Some old dated worldviews have been critisised for their lack of technical accuracy. However I have seen tendency to take technical statements and turn them into worldviews. I am suspecting that this is not a valid operation and it is used to hide cultural imports. That are fo the form "A->B" where A is heavily supported by evidence but the implication is very suspect. Statements like "if the moon is made of rocks, then the moon is a evil place. We have moon rock samples so clearly the moon is evil". These are tricky in the sense that while it is clear what is meant by moon being rocky the actual payload is made of terms that are not (at least handily or unambigiously) turnable into technical details. This kind of gist that seems to be a different thing from technical accuracy seems to be often dismissed as giberrish or nonsense by those that want to focus on facts (thus it becomes true->false which is a true implication). However seems to be that even if all your thoughts would be "literally" or techincally accurate there would still be something essential missing from full sanity. What it could be and if any "canditates" for it are known to be defective or adeqaute approximations would be interesting to read about.
As many people have noted, Less Wrong currently isn't receiving as much content as we would like. One way to think about expanding the content is to think about which areas of study deserve more articles written on them.
For example, I expect that sociology has a lot to say about many of our cultural assumptions. It is quite possible that 95% of it is either obvious or junk, but almost all fields have that 5% within them that could be valuable. Another area of study that might be interesting to consider is anthropology. Again this is a field that allows us to step outside of our cultural assumptions.
I don't know anything about media studies, but I imagine that they have some worthwhile things to say about how we the information that we hear is distorted.
What other fields would you like to see some discussion of on Less Wrong?
