All "personality" type tests are designed to lead to the conclusion they want. We were taught back in like sophmore year of the undergrad how much effort you have to put in to dodge biases and self fulfillment, which probably 90% of the class failed at over and over and just passed regardless with a "now you know for the future!" message.

One of those lessons was to mislead the test taker on the purpose of the test, so avoid them figuring out what you are doing and then lying. Because if you think you'll look like a bad person, you'll give different answers.

Every one of these tests fail that very basic criteria, including basically every poll or political compass test. Especially as, none of these people are going to put in the aforementioned effort to avoid those problems because that would require a high mastery of the English language and a lot of redrafting after fake attempts.
