Previously, I complained that David Hemenway (Harvard) and co-authors would not give out the data to a recent study that they did on road rage despite the fact that they had already published a paper in a journal and gone public talking to the media. Recently, however, I have asked for data from two other surveys in 1996 and 1999 that Hemenway also conducted. The 1996 data is available at the ICPSR, but the data from the 1999 survey is not released and Hemenway is not responding to requests on information on even when the data will be released (I last asked on March 9th). It seems as though seven years, long after their study results have been published, is excessively long. The strategy that Hemenway seems to be following is to delay providing the data for so long that no one is able to critically comment on his research simply because the data is so old. An possible concerns that anyone might have would be easy to resolve if data were provided in a timely manner.
