It doesn't contradict it, no. What it does so is provide evidence that your otherwise-unsupported opinion may be wrong.
So after 8 people, your 50% statistic is evidence that my opinion that you'll probably have a problem with wisdom teeth is wrong?
What if you came up with your statistic after only the first two posts? You'd have 100% statistic. Since your 50% statistic may prove me wrong because that 50% may stay constant throughout the entire population, would your 100% statistic do the same?
They could also be Kings of the Outer Planets, whose teeth are made of diamond.
Which would be just as likely as someone having overcrowding from wisdom teeth.
You can't invent conditions then base your conclusions on what ifs.
You came up with the 50% statistic to refute what I said. 50% of those people still have their wisdom teeth. I never said more than 50% will have them removed, I said you'll probably have PROBLEMS with them (so let's assume probably means more than 50%). Still having your teeth doesn't equal no problems, so you're basing your conclusion on an incomplete statistic.
It is a significantly better representation than is zero - by an order of magnitude or three .
I was the first one to say that my "evidence" is quite sketchy (n=8). Nonetheless, it's stronger than a mere opinion. It should be trivial to refute my little poll with stronger numbers.
I don't remember seeing you say anything about your evidence being sketchy.
I have a greater number of people than eight that I personally know who could be a better representation. But that's not proof, so I tried to find a statistic online that fits my specifications. It's not easy.
I picture you as one of those Geico cavemen who took offense to my neanderthal comment. I admit, it's most likely the difference in teeth size that affects it more so than people having gigantic mouths.
But I still firmly believe most people will have problems with their wisdom teeth, in one form or another.
