In each of our minds we have a line of credibility. When you first hear a new idea, you place it above or below this line. If you place it below, you dismiss it immediately, often as ridiculous. If you place it above, you’re willing to give it the benefit of the doubt, follow it over time, and continue to make serial judgments. But we also have a line of super-credibility. When a new idea is born above this line, you accept it immediately and say, “Wow, that’s fantastic! How can I get involved?”
