Moving toward a less deceptive interface...
So how do we tell whether our mental model is closer to reality rather than just rhetorically convincing? The answer that has slowly emerged in philosophy and science is not a single test but a set of structural constraints that good models must satisfy. These constraints allow us to detect improvement without requiring direct access to reality. By setting these limits, we can check whether we are mentally moving closer to reality or moving away from it.
The sixth constraint is coherence with other well-supported models. When a theory integrates smoothly with a large network of other verified theories, it becomes harder for it to be merely persuasive. Reality tends to form consistent structures across domains. A model that conflicts with many established results must either provide overwhelming new evidence or be rejected.
Taken together, these constraints create a practical method for approaching reality without ever leaving the cognitive interface. You never compare the model directly with reality itself. Instead you compare models with consequences. The model that consistently survives confrontation with the world is provisionally closer to reality.
But notice the deeper implication. Knowledge never becomes final truth. It becomes progressively less wrong. This is why science changes. Each generation replaces models that worked reasonably well with models that work better under more conditions. The interface remains but it becomes more transparent.
The measure of a model is not how convincing it sounds inside the mind but how stubbornly the world refuses to contradict it.
