And you get to the heart of how I can tell someone the truth and they go right on to ignore it. Consider: pearls and swine. This issue of turning schools into psychological laboratories is discussed in detail in several books. Pride might have something to do with it: people think they know something when what they "know" is what "most find comfortable and familiar to
believe". Consider a guy who keeps an office with 10' deep plush carpets and wears $50,000 suits, people "expect" help to come from someone like that to the extent that they might get fooled after sneering at sincere and true salvation manifest, say, through a guy dressed in a t-shirt and jeans. In contrast, the guy in $50K suit might be desperate for fools so he can pay his lease and credit card off.
