Advice for an isolated Rationalist?

As a stop-gap measure, until you find some rationalist meat friends, you can gain some immediacy from the freenode IRC #lesswrong channel. YMMV.

I would try asking members of the Melbourne meet-up if any of them had an interest to meet at either your house, their house, or at a chosen point in between at some point. There is a chance that you'll find out that some of them are less than 90 minutes away, and another chance some of them do not live less than 90 minutes away, but might have the time to make the drive over, particularly if you try to meet them at some sort of halfway point.

Well, your biggest step was to even find and join this site. I'm in a similar predicament at the moment, and I JUST found LessWrong last week.

I supposes you could find similar minded people if you try to join community groups/projects that you have interest in. Try sharing your ideas/thoughts on the various social media sites. I'm sure you won't get a bunch of responses if you have friends similar to mine, and the responses you do get will be sparse and not so worthwhile - but it's a great way to refine your thinking.

And as others have suggested, try contacting those who plan on going to the Melbourne meetup and see if there is a chance a future meetup could be organized closer to you.

Best of luck.

I can confidently say that many of the ideas on in this community have done much to better my life

Could you give some examples?

Consider setting up online LW meetups via say google hangouts. From previous experience I think this can work for groups no larger than 8 if two or three participants already know each other.

Reach out to existing rationalists past and present, and start trying to develop semi-original rationality skills building on your personal strengths, and the sorts of things you pay attention to.

I got a lot out of sporadically talking with people in the rationality community over Skype and phone and the like, and there are a lot of really good autobiographies by fairly important people. There really is a lot of information in the community that just isn't on LW, or in most of the meetups.

Feel free to PM me if you're interested in emailing back and forth about this.

I'm in a similar situation. My nearest meetup is in Melbourne, too. But for me Melbourne is 9 hours' drive away. I'm not just looking for friends - of which I have a few already, I'm also looking for a partner. Of all the woman I've met in the last decade (taken or otherwise), I've only met one who would not be turned off by this stuff and that one was taken.

On the friends front, I've sent messages to the two Less Wrong members that I could find who live in Adelaide, but no response yet. On the partner front, I recently had a date with a woman who asked me what I believed about the beginning of the world as an atheist. I said I open the science book and see what it says and then reread it every few years to get up to date. This led into a discussion of rationality, after which things cooled off. I haven't heard back from her since then.

So do I need to keep my mouth shut about the things I think about? Or just wait for the statistically unlikely occurrence of a rationalist, un-taken woman who is also interested in me?

How old are you, and what's your life situation like? For example, if you're about to start college, you may be able to pick one that would have some intelligent, like-minded people around, or if you're in college right now you could think about transferring to a different one, or whatever.

Besides that, I don't know. What do you mean you don't have the social support to back you up? We're here, aren't we? It may not be as good as knowing people IRL, but it's not that much worse if you're just talking academically. And if you're looking to socialize, you don't need LW-caliber intellectuals for that.

Try to convert your non-rationalist friends.
