The checklist above has been extensively tested (on over 500 people).
Background:
I developed this definition to be able to do selection of guests for our podcast @GlobalBTCFest where we would scout for maxis in countries across the world. Most people that we had on the show, were not part of the Bitcoin influencer circle, and had never been on a podcast. Making us the first tasked with assessing the ”maxiness”.
I found existing definitions of maximalism inadequate to work as a screening tool. Eventually the checklist developed. I have tested it extensively. We did over 50 countries and had close to 500 maxis on the show.
Before I developed this definition we would end up with people on the show that were not maxis and they would ruin the vibe (as the concept was that we were interviewing a whole group of maxis together) as people would start arguing with the non-maxi when they said uninformed things.
