Scientists are human beings and are, like all human beings, susceptible to personal and group biases that may influence how they
interpret evidence. Before original research work is accepted and added to a growing body of scientific understanding, perhaps even contributing to our understanding of an important scientific theory, it must be scrutinized by experts in the field who have no direct connection to the research under review. The main mechanism for doing this is______________.
<em>Before a research can be published, it is subjected to scrutiny by experts that are versed in the same field. The scrutiny ensures that research authors observed the required standards expected in their fields and ensure that personal biases and unwarranted claims are eliminated before the research is published.</em>
