1. I heard in Science they say the better the "predictive power" of a theory/principle/model, the better it is for technology. In the hard sciences, mathematical models maximize this predictive power, so if one was to look at graphs/plots/other data visualization, maybe one could maximize their potential if general patterns are found? I'm just curious what you would say about that, and why? (remember, not all equations in the hard sciences are exact predictions but often they have probability within a certain range and are still falsifiable and good for technology)
Admittedly my experience in this area is not based on scientific method but I would guess, based on that experience, that the added predictive power of any equations you may come up with above that of standard observation of signals would be relatively minimal. The number of unknown variables when speaking with a stranger (specifically the elements of the individual persons psychological makeup) is quite large. I would say that attempting to deduce a persons interest based solely on 'flirtation equations' would be akin to trying to predict the weather with only the temperature and humidity without benefit of wind direction, wind speed, cloud concentration, ect. Specific and precise equations may be better than a rough guess but not by much, in my personal estimation.

2. It can make it more quantifiable in showing that non-verbal behaviors are related to interest, even if not exact. So if someone in the other discussion forum at PhysicsForums later on says body language isn't related to interest at all, I'd be able to whip out an equation to show and make it quantitative. That would make it more rigorous in Scientific Method?
I am pretty sure I read the thread you are referring to here and you seem rather stuck on it. ;-)
I do not think anyone believes that body language
is not a decent gauge of interest but rather that it is not a very
precise one. You are relating the usefulness of such equations to those of Galileo and Newton and I think that people are simply warning you that human bodies are not as predictable as apples and planets. That body the moon is more constant than the one belonging to Juliet.

I absolutely agree.

I'm just under the impression that being better able to read whether she'd be receptive would increase the likelihood of trying to talk to someone who'd possibly get somewhere. Do you think I'd also have more confidence because instead of worrying about impressing, I'd mostly be going after those who'd be receptive?
I think that 'rules of thumb' would be sufficient and, as noted, not much less predictive than equations.
As for confidence... It seems, and correct me if I am wrong, that you have aspergers or something similar? Perhaps our brains work differently, so you may not have the same emotional response as I, but my confidence has come more from experience than study. I am a people watcher myself, and have been since I was a small child, so I felt that I had a good handle on what women are like but my confidence with regard to women (what little I have) did not come until I actually dove in and gained myself some hands on experience... so to speak. Similarly you could not have confidence in your equations until successfully applied.
Now, no offense, it seems to me that you are displacing the issue here. Rather than attempting to learn in the more traditional method you are focusing on study which is an internal and eminently more controllable process which maintains your separation from the social process that is less predictable and which you seem to find uncomfortable. You may want to consider that the comfort and confidence issues when you finally attempt to apply your studies will not be eliminated. You seem to be engaged in a sort of 'productive procrastination'.

As far as learning from trial and error, do you think I'd need something to try in the first place for that to work? Just like there are some who have learning disorders/dyslexia, wouldn't some neurologically have trouble picking up on these things naturally, but be able to learn similar to how you'd learn to play the piano or how those with learning disorders/dyslexia can be tutored?
In order to learn from trial and error, wouldn't you need to learn how to read body language and the person for you to pick up on what works? So what do you think about needing a starting point where body language is learned? Otherwise, wouldn't you just be at square one again?
As above, I think rules of thumb should be sufficient. Regardless of any syndromes or disorders a person has basic study into human behavior and body language should make for a sufficient base to work from with experience. Think of body language as being similar to organic vocal language rather than static maths. The meaning (value) of any particular word (variable) is better learned through rules of thumb and experience with the language than by constructing probability matrices.
