The correspondence of Chomsky's Manufacturing Consent and the practice of "culture-fit" in Hiring Practices should be a note of caution to growing companies.
Over constraining your hiring, ( i.e. the aspect of "culture-fit" that is antonymical to diversity ) can lead an organisation to blindness to the true state of things ( i.e. not having diverse perspectives on customers due to a lack of diversity in employee backgrounds ).
This is why diversity is not just about fairness but also highly pragmatic.
Diversity makes for wiser corporations which makes them anti-fragile and gives them new edges in competition.
It is also why the subtle method of subverting democracy outlined in Chomsky's Manufacturing Consent as a practice to create an organisation ( or newspaper ) that outputs a world view concurrent with ones own makes for fragile democracies and administrations.
That it can happen "unconsciously" because it is easier to recognise competence in those who are like you means organisations and democracies must be vigilant against entrenched political and journalistic class evolving.
In short: critics are better friends than an echo chamber.
Or contemporaneously: firing scientists does make climate change less true.
