ELI5: why can i proof read for a long time and find no mistakes, but as soon as i give it to someone else to proof, all the mistakes are so apparent as they are proofing the document?

This seems to happen a bit with me, i may have to look over a presentation for mistakes. I will pick up the initial set of mistakes, but then everything looks perfect to me. When i go to show it to a supervisor, suddenly, all these mistakes that i hadn't seen before are now very apparent as i go through it with the supervisor.

Because you already know what you are trying to say, and instead of actually reading what is there your brain fills it in for you with what you intended to say. Pro tip: proof your own work by reading it backwards word-for-word and you'll find a ton of those mistakes also.
