New research done by scientists at the University of Aberdeen and the University of California, Berkeley reveals that human vision is up to 15 seconds behind real time, and we function on a “previously unknown visual illusion.” Essentially this delay could be the reason our vision doesn’t make us dizzy or nauseated. “Instead of analyzing every single visual snapshot, we perceive in a given moment an average of what we saw in the past 15 seconds,” the researchers write in The Conversation. “So, by pulling together objects to appear more similar to each other, our brain tricks us into perceiving a stable environment. Living ‘in the past’ can explain why we do not notice subtle changes that occur over time.” Read more about this fascinating find at Popular Mechanics.
