peer review is the process after research has been conducted to asess the quality of it before it is published in a journal
peer reviews are carried by other psychologist who weren't involved in the study but are in a similar field
peer reviews judge the validity, originality and quality of the research before publication
peer reviews judge the significance of the research in a wider context
peer reviews assess whether the following is appropriate: research methods, hypotheses, stats tests used, conclusion drawn
peer reviews allows reviews to share whether they believe if the research can be published in the original form or if it needs to altered or evenif the whole research needs to be withdrawn
anonymity is avoided during peer reviews so that they can't be overly critical to sabotage their rivals possible funding
peer reviews can sometimes hold publication bias because the journal may find that the research isn't headline grabbing enough, this will mean that the journal will be creating a false impression of the current state of psychology
peer reviews can also bury ground breaking research as if it goes against a mainstream theory, reviews may be critical of it and therefore slow down the rate of change in psychology
