CD Copy Stopper

CTho9305 writes "Technology Review has an article about a new CD and DVD copy protection system by Doc-Witness, where the disc itself has a smart card on it. The card checks if a request is valid, and then returns a key to decrypt the contents of the disc. It apparently works with standard drives."

50% below average... not true

[TibbonZero]

Actually, this isn't true.
Anyone below average scares the crap out of me and, by definition, that's 50% of everyone.

Let's look at a few IQ's- 90, 90, 90, 95, 100, 180.
With these numbers, the average IQ comes out to be 107.5. This puts 83% of the population to be "Below Average".

It can also work out the other way.
20 (vegatable), 50 (retard), 120, 130, 125, 100, 115, 180.
The average of these numbers comes out to be 105. So that putss 75% of the population above average.

Now you say, "Well isn't 100 supposed to be the average IQ? Well, yes, but as you can see, it doesn't always work out to be the median number either. Truthfully the average is probably a little higher or lower. But then you have to ask yourself who you consider...
To make everyone take it you have to factor in language (which many IQ tests factor in), problem solving, etc.. which can all be somewhat screwed up. A dolphin has a pretty high IQ as things should go, but he can't tell me if Cat is to Kitten as Dog is to...
yea, and then we have to factor in those with mental problems, or mental gifts. Those people throw things off pretty well. Then some people are uncaring or unwilling, which would pull the scores down more. What about people who have a huge problem speaking and dealing with people, but can spit numbers out at you (hmm, Pi...)

Anyway, 50% of people are not below average, nor are 50% above, even if it all averages out to "average" IQ...
