“How do you know? 

I remember my days back in the corporate world (HR) that it was all but understood that roughly 25% of all employees were severely under-performing. And 10% were all but out the door and set to be fired! I also remember working with a lot of different types of people. Some were educated and smart, some were educated and, well, not so smart. Some were un-educated but smart as hell.
