> Why did you eat the dinner you had last night? Is this really relevant? This is only a pertinent question if there was some fact that challenged his dinner decision and he decided to ignore it. Why would think that's the case? I do usually choose what to eat based on proper caloric intake, nutritional value, and my mental model of human health based on research that I've done. Most people do. Most people fret all the time about what they're putting in their bodies. If I "cheat" and eat something I know is bad for me, that's not a case of a fact failing to change my mind -- my mental model is still correct. I know that the sugary treat is bad for me, and I am correct. Never in this situation has any clear fact been rejected. Never has an incorrect mental model been used when a better model was readily available.
