I don’t see why this would “supersede” other models. I don’t have to test it in my own case, because I already know that I am less willing to work if I did not expect to have to work. That doesn’t mean that willpower is not a consumable resource. For example, you can compare it with money. If I go out and expect to spend $20, I might tell people, “I can’t afford that,” if the thing is going to cost $100. But if I had expected it to cost $100, I might have spent that amount. None of that shows that money is not a consumable resource.
Using your money analogy, what I’m saying above is that if you expect the item to cost $20, you will go to the shop with only $20 or $25 in your wallet. So you won’t buy the item if it costs $100.
This theory is compatible with willpower being expendable—obviously, you can’t carry more cash in your wallet than the total amount you own.
So it is a more detailed model, in which you can be short of money in two ways: you can’t afford this at all, or you didn’t think to have that much cash on you when you left the house.
