This week, the Freakonomics blog covered research by Stockholm University’s Kimmo Eriksson, which found that including a mathematical equation in the abstract of a research paper made scholars from different fields judge the research to be ‘of higher quality’, even though the equation is unrelated to the work and also complete nonsense.
