Some of these examples seem like they are actually observable:
*the medical harm from gambling and pornography (if by "medical" it is meant either "psychological" or "physical", these are both observable)
*the invisible hand (this one's borderline -- the "invisible hand" itself can't be seen (because it doesn't exist), but its effects can be seen)
*prayer and its effects (definitely prayer, but not necessarility its effects)
*migration patterns of butterflies and birds (definitely observable -- perhaps it is meant the inherent nature of these migrations?)
*deterrence of crime by self-defense (this can be seen both in person and as a whole)
