Language Log: Scrupulously avoiding sigma:

It’s not a new idea to base legal, educational, or social prescriptions on scientific findings. It’s not a bad idea, either, unless such arguments are based on bad science, or on good science badly applied. But I’m afraid that in today’s educational policy debates — and not just about segregation of the sexes — the density of bad or misrepresented science is high and rising. In self-defense, our society needs to persuade people like Anastasia Rubis that standard deviations should not be so scrupulously avoided.
