Yes, to some extent. There is a fair amount of academic research written particularly about perceptions of biotechnology. The one well studied example is perceptions of biotechnology. THere are pretty good explanations on why most of Europe is much more opposed to biotechnology than the United States.
Anyway, I would ramble on, but I'm only helping interpret google search results if I talk any more.
However, try googling (especially using google scholar) terms such as:
agricultural perceptions
agriculture philosophy
agriculture sociology
agriculture psychology
and just for fun, Food for Thought actually gets some stuff too
As for the actual reasoning: besides what ERIC said (public disconnect with agriculture), agricultural research is not necessarily a simple thing to do. The nature of agriculture means that it requires large scale studies over several years, and narrow comparisons in studies are often not reflective of the much more complex systems that require a broader view. The result is that it is often not difficult to design, produce, or find an experiment, and the "evidence" that comes with it, that suits somebody's beliefs.
