But that isn't evidence that the method works. If you're a native tribe, that has an ancient traditional rain dance, it is invoked whenever there is a drought. Sometimes it rains shortly after the dance is performed. But if it doesn't rain, it's not proof that you danced poorly, it's evidence that you didn't understand the situation fully or properly. The instructions or "wisdom" you relied on, didn't actually capture something useful.
