It looks like a conversation with a person I haven't talked to in something that isn't either long enough for them to forget about me or someone close I haven't talked to in some time.
But let's be pedantic and you'll probably like this or the autism stereotypes aren't true, here's a few scenarios:
Your example will probably work on category 1. Category 2 MIGHT go along, although a simple hi is rather generic and therefore is more of a lottery bet than a sure bet. I can't tell how category 3 will respond, but probably not better than category 2.
Consider how you'd feel about the introductory messages if you were from each of those scenarios.
We could also dive into sub-scenarios, tailored to specific optimisations or lack of them. Such as my fashion choices, how I live, people I hang out with, etc. Although it's dubious how much they matter since all of this is my unresearched model in my head about online messaging.
You are correct, (some of) the autism stereotypes are true in my case!
There's a lot of data and research on what makes people successful at online dating, but I don't know anyone who actually tried to wholeheartedly apply this to themselves. I decided to be that person: I implemented lessons from data, economics, game theory and of course rationality in my profile and strategy and OkCupid. Shockingly, it worked! I got a lot of great dates, learned a ton and found the love of my life. I didn't expect dating to be my "rationalist win", but it happened.
Here's the first part of the story, I hope you'll find some useful tips and maybe a dollop of inspiration among all the silly jokes.
P.S.
Does anyone know who curates the "Latest on rationality blogs" toolbar? What are the requirements to be included?
