In some professions saying that you "love you work" is a signal of a good employee. So I would expect some dishonesty in self-reporting.
How could we ask the question to reduce this signalling? I imagine only silly questions like this:
Imagine that for some external reasons your workplace must be closed for two weeks. During those two weeks you will receive your normal salary, and those two weeks will not be taken from your holidays. How does this message make you feel?
a) awesome!
b) mildly happy
c) neutral
d) mildly sad
e) depressed
On the second thought, is this question really silly, or does it show our true preferences? And the silliness is merely a reflection of dissonance between our professed values and real values.
I think it genuinely shows our preferences. Of course, I also would be fairly neutral about this (and would probably seek other work for those two weeks).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
