray matter mass predicts a person’s mental speed whereas overall white matter mass predicts a person’s mental caliber. Think of these as being comparable to the specifications for the amp and volt capacities for an electronic system.
