Negligence means everything would have been fine if everyone involved did their duty. So I gave cases where people did their duty, got it wrong, and weren't negligent. You can imagine scenarios where they were negligent because they didn't do their duties, but I can assure you they were not since these were my imagined scenarios. In the case of these scientists who did their duty to the best of their abilities, this wasn't negligence, full stop.
