Well, you're wrong! In my experience you run as fast as you can to get away from the person who claims to know it all, that's the person who is going to get you killed! Operating inside the "I know everything about everything' bubble is the equal to the old 'here, hold my beer and watch this' How many folks have been killed by a FKIA?
A good Inspector will look at the presented item, check documentation and drawings, utilize the OHM,IPL, or SRM to ascertain things are done correctly then either accept or reject the item, if the item is rejected he/she will then document the discrepancies and submit that information to Engineering to make a final 'yea' or 'nay'.
Would you fly with someone in a complex aircraft who had the check list and emergency procedures committed to memory? (I've worked with and for people I wouldn't trust to steer a tricycle without an accident) want to see how good your memory is? try to remember the steps required in doing CPR off the top of your knob, perhaps seeking wise council when I'm not sure or have doubts is part of what's kept me out of a very small room for periods of 10 years with someone named 'Bubba" who figures you are worth two packs of Marlboros.
Like my signature line states, and I don't see any burning sandwiches-
Mom raised ugly kids, not stupid ones!
