Dear Angry Professor,
Some time ago I requested the raw data for the studies that you published in [Social Science Journal]. I didn't get a response from you and I am now asking for the second time. If you have decided not to cooperate at least you could acknowledge my email.
Yours sincerely,
[Some Stranger]Well! First, I can appreciate this person's frustration, as I have myself attempted to obtain data from authors of other studies. It came as a surprise to me, naive thing that I was, that relatively few authors will actually comply with the agreement they signed in order to get their study published. I have only had success obtaining data from authors that I know personally. This is a problem that my professional organization, who publishes these journals, should probably deal with at some point.
However, imagine, if you will, someone asking for your data for a study you published, say, two years ago. Most of the software that folks in my discipline use to collect data generate output files in proprietary formats. Rendering "the raw data" in a useful format requires (based on my afternoon's activities) at least a few hours of digging through old files, rechecking and repairing machine and experimenter errors, and then generating text files somehow.
Having seen both sides of the "can I have your data" scenario, the very last thing I would do to get the cooperation of the person who must put in all this effort to send me the data is to fire off a rude email insinuating that the author was an unprofessional hack trying to hide something. I would first try to determine if my original request* had been received. But then again, this is probably a perfect example of how electronic messages can lead to misunderstandings and bad feelings.
*The original message, which was conveniently attached to this missive, also contained the remark: "Our goal is to verify, by reanalyzing your data, the substantive claims made in your paper." Gee, thanks. That makes me feel all warm and fuzzy.
