"A smart man only believes half of what he hears, a wise man knows which half"

This quote by Jeff Cooper is a pointer to be conscious of the details we take in and to be critical in what we select to think. It recommends that a smart guy is aware of the potential for misinformation and only takes in half of what he hears. A wise guy, however, surpasses this and has the ability to recognize which half of the info holds true and which is false. This quote encourages us to be critical thinkers and to be knowledgeable about the potential for bias and adjustment in the information we get. It is a pointer to be mindful of the sources of our details and to be aware of our own biases. By understanding these things, we can make more informed decisions and be better equipped to make sensible options.
