It took five simple rules:
- Question authority: no idea is true because someone says so, including me.
- Think for yourself
- Question yourself: Don’t believe anything just because you want to. Believing something doesn’t make it so.
- Test ideas by the evidence gained from observation and experiment: If a favorite idea fails a well-designed test, it’s wrong! Follow the evidence wherever it leads. If you have no evidence, reserve judgement.
- You could be wrong: Even the best scientists have been wrong about something. Newton, Einstein and every other great scientist in history, they all made mistakes. Science is a way to keep from fooling ourselves and each other.
