*4.4. Recipient Behavior in the Ultimatum Game*

*Result 3: Reflective subjects are willing to accept lower offers in the ultimatum game than intuitive subjects. Reflective* subjects have on average a lower acceptance threshold relative to those not *reflective* (average threshold of DKK 27.8 and DKK 33.9, respectively). This difference is statistically significant at the 5% significance level (*p* = 0.032, MWU).

The average acceptance threshold was DKK 29.45. The modal acceptance threshold was DKK 10 and was chosen by 32.2% of the subjects whereas DKK 50 (requiring an equal split) was chosen by 29.7% of the subjects.

For the *reflective* subjects, the modal acceptance threshold was DKK 10, which was chosen by 36.6% in this category as opposed to 21.4% in the *intuitive* category. The modal acceptance threshold for the *intuitive* subjects was DKK 50, which was chosen by 37.5% in this category as opposed to 25% in the *reflective* category.

Both an acceptance threshold of DKK 0 or DKK 10 can be considered the rational, self-interested choice. 42.4% of the *reflective* subjects chose one of these thresholds as opposed to 29.7% of the *non-reflective* subjects. This difference is statistically significant at the 10% significance level (*p* = 0.074, *<sup>χ</sup>*<sup>2</sup> <sup>−</sup> *test*). When controlling for gender, *reflective* subjects are estimated to be 11.4%-points more likely, compared to *non-reflective* subjects, to choose an acceptance threshold of DKK 0 or DKK 10 as *recipient* in the *ultimatum game*. *Reflective* subjects are predicted to choose such an acceptance threshold with a probability of 42.2% as opposed to a predicted probability of 30.8% for those *non-reflective* (see Table 1).
