How would you handle a bibliographic search to minimize bias in a seminar literature review?

• A. Use predefined inclusion/exclusion criteria, search multiple databases, screen abstracts consistently, document decisions, and consider both supporting and conflicting evidence.
• B. Rely on anecdotal notes.
• C. Ignore conflicting evidence.
• D. Use only one database.

Answer: (A)

Minimizing bias in a seminar literature review comes from using a systematic, transparent search process that others can reproduce. Start with predefined inclusion and exclusion criteria so every study is judged by the same rules—things like the population or topic of interest, study design, publication year, and language. This helps prevent cherry-picking and keeps the scope consistent.

Searching multiple databases broadens coverage beyond a single source and reduces the risk that important research is missed due to database gaps or indexing differences. It’s also important to use a well-documented screening process for abstracts and, ideally, full-text articles, with a clear checklist or criteria. Recording decisions, keeping notes on why each study was included or excluded, and, if possible, having a second reviewer to check decisions creates an trail that enhances transparency and allows others to understand or replicate the approach.

Equally critical is considering both supporting and conflicting evidence. This guards against confirmation bias and leads to a balanced synthesis rather than a one-sided view. Including strategies like searching for synonyms and controlled vocabulary, and potentially tracing citations from key found articles, further strengthens the search.

Relying on anecdotal notes, ignoring conflicting evidence, or using only one database all introduce biases and reduce the credibility and completeness of the review.
