If you suggest the country; maybe some more relevant advice can be given.
Try meetup; check your local library for local group events. Look around for community notice boards. The problem of community finding is a hard one; for both communities looking to attract people; and people looking to find their community; it is as yet only now being solved partially by things like meetup.
There are also charitable volunteering opportunities that I have found will tend to host interesting people to interact with. Consider looking around for these groups too.

Does this help?
I am in America.
Meetup, library boards, etc. are useful, but I don't need more groups, I need to know which of my many choices are likely to be useful. I'd like to do better than showing up at vaguely interesting meetups and seeing if they happen to be comprised of interesting people... Although this basically is what I have been doing. It is not a motivating task.

This thread is for asking the rationalist community for practical advice. It's inspired by the stupid questions series, but with an explicit focus on instrumental rationality.
Questions ranging from easy ("this is probably trivial for half the people on this site") to hard ("maybe someone here has a good answer, but probably not") are welcome. However, please stick to problems that you actually face or anticipate facing soon, not hypotheticals.
As with the stupid questions thread, don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better, and please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
