Sometimes the impact factor outshines the H index
2008

Impact of Journal Quality vs. Author Quality

Sample size: 97 Commentary Evidence: moderate

Author Information

Author(s): Hönekopp Johannes, Kleber Janet

Hypothesis

The H index is unsuitable for predicting the future success of an article compared to the journal's impact factor.

Conclusion

The study found that the journal's impact factor is a better predictor of an article's future citations than the author's H index.

Supporting Evidence

  • The study analyzed 97 articles by 29 board members of Retrovirology.
  • Log(IF) was a significant predictor of citation frequency.
  • The H index did not predict citation frequency.
  • Reviewers are biased in favor of prestigious authors.

Takeaway

This study shows that when deciding which articles to read, it's better to look at the journal's reputation rather than the author's past work.

Methodology

The study used stepwise linear regression to analyze citation frequencies based on the H index and impact factor.

Potential Biases

Reviewers may be biased towards prestigious authors, which could affect the peer-review process.

Limitations

The predictive power of the impact factor was found to be surprisingly small.

Participant Demographics

Participants were editorial board members of the journal Retrovirology.
