There's some serious spin in this paper. They use the words "intuitive" vs "reflective" to describe answers dozens of times, whereas they use "correct" vs "incorrect" less than a dozen... but reading the actual objective description of the study, it's clear that a subject who intuitively gets the correct answer gets called "reflective" in the results, whereas a subject who reflects on the problem for a while but still gets the trick incorrect answer gets called "intuitive" in the results.

I don't think the distinction between easily tricked and not easily tricked can be best described as if they were two equally valid options of "cognitive style".
