While "mental energy reserve" is not a standard term, "decision fatigue" is, and is basically the same idea.

Eh, "mental energy reserve" seems to be used like "ego depletion" which doesn't have a great pedigree iirc.

Studies by Dweck, famous for Growth Mindset, and others point to "ego depletion" simply being a reflection of people's beliefs (My willpower is limited) as opposed to an actual resource that gets depleted.

Yes, I mean it in a similar way to the idea of "decision fatigue", but more broadly about all kinds of cognitive tasks.
