Here's something to pick our collective spirits up:
According to Google's infallible algorithms, 20% of the content on LessWrong.com falls within the 'Advanced' reading level. For comparison, another well-known bastion of intelligence on the internets, Hacker News, only has 4% of it's content in that category.
Strangely, inserting a space before the name of the site in the query tends to reduce the amount of content that falls in the highest bucket, but I am told that highly trained Google engineers are interrogating the bug in a dimly lit room as we speak, and expect it to crack soon.
If anything, it's weak evidence that the conversation is of poor quality. Doing the same search for TrueOrigin.org, a creationist site, for example, shows that it gets 70% 'advanced', 29% 'intermediate' and 0% basic.
'Advanced' reading level is almost always a pretty good proxy for obfuscation, rather than for intelligence.
Most reading level metrics are calculated with something like 206.835 - 1.015(total words/total sentences) - 84.6(total syllables/total words)*. Others involve long paragraphs and whatnot.
Besides being an amalgamation of funky constants to get answers the way they want (100 is easy, 0 is best for college-educated folks) it favors run-on sentences with polysyllabic words.
I think that most of the time, short well-phrased sentences are more understandable.
Long sentences of big words seem to be reminiscent of the incomprehensible journal article that takes ef... (read more)
