It is an issue. There's heavy overlap between analytical approaches to regarding other human beings and psychopathy. That's what the "creepy" signal, in part, is signaling. It's "creepy" in a there's-a-spider-wearing-a-human-face-looking-at-me sense - human beings don't do that kind of thing, thus, you can't be a human being. As a rule, you don't want to communicate that you're not a human being. There are... severe social recriminations for doing so.
Intimidating somebody on those grounds is like having the spider pull its human face off and stare at you with mandibles clicking. It's no longer concerned with looking human; you're now food. So no, it's not something you want to do, in any case, including when looking for other "spiders wearing human faces". If you're merely analytical, you're sending the wrong signals.
If you think about other human beings analytically, and want to signal that to find other people who think about other human beings analytically, there are socially safer signals to use. Cynicism, for example.

Not sure how true this is. It's a trope, to be sure, thanks partly to Hannibal Lecter and his various imitators. But I haven't seen much in the wild to show that analytical thinking about other people is well correlated even with basic lack of empathy towards them, let alone full-blown psychopathy.
(Lack of sympathy, sure, but that points towards a cluster of personalities more in the neighborhood of autism or Asperger syndrome. Perhaps what's going on in pop culture is some sort of outgroup homogeneity/all-weird-people-are-equal effect.)
If you have a crush on someone you usually want to find out if they have one on you too. In my opinion outright asking them is often not a good solution, because if they don't have a crush on you yet it decreases the chance of this ever happening if they know you have one. This believe is based on what I read about love psychology. Hovever I don't really want to discuss the option of outright asking them in this thread, therefore I have not elaborated further how I got to this believe.
The alternative to asking them is trying to interpret signals that they might give you. However to know how many signals you need before you should believe that they are in love with you, you would need the prior. I have not been able to find anything about the prior of someone being in love with you. Therefore my Idea is to do a survey in order to find out how likely it is that a person you know has a crush on you. The plan is to ask the person taking the survey how many people they know well enough to possibly have a crush on them and how many people they actually have a crush on.
I have created a Survey for this and would be really happy if you would participate.
The next stepp would be to discuss how certain signals a person can give you raise the probability of them having a crush on you. That part is quite difficult. I think probably the best way would be to check how your friends react to certain situations and what body language they show you and then, if you find out someone has a crush on you, to look up what he did differently from people who are merely your friends. I am currently not in a good position to do this experiment but if someone wants to try or has results about this to share please do so. However I think this part is less important than finding the prior, because most people have at least a general idea about what certain signals mean from personal experience while at least I have no idea at all what the prior might be.
