In individuals everything is automatically interpreted in terms of existing belief. If something is so anomalous as to not be perceived in terms of our beliefs we ask others, experts, or colleagues which is exactly what happened when the thermal anomaly was discovered; they asked for Egyptologists to provide hypotheses as to its existence.
The real problem with beliefs though isn't that they determine our perception. THEY DETERMINE OUR ACTIONS! Since all the fundamental questions about the pyramid were "known fact" none of these were being challenged or examined. Even new evidence was simply seen in terms of the old beliefs and like a frog that sits too long on a warming skillet their beliefs had become out of phase with the totality of the evidence. They were getting burned and never noticed.
Since actions are determined by belief one simply naturally works to confirm those beliefs. Over time we each become what we believe. We are as incapable of change in most instances as the cooked frog. Most people, including scientists, will go to their graves without ever recognizing new theory or the overwhelming support for it. Indeed, there's probably little difference between Einstein and any splitter from the dark ages.
A great poet once said; 'You are locked into your suffering and your pleasures are the seal.". It is the human condition, but I believe it hasn't always been so. There's no going back but understanding this might ease some suffering going forward.
