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.

For people with hearing issues, your video is difficult to understand because the black and white jitter obscures your mouth for lipreading. Hope someday all video will be automatically encoded with Closed Captioning.

As time permits, I'm working through my videos adding captions. Those with captions will contain [cc] in the title. By the end of the year, I hope to have done this for all videos.

Who said you look like Garth Marenghi? In this video you look like Nick Frost.

[TheraminTrees]

'In this video you look like Nick Frost.'

—That's a new one to add to the list.

this makes everything make so much sense!

one of life's mysteries for me was how complete idiots remain so smug about it

[Michael Bertrand]

Next time someone is doing something incredibly stupid and can't seem to understand why it isn't working, I am going to say "But you're wearing the juice!"

[petec17]

Damn. I really hope my feelings of superiority up to this point haven't been an illusion. I DON'T WANT TO BE STUPID.

Your video is wrong

[Rhys Oliver]

I think you look a like Bill Hicks a stand up comidian in his revalations show. sorry if youve heard this one before.

[IIJG27Rich]

Loved it. Just one suggestion and please don't take offense but the flashing on the face is dangerous for epileptics like me self :)

Hi Link! Hope all is well. Just stopping by for a refresher on the Dunning Kruger Effect. Was thinking about it the other day but couldn't remember what it was called. Must say something about my competence, huh? ;)
