I know, the takeaway is so funny, because it's not actually
up to the author whether or not the solution she took would've worked. To her, "Actually Trying" and "not trying" both hinged on the success of other people helping her out. To a more hard hearted individual, the only thing that would've qualified as "Actually Trying" would've been flying out to India in person and then finding the guy first when he'd least expect it. "Actually Trying" was only determined after the fact when the result was that there was a success. If the husband coordinating with a friend hadn't worked, what then? Did he "Actually Try" if the FBI, the Consulate, and the friend were all like "we don't give a shit about this random little troll sending death threats. Did you know everyone gets death threats all the time on the Internet? Log off." What then? Is that still Actually Trying, or do we only determine that after a success? Texas Sharpshooter Fallacy, friends.
The husband was the social proof that this random junkie woman who's complaining about a guy on the opposite side of the planet was worth taking seriously. She might not have wanted to go to the cops because she didn't want to go to them, have them laugh it off and then feel both powerless and humiliated, and the conclusion is that another person who then manages the difficulty isn't even trying? Maybe not, but that's a different think from deciding that they aren't doing it because they're stuck in some old mindset.
The other example she gives is this: "These are people who could successfully launch a product in a foreign country with little instruction, but who complain that there aren’t any fun people to meet on the dating apps." Like, girl, it's not up to you whether or not there are any cool people on dating apps. There's a selection bias of who gets on dating apps going on here. You can do everything within your power and Actually Try all you want to have it be another way, but you can't really force cool people to socialize in the way that you want them to. It could be the case that there really is no one cool on those dating apps, because social climate being the way that it is means that no one feels comfortable showing their whole, unvarnished, "cool" selves and the coolest people are hidden.
At what point is someone "Actually Trying"? Is it once they've succeeded? This feels like the self help, "The Secret", "Girl, Wash Your Face" of previous eras but dressed up in the language of people who use terms like "non-zero probability", "priors", and "local optimum". The takeaway should not be that someone shouldn't try, but that the serenity prayer's most difficult part is the "wisdom to know the difference". She had the power to change this, but the wisdom to know the difference here was not guaranteed. It would be a kinder message to everyone who is in a tough spot to at least acknowledge that having a husband to vouch for her, with connections, free time, and a motivated reason to help out kind of changes to what extent she personally could be responsible for Actually Trying.
