NOTES
1 There was also a second control condition in which nobody crossed the street in front of the participant's car. The results for this condition closely resembled those for the control condition shown in Table 6.1.
2 Salience of political identity was manipulated in an experiment by Gaffie (2006), who found that identity as 'left' versus 'right' had a larger effect on attitude toward delinquents when it was made more salient by having the participant contrast these two orientations on a number of dimensions.
3 Difficult but not impossible. Appelbaum, et al. (2006) report an experiment on political attitudes in which several independent variables were manipulated across survey participants.
4 There was also a med-arb(diff) condition, in which a different person conducted the mediation and the arbitration. This condition was intermediate between the other two conditions on these measures.
5 Note that the laboratory experiment did a better job of pinpointing this mechanism than did the field experiment. As mentioned earlier, this is often the case.
6 The phrase comes from Morton Deutsch (private communication).
