Evening TV Taught Me How To Exploit America

I watched an ABC documentary on American Polarization today. It was obviously made in America, so I was flattered that Australians would care about such an issue. The basic premise was that the current trend in my homeland is for people to live in communities of like-minded people and that discourse among opposing sides was dying. They presented some studies that seemed to explain the phenomena. In short, opinions become more exaggerated when people are in a group of like-minded humans.

I'm trying to figure out how I can translate this information into a swimming pool filled with Jello.
