I am a PhD student after the mid stage. I come to know a very strange thing about academia that acceptance is a bad thing. Let me define acceptance, many time i hear the statement of other collegues including my supervisor, research fellows etc. What happens that I always tried to accept their arguments even if they are wrong. If they are wrong, Instead of being harsh, I try to accept their argument then explain my argument. The problem arises due to this is that many times these people try to manuplate me. Like in TA work I listen to the person who comes to me (student) no as I am listening to him he starts thinking that I have not understood his statement, which is not always the case.
In short I accept others mistake, errors etc, but when it comes to me that if i am wrong other people show their very rude behaviour. I don't Is this common in academia? What kind of person I should become the one who point out others mistake and make them realise that they are wrong or the one who accept others wrong things in a positive way?
