Addendum is a publication for thoughtful disagreement. We examine business writing, challenge weak assumptions, surface missing context and extend arguments that deserve a second look.

How Addendum works
Every piece should make the reader better informed than the original article alone. Disagreement is useful only when it introduces evidence, context, reasoning or a more complete frame.
Explain what the original article actually argues before criticizing it.
Focus on a claim, assumption, omission, framing choice or limitation that can be examined clearly.
An Addendum should extend understanding, not simply score points against another writer.
Why “Addendum”?
We are interested in arguments that are almost right, incomplete in revealing ways, persuasive for the wrong reasons, or simply missing a perspective worth preserving.
