What horse advice and baby advice have in common

Have you ever had someone "offer" advice on how to handle a "problem" you are having with YOUR horse? Or more specifically different solutions from different people? This happens a lot with things like trailer loading, for instance to improve your trailer loading you may have heard "heat up his heels", "just offer him a carrot or give him some grain inside", "he's a mans horse, you'll never get him in with treats!", or "you'll have to tranqualize him if you ever want to get him in the trailer". How interesting that most of these "words of advice" are not only conflicting but also at the extreme ends of ways to approach the situation.
Recently I have discovered this phenomenon of seemingly conflicting advice isn't just isolated to the horse world! This realization began to take shape last August with the birth of our wonderful, bright, enquizative, very extroverted son Luke. It seems that the world of youbg children is an area filled with "experts" willing to share their opinion about how things "should" be done. They are so willing that often the meer mention of a young human opens their vault of "useful musts"!
