Almost any poll can be manipulated to get any kind of response that the financing organization wants.
For instance, did you know many political polls are weighted with respondents in one political party or another, depending on the desired outcome? That fact alone would seem to cancel any effectiveness the poll might have, but polls continue to be reported because the uninformed reader/hearer/watcher never looks into the poll internals.
So when you hear this many people believe this, this many people believe that, don’t put a whole lot of stock in the findings.
That said, here’s a poll on the Bible that reports some pretty interesting things. But since it’s an American Bible Society report, believe what you will.
On this Easter eve, 77 percent of Americans believe morals and values are declining in the United States, and the most-cited cause for the decline is a lack of Bible reading.
