Self-Personalisation vs Other-Personalisation

Research has identified self-control limitations as a significant barrier to making sustainable food choices. Even individuals motivated to consume sustainably may indulge in unsustainable food options when they are particularly attractive. The project compares two strategies to address these self-control limitations: self-personalisation and other-personalisation.

In self-personalisation, individuals can opt-in to a default setting that hides unsustainable food options when choosing a meal in an online experiment. In contrast, other-personalisation involves others opting individuals into hiding unsustainable food options during the same online meal choice. This experimental design allows us to compare the environmental impact and decision-making outcomes, such as experienced autonomy and satisfaction, of both personalisation procedures. The findings aim to enhance understanding of who should be responsible for personalisation.
