I grew up thinking everybody was right. Age gave a person authority, and I assumed that meant that whatever they may have told me was also true. The first time I remember this truth falling apart was when I was in kindergarten. The teacher told us clapping once meant yes, twice meant no. Later that day my Dad asked me a question and I clapped instead of answering. He repeated the question, I clapped again. Our communication broke down because one clap did not mean yes. I remember being yelled at for not answering his question. I thought I had. But instead, it was only a clap.
Now once we assigned value, sure, one clap meant yes. But this was the first time in my mind that I can remember two authoritative sources conflicting in their information they presented. Sure, it's a little thing. But I remember as a young child, this caused a lot of conflict in my little mind.
Another example came years later when my home economics teacher taught us that a microwave heats food from the inside to the outside. I accepted this information as true and moved on. Years later my appliance repairing uncle corrected me, saying it heated from the outside in. This conflict was very difficult to resolve (and happened in the early 90's so google wasn't an option). I did some tests on my own, to see where stuff was getting hot at when cooked.
Sure enough, the inside of a ham was still cool, while the outer later was warming.
What else was I taught wrong?
Over the years I've accepted a premise that everybody is wrong. I trust very few things I hear at first glance. I always check, and recheck, and still remain a wee bit skeptical. Willing to change if presented with the right evidence.
Just a thought I had that I needed to put pen to paper on. I hope you don't take my word though for anything I've said that you believe to be true. Enjoy!
