And models, too

I will also want to make a list of relevant theoretical options and considerations. For example, "A Theory of Dark Matter" has been a popular paper, describing a nontrivial, nontraditional dark sector. It might be an interesting exercise to second-guess Nima Arkani-Hamed, by combining "simply unnatural supersymmetry" with "dark matter with Sommerfeld enhancement" (two ideas to which he contributed), and then trying to fit all the data.
