yes. That is exactly what I am saying. only, I say weither or not she likes you with a probability not with certainty, I dont have neough info to be certain. But we can make predictions given this probabilistic information on what is more likely to be the case. If you dont beleive me, then you must really be stupid, becuase making accurate predictions is what probability theory has been doing for a VERY LONG time. And by the way, Im not a troll, Im actually trying to help you out by helping you determine what the situation was likely to be (a group of girls that didnt like you, or ones that did but got shy). Maybe your abnormal, but most people would be happy to know which situation it really was, and someone who can analyze it using inductive logic (which never lies) would be of great help.newhotness said:oic, you actually BELIEVE that you can mathemetically prove whether a girl you've never seen is attracted to a guy you've never seen. Dude, do you have any idea how stupid you sound?! I call troll here.
I dont have to know what you look like, becuase in my calculation I cover all possible scenarios good looking or ugly, and their probabilities. again, Inductive logic never lies, and is useful.
first, lets look at the probability of the evidence (girls staring) given the 2 possible hypothesis:
p(girls staring if she likes you)=.7
p(girls staring if she does NOT like you)=.03 (3% of the time, for some random reason, a girl will stair at you, maybe you look like an old friend, many reasons, etc.)
Id say these are very fair assumptions, and the true probabilities wont be off by much. SO my calculations will still be reasonably accurate.
lets look at 2 ends of the spectrum, on one end, your very ugly.
If your very ugly, then:
p(girl liking you)=.001
p(girl NOT liking you)=.999
if this scenario were true, then its unlikely a girl will like you, though a small percent of the time, youll meet some women who are weird, and will like you.
p(girl liking you given the fact that shes staring)=p(girl liking you)*p(girl staring if she likes you)/[p(girl liking you)*p(girl staring if she likes you)+p(girl NOT liking you)*p(girl staring if she does NOT like you)]
which is:
p(girl liking you given shes stairing)=.001*.7/[.001*/7+.999*.03]=.0007/.03067=.02282
so there you have it, if your real ugly, the probability of a girl liking you is.02282 given that she is staring at you. or thats a 2.382% chance she likes you. so if your ugly, it was just one of those weird situations where they stair for some random reason.
Now to the other end of the spectrum:
If your really good looking, the probability of a girl liking you and finding you hot is alittle more favorable, lol:
p(girl liking you)=.99
p(girl NOT liking you)=.01
So if your attractive, and a girl is staring at you, the probability of her actually liking you is:
.99*.7/[.99*.7+.01*.03]=.693/.6933=.9995
so if your really good looking, and a girl is staring at you, theres a .9995 probability, or a 99.95% chance that shes staring becuase she likes you.
Now, I dont know what you look like, I dont know if your ugly, or if your good looking, but thats okay, I can still get a prediction by using the probability that you are attractive vs ugly:
Theres far more ugly people out there than attractive, so Id say its fair to say theres a .1 probability that your attractive, and a .9 probability that you are ugly. so with this info, and the calculations I did above assuming we knew with certainty if your ugly or attractive, the probability of a girl liking you given that she is stairing =
p(your attractive)*p(girl likes you if we know youre atttractive)/[p(youre attractive)*p(girl likes you if we know youre attractive and shes staring)+P(that youre ugly)*p(a girl liking you if we know you are ugly and shes stairing)]=
.1*.9995/[.1*.9995+.9*.02282]=.09995/.120488=.8295
so theres a .8295 probability, or 82.95% chance that the girls liked you given that they were stairing, and that your attractive with a 10% chance, and ugly with a 90% chance. This prediction would change If I were to get more info about you, If I were to know with certainty wich you really are (ugly or attractive). But given the info I have available, the most likely situation is that they did in fact like you, and for just some unknown reason, acted cold (all this with a 83.95% chance). Even If I change some of my assumptions alittle, my prediction wont change much. THings are favoring you becuase given my assumption of 3%; its still too uncommon for women to stair for some unknown random reason. (a 3% chance) if this were to go up to say 10% chance of random stairing (which is probably too high), it still wouldnt be common enough to make it so its more likely that they were just stairing.
But this would all change if we found out that you were ugly (I would gain more info, thus a decrease in uncertainty). Hope this helps. I aint no troll. Just using my math to help you figure what the situation really was. so maybe youll know that girls are acting cold, and maybe you could use that to your advantage. Bust on them next time for it, use it as an opener.
