But it's not necessarily true that if "verbose repetitive writing", has less information content than "taut clear prose". They could have the same information content, just the former has used more bits to describe the same information (i.e. is less compressed). I guess his question is why some people naturally produce the former and not the latter. Perhaps they just haven't performed the necessary computation required to compress the information while they were learning it, i.e. compression could either take place while they are storing the information in memory, or else during the editing process.
