Dimensions scales and methods from calculating other symptoms out-of participants’ redheadedness, which happen to be demonstrated from the Second Material, are demonstrated during the Flegr ainsi que al. (2020b). Entirely on the purposes of descriptive statistics, i have along with computed a digital varying out-of mind-advertised redheadedness, where “non-redheaded” represents responses step 1, dos, and you can step three and you will “redheaded” corresponds to responses cuatro, 5, and you will six.

On dataset away from Penke and you will Asendorpf (2008), goods loadings to the “desire” basis was in fact > 0.

Sexual interest are estimated as average number of sexual intercourse per month prior to now 12 months (7 categories: “0” – password 1, “1” – password dos, “2–3” – password step 3, “4–6” – password 4, “7–10” – password 5, “11–20” – password six, “21–30” – password seven, “more than 30” – code 8). Non-heterosexuality is actually determined out of a couple of variables one asked about the fresh new power of being attracted to people of an identical and contrary sex (anchored with “definitely not” – code 0, and you may “positively yes” – password 100; i intended to ban any subjects that would work which have “0” on the each other balances however, no including topic took part in the fresh study). Non-heterosexuality try managed due to the fact a binary variable that have 1 equal to becoming sexually interested in folks Evlilik iГ§in SД±rpГ§a kadД±n of the same sex towards exact same or higher power than to individuals of the alternative sex.

Inside heterosexuals, we reviewed the amount of sexual partners of the prominent sex as the level of sexual partners of the contrary sex into the for the last season (9 categories: “0” – code 1, “1” – password dos, “2” – password step three, “3” – password cuatro, “4” – code 5, “5–6” – code six, “7–9” – code seven, “10–19” – password 8, “20 or maybe more” – code nine).
