We know it is normal to submit an abstract without having the result published yet. But what about an abstract where there was never a research from the author himself on the proposed topic? Regards
In my experience, this it is reasonably common in some engineering and computational science conferences which are organized as minisymposia, which have only presentations, and no peer-reviewed papers or proceedings, when the authors are most of the way to a result and expect to achieve it. The abstracts are often submitted describing the process to date with the results not mentioned or only mentioned including the results so far. I won't say that there has been no research done at all, but it's pretty common in my experience to see partial results submitted as though they were complete. Some of the results are presented having only been completed the night before the talk or the morning before an afternoon session. There are no lies in the abstract but only generic or vague phrases about the results in the abstract, and the attendees come expecting to hear about whatever results are achieved between submission/acceptance and the presentation. I've seen all of this happen in computational areas where running a simulation or computational experiment the night before is sufficient to get the result or negative result to put in the last slides of the talk the night before.
