Biases arise if people are allowed to cite other papers even when the publications are made anonymous. The importance of a paper can be estimated from their citations. For example, an important work cites another ground-breaking work. Besides, novel research idea and topic is rare and serves as a signature to the authors and their affiliations. Because researchers often verbally share their research results with others (through the internet), every people will recognize them and their works finally.<p>My feeling is that as long as the whole open system makes scientific progress, and suppresses malicious or false scientific results, it is fine.
