The 'Uncanny Valley' meme draws from the psychological theory that humanoid objects which appear almost human but fail to be perfectly lifelike trigger feelings of eeriness and repulsion. On social media, this concept evolved into the 'Mr. Incredible Becoming Uncanny' format, where an initially joyful image transforms into progressively darker, distorted, and more realistic versions as the caption describes increasingly dire scenarios. It serves as a visual shorthand for escalating dread, existential horror, or the realization of an unsettling truth. The meme thrives on its ability to turn mundane situations into disturbing digital art using eerie audio and visual distortions.
