Well that and it’s hard to distinguish if you’re early in exponential growth or linear. Also exponential growth does hit some kind of ceiling relatively quickly.

I think that’s an easier explanation for why we’re biased against it that isn’t necessarily tied to why the brain uses a logarithmic response curve. The latter could be because it provides better dampening to random excitations (ie the brain doesn’t have to expend as much energy dealing with them at the cost of missing signal in lower energy levels). Of course it could be this is why we’re bad with exponential but that seems like a larger leap to make.
