There’s a short, little book called *How to Lie with Statistics* that I believe was written in the 50’s, that discusses that whole topic.
I had to read it for one of my science classes in college and I was so glad I did.
It was really eye opening in how statistics is manipulated to produce the results you want, and yes, taking polls until they get the results they want is one of the methods.
If you can get a copy, you should, and you should read it.
Maybe your local library has it.
If not, I do recall seeing it on Amazon and it is not expensive. Reviews are interesting.
Thanks, I will see if the library has it.
