Are you saying that we're supposed toThat depends on whether you're trying to prove a theory or a psychometric.
1) Start with the assumption that the Grant hypothesis is correct without worrying about evidence
2) Come up with a test that shows a person's Grantian function stack
3) Split test takers into "experimental" and "control" groups (somehow)
4) If the results conflict with the hypothesis, then we throw away the results instead of the hypothesis
Exactly. That's because they are written according to the definitions of the cognitive functions.Even with a statistical approach, unless I'm mistaken function tests have none of that empirical validity.
