A lot of your post is wrong. By just reading the initial bit, emotions aren't fuzzy. Ekman's work and many others were very based on quantifying them rather than qualitatively identifying them. You should look up the work is done for clinical psychology with emotion recognition and the muscle system for measuring facial movements. You'll see it wasn't so fuzzy as one may think. It's very precise. > In general, psychology doesn't seem to be based on many of the lessons acquired in the physical sciences over a very long period of time, and there doesn't seem to be much math involved. This is just so wrong. Ten years were spent developing a mathematical system called the Facial Action Coding System: https://en.wikipedia.org/wiki/Facial_Action_Coding_System https://en.wikipedia.org/wiki/Facial_Action_Coding_System. This system is used to add together all the muscle movements of the face. When this is done, you can discern from the muscle movements what emotion is being displayed. Emotion science is known to be a field of psychology that really thrives from science. I can't think of any other field where BA's and BSc's can work together on their research and where MD's can reliably use the work they develop. There's very little fragmentation and the work each group does and contributes to the other is valuable. Emotions are so deeply tied to the sciences that you can see them occurring in the brain as you give it an MRI. The amygdala activates and registers uniquely for each of the six emotions. All basic emotions originate from the amygdala. All basic emotions are displayed universally and symmetrically (perhaps with the exception of contempt, but a whole article can be done on that), all basic emotions on the face, all basic emotions are universal, and all basic emotions register as we see other basic emotions. The last one is interesting. When it comes to clinical psychology, we can actually see patterns in emotion recognition and tie them to mental health disorders. Borderline Personality Disorder scored on par with a baseline, but they selected anger as the emotion when defaulting. Bipolar assumed more emotions were happy during mania periods and sad during depressed periods. Anti-Social saw people who failed to reach par with baseline with either failing to recognize fear or failing to recognize disgust in other individuals. On top of that, we also know that displays of emotions are important as well. Major Depression saw individuals display a wide array of emotions; almost like they were screaming for someone to see their feelings. And then, psychologists also saw Major Depressive people exhibit minimal emotions with slight movements in the upper face. These people were in a completely different segment and were at a high risk of committing suicide. We can derive from the muscle movements, the activation of the brain, how these expressions are universal, and how we can mathematically that this science is not "fuzzy". There is a lot of hard work and much consideration from all facets of research that contributes to these results.
