The account

For decades images resembling faces reportedly formed on the kitchen floor, drawing pilgrims and investigators to the Pereira home.

Analyses found the images were painted/altered; considered a likely hoax or pareidolia enhanced over time.

Faces in a kitchen floor that made a family famous. Evidence of painting, pareidolia and a commercial motive leave little room for anything else.

Explanation	Weight	Why
Undetermined	47%	The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way.
Perception, memory or mind	16%	Pareidolia: the brain readily sees faces in stains, and many “faces” were outlined and named by visitors and investigators rather than seen plainly.
A hoax or fabrication	15%	The faces appeared in a poor family’s house that then drew paying visitors; early analyses for investigators reported pigments and painting marks, journalists Cavanilles and Máñez documented commercial motives, and faces changed or reappeared after floors were dug up and when the family had access. Other analyses found no pigment, but those samples’ handling is unknown.
Something in the surroundings	8%	Damp, salts and oxidation in cement on poorly drained ground make stains that change over time.
A cultural story	7%	The parapsychologist Germán de Argumosa and Spanish TV shaped the story; the claim of bodies under the house added a narrative.
Genuinely anomalous	4%	Supporters cite sealed-floor experiments, but their control was weak and is disputed.
A known natural phenomenon	3%	Ordinary chemistry of concrete, without a face-making process.
