:No, you should be bold and make any changes that you feel will improve the article  of course you are welcome to discuss anything you have doubts about.  The two things to bear in mind are (1) our articles should be neutral, that is, they should present facts and not advocate for points of view; (2) Wikipedia differs from academia in that the preference here is to minimize the number of references, because huge numbers of refs make an article hard to maintain.  In practice that means relying whenever possible on review papers rather than the primary research literature  see WP:MEDRS for more information.  In short, feel free to ask questions but also feel free to be bold.
