Why are journal impact factors problematic?

Statistically, there is also a problem with JIFs because a high impact factor may be derived from a few highly cited papers. Most papers do not get many citations, but are still regarded as influential because the overall impact of certain individual papers in the journal is high.

Why is impact factor flawed?

JIF is an aggregate value calculated based on citations of the individual articles in a journal. But because citation counts are highly variable among articles, JIF cannot tell us anything about the quality of any given individual article.

What are the disadvantages of impact factor?

Why the impact factor of journals should not be used for evaluating research?

In other words, the most cited half of the arti- cles are cited, on average, 10 times as often as the least cited half. Assigning the same score (the journal impact factor) to all articles masks this tremendous difference—which is the exact opposite of what an evaluation is meant to achieve.

What is the difference between impact factor and journal impact factor?

The journal Impact Factor is the average number of times articles from the journal published in the past two years have been cited in the JCR year.
