This type of Hollywood Rationality is explicitly listed in TV Tropes under "Straw Vulcan" (failure to understand that goal achievement may require locally backward steps). I haven't encountered anyone who explicitly associates that with LW in particular, and anyone who's taken an introductory AI course should know better than to think a backward step is beyond computation, logic, Bayesian agents, etc.
I think we could apply the lessons, anyway, but Munroe might have our community in mind specifically. The alt-text refers to emotional biases. I'm just curious if others got the same impression.
