John Gerring has a new article in the British Journal of Political Science [ungated here]which attempts to restore description to its rightful place as a respectful occupation for political scientists. Description has indeed been relegated to the sidelines at the expense of causal inference during the last 50 years, and Gerring does a great job in explaining why this is wrong. But he also points out why description is inherently more difficult than causal analysis: ‘Descriptive inference, by contrast, is centred on a judgment about what is important, substantively speaking, and how to describe it. To describe something is to assert its ultimate value. Not surprisingly, judgments about matters of substantive rationality are usually more contested than judgments about matters of instrumental rationality, and this offers an important clue to the predicament of descriptive inference.’ (p.740) Required reading.
