Stealth attraction is a popular term in the PUA scene, and wanting to use its supposed benefits through texting is understandable (if) its claims are true.
We'll get into what it is, how you could do it through text, and alternatives that may be better suited to you.
Stealth attraction texting is a method to discreetly gauge and build a woman's interest in you. It's based on regular stealth attraction of making small "escalations" with women to see if she likes you without getting rejected. The same replies through text, with assessing interest from her responses.
However, it's essentially just another childish PUA term. Yes, gauging interest from a girl is a good idea, but that's not some powerful technique- it's just a fundamental part of meeting women.
The other part of gradually (but overtly) building her interest isn't anything new, either. After all, anyone would continually build a connection with someone they continue to spend time with (through text or not).
There's a lot more to this "technique" than just some dating 101 principles. This is where it goes off the rails.
Here's what's wrong with the regular "stealth attraction":
The good thing is you can't fully apply this "technique" to texting since you're not in person. What remains is just the basics of texting a girl, and it doesn't offer anything new.
As with every other seduction technique, the primary flaw is how it assumes women can be "gamed." As just mentioned- the intent to manipulate is bad enough, but the woman's interest in you will never be dictated by your pickup technique.
All in all, none of it's really worth the effort. It's similar to negging with not being worth the effort.
The worse part is that you may be perpetually friend-zoned by a girl. No reason to indefinitely spend time talking to a girl with the hopes of it leading to "something more" one day.
Years ago, when I was just starting to go on dates with women (but still inexperienced), I decided I would like a legitimately hot chick to be a friend. It started to seem exhausting or wrong to always be pursuing every girl at every chance available.
I didn't want to be someone who always needs to be chasing every girl I can. I figured the guy I ultimately wanted to be wouldn't always be so thirsty. That I should be able to turn down any number of opportunities without affecting how often I get laid.
The only thing is- it didn't exactly work out that way.
I certainly developed that attitude, which is great and something every guy should strive for. The problem was discovering that the 2 girls I wanted to be friends with had become interested in me...
Maybe they liked the change of pace, talking to a guy who's much more casual with them and not just trying to hook up. Not sure.
Being completely oblivious in my old nature to their signs of interest, I just stayed friends with both of them until we gradually lost contact. It did at least work out for one of them, having set her up with a buddy of mine. They've been together for 7+ years now.
This leads to the question of whether girls can be friends with guys. I don't really have an answer to this. In social circles or work circles- absolutely. However, that's not what people generally refer to when they ask this question.
I generally lead to the side of no. There are always exceptions, but in most cases, it doesn't work out. One person almost always has some interest in the other. Also, though I set out to only be friends, I doubt I would've turned them down if either had leaped up and started kissing me.
The best alternative to stealth attraction texting is not using any "technique" at all.
Understand the significance and value of texting, but realize there's no secret method.
That being said, there are some basic guidelines for what you should or shouldn't do:
Be direct yet casual if you want to ask a friend out over text. Carry a laid-back but fun attitude with most of your interactions with her.
While there is some use or truth to stealth attraction texting, it's on things you should already know (which is mainly common sense).
Use texting to build connection, have fun, and flirt- all while not taking it too seriously or wasting too much time.
