Gross. It sounds like a total failure to correctly model reality.

Like measuring how blue the sky is, based on how much "blue" is left in the universe. The idea they attempt to quantify is improperly described in terms of qualities. e.g. Do colors even work that way?

(...and keep your planck unit, M theory, quantum field eigenstate, history-of-the-big-bang, age of the universe remarks away from this hypothetical example, please. You know what I mean when I describe the sky as either blue or not blue in the colloquial sense.)

Well of course it sounds ridiculous when you use an absurd analogy. A more reasonable analogy was something like muscle fatigue, or even mental fatigue, and it seems reasonable to believe that willpower can be depleted in a similar way. In fact, there were many published studies consistent with this hypothesis (as the abstract states).

I disagree.
