I've always found these “post your results” things very strange. I mean, if you take the test and get a pretty poor score, how many people are going to post it? You might as well post “Hi, everybody. I scored 4 out of 50. Should I change my name to The Fucking Gimp now or wait a couple of days?”? What they'll do is post a score that they think is 'respectable', perhaps something in the 40 range?
Then you'll get the odd fellow who storms the top end of the scale - 49 or 50. Your genuine genius clomping about in their best clogs chuckling at the elementary errors in Steven Hawking's latest paper. Of course, if you post that score many people will simply think “there's no way he/she's done better than me” and accuse them of making it up. So maybe, they lower their score in a show of modesty. Maybe somewhere in the 40 range?
Of course some people will actually post their correct scores (providing they didn't do too badly (i.e. somewhere outside the 40 range). Other people will then assume they have just inflated/reduced their scores.
The last group, an altogether smaller group, generally lacking in all self-awareness, will simply claim they achieved the highest of all scores, probably quicker than anybody else whilst being pleasured by a Brazilian supermodel in their solid gold house.
So, whatever you post, genuine or not, nobody is going to believe it anyway.
