The Rewrite Diagnosis

Exercise 3: The Rewrite Diagnosis

Layers Used: Layer 2 (Reasoning Receipt)

Building On Previous Chapters

Chapter 2's Error Taxonomy applied to communication. You are detecting strategic errors, not factual ones. The same diagnostic rigor from Chapter 2 applies -- but the errors are in emphasis, tone, and audience mismatch rather than logic or fact.

What You Do

You receive a poorly written business email (generated by AI to be subtly wrong in tone, emphasis, and audience awareness -- not grammar). Diagnose what is strategically wrong: What is this email optimizing for that it should not be? What will the recipient feel? What will they do (or not do) as a result? Then rewrite it.


Your Deliverable

A diagnosis document (before rewriting) containing: the strategic errors identified (not grammar -- tone, emphasis, audience mismatch, buried lead, etc.), the predicted recipient reaction, and the predicted behavioral outcome. Your rewritten email. A brief explanation of every change you made and why.

AI Check Prompt -- Copy and paste into claude.ai or chatgpt.com
I received a poorly written business email and was asked to diagnose its
strategic problems (not grammar) and rewrite it. Please:

(1) Evaluate my diagnosis -- did I identify the real strategic problems? Did I
miss any?
(2) Rate my rewrite: is it genuinely better strategically, or did I just
improve the surface while missing the core issue?
(3) Compare the likely recipient reaction to the original email vs. my
rewrite -- would my version actually produce a different behavioral outcome?
(4) What is the single most important improvement in my rewrite, and what is
the one thing I still got wrong?
(5) Rewrite the email yourself. I will compare your version with mine to learn
what I missed.

Original email: [paste].
My diagnosis: [paste].
My rewrite: [paste].

Finally, complete the Thinking Score Card for this exercise:
Independent Thinking (1-10), Critical Evaluation (1-10),
Reasoning Depth (1-10), Originality (1-10), Self-Awareness (1-10).
For each score, give a one-sentence justification.

What This Teaches You

You learn to diagnose communication failures at the strategic level -- not "is this well-written?" but "will this achieve its purpose?" This is the skill that separates someone who writes from someone who communicates.
