How was this "discovered"/developed? I feel that when we are looking at things in real life, focusing on specific objects/shallowing our depth of field doesn't blur the background as drastically as a camera lens.

Our visual system actually does some blurring, but definitely not that drastically. In our fovea there are cells (cones) that are sensitive to high frequency spatial patterns, producing sharp images where we focus. In our retina periphery there are cells (cones) that are only sensitive to low spatial patterns, creating a blurry image in our peripheral vision.

This reminds me of how Lewis Hines, a photographer in the early 1900's, used a shallow Depth o field to create compelling images isolating his subjects highlighting the cruelty in the the child labor industry. His photos convicted the government to later abolish child labor in the United States entirely since each photo told such a compelling story. Full video describing his work can be found here! https://www.youtube.com/watch?v=ddiOJLuu2mo&t=15s
