The Role of Explanations and Need for Uniqueness in Consumer Decision Making: Unconventional Choices Based on Reasons

This research investigates the interaction between a very common task, explaining decisions, and an individual difference, need for uniqueness (NFU), on buyer decision making. We propose that explaining (or providing reasons for) decisions shifts the focus from the choice of options to the choice of reasons. Furthermore, buyers who explain their decisions and have high NFU tend to select unconventional reasons and are, consequently, more likely to make unconventional choices.

The findings also indicate that the effects of providing reasons are not due to attempts to act rationally or to concerns about being evaluated. Three boundary conditions on the generalization that high NFU consumers who provide reasons tend to make unconventional choices we...
