I got to listen to this yesterday when I was out and about. I understand what's being said about subjectivity and inescapable biases, but to me this makes a stronger case for objectivity than subjectivity. Objectivity is more than basing decisions strictly on measurements. It's also about removing as many of those biases as possible (including knowing how something measures) and making decisions based on what you hear.
I do agree that it's unfair to just dismiss something based on measured performance alone, and it does seem like a lot of self proclaimed objectivists look at the measurements and "listen with their eyes". That to me however, is not being objective. I think part of being objective is not only to be aware of your biases, but to also understand that you cannot escape them. Take every experience with a grain of salt. Just knowing about biases isn't enough. You have to understand that you can't control or escape them, and to me that's part of being a good objectivist.
