Its not about being dinguses, its about teaching people who are 20+ years old to think before they speak. That old mantra "there are no stupid questions" is WRONG. There are stupid questions, and the people who ask them are considered stupid.
How many times have we ALL sat in an O-Chem class and some ******* premed raises their had and LITERALLY repeats the same exact thing the prof just said only in question form. FOR NO APPARENT REASON. Or they ask some stupid BASIC question that if they had thought about it for 2 seconds they could have known the answer themselves. Or hell even looked it up in the book. God, especially in Office hours - the number of stupid questions people come up with in office hours is ABSOLUTELY astounding.
Honestly, I sometimes think the premed lifestyle where premeds are working to suck up to professors to get letters of rec. is why this happens. They get so used to asking stupid questions - just so they have something to open their mouth about - that they start thinking stupid questions are ok.
They're not. They make you look stupid. When a question comes to your head, think about it for at least 30 seconds, determine if its not somethign you can google or look up in the book, and ONLY THEN should you ask it. We are all at least 20 years old, we've been in school for ages and we should know better than asking a question that could have been solved with a dictionary.
