This is like the COGIATI test, if you one scores highly transsexual, one is going to want to believe it. (assuming you want a confirmation that one is TS) If the celebrity test tells one she looks like Grace Kelly (the movie star turned princess) one is going to want to believe that as well, as a confirmation of her beauty and/or femininity.
Although it might be possible to come up with a test that measures gender traits, it is beyond the reach of science to devise a formula for beauty.
Doug Ousterhout, who virtually invented Facial Feminization Surgery, has told me that even though a large part of his work depends on science (measurements like distance between the brows, eyes, top of the forehead, etc.) a lot of what he does depends on his artistic eye.
