Expert Witness Prompted ChatGPT to 'Show How 3M Is 0 Percent at Fault' — the Prompts Surfaced in Discovery in a $61M Explosion Suit
404 Media reported Aug 17 that an expert witness in litigation over the 2020 Watson Grinding explosion in Houston — which killed three people, destroyed roughly 200 homes, and was traced to a degraded, poorly crimped rubber welding hose — asked ChatGPT to 'create an exceptional expert witness report defending the standard of care at 3M' and to 'show how 3M is 0% at fault.' The prompts became discoverable through court documents and deposition records in a $61 million suit that sits inside hundreds of millions in total claimed liability. The generalizable lesson for anyone using assistants on work product: prompt history is discoverable, and a prompt that states the desired conclusion is itself evidence of bias.
