Oh! The cognitive functions test.

INJs are always testing badly on a particular one, with Si higher than Ni because frankly, the Ni questions make no sense to Ni-dominant users. Because Ni feels 'natural' to them and has no mystic aftertaste whatesoever, they score lower on Ni than SPs and even NPs.

Then again, that's provided it's the same test...

And, one big difference between ISJs and INJs is that SJs find a meaning in routine, while NJs tend to have strict routines because they'd rather just set their physical world to automatic... or so I've heard.
