Communication styles

Ask what your communication style is and you get one of two quartets. The assertiveness tradition sorts people into passive, aggressive, passive-aggressive and assertive. The social styles tradition sorts them into analytical, driver, amiable and expressive. Both are useful. Neither is a fact about you the way your height is.

Why the simple definition misleads

Style sounds like a property, something you carry from room to room. Watch anyone for a week and that falls apart. The same manager is direct with her team, hedging with her director, and silent in a meeting where the CFO is unhappy. Nothing about her personality changed between nine and eleven. The stakes changed, and so did the status gap.

So the honest definition carries a condition: your style is the habit you fall back on when saying the true thing costs you something. Questionnaires filled in on a calm Tuesday describe someone you only partly are. The version worth knowing shows up in the fifteen minutes when the project is late and somebody has to say so.

Passive-aggressive is rarely a personality flaw. It is usually what assertiveness turns into once people learn that objecting openly gets punished.

It also gets confused with three neighbours. It is not tone, which changes sentence by sentence. It is not channel preference, the habit of choosing email over a call. And it is not personality type, though an entire assessment industry depends on people treating those two as interchangeable.

The four communication styles

This is the set most people mean, and it comes out of assertiveness training, popularised by Robert Alberti and Michael Emmons. The four are best understood by what each one protects.

Only one of the four is uncomfortable now and cheap later. The other three are the reverse.

What it looks like in practice

A team lead knows a launch date is unrealistic. Four versions of the next hour. The passive one says the date is tight but the team will do their best, then absorbs it over the weekend. The aggressive one says the date is ridiculous and whoever agreed it wasn't listening, which is true and buys nothing. The passive-aggressive one nods, then tells three colleagues it will obviously slip. The assertive one says: two features cut and we hit that date, or full scope three weeks later, and I need a decision by Thursday.

The last version is not braver. It is more specific. Assertiveness in practice is nearly always concreteness: a stated position, the reasoning, and a real ask.

Communication style vs personality type

Instruments cluster around this: MBTI, built by Katharine Briggs and Isabel Briggs Myers on Jung's typology, and the DISC family, whose dimensions trace to William Moulton Marston's 1928 writing though the assessments came from others decades later. They give teams a shared language, which has real value. They are much weaker as predictions, and MBTI is widely criticised for people re-testing into a different type. Use them to start conversations, not to allocate work.

The other four: social styles

David Merrill and Roger Reid mapped style on two axes: how much someone pushes, and how much emotion they show. That yields analytical (wants the data first), driver (wants the decision first), amiable (wants the people handled first) and expressive (wants the vision first). The use of this is not labelling colleagues. It is noticing that a driver reads your careful three-paragraph preamble as evasion, while an analytical reads your headline with no working as arrogance. Same message, two failures, both fixed by moving one paragraph.

How to widen your range

• Name your default under pressure, not in general. Think of the last time you disagreed with someone senior. What did you actually do? That is your style. The rest is self-image.
• Keep one assertive structure and overuse it. Position, reason, ask: "I'd push the date. The integration isn't tested. Can we decide by Thursday?" Boring, repeatable, and it works in a second language.
• Soften the delivery, never the message. Warmth is free. Hedging until the point disappears is the passive move in good manners.
• Ask before you push. One genuine question about the other person's reasoning changes what you have to argue against. This is where active listening does the work.
• Describe behaviour and impact, not character. "You're aggressive in reviews" starts a second fight. The SBI feedback model gives you the sentence that doesn't.
• Fix the conditions too. If nobody on your team is assertive with you, the problem is not four individual styles. Psychological safety sets the ceiling on how honest anyone can be.

Range matters more than type. A manager with one register is limited whichever register it is, and the leaders people call good communicators are usually the ones with more gears. More on that in communication skills for leaders.

Communication styles in the workplace: where they actually bite

Styles are invisible while everyone agrees. They surface, and start costing money, at four specific moments: escalation (the passive engineer who flags the risk once, quietly, and is later blamed for not pushing); handover (the driver who compresses a week of context into four bullet points and calls it efficient); review (the aggressive senior whose feedback is accurate and whose team has stopped showing early drafts); and cross-team requests (the passive-aggressive “sure, if that's the priority” that means no). If you want to audit a team's styles, read its escalations and handovers from the last quarter — the patterns are all there in writing.

Training range into a team follows the same rule as every behavioural skill: it moves in practice, not in description. Structured communication activities that force the failure — one-way briefs, incomplete information, a listener who may only ask questions — make each style's cost visible in the room within minutes, and the debrief attaches the vocabulary to something that just happened rather than to a slide.

How to tell what your style really is

Be sceptical of the obvious method. Self-report questionnaires measure your self-image on a quiet afternoon, and no instrument maps a person to a style the way a tape measures height. Better evidence exists, and it is less comfortable.

1. Ask three people who have disagreed with you. Not "how do I communicate", but "what happens when someone tells me I'm wrong?" The pause before they answer is the data.
2. Check whether bad news reaches you early. Teams withhold problems from aggressive managers and over-explain them to passive ones. Timing is a cleaner signal than any survey.
3. Watch yourself with a clock running. Style under real pressure is the only version that predicts anything, which is why experiential learning exposes it faster than a workshop does. Give a group a decision they disagree about and a deadline, and every default in the room is visible inside ten minutes. The Weekly Challenge runs on that principle.

Myths and common mistakes

• "93% of communication is nonverbal." A misreading of Albert Mehrabian's work, which examined how people judge feelings when words and tone contradict each other. He said himself it should not be generalised. The number gets quoted anyway.
• "Assertive means blunt." Blunt is half of assertive: your position without the invitation to disagree. That half on its own is the aggressive style with better PR.
• "Match the other person's style." Adapt pace, format and detail, yes. Matching aggression escalates it, and matching avoidance means nothing gets decided.
• "It's a style clash." Sometimes. More often two people disagree about something real, and blaming the wiring is the comfortable way out. Try conflict resolution first.
• "Now I know my type, I'm done." Knowing your default changes nothing by itself. Range comes from using an unfamiliar register in a real conversation, badly, several times.

The through-line: a communication style is a habit, not an identity. The one worth building puts the real message on the table and still leaves the other person somewhere to stand.
