Pareidolia effects people (seeing something that isn't there). Often times it's accompanied by confirmation bias. My recent post about confusion over DOT property is an example. The GIS shows XYZ LLC owning an irregular parcel. DOT acquired an easement along the westerly portion 175' parallel with the west line of the parcel leaving a tract east of the east ROW unaffected by the easement. However, although the GIS parcel is correctly labeled as XYZ LLC, some inferred since the east ROW line isn't shown that DOT is the owner (not an easement holder, but owner). It's a bunch of leaps and bounds of GIS interpretation, making the figure into something it's not. Plus the GIS is correct. And it wasn't just one person, many people argued that DOT had some type of rights there. Others were scandalized that the GIS didn't place the easement line crossing the tract (they seldom show easements).
Humans are frustrating beings.
Whenever you analyze property, fight pareidolia.
