In practice, I usually encounter a vocal minority who happily ignores the fact that the sigmoid even exists, and a larger group who thinks that leveling off must be imminent and the trend can possibly continue much longer.
I suspect that most people see what they want to see in models, rather than actually evaluating the models.
I’m curious: was there a particular (set of) sigmoid(s) you had in mind when writing this post? And particular opinions about them you haven’t seen reflected in discussions?
No. I just see exponential models literally ever week and they disappointment me because they are leaving out half the model without even a nod to the fact they are doing this. It generally feels like the authors of models are failing to even consider the possibility that the growth of something will end.
