Fair enough. First, master rationalist is probably pushing it a bit too far in what's required; rather, you just need to work towards a "mind like water" state, flowing in whichever way the evidence directs it, and once you get close enough to that state the need for a true crisis of faith should disappear.
As for myself and and others who might make a claim to have no crises of faith, it's a fair question to ask if we're simply not seeing them. It's entirely possible that there are some beliefs that I have that I am unaware are so tightly held that I don't even see them as beliefs, but as truths about the world. However, I have had many experiences which you might identify as a crisis of faith (although I didn't handle any of them with much in the way of rationality, and it was luck as much as anything else that I was dumped out in the state of mind that I was in), and I have not since encountered anything that has led me to a crisis of faith. Given the huge amount I have learned since that last crisis of faith, I consider the odds of me having another one low.
There is one caveat I should mention, though: this whole issue may come down to a matter of perspective. To me, it's not a real crisis of faith unless you have to change your entire world view. Up until my last crisis of faith, I spent a lot of time thinking about how everything fit together in the universe. But then I had the realization, which came over me like a wave but soaked in to me very slowly, that all that really mattered was the evidence. So compared to that experience, nothing else has felt worthy of being called a crisis of faith.
That said, the method that Eliezer outlines seems to be a good one to follow. I have applied several of the techniques described with good success. So now that I think of it, maybe it is all just a matter of differences in what we really consider to be a crisis.
Since there's been much questioning of late over "What good is advanced rationality in the real world?", I'd like to remind everyone that it isn't all about post-doctoral-level reductionism.
In particular, as a technique that seems like it ought to be useful in the real world, I exhibit the highly advanced, difficult, multi-component Crisis of Faith aka Reacting To The Damn Evidence aka Actually Changing Your Mind.
Scanning through this post and the list of sub-posts at the bottom (EDIT: copied to below the fold) should certainly qualify it as "extreme rationality" or "advanced rationality" or "x-rationality" or "Bayescraft" or whatever you want to distinguish from "traditional rationality as passed down from Richard Feynman".
An actual sit-down-for-an-hour Crisis of Faith might be something you'd only use once or twice in every year or two, but on important occasions. And the components are often things that you could practice day in and day out, also to positive effect.
I think this is the strongest foot that I could put forward for "real-world" uses of my essays. (Anyone care to nominate an alternative?)
Below the fold, I copy and paste the list of components from the original post, so that we have them at hand:
