So far as I can tell, my resilience in this way is not an acquired defect but rather than an acquired sophistication.
When my working philosophic assumptions crashed in the past, I learned a number of ways to handle it. For one example, I've seen that when something surprises me, for the most part it all adds up to normality and crazy new ways of looking at the world it are generally not important in normal circumstances for daily human life. I still have to get dressed every morning and eat food like a mortal, but now I have a new tool to apply in special cases or leverage in contexts where I can control many parameters and apply more of an engineering mindset and get better outcomes. For a specific example, variations on egoism put me in a state of profound aporeia for about 3 months in high school, but eventually I worked out enough of a model of motivational psychology with enough moving parts that I could reconcile what I actually saw of people's pursuit of things they "wanted" and translate naive people's emission of words like "values" and "selfish" and "moral" and so on in ways that made sense, even if it sometimes demonstrated philosophic confusions similar to wish fulfillment fantasies.
It helps, perhaps, that my parents didn't force some crazy literalistic theism down my throat but rather tended to do things like tell me that I should keep an open mind and never stop asking "why?" the way most people do for some reason. Its not like I suddenly starting taking the verbal/theoretical content of my brain seriously in an act of parental defiance and accidentally took up adulterer stoning because that had been laying around in my head in an unexamined way. I was never encouraged to stone adulterers. I was raised on a farm in the redwoods by parents without college degrees and sent off to academia naively thinking it worked the way that it does in stories about Science And Progress. If I have such confusions remaining, my guess is that I take epistemology too seriously and imagine that other people might be helped by being better at it :-P
Eliezer's quoting of Feynman in the compartmentalization link seems naive to me, but it's a naivete that I shared when I was 19. His text there might have appealed to me then because it whispers to the the part of my soul that wants to just work on an interesting puzzle and get the right answer and apply it to the world and have a good life doing that. The same part of my soul and says that anything which might require compromises during a political competition for research resources isn't actually about a political competition for resources but is instead just other people "being dumb". Its nicer to think of yourself as having a scientific insight rather than an ignorance of the pragmatics of political economy. Science is fun and morally praiseworthy and a lot of people are interested in doing it. But where there's muck, there's brass so it is tricky to figure out a way to be entirely devoted to that and get paid at the same time.

I would like to ask for help on how to use expected utility maximization, in practice, to maximally achieve my goals.
As a real world example I would like to use the post 'Epistle to the New York Less Wrongians' by Eliezer Yudkowsky and his visit to New York.
How did Eliezer Yudkowsky compute that it would maximize his expected utility to visit New York?
It seems that the first thing he would have to do is to figure out what he really wants, his preferences1, right? The next step would be to formalize his preferences by describing it as a utility function and assign a certain number of utils2 to each member of the set, e.g. his own survival. This description would have to be precise enough to figure out what it would mean to maximize his utility function.
Now before he can continue he will first have to compute the expected utility of computing the expected utility of computing the expected utility of computing the expected utility3 ... and also compare it with alternative heuristics4.
He then has to figure out each and every possible action he might take, and study all of their logical implications, to learn about all possible world states he might achieve by those decisions, calculate the utility of each world state and the average utility of each action leading up to those various possible world states5.
To do so he has to figure out the probability of each world state. This further requires him to come up with a prior probability for each case and study all available data. For example, how likely it is to die in a plane crash, how long it would take to be cryonically suspended from where he is in case of a fatality, the crime rate and if aliens might abduct him (he might discount the last example, but then he would first have to figure out the right level of small probabilities that are considered too unlikely to be relevant for judgment and decision making).
I probably miss some technical details and got others wrong. But this shouldn't detract too much from my general request. Could you please explain how Less Wrong style rationality is to be applied practically? I would also be happy if you could point out some worked examples or suggest relevant literature. Thank you.
I also want to note that I am not the only one who doesn't know how to actually apply what is being discussed on Less Wrong in practice. From the comments:
I can't help but agree.
P.S. If you really want to know how I feel about Less Wrong then read the post 'Ontological Therapy' by user:muflax.
1. What are "preferences" and how do you figure out what long-term goals are stable enough under real world influence to allow you to make time-consistent decisions?
2. How is utility grounded and how can it be consistently assigned to reflect your true preferences without having to rely on your intuition, i.e. pull a number out of thin air? Also, will the definition of utility keep changing as we make more observations? And how do you account for that possibility?
3. Where and how do you draw the line?
4. How do you account for model uncertainty?
5. Any finite list of actions maximizes infinitely many different quantities. So, how does utility become well-defined?
