Bureaucrats everywhere fall over themselves in their rush to replace judgements about quality and impact of research with simple statistics like citation scores and impact factors. It is plainly nonsense to think that such numbers provide evaluations that are better than informed judgements. Judgement cannot be displaced merely by counting things. The lunacy of citation statistics is clearly exposed in a report from the International Mathematical Union (IMU) in cooperation with the International Council of Industrial and Applied Mathematics (ICIAM) and the Institute of Mathematical Statistics (IMS). This is an interesting report for anyone who has an interest in impact factors and citation statistics.
