One-quarter of all Americans met the criteria for having a mental illness within the past year, and fully a quarter of those had a "serious" disorder that significantly disrupted their ability to function day to day, according to the largest and most detailed survey of the nation's mental health, published yesterday.
Although parallel studies in 27 other countries are not yet complete, the new numbers suggest that the United States is poised to rank No. 1 globally for mental illness, researchers said.

This is hot stuff. I suspect it's the 25% that vote Bush.

Besides your reference to Bush voters, what does this have to do with US Politics. This post is nothing more than trolling.

1.) I believe this survey to be complete B.S. What exactly are they using as Criteria!? I know far more than 8 people, FAR FAR more than 8 people in my life-time, and I can only really thing of 2 that are crazy, and only one of them that can't function well in society as a result of this. Funny how they don't mention what they use as criteria. And no, you can't take 9,000 out of 295,734,134 people, and say it represents our country. That's like (Roughly) taking 9 out of 295,734 people, surveying them, and saying that they represent the whole group.

Do you not understand the concepts of statistics and averages?
Just because you have never met a mentally ill person does not mean the figures given are false. If they are right then it would mean that there should be approx. 73million mentally ill people in the US. Now what that means is that you could meet 221million US citizens without HAVING to meet a mentally ill one, since you could meet all those who are not classed as mentally ill. It still would make the figures correct.
As an aside have you considered that there is at least one more "crazy" in your group who is bringing the average up?

There are 100 jelly beans in a jar. 25% of these jelly beans are black, and the rest are white. If you completely mix them up, close your eyes, and make random selections, what is the probability of you drawing a black jelly bean?
One out of four; you would not keep choosing white ones until all that are left are a bunch of black ones. Do you see what I mean here?

I think your maths is a bit rustier than you think.
Using your bean analogy what it the minimum number of beans you need to draw out to guarantee a black bean?

Well, technically you could get a black bean on the first try. The minimum number you would need to draw before you can 100% GUARANTEE a black bean would be 76. But I've already brought that up... It's would be very unlikely that would draw 76 before getting a black bean. Chances are, if they were completely mixed up, roughtly one in four would be black.

Well done, what you have just shown is the relationship between real life and statistics.
Statistics only show probability not actuality.
Try not to confuse the two.
Just because statistics say that one in four Americans are a certain way does not work out to the actuality that if you have just passed 3 Americans who were not that certain way then the next one has to be.
