I hope that my reply does not in any way discourage Richard Kennaway's reply. I am curious about different responses. But mine: rationalism intends to find better ways to satisfy values, but finds in the process that values are negated, or that it would be more rational to modify values.
Some time ago, I had grand hopes that as a human being embedded in reality, I could just look around and think about things and with some steady effort I might find a world view -- at least an epistemology -- that would bring everything together, or that I could be involved in a process of bringing things together. Kind of the way religion would do, if it was believable and not a bunch of nonsense. However, the continued application of thought and reason to life just seems to negate the value of life.
Intellectually, I'm in a place where life presents as meaningless. While I can't "go back" to religious thinking -- in fact, I suspect I was never actually there, I've only ever been looking for a comprehensive paradigm -- I think religions have the right idea; they are wise to the fact that intellectualism/objectivity is not the way to go when it comes to experiencing "cosmic meaning".
Many people never think about the double think that is required in religion. But I suspect many more people have thought about things both ways ... a lifetime is a long time, with space for lots of thoughts ... and found that "intellectualism" requires double think as well (compartmentalization) but in a way that is immensely less satisfying. In the latter, you intellectually know that "nothing matters" but that you are powerless to experience and apply this viscerally due to biology. Viscerally, you continue to seek comfort and avoid pain, while your intellect tells you there's no purpose to your movements.
A shorter way of saying all of this: Being rational is supposed to help humans pursue their values. But it's pretty obvious that having faith is something that humans value.
Although this comment is already long, it seems a concrete example is needed. Culturally, it appears that singularitarians value information (curiosity) and life (immortality). Suppose immortality was granted: we upload our brains to something replicable and durable so that we can persist forever without any concerns. What in the world would we be motivated to do? What would be the value of information? So what if the digits of pi strung endlessly ahead of me?

I think the "mental muscles" model I use is...
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
