If we assume the grad students are in on it, it's because they'd want to move their careers forward. They're probably working in well established fields where returns for effort spent are diminishing. See the chart at http://cognitivesocialweb.com/home/2012/8/10/the-singularity-is-not-coming.html http://cognitivesocialweb.com/home/2012/8/10/the-singularity... So a combination of making no progress after years of effort, careerism or trying to stay in their field may motivate fraud. But I wouldn't be so sure about grad students who may handle smaller pieces of the whole project always being in on it. And either way, without fraud in these stupid difficult fields a lot more smartypants would be on Wall St., also committing fraud.
