Bias Quote by Sam Kean
““This hinted at something that no one had ever suspected -- that the brain tracks moving things more easily that still things. We have a built-in bias toward detecting action. Why? Because it's probably more critical for animals to spot moving things (predators, prey, falling trees) than static things, which can wait. In fact, our vision is so biased toward movement that we don't technically see stationary objects at all. To see something stationary, our brains have to scribble our eyes subtly over its surface. Experiments have even proven that if you artificially stabilize an image on the retina with a combination of special contact lenses and microelectronics, the image will vanish.””
About This Quote
Source Book: The Tale of the Dying Earth, Sam Kean, 2021
The brain is wired to prioritize moving stimuli because detecting motion was essential for survival, making static objects harder to perceive without eye movement.
In simple terms: Our brains notice motion more than stillness.

A Different Perspective
Static objects can be missed without deliberate scanning, limiting awareness.
![“[Animals] do not so much act as be put into action, and that objects make an impression on their senses such that it is necessary for them to follow it just as it is necessary for the wheels of a clock to follow the weights and the spring that pulls them.” quote by Marin Mersenne](https://sms4smile.com/quotes/img-quotes/962/marin-mersenne-72883_action_animals-do-not-so-much-act-as-be-put-int_2668251.jpg)
