Choosing the right communication channel for tough workplace conversations

Executive overview

Authenticity at work is more complex than "always be yourself." What feels authentic to you may land as inauthentic to the other person — and the wrong communication channel can expose emotions you didn't intend to reveal.

The key insight is that richer isn't always better. Audio-only (phone or camera-off video) is often the optimal channel when you need to manage your own emotions while still signalling effort and care.

The goal isn't to be authentic — it's to communicate in a way that serves both you and the other person.

The virtual communication paradox

• Richer modes (video, in person) seem more authentic but expose unintended nonverbal signals.
• Leaner modes (email, text) feel safer but read as low-effort and uncaring.
• Emotional leakage — unintended facial expressions or body language — is the core risk in video and in-person interactions.
• Surface acting (performing an emotion you don't feel) is normal and often beneficial; the problem is when it leaks through.
• A CEO's Zoom layoff announcement went viral because video made it easy to stay self-focused rather than audience-focused.

The three-channel framework

Research across negotiators, managers, and teachers identified three patterns:

• Truly authentic emotion: use the richest channel available — video or in person.
• Surface acting (faking it for the other person's benefit): avoid video; avoid email. Use audio-only.
• Text-only is best for: early-stage brainstorming, where self-focus and avoiding anchoring to others' ideas is an advantage.

Audio-only (phone or camera-off meeting) hits the sweet spot when surface acting is needed: it signals effort over email, but eliminates facial and body-language leakage.

When to go lower-fidelity

• Synchronous in-person brainstorming is suboptimal: only one person speaks at a time, ideas anchor to what others said, and social pressure suppresses divergent thinking.
• Asynchronous, text-based idea generation produces more and better ideas; group discussion works better for evaluating and deciding.
• No single channel is universally best — the right choice depends on the goal of that specific interaction.

Making implicit context explicit

• Recipients can't hear the emotion you heard when writing a message; they read through their own assumptions.
• A three-word reply to a twenty-page report signals dismissal, even if you were just in a hurry.
• State the context: "Got it — I'll read this properly tonight and reply in detail."
• When you use an unexpected channel, explain why; it prevents the other person from filling in a negative reason.
• People make attributions when information is ambiguous; remove the ambiguity.

Calibrating authenticity vs. surface acting

• Always-on authenticity causes harm: a manager in a great mood should not open a firing conversation by announcing how happy they are.
• Weigh two factors: cost to yourself (surface acting is exhausting) vs. benefit to the other person.
• In high-stakes interactions, the cost of unchecked authenticity — extra work, damaged relationships — usually outweighs the energy cost of managing your expression.
• The balance shifts depending on the stakes and the relationship.

The pratfall effect and strategic imperfection

• People rated as highly competent but flawless are seen as less likeable and less relatable.
• In a classic study, a contestant who aced every question and spilled coffee on themselves was rated equally competent but far more likeable than one who aced every question cleanly.
• Mistakes outside your core competence (clumsy, human moments) increase warmth without reducing perceived ability.
• Leaders who project perfection make it harder for their teams to admit errors or connect with them.
• Share small, genuine non-work slip-ups (grabbing the wrong lunchbox, a clumsy weekend moment) — not fabricated ones.

Asking instead of assuming

• Almost no one asks their counterpart which communication channel they prefer before scheduling a meeting.
• Preferences vary widely: people with hearing difficulties may prefer video for lip-reading; some neurodivergent people prefer cameras off for lower stimulation; parents with sick children at home may need audio-only.
• Asking "how do you want to do this?" increases inclusion and makes people more willing to engage in future interactions.
• Channel preference is a simple question with a high return on relationship quality.
