The 'Left-Hand Column' Detox
"Say the thing you think you cannot say... detoxify the left-hand column." — Claire Hughes Johnson
What It Is
A technique adapted from Fred Kofman to translate harsh internal thoughts (the left-hand column) into constructive, external dialogue (the right-hand column).
When To Use
- Sensing tension in a meeting
- Noticing a "pink elephant" in the room
- Spotting a recurring performance issue
- When feedback feels "too harsh" or "unsayable"
The Two Columns
┌─────────────────┬─────────────────────────┐
│ LEFT COLUMN │ RIGHT COLUMN │
│ (Internal) │ (External) │
├─────────────────┼─────────────────────────┤
│ "Lenny botched │ "I wonder if you felt │
│ that interview"│ you missed an │
│ │ opportunity in that │
│ │ interview?" │
├─────────────────┼─────────────────────────┤
│ "These teams │ "I feel like there's │
│ are fighting │ something we're not │
│ over turf" │ talking about... do │
│ │ these teams own the │
│ │ same project?" │
└─────────────────┴─────────────────────────┘
Core Principles
1. Identify the Thought
Acknowledge the harsh internal thought (e.g., "Lenny botched that interview").
2. Filter for Intent
Check if your goal is to help or to blame.
3. Translate to Inquiry
Convert the judgment into a curious question ("I wonder if you felt you missed an opportunity in that interview?").
4. Say the "Unsayable"
Speak the filtered observation directly to clear the air and build trust.
How To Apply
STEP 1: Notice Your Reaction
└── Feel frustration, judgment, or tension
└── Catch the internal thought
STEP 2: Write It Down (If Possible)
└── Left column: Raw thought
└── Right column: Constructive version
STEP 3: Check Intent
└── Am I trying to help or punish?
└── What outcome do I actually want?
STEP 4: Translate to Curiosity
└── Use "I wonder..." or "I'm curious..."
└── Frame as observation, not accusation
STEP 5: Speak It
└── "I want to share an observation..."
└── "Can we discuss something that might be uncomfortable?"
Common Mistakes
❌ Over-filtering so much that the feedback becomes vague
❌ Blurting out the raw "left-hand" thought without detoxifying
❌ Using it as manipulation instead of genuine curiosity
Real-World Example
Claire calling out a conflict between two teams in a meeting by asking, "I feel like there is something we are not talking about... do these two teams own the same project?"
