I think it goes deeper than that. Even if many of these surveys had an
appropriately selected sampling of respondents and the proper analysis
was performed (t-tests, ANOVA, Chi square, etc.) to minimize the effect
of outliers (or out-and-out liars), they would still be relatively
useless because of the manner in which most of the questions are asked
and answered. Most are multiple choice without a scale or option to
skip or provide a 'null' answer, and wording is rarely consistent.
You'd never make it out of an undergraduate research class with any of
the satisfaction or marketing surveys I've seen lately. (Which raises
some other unsettling questions about the sources of these surveys...)
Unfortunately, this doesn't seem to be something that IT marketers have
a lock on, either. It seems to be everywhere (including this years'
election race). So, I guess what I'm saying to anyone still reading is,
please do us all a favor and blow off as many surveys and polls as you
can. If you're going to contribute to the FUD, contribute accurately
(by not contributing). :-)
