"I’m not trying to bulk up the JIF of PNAS ... what I’ve written here is considered 'Editorial ephemera' and ... isn’t even included in the JIF calculation" Not correct; JIF numerator also includes citations to editorials

Replying to @DalmeetS @C0PE and 7 others
Relevant article. Thanks for citing. In Mishra 2018, we go beyond replicating the King paper and study factors which influence self-citation. Your mention appears influenced by our title & abstract v/s detailed conclusions in our work. Also no DOI.

I'm not convinced of the value of detailed researcher-level self-citation statistics; I don't think this will improve the way citation metrics are used; what is needed is a careful discussion about suitable ways of using biliometric data in expert-based evaluations of researchers

We need to start a discussion on why we are banging the rankings' drum instead of telling the world what we are doing in the field of diversity, open science & scholarship and public engagement. And why they do not go together.

Grab your seat for a slightly smaller and more intimate annual meeting “The strategy one” and help shape Crossref’s future priorities in Amsterdam 13-14 November. There won’t be talks (so no livestreaming) but roundtable workshop-style discussion

Why not publicly share the responses you sent to the EiC of TSE? I would be very interested to read them

I believe it would be better to have a discussion in public rather than behind the closed doors of the peer review system; you generated a lot of public attention for your work, which is perfectly ok, but you should then also be open to having further discussion in public

Excellent, thoughtful commentary on the balance points among three goals in metrics: technical sophistication, clear interpretation, and transparency.

More accurate metrics do not necessarily lead to improved evaluation; especially when metrics are used at the individual researcher level, contextualization, transparency and openness are more important than accuracy
