Hello friends,

I’m in Japan for the first time in a decade.

Many months ago, a bunch of us decided to do a short walk together and chose a section of the Kumano Kodo to do it in. Over the intervening year, other things happened so that I came to Japan early for meetings to ready the ground for doing more work in Southeast Asia now that I’m based full-time in Singapore. But also to opportunistically hang out for a few days with some other old friends who happen to also be here.

Here are some of the things I noticed after ten years away:

Row 1, L-R: A weird, bulbous way of building an interlocking stone wall; characteristically unlavish but careful and fine construction on a garage post; one of an endless series of umbrella holders outside houses and places of business; the flying fairybear logo of the Tokyo neighbourhood police posts.

Row 2, L-R: Outside the Kamiyama-cho sorting station of Yamato, one of Japan’s superb logistics companies; a loop pedestrian overhead crossing connecting all four corners of a busy intersection; the omnipresence of functional netting; the ubiquity of absurdly precise cast concrete construction.

Row 3, L-R: Concertina gates for driveways; facades covered in sheets of small tiles; 3D metal mesh doormats; construction sites with aggressive noise mitigation and measurement.

I’ve been prototyping an AI tool that uses Socratic mirroring to build a reasoning scaffold that helps users develop stronger arguments. Testing a fully functioning prototype across universities, corporations, startups, and government shows that the method generalises: Users doing real work with real stakes find it useful enough to want their institutions to provide it. Theoretical innovation in meaningmaking translates directly into practically useful meaningmaking tools.

If you’re interested in testing the tool and/or learning more about it as it develops, sign up here. The tool is fully functional, so testers can benefit by refining an actual argument they want to make (e.g., for a paper in a class, a policy paper for potential implementation, a startup business plan, or a strategy proposal for management).
