Teal = Metamodern (right?) 
Teal = Yellow (in old skool spiral dynamics)
Works for me. Others prefer fine distinctions, as has been aired out at great length in a variety of settings. Apart from color selection, the best work I have seen lately in stage theory is the recent contribution by Brendan Graham Dempsey. What is Hierarchical Complexity?
Whatâs good about shifting the analysis to Kurt Fischerâs Dynamic Skills Theory is that it disaggregates paradigms/vMemes into component skills and behaviors. That resonates with my experience teaching a wide variety of âmodernâ math, science, technology, and business topics over the years. All of that is âmodernâ, but itâs not like Newtonian physics and double entry bookkeeping are the same things. There is an underlying quantizing sensibility that goes with all of it, but none the less, itâs quite possible for people to take a âmodernâ outlook in some special skill set or another, while remaining thoroughly premodern in other respects. Moreover, âpostmodernâ attitudes about social justice are quite prevalent among students and faculty who are not really masters of the full spectrum of modernity. All of this factors quite a bit into the âmean greenâ phenomenon. which I would describe roughly as postmodern values articulated in very premodern ways.
So from the Dempsey article, yellow/teal is basically systems of systems. I ran a two-prompt Gemini session on the correlation between stage theory, social change, and the Fischer model and got a pretty plausible result. This statement is a summary:
âApplying the Fischer Model of Skill Development (specifically Kurt Fischerâs Dynamic Skill Theory) to the definition of Modernity in the Second Renaissance Whitepaper reveals that Modernity is not just a historical era, but a specific stage of collective cognitive and cultural complexity.â
Full session here. It suggests yellow/teal as âprincipled reasoningâ (beyond modernityâs characteristically âabstract reasoningâ) That strikes me as a desirable target to aim for.
