Case in Point

Sandra Porter looks into a recent study of why some people never learn from their mistakes. The paper, from a group of German researchers, reports that this type of learning is linked to a dopamine D2 receptor gene polymorphism. Porter, being interested in how people learn from a teacher's perspective, dug a bit deeper and found a problem in the study — the conclusions the researchers draw are based on that polymorphism being located in a dopamine receptor gene, and it's not. "As long as we're talking about learning from mistakes, perhaps someone should suggest to Klein et. al. and the reviewers from Science that they consider learning how to use OMIM," says Porter.
