Significance of successful modelling Successful prediction does not necessarily mean successful explanation, as we noted when discussing the 'sociometric' research of Chapter 2. We can still try to deny that statistical jiggery-pokery confirms the model. Unless subjects are doing a good job of post hoc confabulation and rationalisation, something else must be found to produce both the behaviour and the attitudes. In particular commentators have noted some problems of low behaviour-intention correlation. These do not seem bad.
Psychologists though do have a habit of burying an enormous amount of variation in error terms.
This problem will be taken up again below. David Regis, School of Education, University of Exeter, 1990.
