 I was one of the facilitators to talk through one of the groups during lunch, so the idea was we would have a working lunch and engage with the specific groups. Each group was paired with one or two people who were experts in the field or had a particular interest in it, so I was paired with the big data team. The people who are looking at edX and different initiatives around MOOCs with Harvard and I do a lot of work around data and privacy. So the idea was to brainstorm, give them feedback on what they've done, talk about their presentations and maybe inspire them a little bit with real life examples of what we've done, help them along, identify questions they may want to look at, different areas of research or help fine tune what they're already doing and I guess really just to have a dialogue about their work. So I think one of the issues was around consent, so we were talking about people having their data that is held by an educational institution be shared for research purposes and the assumption was well of course if you ask people they'll say yes I'm very happy for my data to be used, nobody would say no and I sort of immediately jumped up and said well I would say no which sort of seemed to come as a surprise to the person working on the project, she's like why would you say no, you know kind of this immediate assumption that all data, all research is for a good purpose so why would you not want it to be shared and I was talking about a developing country perspective which is what I'm more familiar with and how often the consent that you give isn't fully informed consent, there are issues around people not having the education, the literacy, the knowledge of what might be done with their data to be able to even make informed choices so sort of adding that slightly different perspective around how if you start a program or if you design an interface working off an assumption that yes of course people are happy to share why wouldn't they, it already sort of designs a certain path you're going to go down and it's not flexible enough and maybe looking at the sort of devil's advocate side of the spectrum and saying well why would people not want to give their data and then allowing people genuine choice and having that consent be meaningful is something you do need to think about so that was something that sort of came up which I think they hadn't quite thought about.
