Evaluation of peer reviews
+ can establish the validity of scientific research prior to publishing
+ protects the good name of psychology, ensuring that the public have confidence in it
+ confidentiality of peer reviewers allows them to be honest and objective in their assessment
_ slow and expensive, using peers to reviews adds time to publishing reviewers with them also needing to be paid
_ difficult to find experts which means poor research can be passed as they don't fully understand
_ open to bias as peers can make judgements on research based on their own perceptions and experience
