Are the result conclusive? Are the result based on solid findings? Are the result reliable, the truth about who you are?
Basically I have no idea how they do it. But it is still fun taking them, trying the test out.
Here is one example of such test. The test is said to be attributed to Oprah's Dr Phil. or so they say. Before and taking the test. there is a disclaimer.
"Nobody, not even a quiz like this, can tell you conclusively whether this is truly how your friends see you or not. In fact, although this quiz is attributed to Oprah's Dr. Phil, we have no way of knowing whether it has any basis in empirical research or not. So you should take these results as something for fun and not too seriously. (Supposedly Dr. Phil scored a 55 and Oprah scored a 38.)" source : Psych Central. Take the test here
Mine... I got a 47 score. What does it tells about me?
The Lively Center of Attention
Others see you as fresh, lively, charming, amusing, practical, and always interesting; someone who's constantly in the center of attention, but sufficiently well-balanced not to let it go to their head. They also see you as kind, considerate, and understanding; someone who'll always cheer them up and help them out.
How did I find the result? Some how true...
