Most churches would be uncomfortable with that much individual freedom of thought. This conflict over who should be in control of individual lives would interfere with many churches advocating self-help psychology to improve your life. Schools One would think that schools are the perfect place to give away all the useful knowledge science has found. But that doesn't happen. In the case of self-help, there are many reasons.
Schools fear having even more responsibilities, especially with very limited budgets.
School schedules are filled and other disciplines don't want self-help psychology to take part of their class time. Neither psychology nor education has prepared teachers to handle a class in which students learn to direct and change their lives. As mentioned above, there isn't even a comprehensive textbook that all students could use to plan self-improvement projects. Our public education system can't be prepared to teach useful psychology at the jr high and high school level until 2020, at the earliest. University psychology professors yearn to publish research with the brightest graduate students, but most would abhor intimately teaching personally useful courses to ordinary undergraduates.
