What Is Communication?

Communication is the process of exchanging information, ideas, thoughts, feelings, and messages between individuals or groups through verbal, nonverbal, and written means.

Why It Matters

The Truth About Communication

Myth: Some people are "natural communicators"
Reality: Communication is a learnable skill developed through practice

Myth: What you say is what matters most
Reality: How you say it (and what you don't say) often matters more

Myth: Being articulate means being smart
Reality: Clear, simple communication requires more intelligence than complex language

Myth: Extroverts are better communicators
Reality: Introverts often excel through better listening and preparation

The Communication Model

Basic Model

Sender → Encoding → Message → Channel → Decoding → Receiver

Components Explained

Where Communication Fails

Most communication problems occur at these points:

1. Encoding - Sender uses unclear language or wrong words
2. Channel - Wrong medium chosen (email vs. face-to-face)
3. Noise - Physical distractions, emotional states, biases
4. Decoding - Receiver misinterprets based on their context
5. Feedback - No confirmation that message was understood

Core Principles

1. Clarity Is King

Principle: Simple, clear messages beat complex, clever ones every time.

Application:

• Use simple words (95% of communication should use common vocabulary)
• One main idea per message
• Concrete examples over abstract concepts
• Define jargon or avoid it entirely

Example:

• ❌ "We need to synergize our core competencies"
• ✅ "Let's combine our strengths to solve this problem"

2. Audience First

Principle: Always consider what your audience needs, not just what you want to say.

Questions to ask:

• What do they already know?
• What do they care about?
• What action do I want them to take?
• What objections might they have?
• How are they feeling right now?

3. Context Matters

Principle: The same words mean different things in different contexts.

4. Intent ≠ Impact

Principle: What you mean to communicate and what is actually received are often different.

Example:

• Your intent: "I want to be helpful"
• Your words: "Have you tried just working harder?"
• Their interpretation: "You think I'm lazy"

Solution: Ask for feedback to ensure your impact matches your intent.

5. Listening > Speaking

Principle: Communication is more about understanding than being understood.

Statistics:

• We speak at 125-150 words per minute
• We can listen at 400-500 words per minute
• We typically retain only 25-50% of what we hear
• We spend 45% of communication time listening (but do it poorly)

6. Nonverbal Dominates

Principle: What you don't say often speaks louder than what you do say.

The 7-38-55 Rule (Mehrabian):

• 7% - Verbal (actual words)
• 38% - Vocal (tone, pitch, pace)
• 55% - Visual (body language, facial expressions)

Note: this applies only to messages about feelings and attitudes in Mehrabian's narrow experiments, and is widely misapplied as if it described all communication. For factual content, words carry most of the load.

7. Feedback Is Essential

Principle: Without feedback, you're guessing whether communication worked.

Seek feedback through:

• Asking questions ("Does that make sense?")
• Observing reactions (facial expressions, body language)
• Requesting confirmation ("Can you summarize what we agreed?")
• Creating safety for honest responses

The Psychology of Communication

Cognitive Biases Affecting Communication

Emotional Intelligence in Communication

Four key abilities:

1. Self-awareness - Understanding your emotional state
2. Self-management - Controlling your reactions
3. Social awareness - Reading others' emotions
4. Relationship management - Responding appropriately

Trust and Credibility

Communication effectiveness depends heavily on trust:

Building trust through communication:

• Consistency (words match actions)
• Authenticity (genuine, not performing)
• Competence (knowing what you're talking about)
• Care (showing you have their interests in mind)
• Vulnerability (admitting mistakes, uncertainty)

Setting Your Foundation

Self-Assessment

Before improving, understand your current state:

Strengths:

• When do people seem to understand you easily?
• What communication contexts feel natural?
• What feedback have you received about your communication?

Weaknesses:

• When do misunderstandings happen most?
• What situations make you nervous?
• What do people say you could improve?

Your Communication Goals

Set specific, measurable goals:

Poor goal: "Be a better communicator"
Good goal: "Reduce filler words to fewer than 5 per minute in presentations"

Poor goal: "Stop being nervous"
Good goal: "Give one presentation per month to build confidence"

Creating Your Practice Environment

Daily opportunities:

• Every conversation is practice
• Video/voice recordings for self-review
• Journaling about what worked/didn't

Weekly opportunities:

• Team meetings (practice clarity)
• One-on-ones (practice listening)
• Presentations (practice structure)

Monthly opportunities:

• Formal presentations
• Difficult conversations
• Leading meetings

Exercises

Exercise 1: Message Analysis

Take a recent communication that went poorly:

1. Identify which part of the communication model failed
2. List 3 barriers that were present
3. Rewrite the message using the core principles
4. Identify how you'd confirm understanding next time

Exercise 2: Self-Recording

1. Record yourself explaining a concept (2-3 minutes)
2. Watch/listen without judgment, taking notes
3. Identify:
   • Clarity issues (jargon, complexity)
   • Filler words ("um," "uh," "like")
   • Pace (too fast/slow?)
   • Energy level
4. Practice again, addressing one issue

Exercise 3: Listening Baseline

In your next three conversations:

1. Set a timer for the conversation
2. Estimate percentage you spoke vs. listened
3. Count how many times you interrupted
4. Rate how much you actually retained (test yourself)

Goal: Awareness of current habits before changing them

Exercise 4: Barrier Identification

For one day, track every communication issue:

1. What was the message?
2. What went wrong?
3. Which barrier(s) caused it?
4. How could it have been prevented?

Key Takeaways

1. Communication is a system - Multiple components must work together
2. Barriers are everywhere - Identify and address them proactively
3. Intent ≠ Impact - Always verify understanding
4. It's learnable - Anyone can become an excellent communicator through practice
5. Start with awareness - You can't improve what you don't measure
6. Listening matters most - Focus on understanding, not just being understood
7. Context shapes meaning - Same words mean different things in different situations
