Insular policy feedback: Why reforming metrics alone may not be enough Metric-driven research systems persist because governance structures often matter more than metrics themselves.

Across the social sciences, half of research doesn’t replicate Ambitious effort tested whether more than 100 papers held up on multiple types of “repeatability” tests

The credibility of scientific journal articles might be bolstered if they carried a score capturing their rigor, such as whether the findings could be replicated. But constructing a telltale indicator of replicability remains a challenge. #openscience @science.org www.science.org/content/arti...

CERN to host Europe’s flagship open-access publishing platform Open Research Europe | NWO The European Organization for Nuclear Research (CERN) has been selected to host a new phase of Open Research Europe (ORE), supported by the European Commission and a new funding consortium of European national funding agencies and research organizations. NWO recently joined this consortium.

Last week, the new phase for ORE was officially announced. The consortium backing the net platform is a unique collaboration between 16 funders and institutions, and @cern.bsky.social as the operating organization.

I’m proud to say that the Dutch Research Council is a member. Read our news item:👇🏽
