After our own testing, to ensure that all is done well and the information we have obtained is valid, it undergoes another rigorous process known as peer review before our data are published in a reputable scientific journal. In peer review, anywhere from a half dozen to a dozen scientists who are experts in the same field review the information in the study. This ensures that testing or experimenting and the analysis have been done correctly and sufficiently. Peer reviewers reject papers more times than they accept them for publication, and most of the time, even if a paper is accepted, it is accepted only if the author is willing to make corrections suggested by the reviewers.
