Right, and this present a small glimpse into why self-reporting is dangerous as well. With exit polls, certain types of people are more likely to report who they voted for, skewing the results. This gets even more extreme when you talk cars and reliability.

Nielsen ratings cancelled many a good show based on sampling. I know where you're coming from. But car samples, though you can't get biblical with them, do hold some type of value. at least an 1/8 value to your total research. The forum is a sample bias as well... But i won't negate it as a 1/8 soursce as well.

yeah, based on flawed sampling...bad sampling processes are the problem. And if you think Nielsen's practices are bad, look at TD...

The problem with corporate sponsored ratings sytem like CR vs Edmunds is that CR may declare unreliability due to a sample set of minor TSB issues vs independents who look for things that the common public consider substantial issues. Long term tests from 8 magazines would be sample testing. C&D brake failure... Sample test. Everything is a sample test in media.

I don't think you are getting the point.
