The youngest director on the board has spotted a serious problem in the expansion strategy they are about to approve. The numbers don’t add up, the assumptions are optimistic, and there are warning signs in the market analysis. But when he looks around the table, he sees that the chairman is enthusiastic, the CEO has invested his political capital in the project, and the other directors are nodding. He says nothing. Six months later, the expansion fails.
Welcome to a primitive instinct that destroys board effectiveness: the tribal imperative. For hundreds of thousands of years, belonging to the group was literally a matter of life and death. Being expelled from the tribe was a death sentence. That programming did not disappear — it simply moved into the boardroom.
Loyalty over truth
The problem is subtle but lethal. It is not that directors consciously choose loyalty over truth — it is that our primitive brain doesn’t even let us see the contradiction. When the group’s leader (CEO or chairman) defends a position, questioning it feels like betrayal, not like fiduciary duty.
Solomon Asch’s research on group conformity demonstrated this: competent people denied obvious visual evidence when the group claimed the opposite. And that was with strangers in a laboratory. Imagine the effect when the group is your own board, where you have built relationships over years, where your reputation is at stake, where being seen as “not a team player” can cost you future appointments.
The inconvenient director as a tribal threat
Where personal relationships are the very fabric of the business world, this bias intensifies dramatically. The director who constantly challenges is not seen as brave — he is seen as disloyal. He is not “improving the decision” — he is “breaking the harmony.”
Family businesses add another layer of complexity: here the corporate tribe overlaps with the blood tribe. Questioning the strategy of the CEO who is the founder’s son not only risks your position on the board — it risks decades of family and social relationships. The perceived cost of dissenting becomes astronomical.
The invisible mechanisms of exclusion
The tribe has subtle ways of punishing the dissenter. They don’t formally remove him — they simply stop inviting him to the pre-meeting conversations where the real decisions are cooked up. His comments in the formal meeting are heard with courtesy but ignored in practice. His mandate is not renewed “for reasons of board renewal.” The message is clear to everyone else: loyalty is rewarded, dissent is punished. The result: boards full of competent people who have learned to read the tribal signals and adjust their behavior accordingly.
Redesigning the tribe
Effective boards recognize this instinct and intentionally redesign it. First, by redefining what “loyalty” means: it is not agreeing, it is seeking the best decision even when that requires dissent. Second, by creating explicit norms that protect and reward constructive dissent. Third, by institutionalizing mechanisms that prevent tribal punishment: anonymous board evaluations, mandatory committee rotation, executive sessions without management.
In family businesses, this requires explicitly separating the roles: “in this room we are directors, not family.” Clear protocols that depersonalize disagreement: “we are not questioning Juan the cousin — we are evaluating the proposal.”
To reflect on in your boardroom: Can your members dissent without fear of consequences? When was the last time someone changed their mind after hearing opposing arguments? Is there any director whose objections are systematically ignored? How do you define “loyalty” in practice?
If loyalty means always agreeing, you don’t have a board — you have a dysfunctional tribe.
P.S. The most valuable director is not the one who always supports the CEO — it is the one who is willing to save him from his own mistakes, even when that makes him look bad in front of the tribe.
