We had fun applying all of this to my daughter's recent discovery about the truth about Santa. We went through her pre-truth reasoning: The experts (i.e. my parents) tell me Santa is real, I observe that the presents 'magically' appear on Christmas morning, and I desperately *want* Santa to be real - therefore he *must* be real! And then her post-truth reality: The experts (i.e. my parents) had a vested interest in perpetuating the Santa myth (it's fun!), the presents were indeed there, but were not placed by Santa and, finally, just because I *wanted* Santa to be real does not negate the laws of space and time.
Anyway, the book goes on to explain the five steps of the Scientific Method - perhaps not the most riveting reading, but still nicely done. And, finally, encourages children to *constantly* ask questions and apply the Scientific Method to find the answers.
