More and more academic institutions are using citation analysis as the main technique for measuring the quality of scientific research.
Conclusion
Citation analysis works against the goal of encouraging good research.
rephrase: by doing citation analysis, you're not encouraging good research. (Maybe you're encouraging bad research!)
Evidence (since)
Citation analysis counts references to a researcher's work in journals.
Scientists trying to maximize citation counts will avoid multiyear projects in favor of short-term, faddish ones.
Evaluate
The conclusion is essentially saying that "citation analysis | leads to less-good research".
What does the evidence say about citation analysis?
It's basically saying that we scan scientific journals once a year to count the number of times that a certain researcher's work gets mentioned. Implicitly, the more times your work is being mentioned, the higher quality we think your work is.
What does the evidence say about leading to less-good research?
Nothing. What he year is that citation analysis will lead to avoiding multiyear projects and instead doing short-term projects in faddish areas.
So the author is assuming that we are getting "less-good research".
Should our common sense accept that assumption? Probably. So maybe the answer will test it, or maybe they just expect us to play along with the common sense notion that short / trendy studies are not as robust or meaningful as serious / long studies.
The author is also assuming that scientists who work on short-term fad projects will get more yearly mentions than scientists who work on long-term projects. Is that an assumption our common sense should accept?
Hmm, probably not. After all, scientific journals might have standards where they don't publish any articles about these quick / inferior / trendy studies, or there's a professional taboo against citing lower-brand science like this.
Maybe the longer projects are so good that they are cited for years and years, so even though you're busy working on your next long project, you're still being cited for your last long project that ended several years ago.
Goal
Let's look for an answer helping to convince us that we get less good research when scientists switch away from multiyear projects and into short-term faddish projects, or one that helps convince us that scientists working on short-term projects would get more yearly citations than those working on long-term projects.
