But is that true? Human behavior has a lot of information. We normally say that this extra information is irrelevant to the human’s beliefs and preferences (i.e. the agential model of humans is a simplification), but it’s still there.
Basically “humans are always fully rational and always take the action they want to” is a full explanation of all of human behaviour, that is strictly simpler than any explanation which includes human biases and bounded rationality.
