Observational bias. Rationality of thought process in non-technical situations is rarely externalized; unless you talk of scientists, you're highly unlikely to remark on how highly rational he is being. In fact, the only way I can come up with to make such a statement fit in literary fashion is when you're making a quip on someone:

"It was highly rational of Nixon to start the Vietnam War."
