On the distinction between yuppies and hippies: Individual differences in prediction biases for planning future tasks

The present study investigated variables related to errors in predicting when tasks will be completed. Participants (N = 184) responded to the Time Structure Questionnaire (TSQ; Jones, Banicky, Pomare, & Lasane, 1999) and Temporal Orientation Scale (TOS; Bond & Feather, 1988) and predicted when they would complete either a desirable or undesirable task. Factor analysis of the TSQ and TOS identified two factors: yuppie traits, which involved being hard-working and goal-oriented, and hippie traits that reflected ‘‘living for the moment’’. Overall, individuals tended to underestimate when they would complete both tasks. However, for the undesirable task, yuppie traits corresponded with less prediction bias whereas hippie traits were associated with greater bias. 2006 Elsevier Ltd. All rights reserved.
