Great to see this excerpt from @helenpearson.bsky.social's new book published in SSIR. The piece highlights the Coalition's partnership with OMB officials & others over 2001-2015, leading to enactment of federal tiered evidence initiatives – “a milestone in the history of evidence-based policy.”🧵

From the standpoint of government efficiency, the recent cancellation of large federal RCTs in education & other areas is counterproductive. These trials are unique in providing highly-credible evidence about what works & what doesn't in government spending (a🧵with concrete examples). 1/3
