For years, I sent content creators pages upon pages of 'write this' briefs. The result was always the same: everything I asked for was in the text, yet the soul of the copy was suffocated by clichés I never wanted. Sitting on this side of the desk as an editor or content manager, you tend to believe the secret to flawless copy is compiling a flawless wish list. I believed it too. The briefs I handed to writers were almost as long as the copy itself. I dictated every H2 subhead, the exact keywords needed in every paragraph, and all those 'dynamic and innovative' adjectives the brand cherished.
The outcome? It didn't work. It took me a long time to understand why. Overly detailed briefs that only dictate 'what to do' turn writers into robots and drain the life right out of the text. Confined to the narrow tunnel I built, the writer merely checks off boxes rather than finding their own voice. The reason writers turn out generic work isn't a lack of direction on what to write—it's that they can't guess what not to write.
Why Telling Writers Only 'What You Want' Fails
Tell a writer 'Give us something dynamic, youthful, and professional,' and you'll likely receive a catastrophe opening with 'In today’s rapidly digitalizing world...' For years, I made this exact mistake: piling on positive directives extolling how great the brand was. Yet psychological research shows that creative constraints—such as negative boundaries in a brief—reduce cognitive overload and narrow focus, paradoxically enhancing creative problem-solving. In other words, an unbounded blank canvas doesn't trigger creativity; it paralyzes it.
Once I realized this, I overhauled my entire brief structure. I began integrating the concept of 'Via Negativa' (the negative way) into our editorial workflows. Defining what something is by declaring what it is not is often vastly sharper and more effective. Instead of saying 'Be playful,' specifying 'Avoid sloppy banter and never use more than two exclamation marks in a sentence' establishes a much clearer boundary in the writer's mind.
Red Lines: The Birth of the 'Never Do This' Section
I started appending a prominent 'NEVER DO THIS' section at the very bottom of my briefs. This was not a macro-strategy, but a strictly micro-tactical intervention. I drew clear barriers around phrasing habits, headline structures, and word choices.
For instance, in copy written for tech brands, I instituted the rule: 'Do not open with generic phrases like In today’s digitalizing world.' The moment you set this constraint, the writer is forced to devise a sharper, more direct, and more striking hook. Stripping away that generic crutch immediately catalyzes their creativity.
Another counter-example: the directive to 'praise the brand.' Whenever we handed down this instruction, writers defaulted to hyper-inflated, unconvincing adjectives. Phrases like 'industry-leading' and 'unrivaled technology' cluttered every draft. Instead, we injected this negative criterion into the brief: 'Do not disparage competitors, and do not use superlatives like best, only, or flawless.' Working under this condition, the writer was forced to highlight real benefits and concrete data instead of hiding behind empty adjectives. Tone of voice was protected not by what we added, but by what we excluded.
A Workshop Practice That Eliminates Revision Cycles
Naturally, this approach carries its own risk. If you rely solely on negative constraints without offering any positive vision, writers may produce overly cautious, sterile, or robotic copy. Negative constraints must serve as fences around a positive vision—not as the vision itself. Once you strike this balance, the endless cycle of editorial revisions stops abruptly. Anticipating unwanted outcomes in the brief upfront strips away the classic excuse: 'I didn't know you didn't want that.'
If you want to carve out genuine character in your copy, you must sculpt it. Chisel away the excess, the clichés, and the subtle tropes your brand despises before drafting even begins.
Here is the single transferable rule to bring back to your workshop: right before handing off a brief to a writer, pause and ask yourself: 'What do I strictly NOT want this copy to look like?' Take the 3 most critical answers and list them under a 'Red Lines' section. You'll find that within clearly defined boundaries, the writer works far more freely, and the resulting copy holds far more distinct character.
