Street smart vs book smart
You are both right, I have met some very nieve doctors. Yes they are inteligent enough to graduate med school, but in many cases (not all) thats all they know. They have developed a tunnel vision, and anything outside of medicine is forign to them and they come off as unintelligent. I have also met some incredibly inteligent doctors that have amazed me with thier wide thourough (sp) knowledge. This can be applied to any proffesion, it is the person not the proffesion. I have met so called uneducated people, that are very inteligent and have a great understanding of many things. People do not need a piece of paper (diploma) in order to be inteligent, a diploma just shows they have spent the time and effort to learn that perticular field.
I have a sister in-law whom I call the most inteligent stoopid person I know. She has 5 masters degrees in varius fields and is to this day studying for her 6th. However she connot understand freeway signs, she cannot read a map, she cannot have an inteligent conversation on any current affairs, unless it is directly related to one of her areas of study. She is IMHO the poster child for book smart.
Street smart to me is having the understanding of the unwritten laws of the gerneral public, and having a good understanding of its social structure and being able to use that knowledge in a practical way. Wiki's definition is "Street Smart, is a word meaning having shrewd resourcefulness needed to survive in an urban environment." I dont think this can just be generalized as common sence, street smart is much more that your typical common sence. Each persons enviroment and social standing dictates what is common sence, what is common sence for me is much different than it is for an English(UK) person living in a ghetto, or a Tibetan monk.
Relating this back to the original topic; The officer that used the taser has a history of agresivnes and violence, but he ussualy gets away with it. I can, with almost certanty say that he does this much more than is ever reported. In his case he knows what actions he ussualy takes to get the results he wants, this to him is common sence. It is a sick and twisted view, but i believe it is still his views of common sence.
