Yeah people in hard sciences can't really fake as a workhorse. However, I have worked at a job where almost everyone but me was an onshore offshore copy/paste StackOverflow "software engineer" and they were absolutely fakers but they truly didn't see themself as such. Their main defense was to make sure to only hire other "engineers" who were even worse than them. That type of hiring cascades to zero nicely.
For the latecomers - It was originally posted here with the title on the page, not the title in the URL: "Why Everyone Feels Like They’re Faking It".
I was also was gonna post something like "...uh, no I don't", but decided to hold off and see what others thought. Guess it was a good idea for a different reason, the title on here having changed.
