At first glance, the Pierley/Redford personality test seems too vague to tell you anything accurate or interesting about your actual personality: “Which of these circles is angry?” it asks (and provides two abstract and gauzy illustrations). Or “Which position is diseased?”
But the pictures are pretty, and weirdly disturbing, and so you find yourself clicking through all 20 questions. When you’re done, you get a short, specific thumbnail sketch of your personality type. That’s where the real fun begins: What did those questions mean, and add up to? And how did they get so far under your skin? You can take the test multiple times, clicking quickly and intuitively, or slowing way down to puzzle out the “correct” answers. Either way, you’ll end up wondering: Is it a pretty parlor trick? Or a real window into your deeper, darker self?
