In my post on Monday, I mentioned an article by Humphrey
Taylor of Harris Interactive that appeared in the recent subscriber-only print edition
of the Polling Report. We asked nicely, and the powers-that-be at the Polling
Report have provided free
access to Taylor's piece.
piece is obviously not the last word on Internet polling, but his argument is well
worth the click. The debate over "non-probability" sampling and Internet methodology
is certainly one worth having.
Finally, in that Monday item, I neglected to include one bit
of full disclosure that should accompany any commentary here on Internet
primary sponsor of Pollster.com is the research firm Polimetrix, Inc. which conducts online panel surveys.
