1. You can't prove that, its simply an assumption.

2. Again, people assume this but there is no proof.

3. You seem to believe this is non-trivial? Certainly this is true of far more than just OC graphics cards...

I haven't said that it is a good, or a bad thing. I'm not some kind of simpleton who would try to reduce it to those terms...

Interesting, if some bizarre, choice of example. I assume there is always some bias and error in reviews. I'm happy as long as they disclose exactly what they are reviewing so that I can judge for myself. You seem to believe that a review can be representative of an entire class of products, and that the single sample holds some kind of statistical significance. In your naive world, did the imaginary reviewer mention the $100 bill in the review?
