Superrationality isn't a substitute for heroic responsibility, it's a complement. Heroic responsibility is the ability to really ask the question, "Should I break the rules in a radical effort to change the world?" Superrationality is the tool that will allow you to usually get the correct, negative answer.
ETA: When Harry first articulates the concept of heroic responsibility, it's conspicuously missing superrationality. I think that's an instance of the character not being the author. But I think it's later suggested that McGonagall could also use some heroic responsibility, and this clearly does not mean that she should be trying to take over the world.
I agree completely. McGonnagal has decision-making authority, so she is exactly the person who should be thinking in terms of absolute responsibility rather than in terms of convention.

Heroic responsibility for average humans under average conditions
I can predict at least one thing that people will say in the comments, because I've heard it hundreds of times–that Swimmer963 is a clear example of someone who should leave nursing, take the meta-level responsibility, and do something higher impact for the usual. Because she's smart. Because she's rational. Whatever.
Fine. This post isn't about me. Whether I like it or not, the concept of heroic responsibility is now a part of my value system, and I probably am going to leave nursing.
But what about the other nurses on my unit, the ones who are competent and motivated and curious and really care? Would familiarity with the concept of heroic responsibility help or hinder them in their work? Honestly, I predict that they would feel alienated, that they would assume I held a low opinion of them (which I don't, and I really don't want them to think that I do), and that they would flinch away and go back to the things that they were doing anyway, the role where they were comfortable–or that, if they did accept it, it would cause them to burn out. So as a consequentialist, I'm not going to tell them.
And yeah, that bothers me. Because I'm not a special snowflake. Because I want to live in a world where rationality helps everyone. Because I feel like the reason they would react that was isn't because of anything about them as people, or because heroic responsibility is a bad thing, but because I'm not able to communicate to them what I mean. Maybe stupid reasons. Still bothers me.
