AI term to know: contrastive negation. It's when AI overuses the "not just this, but this" sentence structure. Once you see it, you won't be able to unsee it.
Here's the pattern: the writing tells you what something is not, before telling you what it is. The structure forces you as the reader to process the negative before you reach the substance, and worse, it makes you think bad things you may not have otherwise thought.
Watch for it in writing, AI or human-drafted. AI models do it because the AI thinks the sentence structure appears smart and sophisticated, which, ironically, makes the writing sound less sophisticated and smart.
A few examples in my feed last week:
1. "The future of legal practice isn't just better tools to make ourselves better - it's in the creation of digital colleagues."
2. "It wasn't just a role – it was the beginning of the most significant growth of my career."
3. "Dropbox Paper is more than a doc - it's a co-editing tool that brings creation and coordination together in one place."
4. "Joining Harvey hasn't just been a new role. It's been an opportunity to help shape how AI is adopted." (Yes, Harvey is a competitor. Yes, the person who posted this probably thought you couldn't tell it was AI-generated.)
5. "This new space is more than just offices. It's where we connect and collaborate."
6. "[Legora] is not about appearing modern for the sake of it, it's about genuinely modernising how we work." (Doesn't this ad copy just make you think Legora just wants to appear modern for the sake of it?)
You get the idea.
The fix is simple! Lead with what the thing is. Delete the defensive framing. If you must contrast, do it in detail and in a non-obvious way, after you've introduced the meat of what you're saying.
"The future of legal practice lies in digital colleagues."
"This role launched the most significant growth of my career."
"Dropbox Paper brings creation and coordination together in one co-editing workspace."
At GC AI, we've done a lot of work to reduce this pattern in our output. It still happens, but much less than off-the-shelf models or inferior AI tools.
My advice: fix this issue when you see it in AI text, and now that you know about it, watch for it and develop your writing taste. Do that before shipping your writing. Or, use GC AI?
PS - Don't even get me started on emdashes lol.
