Hopefully many of you will have read this paper already. It's probably the most highly cited (and publicly discussed) paper to come out of communication over the last few years: | |||

Although there are major ethical concerns with the paper, and we'll be coming back and talking about it a number of times this quarter, let's focus on the key issues of research design and the substantive takeaway. | |||
For this paper, answer each of these questions and be ready to cite parts of the paper that support each claim: | |||
