Teaching how to understand underlying causes beyond simply saying "A happened, then B happened. A must have caused B!" I see it endlessly lacking in people around me, and I feel we would be far better off as a society if we taught that at an early age.
The biggest screw up on penn & teller bullshit was this type of mistake. In the sleep episode, they looked at how people try to get a good night sleep and try to sleep more. The implied message of the show is that this is silly and they throw out a statement that people who sleep more tend to die a lot sooner. That's absolutely true that people who sleep more die sooner, but the way the show presented it implies the wrong order of things. People who sleep more die sooner because sleep is one of the ways your body repairs itself; needing to sleep 12 hours a day is a sign that you might be really damn sick. The show implies that it's the other way around - that sleeping too much will make you less healthy.
