Hmmm...
I've done a bit of reading on facial expressions. I'm starting to suspect that interpreting subtle emotions in the human face is very similar to interpreting meanings in artwork. For instance, many people would extract different meanings from a painting: none of them would be "wrong" as such, but would just have different perspectives and personal interpretations of the art. Interpreting human emotions and motives is not an exact thing. That's why I doubt that emotional expression could ever be measured quantitatively.
Different people probably see the world and each other through different perceptual "lenses". Behaviour that might irritate one person may not irritate another. Different people's different frames of references, temperaments and prior social experiences probably do affect their interpretations and reactions to different social situations.
People may also try to deceive one another by masking/suppressing their true feelings by muting/substituting one facial expression for another. Others may not use such a large repertoire of facial expressions due to their underlying personalities. Social situations can quickly become complex.
There's also the issue of social context. A wrinkled nose could mean: disgust, smelling something or an itchy nose. That's why it's important to attend to the physical/verbal context of the situation as well as what the whole body is doing.
Perhaps body language is an art-form and social communication is a kind of "dance"?
Yes, some of it is subjective. One thing to consider is a lot of it may also be objective. One thing I found interesting is there's quite a bit of research that many facial expressions are universal across cultures, and to those even among those born blind! So there's more to it than just what we learn from operant conditioning/culture. However, what does differ between cultures, is intensity and when it's socially appropriate to show off your emotions (ex, East Asians vs. the United States vs. Latin American countries).
Here's something I found interesting on the Universality of Facial Expressions, by the American Psychological Association.

It looked at the 2004 Olympics and also Paralympics and compared the blind athletes to those who could see, and there's universality. Interesting.
Something cool I came across is the Facial Action Coding System, which is a standardized way to measure facial expressions by the facial muscles used
http://en.wikipedia.org/wiki/Facial_Act ... ing_System The coding system for the units is supposed to be independent of interpretation, although it doesn't provide an interpretation of the expression. However, when I look at the details between many of these online facial expressions tests, it doesn't say they use that but rather use a panel of judges to decide if facial expressions are accurate. So it may not be as accurate.
