Disadvantages of literature review in a research project

A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24]. In many cases, reviewers of the literature will have published studies relevant to the review they are writing.

This could create a conflict of interest: how can reviewers report objectively on their own work [25]? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution if any to a field when reviewing it. In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial.

If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings.

How to write a good literature review article?

In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors. Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published.

This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile.

Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society. Inevitably, new papers on the reviewed topic including independently written literature reviews will appear from all quarters after the review has been published, so that there may soon be the need for an updated review.

But this is the nature of science [27] — [32]. I wish everybody good luck with writing a review of the literature. Many thanks to M. Barbosa, K. Dehnen-Schmutz, T.

Rule 1: Define a Topic and Audience How to choose which topic to review? The topic must at least be: interesting to you ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary , an important aspect of the field so that many readers will be interested in the review and there will be enough material to write it , and a well-defined issue otherwise you could potentially include thousands of publications, which would make the review unhelpful.
