“…The endowment effect demonstrates that people develop a sense of ownership just by being arbitrarily endowed with a good (e.g., coffee mug), even though they did not put any physical effort into obtaining the good (Kahneman, Knetsch, & Thaler, 1990;Schurr & Ritov, 2013). A related line of research shows that people judge the person who created an object to be its legitimate owner, even when the owner puts little effort into creating it (Levene, Starmans, & Friedman, 2015) or when others slightly alter the object (Kanngiesser, Gjersoe, & Hood, 2010). Taken together, it seems that even when the creation of a counterfactual requires little psychical effort, those who produce the counterfactual (i.e., rolled the die) will have a higher sense of ownership than those who just observed it.…”
