Actually, one of the courses I took in college (1970s) was "Scientific Observational Analysis" where we had to learn to develop "trained observational skills". The head of our department (a renowned figure in our field) stressed to us that "if you can see it, hear it, smell it or otherwise sense it, it is likely real. If you can't measure it, you need to develop the method of analysis and measurement." He also stressed the reality of not getting funded to research something if there wasn't a financial end to it, explaining why so many things simply don't get serious study. It was an enlightening ten week course where we had to come to understand biases, how to work with them and understand their impact on our observations, as well as understanding what was needed to trust our observations and when to question them.
