Absence of zero plagiarism?
Have you ever seen statistics displaying zero plagiarism? Why is it absent?
The originality check software is able to produce statistics, such as zero plagiarism in relation to the number of submitted documents under the assumption that it receives feedback from higher education institutions on each submitted document with an opinion whether the work is plagiarised or not (software does not have the “last word” in plagiarism matters, but a man does). I have not seen such statistics yet – whether it is a faculty, a school or another level. It may be that such statistics will become standard in a few years (how many?).
