The data is accurate... it is the Arbitron ratings.

Yep,
as accurate as whomever with free time to participate in the survey
faithfully keeps their diary.

You obviously don 't know that there are studies that show that
no-participants have essentially the same behabiour as participants?


Never mind the spelling flame,
just try and focus on the illogic of your comment.
hint - how is a non-participant studied?

Non-participants are often studied for all kinds of research. In a separate
study, a refuser or non-participant will be recontacted in a different
manner, often with a much higher incentive, to discuss non-participation.
This often concludes with a measure of the original behaviour originally
solicited. Usually, an explanation that "we are studying what kind of
dishwasher liquid people who normally don't participate in studies use, and
we are willing to send you a $100 gift card if you will just ask a few
questions" will get nearly full participation.

The study of nonregular participants as a verification of the willing
participants shows the behaviours to be pretty much the same.
