If the author even knows a six from a ten. I'm continually surprised how often bosses fall for con-artist employees. I don't mean ones that are just clicking along and doing the minimum; I mean employees that are actively destroying your business. The salesman that games the incentive system or overpromises to make sales. The developer that "makes it work", but writes code so labrythine and undocumented as to make it impossible for any other developer to succeed. Or the middle manager that will sabotage other projects inside the company in order to look good in comparison. The easy question to answer is "should you hire good employees?". The hard question to answer is "how do you determine good vs bad?" Maybe those sixes aren't trying because they're worried that any exceptional performance will be seen as a threat to a paranoid senior staff member. For every one true 10/10 employee there are five con-artists. I'd argue the con-artists are a bigger threat than someone who's just there to punch a clock.
