text: While mistakes and misunderstanding might have similar definitions, in this context they are two completely different things. First of all, mistakes are when the advice-giver confuses two similar things and gives the wrong advice. A good example of this is when you are talking about a level on a video game you are having trouble with, and your friend, thinking about a similar level, gives you incorrect advice. Now you are going to have a harder time beating the level because your friend told you about a different level. However, this could have all been avoided if you had asked three or four more people for advice on the level. The more similar iterations people give you, the better the chance that the information your getting is true.
