Not sure if this has been covered before. I use a well known survey site that allows mostly academic users to post studies for completion by a pool of registered users. I've been doing this for 2 or 3 years now for a bit of pin money. Increasingly I'm noting more and more confusion over what data these studies are collecting in terms of demographic info at the end of a study, and just don't understand what use the people constructing these studies think the information is going to be. For example, just now there was a study that asked me for the gender I identify as, and offered the options 'female', 'male' or 'other, n.a.'. It's a mess, isn't it? If there is a free text box I'll write something along the lines of gender being a social construct and that I am biologically female. But these are well-known academic institutions all over the world. Surely as part of a study being oked to go live, is a review of what data they are collecting, for what purpose and what they hope to achieve from each question? Very occasionally a study will ask for 'sex' and offer just female and male and then I find myself actually cheering out loud. Where is the academic rigour?
