Learning the basic high-school version of essay writing prepares one to write non-technical research papers.
A research paper tends to be structured essentially like an exaggerated essay. Reason and thesis up front, body supporting thesis, and conclusion.
In research papers, that's the same format. It's also a loose format, reason for paper doesn't need to be first paragraph, same with thesis, but in essence, the structure is the same.
Any analytical career is going to use research papers. Businesses will use research documentation for the higher level business efforts. Rarely will a big presentation that deals with the same information ever be only a presentation. You'll have written documentation, or that written research paper will be a proposal to continue said efforts, with the presentation being the finale.
Sure, most people won't ever use it - but as was said earlier in the thread, it prepares the individual for analytical thinking, organization, and the flow of thoughts.
I fail to see how you cannot see any of these connections. Just because you may not be in a career track that makes use of these at the lower levels, most major business decisions, regardless if its related to marketing in any way, if it's a significant change to their normal efforts the business uses, will likely involve someone writing a research paper.
But in general, it'll less likely be a business thing, and rather an analytical position. Anybody that ends up in an analytical position anywhere will likely be dealing with this. The final proposal or research paper may not resemble an essay to the naked eye, but the process is all there. Propose an argument, back up the argument, and make a conclusion as to why your argument is absolutely correct as per the demands of the reason of the document.
