That means that if the members of a special interest group simply ALWAYS answer the calls from pollsters, their opinion will register 11 Times their actual percentage of the sampled population!
For example, we just now got a call from a special interest group interested in drug rehabilitation ~ I elected to be among the 91% whose opinion wasn't actually reflected and not the 9% who answer their questions.
The Paulistas should jump for joy!
There’s enough secret sauce being slopped about now to drown in it.
When I studied political science as a non major subject in college (I majored in engineering) I was told about polling methodologies that would move heaven and earth to get a scientifically accurate sample. And it took weeks if not months to do that.
