Why words matter: leveraging language to achieve communication goals
Matt Abrahams opens the episode by framing language as a powerful tool for reaching communication goals. He introduces guest Jonah Berger and sets the focus on wording, influence, and Berger’s new book on language.
- •Language can be leveraged to achieve specific communication outcomes
- •Matt Abrahams introduces the podcast and his role teaching Strategic Communication
- •Jonah Berger is introduced along with his background and books
- •The conversation will focus on influence, persuasion, and “magic words”
Making ideas catch on: the power of word of mouth
Jonah Berger explains that the biggest impact often comes not from what organizations say directly, but from getting other people to talk. He summarizes the research-driven approach behind studying why people share and how to craft content that spreads.
- •Word of mouth can extend reach and increase impact beyond direct messaging
- •Turning customers, listeners, and colleagues into advocates amplifies ideas
- •Berger studied why people share using large-scale data across content, brands, and purchases
- •Recurring factors can be leveraged to craft messages that spread
Social currency: designing messages people want to share
Berger highlights “social currency” as a key driver of sharing: people talk about things that make them look good. He illustrates it with a story about a hidden bar and explains why secrecy and insider knowledge motivate word of mouth.
- •People share more when it makes them look smart, cool, or in-the-know
- •A “secret” experience encourages people to tell others despite being told not to
- •First-to-know status and insider information increase sharing
- •Communicators should consider how the audience will look when they repeat the message
Setting up Magic Words: small shifts in wording, big behavioral effects
Matt pivots to Berger’s book Magic Words and quotes the idea that word choice signals power, blame, and the meaning of actions. Berger explains that people focus on what they want to say, but often overlook how specific wording changes outcomes.
- •Small language changes can meaningfully affect persuasion, attention, and connection
- •People often think about the “what” more than the “how” of communication
- •Understanding the “science of language” can increase impact across situations
- •Magic Words is organized around types of words that shape perception and behavior
The SPEACC framework: six categories of “magic words”
Berger introduces his framework for the book: SPEACC. He previews the categories and then chooses to focus on how questions work as more than information-gathering tools.
- •SPEACC stands for similarity, posing questions, emotion, agency/identity, concreteness, and confidence
- •Questions influence how others perceive us, not just what we learn
- •The episode dives into research on advice-seeking and question types
- •Frameworks can help apply language insights systematically
Asking for advice: a question that increases perceived competence
Berger describes research showing that asking for advice tends to improve how others perceive the asker. He explains this effect through egocentrism: people value their own advice and respond positively when asked for it.
- •People often avoid asking for advice due to fear of bothering others or looking weak
- •Research found advice-seekers were seen as more competent and knowledgeable
- •The effect is linked to people believing they give good advice
- •Advice questions can improve both outcomes (better input) and impressions
Follow-up questions: the simplest way to signal attention and build liking
Berger explains that follow-up questions—questions that build directly on what someone just said—shape how people feel about us. They demonstrate listening and interest, help gather richer information, and increase liking.
- •Introductory questions are polite but less impactful than follow-up questions
- •Follow-up questions demonstrate attention and genuine interest
- •They encourage the other person to share more detail
- •Using follow-ups tends to increase how much others like the question-asker
Confidence in language: certainty beats hedging (most of the time)
Matt asks about confidence, and Berger connects confidence to speaking with certainty. He describes how “hedges” (e.g., might, probably, I think) can weaken persuasion when used as unconscious verbal ticks.
- •Charismatic leaders often use language that conveys certainty
- •Hedges communicate uncertainty and can reduce persuasive impact
- •Experiments and field analyses found more hedging leads to less persuasion
- •Berger emphasizes being certain about a smaller set of things rather than broadly uncertain
A second confidence lever: turning past tense into present tense
Berger shares another language shift that signals certainty: using present tense instead of past tense. He explains that present tense sounds like a stronger assertion, which increases perceived confidence and persuasion.
- •Past tense can imply something was true only at a particular time or for one person
- •Present tense frames claims as more broadly true and enduring
- •Using present tense increases perceived certainty and persuasive impact
- •Confidence can be shaped by multiple small language choices, not just one technique
Holding attention with language: concreteness, familiarity, and emotion
Matt asks about engaging communication, and Berger distinguishes grabbing attention from sustaining it. Berger describes research on online articles showing that language style can hold attention regardless of topic, especially via concrete, familiar, and emotionally resonant wording.
- •Second-person pronouns like “you” can capture initial attention by signaling relevance
- •Holding attention depends on style as well as topic; language can compensate for less “exciting” subjects
- •Concrete and familiar language is easier to process and sustains attention
- •Emotional language plays a strong role in keeping people reading
Uncertainty-based emotion: creating a curiosity gap that keeps people reading
Berger explains that language associated with uncertainty can increase sustained attention because people stay tuned to resolve what happens next. He links this to the idea of a curiosity gap—knowing something but not everything—so audiences keep engaging.
- •Emotions differ in certainty vs uncertainty (e.g., hope and anxiety imply uncertainty)
- •Uncertainty-related language encourages continued attention to find resolution
- •People keep reading when they don’t know what will happen
- •Berger connects this dynamic to the concept of opening a curiosity gap
Motivating action through identity: from “help” to “be a helper”
Berger shares additional “subtle shifts” that change behavior, focusing on turning actions into identities. He gives examples where framing a behavior as an identity increases compliance and persistence, and where framing misconduct as an identity reduces it.
- •Switching “should” to “could” can broaden thinking and support creativity
- •Asking someone to “be a helper” can increase willingness to help compared to asking for help
- •“Be a voter” can be more motivating than “vote” by offering a desired identity
- •“Don’t be a cheater” can reduce cheating more than “don’t cheat” by attaching an undesired identity
- •Identity labels like “runner” imply stable traits more than describing an action like “runs”
Rapid-fire communication takeaways: audience, simplicity, and enabling action
In the closing questions, Berger shares his condensed communication principles. He emphasizes understanding the audience, making complex ideas simple, and helping audiences arrive at action by removing barriers rather than pushing harder.
- •Best advice slide: “Understand your audience”
- •Admired communicators make complex topics simple and accessible
- •A strong communication recipe includes audience understanding, simplicity, and driving action
- •Rather than pushing information, it can work better to identify barriers and guide audiences with the right questions
