This is amazing analysis, presentation, and has a call to action at the end. Some of this guys other stuff: https://tobias.cc/reading
The only point I'd add is that it's not handling time evolution in wicked problems quite right. Agree that the noisy room is distorting the world in exactly the ways described. But what if we've been in there so long, and the world has become so distorted.. that reality itself slides towards the once-extreme positions? Easiest to see this with climate-change controversy since that is the way that sort of thing happens, regardless of whether you think it's happened yet. Cascade, phase change, and collapse don't just call a truce.
So you have to anticipate that, acknowledging the pessimist is actually right, and that systems are a real bitch. Then you point out that if we're already doomed, we have nothing to lose nothing by trying. Systems are complex after all, that's the whole problem.. so if we miscalculated on the doom, then bothering to try actually saves us. Checkmate pessimists.
