A clear and compelling read on IES. I hope policymakers pay attention to this. There is a very strong bipartisan case to be made for continuing to fund the development, evaluation, and syntheses of evaluations of educational programs and policies.
Helping teachers learn what works in the classroom − and what doesn’t − will get a lot harder without the Department of Education’s Institute of Education Sciences via @ConversationUS.

I suspect economists are over-incentivized to produce sexy findings (like social psychologists, especially 10-15 years ago) and very much under-incentivized to preregister and replicate.

Underpowered designs and p hacking in econ should be treated as a scandal. The field has otherwise does a pretty nice job enforcing high methodological standards for the social sciences. But if a field's norms produce this pattern, they're probably the wrong norms.
6/ P-Hacking: They then manually code 150 JMPs to document the relationship between p-hacking and academic placement. JMCs with marginally significant results were more likely to secure academic jobs, especially during the job market of the COVID-19 pandemic.

These are big effects, and I bet they will receive less attention than they deserve.

Heuristic: If >50% of the cost of your study goes to generating exogenous variation and then you present your analysis in a way that focuses on *other* variation, you might be self-deceiving.
3/ The study states that it found "minimal differences" in outcomes among the 3 groups. For example, the Project's website features this graph showing that housing stability for groups A & B was very similar to C at the 10-month follow-up ("timepoint 3" - dark green bar):
