Later, I did lend too much credulity to pyramid power, although I'm proud to say that I tested it and reported negative results, rather than making excuses.
I remember doing science fair experiments in 6th grade on pyramid power (it being the 70s and all) and the previous year on psychic card reading. Both turned out to be bunk.
Maybe my first skeptical experience involved Sunday school when I was perhaps 5 or 6 years old.
The Sunday school teacher drew a wavy line on the chalk board and a straight line above it and asked if the top line could make the bottom line straight. No one answered. I think that, like me, they all were confused by such a silly question. Adults weren't supposed to ask silly questions, so we furrowed our brows trying to figure out what we were missing.
The answer was that the top line can't make the bottom line straight. So God can't make us do right. We have to choose to do right.
But more generally, I couldn't see any difference between the Bible stories and my bedtime stories. My mother told me that the bedtime stories were make-believe. And they didn't seem anything like the world around me. So the difference was plain enough. Then the grown-ups turned around and tried to tell me that these particular bed-time stories were true. That's when I seriously started to distrust grown-ups.
I already distrusted other kids. And I reckon that was really my first skeptical moment.
I was the youngest-but-one of all the kids on my block, and the youngest of 3 boys in my family. I learned pretty quick that anyone older than me was more likely to lie than to tell the truth, even if it was just so they could have some fun.
Telling lies to little kids was always great fun. Whether it was older kids wanting a joke, or adults with their stories of Santa Claus or the Easter Bunny or the Bible, or big brothers trying to make you feel small.
I then decided that the best way to approach the world was to go first on the theory that everything I heard was false -- either deliberately or by mistake -- and to change my mind only if convinced. My experience in school didn't change that attitude any.
