stupidometry 

The amateur scientific discipline of observing and reporting the level of stupidity exhibited by individuals in response to stimuli. In recent years, the rise of user-generated content online has driven an upsurge in stupidometry. The practitioners of stupidometry and their subjects frequently engage in heated debate in online forums and the comments sections of popular blogs. The impartial observer will often find it difficult to distinguish between practitioners of stupidometry and their subjects, given the subjective and often overlapping nature of these roles.
