Host: Matt Abrahams
Guest: Steven Pinker, Professor of Psychology, Harvard University

Episode: 231

Overview of the Episode

This episode examines the complexity and importance of indirect communication—why we often hint or beat around the bush instead of being direct, and how these secret signals shape our relationships and social interactions. Host Matt Abrahams interviews renowned linguist and psychologist Steven Pinker about the concepts in his book, When Everyone Knows that Everyone Knows: Common Knowledge and the Mysteries of Money, Power, and Everyday Life. Together, they deeply explore the mechanisms, motivations, and advantages of indirectness in language, the role of context and culture in communication, and actionable strategies to improve our clarity and effectiveness.

Key Discussion Points & Insights

1. Why We Rarely Say Exactly What We Mean

• Indirectness as a Feature, Not a Bug
  • Pinker explains that much of communication involves hints, euphemisms, or innuendo rather than explicit statements.

    “An awful lot of the time, we don’t just blurt out what we mean in so many words, but we hint, we wink… counting on our listener to read between the lines.” – Steven Pinker (02:39)

• Common Knowledge and Its Social Function
  • The concept of ‘common knowledge’: It’s not just about both parties knowing something, but both knowing that the other knows, recursively.

    “Common knowledge is important because it's necessary for coordination… Relationships are propped up by common knowledge.” – Steven Pinker (04:14)

  • Direct statements create common knowledge, which can alter or even rupture social ties. Indirectness maintains plausible deniability and preserves relationship dynamics.

2. The Power of Context

• Context Determines Meaning
  • Abrahams highlights how phrases take on different meanings depending on situational context.

    “If you go see a doctor and the doctor says, ‘How are you doing?’, that has one meaning. But if you're in a bar and somebody says, ‘How are you doing?’, that has a very different meaning.” – Matt Abrahams (07:07)

• Navigating Social Nuance
  • Pinker discusses how children’s lack of indirectness is charming but socially costly; adults learn through feedback and social cues to master the art of ambiguity.

3. Learning Indirect Communication

• Developing Social Intelligence
  • Mastery of indirectness comes not from formal education, but through social feedback and observation.
  • Familiar phrases (e.g., “Could you pass the salt?”) become conventionalized, while novel situations require more metacognitive calibration.

4. Cultural Variations in Communication

• Indirectness Crosses Cultures, but Varies in Degree
  • Every culture uses indirectness, but the manner and level differ.

    “Japan is famously indirect and polite… conversely, there are cultures like New York or Israel, where people are famously blunt.” – Steven Pinker (11:15)

  • Misunderstandings can occur in multicultural settings due to differing indirectness norms.

5. The Necessity of Strategic Indirectness

• Indirectness as Social Glue (or Foundation)
  • While people claim to prefer blunt honesty, Pinker argues that strategic ambiguity is essential for functioning relationships.

    “We’re all kind of hypocrites about our hypocrisy… if you actually say [the truth], it kills the friendship.” – Steven Pinker (12:16)

  • Maintaining relationships often depends on participants not fully acknowledging certain truths to each other.

6. Effective Writing: Clarity, Conciseness, and Grace

• Clarity and ‘The Curse of Knowledge’
  • Writers often assume readers share their background.

    “The curse of knowledge is a psychological phenomenon… if you know something, it’s very hard to imagine what it’s like not to know it.” – Steven Pinker (13:56)

• Grace as Flow and Coherence
  • Good prose is melodious, vivid, concrete, and guides readers through logical transitions with connecting words.

7. Metaphors in Language

• The Hidden Prevalence of Metaphor
  • Everyday language is deeply metaphorical, shaping thought and interaction.

    “A relationship is a journey. War. Argument is war. Knowing is seeing… We don’t even realize we do it.” – Steven Pinker (17:23)

• Impact on Negotiation and Influence
  • Metaphors can shape approach and outcomes in negotiation and conflict.

Notable Quotes & Memorable Moments

• On Social Relationships:

  “Direct speech, blurting something out, generates common knowledge… and that’s why blurting something out that contradicts assumptions of the relationship can blow everything up and be deeply awkward.” – Steven Pinker (05:44)

• On Cultural Differences:

  “All cultures have some kind of indirectness. The level just varies, and often tourists... have to get used to it.” – Steven Pinker (11:15)

• On Radical Honesty:

  “[People say] ‘Why don’t we just cut the crap and say what we mean?’ The answer is no, it would be awful. A lot of our relationships really depend on common assumptions that are, at the end of the day, fictions.” – Steven Pinker (12:16)

• On Metaphors:

  “We know this from a brilliant work… Metaphors We Live By… There are more metaphors in language than we realize. Often we’re completely unaware of them.” – Steven Pinker (17:23)
