The Dunning-Kruger curve describes perceived knowledge versus actual knowledge, where initial perceived knowledge is low, then skyrockets after 6-12 months, and may decrease as actual knowledge increases.

“so the dunning-kruger curve is basically perceived knowledge versus actual knowledge and the really interesting thing is when we start in a subject since we are aware that we have no knowledge our perceived knowledge pretty much aligns with how much knowledge we have which is none but pretty quickly our perceived knowledge skyrockets it goes very very high usually after about six to 12 months of you know being involved in a particular subject and we get to this some people never get to this inflection point where it starts to come back down but eventually if you keep learning and keep learning and keep learning you realize oh wow i didn't know as much as i thought i did because i thought i knew that but then this contradicts it and so you start having this like downward turn even though you're learning more your actual knowledge is going up your perception of your knowledge starts going down”
