What I believe isn't relevant. The issue here isn't belief; it's facts. McNamara doesn't assert anything. She tells you what she did to test the claims, and notes, correctly, that her data shows that the claims are not borne out by facts. When someone is confident that they understand something, but fail the ordinary tests of understanding, like being able to answer simple questions, that's false confidence. If you really want to see people grow and blossom, it's important to have respect for facts and the world as it is, as well as each person's potential. Recognizing that the earth is round, or that PhotoReading doesn't work, is not arguing for limitations. When something doesn't work, and you find that out, it frees you to find something else. Seedlings can't grow into trees unless they get what they really need. An acorn planted in dry sand will not grow into a gorgeous oak, no matter how much confidence it has that sand is water.
