I think that this comic provides a fun introduction (after all, who doesn't love giant rampaging dinosaur discourse? Except maybe Randall Munroe, author of xkcd and professed raptorphobe ;)
My current two cents: My own personal experience leads me to suspect that it is true, and it's why you occasionally see random encodings (words describing a concept) popping up here; I'm trying to become more aware of ideas that I've never even considered--or at least not considered seriously--because I didn't have words for them. My worldview has been shifting a lot lately, and while I wouldn't say my actual vocabulary has expanded, I would say that my encodings have. In other words, I now have more concepts put in words (sometimes a lot of words in an ungainly conglomeration) that I never really even thought about before--in some cases, never realized they existed. Mainly, I suspect, because my existing worldview (collection of memes?) hadn't really allowed for them, and I didn't know words for them.
