Metascience Working Group

This recently launched:

The Metascience Working Group (MSWG) is a forum and coordination platform for academics and policy practitioners to contribute and draw on key insights that could inform the design and evaluation of science funding programs.

They are accepting idea submissions:

We need your help! Scientific breakthroughs often come from unexpected places, and we suspect the same is true of metascientific breakthroughs. If you are interested in contributing an idea or proposal for a new metascientific experiment, we would love to hear from you. Our team can help provide input on your idea and share it with relevant policymakers and philanthropic science funders.

For a broader context, see this article: Developing the science of science - Works in Progress

It would be nice if some of the ideas from A Vision of Metascience (Article) get put into practice
