Data on individual variations from one election to the next is fundamental in the study of political behaviour, and should, ideally, be collected through panel studies in which the same people are interviewed at two or more or elections. This method is, however, costly and time consuming, and most analyses of this type are therefore based on recall data, in which the voters report their choices in the current election and also in previous elections. The accuracy of recall data is discussed, based on data from the Norwegian Programme of Election Research in the period 1977–97. Analyses show that one must expect, using this type of data, that about one in four voters will give incorrect information about their voting behaviour at the previous election. Erroneous recall of previous voting can be explained by variations in the voters’ affiliation to the parties. Whereas stable voters who remain with the same party normally report their voting correctly, erroneous recall varies around 40 percent for party changers and rises to 70 percent among previous non‐voters. There is, however, no uniform underlying pattern in erroneous recall during different periods, which implies that it is difficult to predict exactly how erroneous recall will affect the accuracy of recall data in one particular election.
