It takes several months to years for a researcher to publish a paper. A commonly cited reason for delayed publication is that the peer reviewers often recommend that additional experiments be performed. While reviewer-suggested experiments might be intended to ensure that authors’ claims are supported by substantial evidence, such requests lead to a prolonged peer review process. This not only keeps good science away from the public but also increases the cost of labs since additional experiments need to be conducted. Do reviewer-suggested experiments really help in improving the research data or are the suggestions made indiscriminately? Can journal editors play a role in ensuring that peer review is conducted responsibly? Read the article that discusses these issues in depth.
