Hi, David. I was very happy when I read

I work in government and am interested in practical applications of rational thinking in large and complex organisations.

A huge amount of people here have math/computing/science majors and/or jobs. I'm in the same basket as you, though - very interested in the applications of rationality, but with almost no education relevant to it. I'm currently stuck between politics and academia (in psychology, politics, economics maybe?) as a career choice, but either way...

And we need that - people from outside the field, who extend the ideas into other areas of society, whether we understand it all as in-depth or not.

So best of luck to you! And as Alexandros says, don't hesitate to put a post in the discussion forum with any progress, problems or anything of interest you come across in your quest. I'll be keeping an eye out for it.
