On the other hand: Perception of change might not be linear but logarithmic.

(= it might take an order of magnitude of improvements to be perceived as a substantial upgrade)

So the perceived rate of change might be linear.

It's definitely true for some things such as wealth:

- $2000 is a lot of you have $1000.

- It's a substantial improvement of you have $10000.

- It's not a lot you have $1m

- It does not matter if you have $1b

[varjag]

$2000 is not substantial over $1b on the linear scale

[Garlef]

2k is the same on the linear scale no matter where you are. that's what the linear scale is about.

you're already interpreting this on the log scale
