Answer:
The answer is peer review.
Explanation:
Peer review is a process used by scientific journals to assess the qualitiy of the articles that are submitted for publication. The researchers that review an article must be suject-matter experts, since they are the ones that decide whether or not the article should be published. In most journals this peer review process is also blind, meaning that the evaluators don't know the identity of the author of the article; this doesn't only help safeguard against fraud or inaccuracies, but also reduces the bias the reviewer might have.
