The problem is that this system also leads us to ignore certain anomalies. If a scene resembles a normal situation—for example, people sitting and smiling—our brain assumes that everything is consistent and doesn’t necessarily investigate further.
That is precisely why many people do not immediately see the error in this image.
The mistake that almost no one sees at first glance
The photo shows three women who appear to be sitting, smiling, in a perfectly normal position. Two of them have their legs crossed; the posture is natural, and nothing seems out of place at first glance. Yet, there is one detail that should immediately draw attention, but which most people miss.
The illusion of the invisible chair
The real question isn’t about their clothes or the background, but simply about what they’re sitting on. In reality, nothing at all: there’s no chair, no bench, no visible support. The image has been altered to create an illusion, and our brains automatically imagined an invisible chair because the position of the bodies corresponds to someone sitting. Our minds thus complete the image without us even realizing it.
