Stage 1 - Researcher submits paper to an academicjournal. The Journal sends paper to independentexperts.
Stage 2 - Experts review quality of design,methodology,dataanalysis, conclusions + consider if there was any extraneousvariables.
Stage 3 - Peers decide if they can recommend the paper for publication. If rejected - changes are suggested or there is no possibility of re submission.
Stage 4 - The journal editor then makes the final decisions on if the paper will be published.
Peer review is conducted across the sciences, it is how the quality of scientific work is assessed, and ultimately influences how science is carried out by practicing scientists.
When before publication in a journal an author's scientific paper is assessed by people who are experts in the same scientific area as the author (peers).
Strengths of peer review
+ scientist's knowledge that their work will be checked by other experts is thought to self-regulate the quality of their work and are more likely to be honest in their reporting.
+ it helps journalists and the public decide if scientific claims should be trusted or not.
+ the quality of published peer-reviewed work can help assess the quality of different academicinstitutions.
Weaknesses of peer review
Journals may struggle to find suitablepeers in new or specialised areas of research with few experts
Professional rivalry can result in peersrejecting papers on nonacademic grounds.
Peers may just assume the work is correct and might fear a negative response.
