I've written at length in the past about why Zogby polls, conducted on behalf of the Discovery Institute and invariably showing that a large percentage of the public supports "teaching the controversy," shouldn't be relied upon. I was about to blog about this topic yet again, but Matt Nisbet beats me to it, and does a far better and more exhaustive job debunking the latest pro-ID poll than I myself would have done. Suffice it to say that by touting these surveys, Discovery is undermining the science of polling in pretty much the same way that it is undermining the science of evolution.
