This exciting feature allows you, in the comments section, to guess what happened in a randomized trial. One per day all week. Get it while it lasts.
If you want to participate, write if you think the intervention “worked.” That is, measurably raised performance in some way, or not. Other thoughts welcome. Wonk bonus: include effect size in SDs!
I’ll wander back a day later and write the result. No Googling!
Did It Work: A recent randomized experiment had 8 year olds get an hour of reading tutorial a week. Tutors were volunteers from “business.”
(But not from Bain Capital. Nor Solyndra).
