Remarkable email from John Ioannidis on the new impact ranking
(August 20, 2019)
Warm congratulations by Ioannidis in an email
Dear friends and colleagues
We have just published in PLoS Biology a paper that presents detailed, standardized citation data annotated for scientific field for multiple impact indicators and their composite across science
https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3000384
I want to congratulate you for being in the top 0.01% of scientists based on your impact.
The presented metrics capture not only total citations and h-index, but also co-authorship adjusted impact, and information on impact in papers according to different author positions (single, first, last author). As you know, citation metrics are widely used and misused, and we hope that this effort will allow for a more transparent, more comparable, and less error-prone approach to these metrics. We present very detailed data on all the top-100,000 scientists across science and additional field-adjusted information that can be used to map all 7 million scientists who have published at least 5 papers in their career. across all 22 major fields and all 176 sub-fields. Extensive information is also provided on self-citations and metrics are estimated both with and without self-citations.
The raw data are available for download and unrestricted use at Mendeley Data. I hope you enjoy these databases!
With best wishes for continued success,
John

Conflict of Interest Disclosure Form should not include questions about personal beliefs, activities or life-style
As one of the Associate Editors of Child Development Marinus wrote a letter to the Publication Committee of the SRCD to point out that the non-financial conflict of interests disclosure is an encroachment of some fundamental human rights including freedom of speech.
See the statement here:
Argument against scientific journals’ Non-financial Conflict of Interest
A paragraph from the statement:
Newton believed in astrology, Einstein was a pacifist during war-time, Heidegger was a Nazi, Sartre a Maoist, Darwin has been accused of being an atheist and an anti-feminist, Watson (discoverer of the double helix) a sexist like Trivers, and many other scientists who did great work: whatever we feel about such beliefs, as scientists (authors, reviewers, editors) we should try to evaluate their work as part of World 3 in the sense of Karl Popper, without ties to the person who conducted a study and wrote a paper: not the author but the text and the data reported in the text are the only important object of scrutiny. Otherwise there is a risk of a new kind of McCarthyism of which Linus Pauling like many other scientists did suffer in the fifties, or closer to modern times: a risk of Erdogan-type of persecution experienced by our scientific colleagues in Turkey, dismissed without due process from their tenured positions because of their political ideas.
The good news is that the Publication Committee of the SRCD decided last month to delete this part of the Conflict of Interest Form! The Committee members are gratefully acknowledged for discussing these issues seriously and to decide accordingly.
