I suspect the scientists intuition is less reliable because the scientists are acting at the limits of our understanding. Even then it is still a critical component.
For those of us writing glue code to connect services for the 100th time or a manager dealing with our 20th PIP is our intuition likely to be as faulty?
Another way to put what I think they were trying to say -
If you have a lack of knowledge, the ‘rational’ set of things to try can be so large that it’s overwhelming/impossible to actually try them. You have to pick something.
Intuition can help there (and is commonly found in almost all major discoveries), even if it isn’t necessarily right. Since it’s still more right than not listening to it.
But then you need to pay attention and do some rational analysis to verify, and then iterate.
I missed this - body language experts the world over will tell you that body language is culturally and individually unique.
Some people share similar body language for displaying certain emotions, but they are not universal.
Further you may be able to tell what some people are feeling by their body language, but there will be many many more examples where you miss the emotion.
Worse, the ones that you can get an idea of, it's very VERY rare for you to know the reason that people are in that emotive state.
edit:
This even applies to people close to you, who you think that you know.
