I wonder what examples would you have in mind?
It's easy to say "just be great".
I know for sure that a lot of men, significant percent of my single friends, actually tried that for years, with little to no effect. Seems like when a woman needs the man to be interesting and exciting, she wants some non-trivial specifics which are actually hard to either understand or achieve.
> So the bar is not that high.
Would you think that this whole situation the article describing happens while the bar is not that high? Do you think the problem is illusory? Or the society as a whole just doesn't know some rather simple to make and simple to understand actions?
Yes, society as a whole does not care in the least about giving people viable social "scripts" by which they might get to know each other and pursue intimacy in safe, healthy and effective ways.
(Of course, the consequences of this lack become all the more apparent when ludicrous excuses are put forth to minimize or justify serious coercive and predatory behavior. Teach people to relate to each other in better ways, and you'll also deprive dangerous predators of the excuses they like to fall back on.)
The question effectively was, do you know a smart thing the majority of the rest of people doesn't know - and that is for a problem which is older than all of us here. Seems like you believe you do but can't explain :( .
Hence, if you're going to try and show interest in a woman, do it in a way that's clearly going to be interesting, exciting and empowering to her, even if she doesn't seem to reciprocate sexually. (Which in practice means you'll need to show genuine social interest and friendship to her, combined with a modicum of sexual interest that's demonstrably connoted as non-threatening. Mostly by showing yourself off as sexually attractive and attainable, and leaving it at that. Yes, it's very unintuitive from a male POV - many males will reject this approach as weak. But a neutral assessment of strategy says it will work, and give women what they're mostly looking for.)
