What should I do if I think a researcher in my university is intentionally employing incompetent people? In our university there are a lot of great researchers and a very competent people in general. I've discovered today that one of our researchers is intentionally employing people who are totally incompetent. I think that he's doing this to appear as a great teacher and supervisor, because, as far as I know, he was a supervisor for all of them in the past.

I personally know some of these incompetent researchers, since their first year of undergraduate studies. They were those people who find it incredibly hard to pass every course, especially maths.  I've been giving one of them remedial lessons to make him able to pass a database course. He finally made it on the 3rd attempt. His other courses weren't much better - he failed literally EVERY maths course until the last possible attempt.

Today, I discovered that he and several people similar to him are employed as researchers.  Some of them were there even before completing their B.S (which is usually not allowed even for the most talented students).

What should I do to notify others of this situation and without worsening my position in my colleagues' eyes?

The researcher is a man of a great reputation (or at least, much greater than I am as a postgraduate :-) ), so I'm afraid of being just considered malicious and jealous man. On the other hand I'm pretty angry about all this, because there are some very expensive international projects, where money for these people are completely wasted and a research progress is much slower than it has to be. Those positions could be occupied by really talented and competent people and not just by somebody, who was supervised by one specific man.
My suggestion is that you let it go for three reasons:


This is hardly the last time you'll come across this problem, inside or outside of academia.
There are factors here you might not be considering or know nothing about.  Maybe the person you're tutoring in math has excellent people skills, or is the instructor's nephew, or the Dean's. Whatever the reasons they're really not any of your business.
As you say, you will indeed end up being considered a malicious and jealous man.  


If it really bothers you you should probably find somewhere else to work where this isn't a problem, but then see point #1, above.
