THE TITANS of corporate America have had enough of their critics.

At Goldman Sachs Group, Inc., Chief Executive Officer David Solomon has who criticized his leadership and leaked to the press about problems in the bank鈥檚 consumer lending business.

At Meta Platforms, Inc., the grew jealous of how Elon Musk evaded criticism 鈥 leading to what insiders called 鈥淓lon envy.鈥 Zuckerberg is now channeling that Musk energy, less willing to take advice or listen to employee concerns over policy changes around issues such as diversity, equity, and inclusion and content moderation.

JPMorgan Chase & Co. on an internal webpage announcing the bank鈥檚 five-day-a-week return-to-office (RTO) policy after dozens balked. And CEO Jamie Dimon who asking him to reconsider , 鈥淒on鈥檛 waste time on it. I don鈥檛 care how many people sign that f**king petition.鈥 Employees who don鈥檛 like it can get a job elsewhere, he鈥檚 said.

Alphabet, Inc.鈥檚 Google made big changes to its , neutering what, for more than a decade, had been a forum for employees to express displeasure with their bosses and corporate policies.

Quashing dissent appears to be the next step in the CEO playbook for re-exerting authority after a pandemic that shifted power into the hands of workers. As CEOs return to , they have only become more emboldened 鈥 perhaps even inspired 鈥 by a White House with zero tolerance for anyone unwilling to toe the party line.

We can all understand the impulse to silence critics. They can slow decision making, create conflict and decimate morale. Admit it: We think they鈥檙e idiots and annoying troublemakers.

But there are good reasons that everyone 鈥 and especially CEOs 鈥 should not just tolerate dissenters but encourage them. That鈥檚 the argument Charlan Nemeth makes in her 2018 book In Defense of Troublemakers. The retired University of California, Berkeley psychology professor has made studying the value of dissent her life鈥檚 work, and she summed it up to me this way: 鈥淔ear consensus and welcome dissent.鈥

Consensus holds a power over us that is difficult to break. We believe so deeply that the consensus opinion must be right that found that people follow the majority as much as 70% of the time 鈥 even when that majority is wrong.

But the bigger problem is what that group-think does to our own thinking, she argues. We have a harder time seeing alternative solutions and problems that could be right in front us. We adopt the strategies and mindset of the majority and look for information that supports its position. That all leads to bad decision making.

Everything changes when we are presented with a dissenting viewpoint. It breaks the majority鈥檚 hold by broadening our thinking. We consider more information, options, and problem-solving strategies. We become more original, curious, and independent.

鈥淒issent stimulates the kind of thinking we know is related to good decision making that, frankly, you can鈥檛 teach people,鈥 Nemeth told me.

In just one of many examples in her book, Nemeth cites a study of the Supreme Court鈥檚 decisions that analyzed its written opinions for 鈥渋ntegrative complexity鈥 鈥 the ability to see and process different perspectives and ideas. The researchers found that when the Court鈥檚 majority faced a dissenting opinion, the integrative complexity of its written opinions was high. But when the Court was unanimous, its written opinions were less complex and more one-sided.

Perhaps Nemeth鈥檚 most important conclusion is that dissent has value even when it鈥檚 wrong. In the 1950s, psychologist in which participants were shown two slides side by side. One slide pictured a single line meant to act as a standard, and the other slide had three lines. The subjects had to pick the line on the second slide that was the same length as the standard. The answer was so obvious that alone they had no problem picking the correct line. But when they were told a unanimous group had picked one of the incorrect lines, 37% of agreed with the majority鈥檚 incorrect answer.

However, building upon that work found that if just one person breaks from the group and picks the other wrong line, agreement with majority鈥檚 incorrect answer dropped from 37% to 9%. 鈥淓ven if a dissenter is wrong, and even if she is not an ally, she is of major value because she breaks the majority鈥檚 power,鈥 Nemeth writes.

Dissent changes opinions, even if we don鈥檛 acknowledge or realize it. Nemeth told me people will resist publicly agreeing with dissenters, even when they鈥檝e privately been persuaded. We may have seen a flavor of that . Executives who criticized Solomon鈥檚 consumer lending expansion are gone, but the board launched a review and the bank is now exiting the consumer business.

In reality, leaders shouldn鈥檛 worry that much about quashing dissent; it鈥檚 already quashed. One study Nemeth points to found that around when they see problems because they think they鈥檒l be ignored or fear the consequences of breaking with the majority.

That鈥檚 a statistic that should frighten the CEOs more than any critic.
