Divide and Conquer

One-liner: Deliberately sowing rivalry or distrust between colleagues so they never compare notes, unite, or notice the same pattern is happening to more than one of them.

Also known as / related terms: Divide and rule, playing favorites, inner-circle politics, pitting people against each other, tertius gaudens.

What it is

Keep people rivalrous and they never compare notes.

Divide and rule (divide et impera) is a long-documented power strategy: create or exploit divisions between people who might otherwise unite against a common source of the problem, so no coalition can form. The sociologist Georg Simmel gave this its formal grounding in his 1908 treatise on the triad, later translated as The Sociology of Georg Simmel: any three-party structure creates the possibility of a “tertius gaudens”, literally “the third who benefits”, a position from which one party profits precisely because the other two are divided rather than aligned. Simmel further distinguished a broker who merely benefits from an existing division (tertius gaudens) from one who actively manufactures and sustains it (divide et impera), the more deliberate, higher-effort version of the same structural advantage. In organizations, this shows up as a boss or colleague who deliberately creates rivalry, unequal treatment, or an “inner circle,” so subordinates compete with each other instead of comparing experiences. Workplace bullying researcher Dorothy Suskind, Ph.D., writing in Psychology Today, describes how bullies create an inner circle of compliant colleagues who will not threaten their reign, while purposefully excluding talented and curious employees who could question them, a mechanism she frames as calculated exclusion rather than accident. The Workplace Bullying Institute’s survey data on bully tactics found that 55 percent of targets reported the bully had encouraged people to turn against the person being tormented, making active recruitment of coworkers against a target a measured, common tactic rather than an edge case.

What it looks like (workplace)

Before: Two peers who used to share drafts and compare notes freely, ordinary collegial trust.

The incident: Each one is privately told, separately, that the other criticized their work to the manager. Neither version is checked against the other.

The month after: The two peers now compete for the same scraps of approval instead of collaborating, and neither ever learns that the exact same thing was done to both of them.

How it actually unfolds

The roles here are an operator, a rotating cast of favorites, and a set of peers kept too divided to compare notes.

1. Map. The operator learns who trusts whom, and where a coalition could plausibly form if left alone.
2. Create asymmetry. Private, flattering, and incompatible versions of events go to different people, see Triangulation for the delivery mechanism. One person gets elevated into a favorite, see The Golden Child, sometimes rotated deliberately so no one’s position ever feels secure, an application of Intermittent Reinforcement to the favor itself.
3. Seed distrust. Each party hears a version of what the other supposedly said, often through a willing carrier who amplifies it further, see Flying Monkeys.
4. Reward rivalry. Overlapping assignments go to whoever “gets there first,” and peers who used to collaborate start guarding information from each other instead; see Knowledge Hiding / Information Hoarding for this as an induced, not innate, symptom.
5. Harvest. Complaints stay individual and easy to dismiss one at a time, and the operator remains the only person in the system with the full, undivided picture.

Why they do it

If colleagues compare notes, they may realize the same treatment is happening to more than one of them, which is the first step toward a shared, credible complaint. Keeping people rivalrous, or simply too busy competing with each other, prevents that comparison from happening. Simmel’s structural point is the deeper reason it works so reliably: a triad, unlike a pair, always contains the possibility of a tertius gaudens position, and divide and conquer is simply the deliberate, sustained occupation of that position rather than an accidental drift into it.

How to protect yourself

Comparing notes is the thing the tactic prevents. So compare notes.

• Talk to coworkers directly about your actual experiences rather than relying on what you’ve been told secondhand about them.
• Notice when you’re being told a private, flattering version of events that doesn’t match what a peer is being told.
• Resist competing for scraps of favor that come at a colleague’s expense. That competition is the mechanism, not a side effect.
• If you suspect a pattern, ask one trusted colleague a specific, neutral question (“How did that meeting go for you?”) rather than a leading one.

Label note: Divide and rule is a long-established term in political and organizational-power literature, with real formal grounding in Georg Simmel’s sociology of the triad, applied here to a specific workplace mechanism documented separately in workplace bullying research. It is distinct from Coalition-Building/Mobbing (a group organized against one target) and Triangulation (routing communication through a third party): divide and conquer is specifically about preventing multiple people from comparing notes and recognizing a shared pattern.
