PERCENTILES.
For those unfamiliar with percentile rankings, briefly....

Say you get 95% of questions right in a test — sounds good. But if everyone else does, then your performance is actually average. Percentiles are a method of marking, which ranks your score COMPARATIVE to other scores within a population.

If you rank at the 10th percentile, 10 percent of all scores, in the population tested, fall BELOW you. If you rank at the 90th percentile, 90 percent of all test results fall BELOW you — you've made it to the top 10. 50% is dead on average.

Bizarrely, in a tendency which has been termed the 'above-average effect', it seems most people — no matter what their competence/ability — perceive themselves as above average, hovering around the 60th percentile.

  • I was surprised when I read your comment, thinking "wtf, why?", but then I scrolled up and I see the resemblance :P. I think it's the floating white head effect and the way he animates his face. I guess this points more to the skill of Valve animators to produce a convincing character through an inanimate object rather than anything else.

  • Seriously, what are you going on about?

  • Wow, this happens to me more and more everyday. Thanks for the vid, it has shed light on a mystery that has perplexed me for the past seven years!

  • Now let's go to the mall and play video games while popping pills and eating nachos!

  • FDA Corruption Video MSU-ISS 310. Watch this to understand who your pessimism is really serving...and why. It's the Mayor McCheese and Mac sauce point of view...good for business...of making people ignorant and indifferent.

  • Just being a friend and telling you the truth.

  • Isn't strange who spiritual people tell us we all have limitless potential and to tap into through practice and perseverance, while you tell people they're not worth that much. I think both can become self fufilling prophesies. There's the difference you deny. They go in opposite directions.

  • But keep listening to your Trotyskyite Bush and Iraq war fan, blind faith in knee jerk atheism and dead materialism hero...of wait, I just answered why you feel this way.
