While it's not technically something I "learned", an idea presented in the interview with Stuart Firestein that I liked was the notion that science created ignorance. I like this idea because it's something I wouldn't really think about. No matter how far back you define the "start" of science, there's always the phenomenon of a discovery that is only known to a small subset of people. Even the simplest concepts of today were at one point seen as hidden knowledge, and even when they became known by a majority of the public, there's always that small percentage that has no idea of the concept. Even today, uncolonized tribes throughout the world have little to no knowledge of most technology and scientific discoveries. While I personally feel odd describing these groups as "ignorant", they do lack awareness to much of modern society. Although there are plenty of other things that could have caused the origin of ignorance, the idea that science is the culprit is one I enjoy!
Thanks for pointing this out Jaida, this was a moment from the video that I originally hadn't thought about too much. While it's definitely true that science and the acquisition of new knowledge by a group of people creates ignorance within groups of people that don't know that knowledge, I think that science also creates ignorance in a different way. This may have been mentioned in some capacity in the interview, but the more we know about a given field, the better we can understand how many more things there are to know that we don't currently know. So in a sense, this is another way that science creates ignorance; the more aware of science we are, the more unexplored and unanswered areas we're exposed to, making us feel more even ignorant than when we started.
