Derpatology 

Is the observation that common socially acceptable behaviors, reactionary standards of dispute resolution, interests in higher learning and "self betterment" are on the sharp decline in America and some other country/states . Many Derpatologists agree; with the constant incline of the state of "Derp", lower I.Q's will follow at an equal or sharply worsening rate.
Very un-common to use in sentence structure, since it's not science just rhetoric at this point. But as a rudimentary example:

"Got my B.S. in Sociology. Served four years in Peace Core. Became a parole officer. Yada yada yada, later found my way into derpatology."

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
