Different cultural groups score differently on your test. (MMPI Pre 2008)
What is an indication of bad cross-cultural validity?
The PAI was normed in the 1990s, and the average amount of self reported depression and anxiety symptoms has increased since then. (Uttl, Sikma, & Tat, 2025)
What is a potential risk for inflated test scores caused by a non-representative sample?
Most of the research done on the MBTI has been done by people who sell the tool or regularly use it
What is conflict of interest?
It increases the chance of false positives and over-diagnosis of psychopathology
What is the problem with doing a "full panel" to test for every kind of psychopathology?
It can be helpful for catching symptoms or diagnostic specifics that a psychologist might not think to ask about (eg. OCD).

What is non representative sampling?
People tend to get different scores over time when they take the MBTI
What is bad test-retest reliability?

What is an example of good face validity?
Your test has scales measuring similar traits and sharing common items. (MMPI Pre 2008)

What is the problem with a personality test having binary categories?
No one acts consistently 100% of the time and in all contexts.
What is the problem with trying to predict how people will behave based on traits?

What is something the PAI can offer to supplement clinical interviews?

What is a risk factor for over-diagnosis of paranoia in marginalized populations?
Psychological research and theory in the 1930s was primarily rooted in single practitioners observations while working, and did not have structured methods for testing validity like we do today.

There does not appear to be any evidence that "thinkers" and "feelers" represent differences we can consistently measure between people.
What is bad construct validity?
