I'm more interested in this need to convince people of something that hasn't been close to being proven in many decades. It is very much a Great Pumpkin sort of thing...
You know - it's OK if people don't believe you.
Well, at least you noticed the graph.;-)
I knew of a guy once who got laid off from his job and he would still drive to the office each morning and just sit in his car in the parking lot. The security guard, who knew him, would go over to him each morning and try to tell him that he couldn't do that, that he was scaring people. And my friend would look at the security guard and say, "What are you trying to tell me? I work here."
Turns out the guy hadn't even told his wife that he had been laid off. Security had to call the wife and get her to convince him not to keep driving to the office each morning.
And, frankly, it's not like this guy was crazy. He just couldn't accept that he'd been laid off (his entire department had been cut).
Apparently his wife eventually convinced him because he got another job and life returned to normal.
I joke about denial, but it is VERY common.
