There are plenty of writers groups out there. The biggest hurdle is going to be getting these people to think of themselves as writers.
Your best bet is to serve as a mentor to them, and help them find other mentors in the community. Many writers would LOVE to be mentors. For one thing, it’s an ego boost to them — “Wow, I’m good at enough at what I do that I can help someone else do it too!” — because we have notoriously fragile egos and low expectations about our own abilities.

Depending on where you are, there may already be writers groups they can either join, or you can talk to about finding mentors.

@klg007 Your best bet is to encourage them to write about anything – even their favorite hobbies.  Sometimes even just encouraging them to start commenting on blogs or forums can help because writers will generally find themselves writing longer responses than the average person, and any little bit of writing can help inspire them to do more.

@klg007 Not to be contrarian (because I do agree with the foregoing comments/suggestions), but I do find the joint use of uninspired and talented a bit odd. I say this because talent is often found through expression (be it in science, arts, or any other arena). So, if you (or any other person) judge these individuals as talented, then they’ve already overcome the most daunting obstacle of all. Presumably, they’ve already demonstrated that they have something to say. Perhaps, the issue now lies in their medium of expression, which as you say may be unconventional.  As any successful artist will attest, “unconventional” goes with the territory, so it’s not necessarily a problem, especially if the individual is talented. Being unconventional might be the key to discovering their niche.

Perhaps the real issue is not lack of inspiration, but one of finding the right fit for their talent. I will dare to say, we’ve all been there.  Sometimes, it takes trial and error to find the right setting. Always, it takes self-confidence and perseverance — both of which can bloom with the help of a trusted mentor or community — regardless of the phase of the individual’s career.

As a subscriber to writerswin, I can vouch for the quality and information. And encouraging people to put their thoughts down in words is never a waste of time – for you or them. Good thread, Kenneth. Thanks for starting it. It’ll be fun watching it grow.
