Solipscission (n.)

A cognitive bias in which one perceives their own thoughts, emotions, and inner life as infinitely intricate, layered, and valuable, while reducing the minds of others to simplistic, predictable, or even negligible states. A form of selective solipsism, it creates an illusion of profound self-complexity at the cost of flattening others into caricatures or abstractions. The thoughts and feelings of others, if they exist at all, are simple, forgettable, and mostly wrong—at least, that’s the silent assumption humming beneath so much of human interaction. We cradle our own contradictions like fragile artifacts, while we flatten others into caricatures, mistaking the ease of judgment for insight.

Etymology:

From solipsism (the philosophical belief that only one's own mind is certain to exist) + scission (a cutting or division), indicating a mental severance from the depth of others' subjective realities.

Example Usage:

"His solipscission made him assume that while his fears and contradictions were richly textured, everyone else was just coasting through life with one-dimensional motives."

Egophoria (n.)

A cognitive and emotional bias in which one experiences a heightened sense of their own psychological depth, complexity, and uniqueness while assuming that others are comparatively simple, predictable, or lacking in inner richness. This illusion fosters a self-sustaining euphoria, reinforcing the belief that one's own thoughts and feelings are profound while dismissing the interiority of others as mundane or mechanical.

Etymology:

From ego (self) and euphoria (a state of intense, often illusory, well-being), indicating a self-satisfying distortion of perspective in which one's own mind feels vast while others appear trivial.

Example Usage:

"His egophoria kept him convinced that his emotions were layered symphonies of meaning, while everyone else’s were mere background noise."

Monomnesia (n.)

The quiet, unspoken belief that your own mind is a boundless cosmos—full of swirling contradictions, forgotten corridors, and constellations of meaning—while others’ minds are simple, shallow, and well-mapped. A trick of perspective, like looking at your own life from the inside out and everyone else’s from the outside in, mistaking the masks they present for the whole of who they are. It lingers in the background of daily life, a vague certainty that your struggles are unique, your joys are rare, and your pain is deeper than theirs—until something reminds you that they, too, are lost in their own uncharted worlds.

Etymology:

From mono- (single, alone) and -mnesia (memory, awareness), suggesting a kind of selective awareness that foregrounds one’s own complexity while fading out the richness of others. Like amnesia in reverse—remembering oneself vividly while forgetting that others are just as full of contradictions and unresolved stories.

Example Usage:

"She had lived for years in a state of monomnesia, convinced that she was the protagonist of something vast and unknowable while everyone else was just reading from a script—until she overheard a stranger crying on the phone and suddenly felt the floor drop out from under her."
