Ethical Considerations and Gaming the System Concerns about manipulation have led to scrutiny of practices such as coercive citation, where editors request references to their own articles to artificially inflate numbers.

Funding committees and promotion panels often use these metrics as a shorthand for research quality, creating a feedback loop where influential journals attract more prestigious submissions. How the Impact Factor Is Calculated The core formula divides the number of citations in the current year to items published in the previous two years by the total number of citable items published in those same two years.

Altmetrics track mentions in news, policy documents, and social media to capture immediate societal reach, while article-level metrics provide download and citation data for individual papers. This specific timeframe creates a rolling window that aims to reflect recent influence, though the choice of a two-year denominator is often debated within the scholarly community.
