Blind watchers of the sky
Over the past 20 years cosmology has made the transition to a precision science. Synergies between cosmology and particle physics will be pivotal in any future progress in the theoretical interpretation of the experimental evidence. To me however, this brings to mind what Feynman said: "The first principle is that you must not fool yourself and you are the easiest person to fool." This is further complicated by the fact that cosmology only makes observations not experiments, so virtually every inference is heavily model dependent. I will explore a couple of examples of how I think we can proceed as not to fool ourselves in the interpretation of forthcoming galaxy redshift surveys.
