Do you think it always does? It always seems to in my case.
As far as whether it should or not, I'm torn. Without people passionately advocating certain theories, I'm not sure the scientific community would ever become motivated enough to run the tests.
You threw me off with the word "belief". I don't see valid theories as "beliefs". "Beliefs" shouldn't be taught in science class. That was my approach.
However, in a way, I think you are right. A proffessor should care about a subject so as to ensue they cover all aspects, not just a brief summation.
I've been in classes with a lot of teachers and professors, and I don't think I can say that any of them really taught without personal bias.
I was referring more to the extreme, where it would hinder the learning process. Everyone should have an even keel regarding rational thought. Even a staunch atheist shouldn't say how religion is so fucked up, or put it down in such a manner as to put off his students, because religion does SOME good for SOME people. That's the kind of personal bias I was talking about.
I've heard arguments from religious people that this can be a good thing (you know, if I don't teach my kid about Jesus while he's young, he won't grow up in the truth).
Isn't that how religion operates though? Look what happens to religious people when they open their mind: they turn into atheists.
And, I'm sorry to say, I have met many scientists who would probably likewise assert that teaching their viewpoint is the only sensible way to run a classroom.
You know damn well how hard it is to discuss things with people who only see things one way, so why not get kids thinking about all aspects early on?
As a current grad student, most of my training has so far focused on how to convince people that I'm right about something, and the part about how to actually be right about something has been pretty much left to me to figure out on my own.
I'm not a student, and I dropped out of high school (I regret it every day). My dealings with people here and abroad, in the workplace and in personal life have taught me that two heads are better than one. No one person will ever have the right answer to everything. Why spend all your time trying to prove you are right? You will learn more if you try to gain insight on other peoples thoughts and how other people think about things. Very few tasks are best completed solo, teamwork is essential.
There have been MANY times where I had an idea, only to spout it off here, thinking I was completely right and sure of it,... and see another posters POV and have it change my way of thinking.
Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people

For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
