Most college professors are very tempered when they teach and they are very careful not to say anything that is incorrect.
Academia prides itself on being accurate in the information they depart to the students and yet, every once in a while you will find a professor that makes the mistake or says something about an industry or subject matter that you know a lot about.
Sometimes, you know more about this subject than they do and usually this is a side subject that the professor went off on a tangent to make a point.
Now, it is best to let the professor go when they screw up and not make a scene.
But if you find the professor doing this all the time and you're getting sick and tired of it, there is a way to ask a question of the professor, which will help him or her rethink their views and improve in using that example in the class and prevent them from damaging future students with false information.
Let me explain how I do it and try to diffuse the situation without making the professor look like a stupid person.
Let's say that a professor says something like; "everyone knows capitalism is dead, especially after this latest global financial crisis.
" Rather than attacking the obvious mistake and attacking his socialist mindset with the "capitalism is dead" comment, you might ask; "is it your belief that even the folks at the Ayn Rand Institute "know that capitalism is dead" or would you say there're still some holdouts, that do not realize this yet?" The professor will have no choice and he will have to backtrack on his statement and say something like; "good point, not everyone knows that capitalism is dead, but most people do.
" Then you can ask another question; "do you feel that most people fail to realize that the United States of America is the greatest nation ever created in the first history of mankind or that it has climbed to the top of its food chain because of capitalism?" In doing as you will find that the professor will either have to move the class forward and forget about that statement or retract it altogether or will have to defend his position and since he cannot defend his position that capitalism is dead, because it obviously isn't and all he will do is dig himself a bigger and deeper hole.
I recommend that you tape-record on a digital recorder everything the professor said and put it onto a YouTube video with his name on it to make it look like the socialist he is.
That's how I do it, and it works every time.
Take no prisioners.
