Criteria for Determining Misleading Metrics
- The website for the metric is nontransparent and provides little information about itself such as location, management team and its experience, other company information, and the like.
- The company charges journals for inclusion in the list.
- The values (scores) for most or all of the journals on the list increase each year.
- The company uses Google Scholar as its database for calculating metrics (Google Scholar does not screen for quality and indexes predatory journals).
- The metric uses the term “impact factor” in its name.
- The methodology for calculating the value is contrived, unscientific, or unoriginal.
- The company exists solely for the purpose of earning money from questionable journals that use the gold open-access model. The company charges the journals and assigns them a value, and then the journals use the number to help increase article submissions and therefore revenue. Alternatively, the company exists as a front for an existing publisher and assigns values to that publisher’s journals.
