Maths and human behavior graph and formulas Can maths and psychology be connected somehow? I mean can we describe emotions and behavior by some variable or some formula that gives us same results in same situations from different persons?
I attended a seminar in which sir said that this graph can be seen as with three points we can think of it as three people and $+$ sign will say they are connected (friend or other) and $-$ sign will say disconnected (enemy or something like that or don't know each other).
Now suppose one point is girl $g$ and other two points are boys $b_1, b_2$.
Then if $g$ and $b_1$ likes each other, it's a $+$.
Also, the $b_2$ likes $g$ but $g$ does not like $b_2$, it's a $-$.
So the sign between $b_1$ & $b_2$ will become automatically $-$ from $+$ (if those two boys were friends).
But it's just an example what he explained if there are any other examples anyone know that connects human behavior and thoughts with mathematics please share.
It is much better if somebody tell me if it is possible to go with both the subjects in future, that will be great.

Yes, aspects of human behavior can certainly be modelled mathematically, at least in a statistical sense (telling an "average" behavior around which there are fluctuations).
This requires to objectivate these aspects and measure then in a repeatable way. For instance, how can we rate "being in a good mood" ? An approach could be to count the number of smiles during an hour (assuming we can objectivate smiles sufficiently accurately ;-) ). (Now what is "$a$ likes $b$" ?)
But this is very far from the empirical and pretty naive "relationship arithmetic" that you describe. Human relations are much more subtle.
