Hypothesis: Cognitive functions are antagonistic as predicted by the MBTI.
Null hypothesis: Cognitive functions are not antagonistic.
So, let’s say we made an experiment and made the subjects do something that required extroverted feeling and then after we made them use introverted thinking. We could test if that is harder for people than other combinations of cognitive functions.
So,
Hypothesis: People will have a harder time using a cognitive functions when they have just used the antagonistic cognitive function.
Null Hypothesis: People will not have a harder time using a cognitive functions when they have just used the antagonistic cognitive function.
Well, that at least is an experiment one could set up. Time of reaction should probably be a reasonably-appropriate measure for “harder” (perhaps error rate, too, but on many tasks error rate is trivially low). But this requires to determine how “using a function” is detected; you’d need, at the very least, “clear cases” for each function.

However, just in case, you only covered my first suggestion, not both.
