Treat charisma as a dynamic balance between warmth and competence rather than a fixed personality trait. Warmth answers whether people can trust you; competence answers whether they can rely on you. Too much warmth without competence can make you likable but underestimated, while competence without warmth can make you impressive but intimidating or suspicious. Begin by diagnosing the imbalance in the current interaction, then deliberately add cues from the missing side. Advanced communicators use the two dimensions like a thermostat: they raise warmth during rapport-heavy encounters and increase competence when authority, precision, or execution matters. The goal is not maximum intensity on either dimension, but enough of both to make your message believable and digestible.
Origin
Vanessa Van Edwards developed this science-based model while cataloging behavioral cues for her book Cues. Extracted from Habits & Hustle.
Core principles
- 01People judge both trustworthiness and capability.
- 02Warmth makes competence easier to accept.
- 03Excess warmth invites underestimation.
- 04Excess competence can create suspicion or intimidation.
- 05Charismatic communicators adjust their cue balance deliberately.
How to run it
- 1
Diagnose the context
Decide whether the interaction primarily requires trust, authority, or an even blend of both. Notice whether your habitual style already overweights one dimension.
Pro tip Use the questions “Can they trust me?” and “Can they rely on me?” as a rapid diagnostic.
Watch out Do not assume that being highly capable automatically makes your ideas persuasive.
- 2
Add warmth cues
Show friendliness, openness, positive emotion, or collaboration when people may find you cold or intimidating.
Pro tip Use genuine smiles, acknowledgment, inviting language, or visible listening.
Watch out Warmth without boundaries or competence can encourage dismissal and overcommitment.
- 3
Add competence cues
Demonstrate clarity, preparation, decisiveness, evidence, or execution when people like you but do not take you seriously.
Pro tip Use specific numbers, direct language, structured gestures, and clear next steps.
Watch out Doubling down on competence when people already feel intimidated can worsen the imbalance.

Read the response and recalibrate
Watch whether people become more open, more respectful, or more engaged. Turn the warmth or competence dial again as the interaction develops.
Pro tip Treat different settings as requiring different thermostat settings.
Watch out Do not copy another person’s charisma recipe so closely that your behavior becomes inauthentic.
In the wild
A technical lead notices that colleagues respect her expertise but resist her proposals. She opens by acknowledging their concerns and framing the proposal as a collaborative solution, then presents the evidence, implementation plan, and measurable outcome.
→ The same competent idea becomes easier for colleagues to trust and support.
Common mistakes
Maximizing only one trait
Extreme warmth or competence creates a predictable blind spot instead of complete charisma.
Treating charisma as fixed
The model works as an adjustable contextual skill, not a permanent personality label.
Is it for you?
Best for
People who need to build trust and credibility across changing social or professional situations.
Not ideal for
Interactions where deliberate impression management would be deceptive or manipulative.
From the transcript
“the only two words that make up 82% of our judgments are warmth, friendliness, like ability, openness, and competence, capable, powerful, efficient.”
“very highly charismatic people use their warmth and competence like a thermostat or like a dial.”
“competence without warmth leaves us feeling suspicious.”
