in defense of subjectivity [sound the gong]

When browsing the IMS Bulletin [01 October] a few days ago, I saw that Ruobin Gong (from Rutgers) had written a tribune about Subjectivism. In response to [IMS President] Krysz Burdzy’s presidential address at the IMS Meeting in London a few months earlier. Address that I had missed and where he was calling for the end of the term subjective in statistics… (While ironically attending the Bayesian conference in Montréal!) Given the tone of his Search for Certainty book, which Andrew and Larry and I discussed a while ago, I am not at all surprised by another go at Bayesian statistics, but I will not indulge into another response, since Krysz found my earlier review “venomous”! Especially since Ruobin has produced a deeply argument ed and academically grounded criticism of the presidential address (which, if I may mention it, sounds rather rambling away from statistics). In particular, Ruobin introduces Objectivity³ as “an interpreted characterization of the scientific object”, which reminds me of Nietzsche’s aphorism about physics. And where personal and collegial inputs are plusses, even though they could be qualified to be “subjective”. This was also Poincaré’s argument for Bayesian reasoning. In conclusion, I think that the London call to cease using the term in statistics was neither timely (as the subjective-versus-objective debate has sort of dried out) nor appropriate (in that it clashed with the views of part of the IMS community).
