When you see a big change, doubt it

Faced with a big change in responses to a particular question, some announce a major shift in public opinion and scour the world in search of a cause.

By contrast, when I see a big jump in the numbers, as my staff will attest, I respond by saying, “Let’s figure out what’s wrong with our poll.”

This week’s announcement by the truly great pollsters at Marist illustrates the difference. CONT.
