When groups converge on agreement quickly, they stop surfacing the disconfirming information that would have improved the decision. The speed of consensus is inversely correlated with the thoroughness of the analysis behind it, meaning fast agreement is often a warning sign rather than a success.
Friction is the deliberate introduction of resistance — dissent, delay, or scrutiny — into a decision process to force assumptions into the open. Unlike interpersonal conflict, productive friction is structural and impersonal: it attacks ideas rather than people, and its purpose is to slow convergence until alternatives have been genuinely tested.
Assign specific people the formal job of arguing against the emerging decision, so that disagreement becomes a duty rather than an act of social courage. Because the dissent is role-based, it removes the personal risk that normally suppresses objections and guarantees opposing views are voiced regardless of the group's mood.
View an unusually frictionless meeting or approval process as evidence that something is being avoided rather than as evidence of alignment. The absence of pushback usually means people are withholding concerns, deferring to authority, or have not engaged deeply enough to find the flaws.
Organizations that optimize processes purely for speed and frictionlessness systematically remove the checkpoints where errors would have been caught. The cost of friction is visible and immediate while its benefits are invisible and deferred, so rational efficiency drives keep stripping out exactly the safeguards that prevent large failures.
A board approves a major initiative with full unanimity and no recorded objections, only for the venture to collapse on a risk that several members had privately doubted. The episode illustrates how unanimity can mask suppressed concern, with each member assuming their lone reservation was not worth disrupting the apparent agreement.
