Intelligence as Mental Entropy Regulation

The central thesis is deceptively simple: intelligence is not how much you know or how fast you think — it is how effectively your brain manages mental entropy. Every waking moment, your mind confronts an ocean of possible interpretations, decisions, and reactions. Entropy, in the cognitive sense, is the raw disorder of all those possibilities before your brain collapses them into a single coherent experience.

A high-entropy mental state means many possibilities are active simultaneously — you're uncertain, exploring, generating options. A low-entropy state means you've resolved that uncertainty into a clear decision or understanding. Neither is inherently better. The skill — the intelligence — lies in knowing when to let entropy run high (exploration, creativity, insight) and when to collapse it efficiently (execution, decision-making, recall).

This is what we call entropy regulation. Your brain does it constantly, automatically, and it is the single process that underlies every cognitive ability BIQ measures.
