-Meet the Robinsons
People are wrong about something every day, whether about the traffic on the Beltway, the weather, the weird guy behind you who turns out to be famous, or about how the Heat are going to sweep the Spurs, etc.
That being said, sometimes, being wrong is a blessing in disguise, or at least is as/more helpful than being correct. Here are some examples.
"Nothing important happened today." (King George III- July 4, 1776). On July 4th, King George III said this; the same day the USA declared its independence from England. He was wrong. The USA won the war, England lost an important part of the New World, and now America is one of the most powerful countries in the world. King George being wrong was a good thing for everyone, except maybe him.
The world was wrong on February 22, 1980, when the USA stunned the Soviet Union in the Winter Olympics. Words can't really do this justice, so watch it for yourself...
I was wrong when I said the Pittsburgh Penguins would beat the Boston Bruins in the Eastern Conference finals. And I have never been so smug. I've been happier, but I've never been so smug.
