It’s plausible that some of these are as cost-effective as the GW top charities, but perhaps not that they are as cost-effective on average, or in expectation.
I agree, for most values of “plausible”. Otherwise, it would imply TLYCS is catching many GiveWell-tier charities GiveWell either missed or turned down, which is unlikely given their much smaller research capacity. But all TLYCS charities are in the category “things I could imagine turning out to be worthy of support from donors in EA with particular values, if more evidence arose” (which wouldn’t be the case for, say, an art museum).
