Abstract
This experiment provides evidence for this effect in a field setting. We approached residents of a specific city (referred to in what follows as “Smallville”) and offered them the opportunity to make two sequential decisions. Smallville is relatively small, with fewer than 30,000 inhabitants.
Materials
Experiment 4.sav Experimental design:
We have employed two expected visibility conditions (low vs. high) in a between-subjects design.
Sample:
n = 50 shoppers (34 women) in a local supermarket in the city of “Smallville.”
Participants were randomly assigned to two conditions, in a between-subjects design: high or low expected visibility of the consumed product.
Measurements
(First decision: Purchasing a product that reflects social identity)
A sign displayed at the entrance to the supermarket invited shoppers to purchase a product (a short-sleeved shirt). In both cases, the city logo was printed on the shirt, reflecting participants’ social identity.
(Low-expected visibility condition)
The sign invited shoppers to buy a pajama top – reflecting low-expected visibility of the consumed product.
(High-expected visibility condition)
The sign invited shoppers to buy a t-shirt – reflecting high expected visibility of the consumed product.
(Second decision: Choosing a free gift)
A shopper who purchased a t-shirt was invited to choose a free pen. Two types of pens were offered: one expressing shoppers’ social identity (a pen printed with the city logo), and the other expressing their personal identity (a pen in a color of the shopper’s choice).
We coded a shopper’s second choice as “consistent” if he or she selected a pen printed with the city logo.
Hypotheses
H1: In a set of sequential identity-related product decisions, an individual is more likely to engage in consistent behavior—i.e., to make a second decision that emphasizes the same (personal or social) identity as the first decision—when the product involved in the first decision is expected to be consumed in high-visibility rather than low-visibility circumstances.
