How do I tell my colleagues to stop contributing unverified AI output without creating tension between us?
I've never did that so far because I feel like I am either exposing their serious lack of professionalism or, if I wrongly assumed it was AI, I am plainly telling them that their work looks like bad AI slop.
Make them realise they're replacing themselves if they continue down that path. "What value do you have if you're just acting as a pipe to the AI?"
That's the asymmetry of the problem: Writing with AI delegates the thinking to the reader as well as all the risk for correcting it.
I've found success having sidebar conversations with the colleague (e.g., not in the main public thread where they pasted slop), explaining why it was disruptive and suggesting how they might alter their behavior. It may also be useful to see if you can propose or contribute to a broader policy on appropriate AI use/contribution with AI, and leverage that policy as the conversation justification?
You don’t. You keep these arguments handy for ignoring their output until it’s germane.
Pattern rather than person? General team reviews or the like. As long as it's not tech leadership pressing for it..
Embrace the tension. Tension is human.
The most interesting incident for me is having someone take our Discourse thread, paste it into AI to validate their feelings being hurt (I took a follow up prompt to go full sycophancy), and then posting the response back that lambasted me. The mods handled that one before I was aware, but I then did the same thing, giving different prompts, and never sharing the output. It was an intriguing experience and exploration. I've since been even more mindful of my writing, sometimes using similar prompts to adjust my tone or call me out. I still write the first pass myself, rarely relying on AI for editing.
The person being targeted just prompted the same AI with "Which user has thin skin" and instantly the AI turn on the other person. Then the moderators got involved and told the first guy to stop using AI as a genital pleaser.
