Hiya! Welcome to Less Wrong.
That sounds like a good experience to have as young as possible, finding out that your world view is susceptible to being wrong and needing to be changed. The longer you wait for the first one of those, the harder it is to avoid just closing your eyes to it. Now, though, you're more mentally prepared if it ever happens again.
It sure was. As you can guess I'm not your average teen. Hopefully this time advantage will give me a head start on Rationality, and allow me to go far with it.
