what's unclear to me is how you identify the Real Units.

needing-to-breathe-ness is (probably) a gimme, but what are the units that will explain which route i take on my walk today? and how do you avoid defining units that aren't impressionistic once you need to rely on language and testimony to understand your research subject's mental state?

my understanding of psychological constructs is that they're earnest attempts to try and resolve this problem, even if they've led us to the tautological confusion we're in now.
