Friday the 13th is, apparently, a day of must read articles. This time it’s Steven Pinker’s review of Malcolm Gladwell’s What the Dog Saw: And Other Adventures. Readers who have taken linear algebra will be amused:
He provides misleading definitions of “homology,” “saggital plane” and “power law” and quotes an expert speaking about an “igon value” (that’s eigenvalue, a basic concept in linear algebra). In the spirit of Gladwell, who likes to give portentous names to his aperçus, I will call this the Igon Value Problem: when a writer’s education on a topic consists in interviewing an expert, he is apt to offer generalizations that are banal, obtuse or flat wrong.
