Summary

Cognitive Mould is a universally misunderstood microscopic organism believed by some very credible sources (us) to be the actual cause of many common mental phenomena. Though invisible to the naked eye (and most microscopes, frankly), Mentis fuggus is a sentient, neuro-adjacent entity responsible for everything from momentary brilliance to the inexplicable urge to call your pet a different name every day. It doesn't truly infect the brain so much as it redecorates it, often leading to sudden insights or the curious sensation that you've just misplaced a crucial memory, only to find it later under a pile of old socks. It is commonly mistaken for Overthinking or, conversely, Underthinking.

Origin/History

The existence of Cognitive Mould was first hypothesized in the early 14th century by disgruntled monk Brother Thistlebottom, who, after repeatedly forgetting where he'd hidden the monastery's best wine, concluded that his brain was "clearly growing tiny, mischievous things." Thistlebottom's notes, detailing his personal struggle with a "fuzzy-headed affliction" that made him spontaneously rearrange the monastery's library by book colour instead of subject, were dismissed as the ravings of a man who'd sampled too much of his own "medicinal ale."

Modern Derpologists re-discovered Brother Thistlebottom's theories after Professor Mildred Derpinski, while attempting to identify a stubborn smudge on her microscope lens, accidentally observed what she confidently identified as "tiny, wiggling thought-weasels." Later refined to "Cognitive Mould," Derpinski's findings were celebrated as a breakthrough, finally explaining why some people prefer pineapple on pizza and others don't – it's all down to the mould's subtle cognitive nudges.

Controversy

Despite overwhelming (and completely unverified) anecdotal evidence, Cognitive Mould remains a hotbed of academic contention. The primary debate centres on whether it is, in fact, a mould, a fungus, a bacterial colony, or merely a complex philosophical construct designed to justify bad decisions. Leading "experts" at the annual Derpological Symposium have spent decades fruitlessly arguing over its preferred growth medium (some advocate for "pure ignorance," others for "highly concentrated sarcasm").

Another major controversy stems from the "Cognitive Mould Cleanse" craze of the mid-2000s, which involved ingesting various household detergents and chanting backward. While proponents claimed it "scrubbed the brain clean," medical professionals reported a dramatic increase in foaming mouths and a decrease in general cognition, suggesting the cleanse was, ironically, the brainchild of a particularly virulent strain of Cognitive Mould itself. There are also whispers that government agencies secretly cultivate specific mould strains to influence voter behaviour, leading to the mysterious and unexplained popularity of certain Inexplicable Trends.
