Abstract

Whereas the literature on choice overload has shown that people tend to defer their choice or experience less satisfaction under choice proliferation, this paper aims to test how the profusion of choice directly affects individuals’ revealed preferences over options. To do so, we run an experiment where subjects have to compare familiar (i.e., easy, salient and relatively safe) and unfamiliar options under different choice contexts (Large or Small choice sets). We hypothesize that, as the choice set expands, the decisions become harder and more costly and subjects may find familiar items relatively more attractive. Our results provide clear evidence of set size dependence of revealed preferences: Subjects prefer familiar items more frequently in larger choice sets. This evidence is robust to a number of experimental variations and statistical controls.

Notes

  1. Neither of these two phenomena is unambiguously established (see the meta-analyses in Scheibehenne et al. (2010) and Chernev et al. (2015), who come to rather opposite conclusions).

  2. Such an option may also represent a satisficing option à la Simon (1979), i.e., gives a sufficient level of satisfaction to choose it over an unfamiliar option, which would require more effort for a more uncertain outcome.

  3. In the experiment reported by Dean et al. (2017), the subjects are forced to choose an option. In line with their own interpretation of the results, retaining the default/status-quo option may be seen as a way of avoiding choice, rather than a deep change in one’s preferences.

  4. We assume there exists a minimal effort: e.g., read the name of option. We also assume that the representation of the option cannot be sure to make it possible uncertainty that is not due to information or knowledge about the options but to variations in the internal state of the decision-maker, variation in the context of consumption, etc.

  5. This property is easily generalized by considering the case where a and b belong to \({\widetilde{C}} \cap {\widehat{C}}\), where the former set is neither a subset nor a superset of the latter. However, we think that the text version is more intuitive, given our experimental design where subjects face one of two choice sets, one being a subset of the other.

  6. It is clear that the definition of rational preferences, which correspond “set size independence”, implies such a property but the contrary does not hold.

  7. A difference between the Dean et al. ’s (2017) model and our framework is the fact that they assume that the status quo is an option while it is a set of options in our context.

  8. A somewhat similar axiom, the Deferral Monotonicity axiom, is introduced by Gerasimou (2018). It states that a decision-maker chooses to defer her choice in a set C if she does it when facing a smaller set \({\widetilde{C}} \supset C\).

  9. It would be possible that enlarging a choice set makes more likely the preference reversals among a type of items. For instance, a decision-maker might prefer \(n_1\) over \(n_2\) when facing \(\{n_1,n_2\}\) but \(n_2\) over \(n_1\) when facing a larger set because more alternatives might entail higher decision costs or regret. As we do not consider this type of set dependence, our measure of choice set dependence might be underestimated.

  10. We do not present some theoretical mechanisms that although intuitively promising, actually fail to explain the growing attraction of familiarity with the set size: namely, errors, symmetric regret or incomplete preferences.

  11. The idea that individuals may feel regret and, therefore, violates the ‘standard’ theory of rational choice has been introduced by Loomes and Sugden (1982) or Sugden (1993).

  12. There is now an extensive body of literature on limited attention, consideration sets and their formation in consumer research, marketing and psychology (Hauser & Wernerfelt, 1990; Mehta & Srinivasan, 2003; Roberts & Lattin, 1991), and in theoretical and empirical economics as well (Dean et al., 2017; Geng & Özbay, 2020; Goeree, 2008; Masatlioglu & Nakajima, 2013; Masatlioglu et al., 2012).

  13. Note that it might be replaced by another unfamiliar item.

  14. These websites offer their own content, which excludes e-commerce websites and social networks.

  15. We checked this in the post-experiment socio-demographic questionnaire: our subjects spend an average of 1 hour 49 minutes on the web per day.

  16. The instructions (translated from the French) can be found in Appendix 1.

  17. The comments were drafted as follows: “I recommend this website/I do not recommend this website” plus an explanation. To control for the nature of the recommendations, 50% of the websites in a category had positive comments and 50% negative comments. Moreover, the positive and negative recommendations for a given website were reversed across sessions to produce a balanced design.

  18. See Lusk et al. (2008) for an evaluation of such a methodology.

  19. To a certain extent, our design, based on a real-consumption incentive mechanism, is simpler than what could be obtained with a monetary incentive scheme to study preferences for options within a choice set. Indeed, the latter would require us to introduce either a budget set, which can be a more demanding cognitive task, or payments in multiple dimensions (risk or uncertainty, time). Moreover, using everyday life consumption goods available for free (like content websites, music on the internet, etc.) is suitable for placing subjects in a simple and usual choice condition. To the best of our knowledge, no systematic experimental study has compared the relative performance of monetary and non-monetary incentive mechanisms.

  20. The average number of “likes” of the most popular websites in a choice set is around 346,000 (\(C^+\)) and 313,000 (\(C^-\)), with a certain heterogeneity from 117,000 (Economics and business) to 700,000 (General news). The least popular website has around 3,000 (\(C^+\)) and 5,000 (\(C^-\)) “likes”.

  21. One might argue that it should be better to use the reputation of websites (“Blockbuster”/middle/niche) rather than their familiarity. However, even if by construction a familiar item could be a “Blockbuster”, we argue that reputation is a less convincing criterion for evaluating choice overload. First, a “Blockbuster” website might be salient, but it is less likely to be easy and safe. If an individual heard about such a website but is not used to consult it, it can be difficult to form a precise belief about the satisfaction she might obtain from its consumption without having to exert much cognitive effort. Second, reputation is not a clear signal of quality. A “Blockbuster” or “superstar” item may not always provide much greater satisfaction than a less famous item (Rosen, 1981). Third, the choice of a “Blockbuster” item could come from social considerations outside of the lab, such as social norms or peer effects, that are hard to control.

  22. In the treatment where subjects face a small set without any information, a familiar item has 88.6% probability of being preferred to an unfamiliar one. It can be seen as supporting our experimental conjecture that familiar items give a sufficient and safe level of satisfaction when effort level is minimal, as it also rules out other motivations for choice, e.g., curiosity.

  23. The full distribution of individual frequencies with which familiar items are preferred to unfamiliar ones can also be represented by the empirical cumulative distribution functions. This is shown in Fig. 5, in Appendix 1. The conclusions drawn from the pooled frequencies seem to be valid at the individual level, where for all levels of information the distributions of the individual frequencies in which a familiar is preferred to an unfamiliar option in \(C^-\) (almost fully) dominate the distributions for (unrestricted) \(C^+\).

  24. For instance, for \(I^-\) in the unrestricted case, we use \(\mathrm {Prob}(f \succ _{C^+} n | n \succ _{C^-} f) = \mathrm {Prob}(f \succ _{C^+} n \cap n \succ _{C^-} f) / \mathrm {Prob}(n \succ _{C^-} f )\). Here, \(\mathrm {Prob}(f \succ _{C^+} n \cap n \succ _{C^-} f)\) is supposed to be equal to 0.349-0.284 = 0.075, i.e., we assume that \(n \succ _{C^+} f\) implies \(n \succ _{C^-} f\) (as implied by the Contraction axiom). Then: \(\mathrm {Prob}(f \succ _{C^+} n | n \succ _{C^-} f) = 0.075 / 0.349 = 0.2148\).

  25. This perceived complexity may come from having too many mental elements to weigh at the same time, and may yield an asymmetric effect in terms of subjective beliefs about individual options.
