This looks like nonsense, especially the hilarious costs&#x2F;benefits calculated to the nearest dollar.<p>And yes, of course toxic management is more likely to be a problem, even though it remains curiously unstudied by the HBS.<p>Even so, I think the takeaway - don&#x27;t hire self-aggrandising control freaks, no matter how talented they seem to be - is probably sound at every level.<p>Except possibly the CEO. (Was Steve Jobs toxic? Bill Gates? Haven&#x27;t most toxic CEOs been disastrous for their companies?)
