Table 1.

Number of SNPs in each gene that did and did not exhibit at least one association with a variable within each behavioral domain

	Disposition		Dyadic relationships		Wider network
Receptor gene	Any significant	None significant	Any significant	None significant	Any significant	None significant
Testosterone	1	3	0	2	0	2
β-Endorphin	6	14	2	8	1	9
Vasopressin	1	7	0	4	0	4
Oxytocin	2	38	9	11	2	18
Dopamine	1	15	1	7	3	5
Serotonin	0	8	0	4	1	3

The above counts for oxytocin (disposition) and dopamine (disposition, dyadic relationships, and wider network), based on Pearce et al.’s table S2, and cross-checked with statistics reported in text, do not match the proportions reported in Pearce et al.’s figure 2. The proportions reported in Pearce et al. for these cells appear incorrect.
