Different Bayesian priors lead to different subjective interpretations of the same sensory input, as demonstrated by the perception of '#TheDress'.

“Okay, so then people ask, "Well, is there anything real? What is the real color?" No, there is no real color. What there is are photons that are from the sun that strike the two-dimensional surface of the dress that get absorbed by my photoreceptors, that then get processed, and they get evaluated in one way in our brain, so we see it as white and gold, and get valued differently in a different brain because we all have different priors.”
