People's proclivity to respond is called self-selection bias, and it's
tackled with the question "What is the main reason you are taking this
survey?", if people respond "Somebody is pushing me", we can identify
people without such proclivity and measure the bias of self-selected
As for non-response bias, I am aware of it, and I am doing all I can
to mitigate it.

We don't need to know the exact non-response rate, studies have shown
it's not that important.
As a result of these and other such recent findings, it now seems
clear that a low response rate does not guarantee lower survey
accuracy and instead simply indicates a risk of lower accuracy.
Now. Do you actually have a suggestion?
