Not everyone would agree that “I want it to work” is a correct restatement of deontic modality. (The one I use when wanting to avoid the ambiguity of “should” is “it had better work”.)
Yes, that is a better way of phrasing it. Changed.
That effect is due to the fact that you're forced to use your System 2. It probably disappears after you become too fluent in the language (for example, FWIW, I don't ‘feel’ that happening with English).
Unfortunately, this seems likely.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
