A type-1 moron believes the first thing he/she heard, and cannot be easily dissuaded with later arguments or evidence. Stereotypically speaking, many religious people fall into this category.

Conversely, a type-2 moron favors the last thing he/she heard, readily allowing it to dislodge any prior beliefs, values or intentions no matter how well-founded. Here in the US, our current president can be cited as an example of a type-2 moron.

In reality, we all fall into one or both of these categories on occasion, so it's best not to indulge in excessive self-assurance.
