LOL one of my SLE friends got LII and got all angry
Dichotomy tests are easily wrong. Just because it gave the right result for some people, it doesn't mean it works, just that it was lucky. Besides, most of the time with dichotomy tests, your answers change based upon various factors which it doesn't account for. Something I've noticed as a Ti thing about testing taking is when you cannot figure out which response is the "right one" on the test (no matter what kind of test it is), you don't care which one you pick. That alone can throw off the test.
