This remarkable image (original here) shows the actual passages of scientists and researchers as they move between articles in scholarly journals. A team at the Los Alamos National laboratory got the idea that mapping scientific research via citation links might be a tad awry because (shock horror) citations have political correctness built into them. So they procured clickstream data covering almost a billion transactions on scholarly journal portals over two years, and produced this elegant map, showing that social sciences and some humanities sit at the densely connected centre of a cartwheel of suspiciously silo-looking scientific disciplines.
Oh, and the original suspicion about citation mapping? The JCR citation database gives a heavy bias towards natural sciences (92.8%) and a passing nod to social sciences (7.2%). What scholars actually read? Natural sciences 41%, social sciences 47%, humanities 8%, interdisciplinary fields 3%.
Thanks to Jack Vinson for this lead.
