Instincts aren’t irrational. They are a temporal latent variables that are indicative or are a premonition of one possible future. Instincts are derived based on past experiences which have trained your model. Current neural nets aren’t temporal nor do they do online learning. But that will change.

You say instincts are irrational. Many people trust their instincts because they are pretty accurate for them. If it’s irrational, that’s likely because it’s a poorly trained (human) neural model.
