Moreover, general statements on the effectiveness of learning methods are not credible—learning results depend on too many variables to enable such precision. Unfortunately, this bogus information has been floating around our field for decades, crafted by many different authors and presented in many different configurations, including bastardizations of Dale’s Cone.

After reading the cited article several times and not seeing the graph—nor the numbers on the graph—I got suspicious and got in touch with the first author of the cited study, Dr. Michelene Chi of the University of Pittsburgh (who is, by the way, one of the world’s leading authorities on expertise). She said this about the graph:

“I don’t recognize this graph at all. So the citation is definitely wrong; since it’s not my graph.”
