Great virtues are attributed to them, but also some problems have been reported evidencing the weaknesses of such system. This article makes a synthesis of the most important virtues, critics and possible solution strategies reported by scientific literature in recent years. These inputs are expected to be useful for the editors, peers and authors of scientific journals and serve as a guide to those interested in continuing with the research work required to strengthen this evaluation system.esCorporación Universitaria LasallistaUniversidad Pontificia BolivarianaInstitución Universitaria Colegio Mayor de AntioquiaPublicación científicaRevisión por paresBioéticaÉtica científicaArticle
