In my personal experience, the majority of people do not think like this. When I was going through grade school, my parents/teachers/etc. often did use words like "awe-inspiring achievements", even for fairly mundane things like getting perfect scores on standardized tests. I got into Amherst through a process very much like the article describes (I had terrible grades but had worked at an all-teenage dot-com startup and aced my standardized tests). In the "brag session" where the director of admissions lists all the awe-inspiring resumes of the incoming freshman class, she said "And one of the students passed 8 AP tests without taking a single AP class", and a murmur of appreciation passed along the crowd. Really, it's not that hard, you read a book and then you pay $75 for a test - but most of them don't know that.
I think it's great that there's more understanding going around of what achievement actually stems from. But that understanding certainly isn't universal, and in the meantime, you can hack people's perceptions of you by playing to the blind spots in their own knowledge. "Everything is impossible until I know how to do it, and then it's trivial."
Passing AP tests is impressive? Whoa.
Explaining the "amazing" reason that everyone picks his choice seems much less impressive at that point, particularly as it mostly seems like an ad for a book.
Does anyone actually talk like this (from the comments):
It’s interesting that you mention science fairs. I actually have a chapter in my new book where I take the awe-inspiring resumes of two Intel winners, then break down, step by step, the reality of their achievement
