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
- Identify the Thought
Acknowledge the harsh internal thought (e.g., "Lenny botched that interview").
- Filter for Intent
Check if your goal is to help or to blame.
- Translate to Inquiry
Convert the judgment into a curious question ("I wonder if you felt you missed an opportunity in that interview?").
- 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?"
