Dual process account: chapter pushes the idea forward that these really are distinct systems and not just a convenient metaphor.

Experimentally manipulated believability of conclusion and validity of conclusion. Yes: no conflict conditions: because both systems generate the same answer, valid argument accepted more often when correct response was valid, invalid argument accepted more often when invalid was correct response.
