The positive case for suppression: A guest post from the editor in chief of Clarivate’s Web of Science

This is an invited guest post related to news about two suppression reversals announced today by Clarivate. The research process is rarely straightforward. There are a myriad of ways in which it can go wrong, from the inception of a hypothesis that goes on to be disproved, to failed experiments and rejected manuscripts, hopefully ending … Continue reading The positive case for suppression: A guest post from the editor in chief of Clarivate’s Web of Science

“Stunned, very confused”: Two more journals push back against Impact Factor suppression

At least two more journals are fighting decisions by Clarivate — the company behind the Impact Factor — to suppress them from the 2019 list of journals assigned a metric that many rightly or wrongly consider career-making. In a letter to the editorial board of Body Image, an Elsevier journal that was one of 33 … Continue reading “Stunned, very confused”: Two more journals push back against Impact Factor suppression

Seventeen journals lose impact factors for suspected citation manipulation

Clarivate, the company that calculates Journal Impact Factors based on citations to articles, didn’t publish the metric for 17 journals this year due to suspected citation manipulation. That’s a substantial increase from last year, when only four were excluded.  The increase is, in part, case of rising tides lifting (sinking?) all boats: In its 2024 … Continue reading Seventeen journals lose impact factors for suspected citation manipulation

Ten journals denied 2020 Impact Factors because of excessive self-citation or “citation stacking”

Clarivate, the company behind the Impact Factor, a closely watched — and controversial — metric, is calling out more than 20 journals for unusual citation patterns. The 21 journals — 10 of which were suppressed, meaning they will not receive an Impact Factor in 2020, and 11 of which received an expression of concern — … Continue reading Ten journals denied 2020 Impact Factors because of excessive self-citation or “citation stacking”

Major indexing service rejects appeals by two suppressed journals

Journals hoping that Clarivate Analytics — the company behind the Impact Factor — would reverse their decision to suppress their titles from the closely watched metric are batting .500. In July, as we reported, Clarivate suppressed 33 journals from its Journal Citation Reports (JCR), which means they will not have a 2019 Impact Factor, because … Continue reading Major indexing service rejects appeals by two suppressed journals

Major indexing service reverses decision to suppress two journals from closely followed metric

Following pushback from members of the taxonomy community, Clarivate Analytics, the company behind the Impact Factor, has reversed its decision to suppress two journals from receiving those scores this year.

Indexer “obviously made a mistake” in sanctioning taxonomy journal, says editor

Zoologists are up in arms that a leading taxonomy journal is being called out for excessive self-citation and being denied an Impact Factor. Last week, Clarivate announced that it was suppressing 33 journals from its Journal Citation Report, which would mean no Impact Factor for those journals, because of high levels of self-citation that distorted … Continue reading Indexer “obviously made a mistake” in sanctioning taxonomy journal, says editor

Major indexing service sounds alarm on self-citations by nearly 50 journals

More than 70% of the citations in one journal were to other papers in that journal. Another published a single paper that cited nearly 200 other articles in the journal. Now, Clarivate, the company behind the Impact Factor, is taking steps to fight such behavior, suppressing 33 journals from their indexing service and subjecting 15 … Continue reading Major indexing service sounds alarm on self-citations by nearly 50 journals

A group of editors of journals focused on the history of economics has gone public to urge Clarivate Analytics, which publishes a highly influential ranking of journals, to reconsider its decision to drop the titles from this year’s index.
