John G. Halstead comments on Are education interventions as cost effective as the top health interventions? Five separate lines of evidence for the income effects of better education [Founders Pledge]

[John G. Halstead]

I don’t think deworming is classed as an education intervention by GiveWell. The rationale for deworming is that it supposedly increases long-term income. But GiveWell is unsure about the mechanism by which this happens. The follow up studies to the Miguel and Kremer RCT (the only study used by GiveWell to assess deworming) find “little to no impacts on education”. The initial RCT found no effect on test scores.
