- Anonymity. This means that the reviews have an increased likelihood of being genuine - the reviewers are more likely to give their true opinion. But, some reviewers can use this negatively and can be unjust and extremely harsh.
- Publication bias. Not all research will get published if it does not aline with what the publishers want to put out. Good/ significant research can face the file drawer problem.
- Burying groundbreaking research. If someone is reviewing a piece of research that conflicts theirs they are likely to be harsh and say that the research is not worthy of being published/ is inappropriate.
