These peer reviewers recommend funding the project if it is well designed and appears useful. Improving Research Plans Whether or not a research proposal is funded, reviewers provide constructive criticism. For example, they might improve the experimental design or suggest other possible procedures. Scientists use these peer review comments to improve their research plans. If their research proposal is rejected, they can revise it and try again for funding.
Scientists submit articles to professional journals.
The editor of each journal sends the articles out for peer review, then use these reviews in deciding which articles to publish. Authors commonly revise their articles before publication, based on comments of the peer reviewers and journal editors. Providing Constructive Criticism Peer review helps scientists do their job better by giving them feedback from others. It also helps control the quality of scientific research and publications. But even in professional scientific communities, peer review does not always work perfectly.
