Decisions in the social preferences task (Study 1).

Decision #	Option A self, other		Option B self, other
1	$2,$2	(β ≥ 0) [86%]	$2,$1	(β ≤ 0) [14%]
2	$2,$2	(β ≥ 0.5) [23%]	$3,$1	(β ≤ 0.5) [77%]
3	$2,$2	(α ≥ 0) [42%]	$2,$4	(α ≤ 0) [58%]
4	$2,$2	(α ≥ 0.5) [31%]	$3,$5	(α ≤ 0.5) [69%]

For each option, we display the payoff for the decision-maker and the recipient, the associated model parameters (in parentheses) and the % of subjects choosing it (in square brackets). N = 150.
