Your personality?

[Froge]

I dislike playing the "I've studied this so I know more than you" card, but having taken a few higher psychology courses, I am well aware that Jungian tests are hardly accurate indicators of one's personality.

To put it simply, self-report data lacks validity. Information found through surveys or questionnaires pretty much always have the potential to suffer from confirmation bias, self-serving bias (or modesty bias if your cultural paradigm leans towards collectivist), and possibly also demand characteristics. The most credible indicators of personality are found through observations of behaviour within either controlled conditions (but not too much, since laboratory experiments suffer artificiality), or through strong correlations identified by field observations. Furthermore, this personality test makes use of only nominal data at best because its only possible answers were "yes" or "no", which basically throws you into black-and-white regions of categorization.

That said, quizzes like these are still very fun and I like to see where my own confirmation bias takes me.

Edit: Perhaps "confirmation bias" isn't the best term to describe the idea that self-report data has little validity. What I basically mean is that the way a question asks you to judge yourself could cause you to lean towards certain expected ways of self-perception that may or may not be true of how you actually behave.
