You must have reliable information for intuition to be reliable.
The problem is that no matter the experience(information) intuition throws up a feeling. If there is a lot of experience in that narrow area (like your machines) then it can be accurate. But, when approaching something unknown, it will still create the feeling based on possible very poor information. What is felt feels the same in both instances however and, if one spends a lot of time with the narrow (correct) intuitive feelings, they will likely weigh their intuitive ability more heavily as they have experience in being right. This means that in the unknown areas where the intuition is performing poorly, ther is a risk to overweigh its judgement.
