Amazing it's actually a decent study that passes smell tests. 15,000 students used, a success that is based on high rates (20 of 24), and a twenty % difference

Amazing it's actually a decent study that passes smell tests. 15,000 students used, a success that is based on high rates (20 of 24), and a twenty % difference between groups. I hope they follow up to measure how well information is retained, and maybe see if the two groups share knowledge (control going up).
