I just read "Thanks for the Fishes" and extracted the term "Pretzel logic". I'm keeping that one. I also watched several of Hans Rosling lectures. Applying pretzel logic to Hans would not be fair, but perhaps telling. I want to argue against his claim that the earth can sustain 10 billion souls - and will get there soon and stop growing. My pretzel logic says dictators and rebels will alter the Rosling models and will reset the clock with violence, and that this Armageddon is close at hand, and at a scale that even space traveling dolphins cannot escape. I contend that my investment in Elons electric car and solar roof wont see a payout, or move the needle in populations or future violence.
