You'll notice the ratings are fairly close, and the study notes that, too; the only statistically significant field was "pleasant to read," where the journalist article won handily. (Take that, machines.) But the fact that the results weren't significant is, in itself, possibly significant; the people surveyed didn't seem to care which article they read. This was backed up when Clerwall had the participants guess which article was written by a person, and which by a machine. "Of the 27 respondents who read the software-generated text, 10 thought a journalist wrote it and 17 thought it was software-generated. For the 18 respondents in the 'journalist group,' 8 perceived it as having been written by a journalist, but 10 thought software wrote it," he writes in the study.
