Regarding the investment, redheadedness was calculated using multiple procedures: participants’ care about-report about questionnaire, experimenters’ observer declaration inside lab data, and two ways of measuring hair coloration which have good spectrophotometer. A previously typed study on the results out of redheadedness towards the supplement D focus, that has been did on a single analysis, showed that every above-said evidence regarding redheadedness synchronised extremely strongly with each other and you can considering nearly identical efficiency (Flegr et al., 2020b). In today’s study, we have thus decided to employ merely mind-said redheadedness because this will give finest comparability with various prior (Freeze et al., Russian Brides sohbet odasД± 2017; Flegr and you can Sykorova, 2019) and coming studies in regards to the negative effects of redheadedness.

Correlations ranging from most other symptoms regarding redheadedness and you may sexual practices was shown inside the Supplementary Dining table S1, and you will again reveal that all of the ways of determining redheadedness give highly similar abilities. It signifies that the most basic and you will most affordable means, namely participants’ self-rating having fun with a primary ordinal level, can be well-known in future knowledge because encourages purchase of data away from highest people examples. Dimensions balances and methods off calculating most other indications off participants’ redheadedness, that are showed throughout the Supplementary Issue, try discussed from inside the Flegr ainsi que al. (2020b). Only toward reason for descriptive statistics, we have as well as calculated a binary varying from notice-reported redheadedness, where “non-redheaded” corresponds to responses step one, 2, and step 3 and you may “redheaded” represents responses 4, 5, and you can six.
Ages in the beginning sexual intercourse was calculated while the years at the such interest (limited away from lower than that have “12 much less” – code twelve and you will restricted away from over with “forty plus” – code forty; “We have maybe not had sex yet ,

Regarding the dataset out of Penke and you can Asendorpf (2008), product loadings into the “desire” grounds were > 0.
Sexual craft is actually projected because average amount of sexual intercourse 30 days in earlier times 12 months (seven classes: “0” – code step one, “1” – password dos, “2–3” – password step three, “4–6” – code 4, “7–10” – code 5, “11–20” – code six, “21–30” – code eight, “more than 30” – password 8). Non-heterosexuality is calculated from a couple details you to definitely inquired about brand new strength to be interested in individuals of an equivalent plus the opposite sex (anchored with “definitely not” – password 0, and you may “absolutely yes” – code 100; we meant to exclude people victims who would react that have “0” into each other scales however, zero such subject took part in the fresh new study). Non-heterosexuality are treated once the a binary adjustable having step one add up to are sexually interested in people of an equivalent sex to your exact same or maybe more intensity rather than folks of the exact opposite sex.
When you look at the heterosexuals, i reviewed what amount of sexual lovers of prominent sex as amount of sexual people of one’s opposite sex into the for the last seasons (nine groups: “0” – password step one, “1” – code 2, “2” – password step three, “3” – code 4, “4” – code 5, “5–6” – password 6, “7–9” – code seven, “10–19” – password 8, “20 or more” – code 9).
