Podcast: How to Be a Better Human
Host: Chris Duffy (TED)
Guest: Charles Duhigg, author of Super Communicators
Date: September 15, 2025

Overview

This episode explores the art and science of communication with Pulitzer Prize-winning journalist Charles Duhigg, focusing on practical skills and mindsets that turn everyday chats into genuine connections. Drawing from neuroscience, real-life anecdotes, and research, Duhigg and Duffy discuss what makes someone a “super communicator,” the power of vulnerability, how communication shapes trust, and actionable techniques anyone can use to improve their conversations—whether at work, at home, or anywhere else.

Key Discussion Points & Insights

1. Defining “Super Communicators”

• Super Communicators: The people you immediately want to talk to when you’ve had a rough day. They are not born special—these are learned skills anyone can adopt.
• Main skills: Knowing how to ask meaningful questions, signaling genuine listening, demonstrating empathy, and choosing when to solve and when to simply support ([01:15] Charles Duhigg).

2. Communication Is More than Information Exchange

• Connection over facts: Communication is less about the words and more about building a sense of connection and trust.
  • “The goal of communication is not just to exchange information. The goal is to feel connected to each other.” ([05:15] Charles Duhigg).
• Evolutionary basis: Human success as a species stems from our “superpower” of communication, which fosters trust and cooperation.

3. The Messy Reality of Great Conversations

• Messy ≠ Bad: The best conversations are often nonlinear, filled with interruptions, tangents, and vulnerability ([06:12] Charles Duhigg).
• Vulnerability defined: Not just about sharing secrets or crying, but offering information others could judge, which creates a neurological openness to connection.

4. Neurological Synchronization (Neural Entrainment)

• Physical synchronization: As people connect, their breathing, heart rates, and even pupil dilation can sync—even via virtual conversation ([08:24] Charles Duhigg).
• Brain activity: “If we could see inside our brains…my neural activity and your neural activity are beginning to look more and more similar.” ([08:24] Charles Duhigg).
• Why it matters: This mirroring releases dopamine, creating pleasure and reinforcing connection.

5. The Illusion of Communication

• Awareness gap: Many poor communicators think they're great—highlighted by the George Bernard Shaw quote:
  “The single biggest problem with communication is the illusion that it has taken place.” ([10:01] Chris Duffy)
• Humor as a connector: Laughter signals a desire to connect and is an invitation to reciprocity, not just a joke ([10:20] Charles Duhigg).

6. Three Types of Conversations (and the “Matching Principle”)

• Practical: Focused on plans and fixing problems.
• Emotional: Sharing and validating feelings, not solving them.
• Social/Identity: How we relate to each other and to society.
• The Matching Principle: Successful communication happens when both parties are having the same type of conversation at the same moment ([11:29] Charles Duhigg).

Memorable Example:

• “If I go to the hardware store…trying to have a practical conversation…and they go, ‘that sounds so hard. I hear you and you are seen,’ I’d be like, what is happening?” ([13:01] Chris Duffy)

7. Communication Is a Learned Skill

• No one is born a “super communicator”—paying attention and practicing specific techniques is what builds skill ([13:52] Charles Duhigg).

Actionable Skills and Mindsets

1. Ask Deep, Invitational Questions

• Super Communicators ask more (especially deep) questions.
• Deep Questions: Probe values, beliefs, or experiences. They need not be intimidating.
  • E.g., Instead of “What hospital do you work at?”—ask, “What made you decide to go to medical school?” ([18:37] Charles Duhigg).
  • Invitational, not mandatory: It’s about inviting stories, not prying.
• Follow-Up: It’s natural and powerful to answer your own deep question for reciprocal openness ([21:09] Charles Duhigg).

2. Prove You’re Listening

• Follow-up questions: Show investment in the conversation.

• Nonverbal cues: Eye contact, leaning in, echoing emotions (laughter, affirmations) ([21:09] Charles Duhigg).

• Looping for Understanding:

  1. Ask a (deep) question
  2. Paraphrase what you heard
  3. Ask if you got it right
  • This boosts the other person’s willingness to listen to you by 10–80% ([23:52] Charles Duhigg).

  “The goal of a conversation is not for me to convince you that you’re wrong and I’m right…The goal is to understand each other.” ([24:42] Charles Duhigg)

3. Recognize Socialization Patterns

• Gender and communication: Not biological, but habituated. Men and women are socialized differently but can learn all modes.
  • Men often default to “practical” talk even about emotional issues; learning to match emotional mindsets is key ([28:43] Charles Duhigg).

4. Matching the Conversation Type and Mindset

• Practical conversation: “What are we trying to do?”
• Emotional conversation: “How do we feel about this?”
• Social conversation: “Who are we?” ([32:05] Charles Duhigg)

5. Adapting to Different Communication Mediums

• Medium matters: Communication over email, phone, or in person each has unspoken “rules.” Overemphasize politeness and avoid sarcasm in digital forms ([36:39] Charles Duhigg).

6. “High Centrality Participants” and Group Influence

• Certain people, super communicators, can synchronize groups—often without pushing their own ideas but by echoing and amplifying others’ contributions ([38:42] Charles Duhigg).

Memorable Quotes & Moments

• “Communication is Homo sapiens’ superpower.” – Charles Duhigg ([05:15])
• “Vulnerability…is a neural cascade that happens in our brain when I tell you something you could judge.” – Charles Duhigg ([06:12])
• “If you ask super communicators…if they’ve always been good at communication, they almost inevitably say no.” – Charles Duhigg ([13:52])
• “Try and ask a deep question that you normally wouldn't ask…What you'll find is…the other person…is going to love being asked that question.” – Charles Duhigg ([40:50])
• “We can live peacefully side by side [even if we disagree] if we feel like the other person understands us and we understand them.” – Charles Duhigg ([24:42])

Practical Takeaways

• Challenge for listeners: Ask one deep, invitational question today or tomorrow—notice the difference it makes in the connection.
• Build habits: Practice these small skills—deep questions, active listening, and matching conversation types—to make them automatic over time.
• Reciprocity wins: Demonstrating understanding encourages others to do the same; real communication is a two-way, messy, and rewarding process.

Final Thought

Duhigg’s research and insights make the case that anyone can become a “super communicator” by developing simple—yet powerful—habits of curiosity, empathy, and active listening. Even imperfect, messy conversations are valuable when approached with the right mindset.
