Actually, there are a lot of good arguments for logistic growth. The only ones for linear or sublinear I’ve heard are not strong and mostly take as an implicit assumption “those alarmists and their exponential growth! They probably didn’t even consider that it could be a slower, more incremental growth” instead of actual fully-fledged arguments.
There’s also a meta-argument that I have yet to hear reproduced in anti-alarmist sentiments. Which case demands more attention, if it does happen? If there’s a 5% chance of the growth being exponential, how much attention should we devote to that case, where the impact is much higher than linear or sublinear growth. This is such a big deal - it’s like Pascal’s wager but with a real occurrence that I believe most would admit has at least a small chance of happening.
Apologies for any brashness coming across. I’m still figuring out how to communicate effectively about a thing I feel a lot of emotions when thinking about.
