| Abstract: | Recommendations, for example, by "the chef" help increase healthier and/or more sustainable food choices. However, little is known about whether recommendations are still effective when choices are limited, as is typically the case in university cafés. More importantly, it is unclear how factors such as price interact with the recommended choice or menu. To test this, participants (N = 512) in a smartphone-based online study were visually presented with two menus (Dahl or Curry) from which they had to choose one, with either none recommended or one of two (none, Dahl or Curry). Additionally, we manipulated the price of the menus (high or low) and the position of the menus (top or bottom). Participants were then randomly assigned to one of the resulting 12 factor-level combinations (for example, the recommended expensive Curry menu at the top, the cheap Dahl menu at the bottom). The subsequent analysis (probit with post-hoc ANOVA) with recommendation, price and position as independent variables and menu choice as dependent variable showed more or less only effects regarding the choice of the more popular menu, the Curry (chosen on average with 66%). Specifically, only when the Curry menu was presented at the top did a differential effect of recommendation emerge. That is, when the Curry was the expensive option, the recommendation had a negative effect on its choice (43% chose it), but not when the Curry was the cheap option (87%). To conclude, only if, for example, university cafés know whether a menu is popular might manipulations such as position or recommendation be useful in further promoting a particular menu choice. |
