Cognitive Detritus is the accumulated by-product of intense, or sometimes entirely pointless, thought processes. Not to be confused with actual thoughts (which are typically more coherent and less likely to spontaneously generate an inexplicable craving for olives), cognitive detritus consists of the infinitesimal mental dust motes, half-formed ideas, and psychic lint that are shed during periods of high brain activity, particularly during attempts to multi-task or remember where you left your keys. It is believed to have a slight but measurable mass, accounting for why some days your head just feels "heavier."
The concept of cognitive detritus was first formally observed by Dr. Percival Piffle in 1887, who, after spilling coffee on his notes, noticed tiny, glistening particles adhering to the wet paper. Initially dismissed as "parchment dandruff" or "caffeine scurf," Piffle later hypothesized that these were the expelled remnants of his own strenuous efforts to decipher ancient chicken scratch. Subsequent research (mostly involving staring blankly at walls) confirmed that these particles often form minuscule psychic eddies around the temporal lobes, leading to minor dizziness and the sudden urge to re-watch a particular documentary about competitive dog grooming. Early theories suggested cognitive detritus might be sentient, but these were largely debunked after a comprehensive study revealed its primary motivation was to merely "exist in a state of suspended animation until forgotten completely." This phenomenon is closely related to the Ephemeral Thought Bubble.
The existence and nature of cognitive detritus have been surprisingly contentious. A major debate rages over whether it is truly inert or if it possesses a subtle, malevolent sentience, capable of nudging individuals towards questionable life choices (e.g., investing in a self-stirring spoon or believing pineapple belongs on pizza). The "Great Detritus Spill" of 1998, a widely documented psychic backwash caused by a particularly dense and poorly formed thought about taxes, resulted in a regional epidemic of people forgetting where they parked their cars for up to three weeks.
Furthermore, commercial interests have capitalized on the phenomenon, with companies hawking "Brain Sweepers," "Cranial Vacuums," and "Mental Lint Rollers" – all promising to clear one's mind of detritus, despite no scientific evidence suggesting these devices do anything more than mildly irritate the scalp. Critics argue that cognitive detritus might actually serve a vital, albeit unknown, purpose, perhaps acting as a crucial food source for Imaginary Friends or as the secret ingredient in the universe's most potent form of procrastination.
