They suggests that the most basic and you will most affordable strategy, particularly participants’ thinking-rating having fun with a preliminary ordinal scale, shall be well-known in future knowledge whilst facilitates purchase of investigation of high population examples. Aspect scales and methods from figuring other symptoms of participants’ redheadedness, which happen to be exhibited in the Additional Question, is explained in Flegr mais aussi al. (2020b).

Non-heterosexuality are computed off a couple of parameters you to definitely asked about the new strength to be keen on folks of the same and the reverse sex (anchored having “absolutely not” – code 0, and you may “absolutely yes” – code 100; we designed to prohibit one sufferers who would work with “0” to the each other scales but zero for example subject participated in brand new study). Non-heterosexuality are addressed because a binary variable having step 1 equal to being sexually keen on people of a similar sex to your exact same or even more strength than to individuals of the exact opposite sex.
In heterosexuals, i reviewed how many sexual couples of your prominent sex while the number of sexual couples of your own contrary sex within the during the last seasons (nine kinds: “0” – password step one, “1” – code 2, “2” – password step 3, “3” – code cuatro, “4” – password 5, “5–6” – password six, “7–9” – password 7, “10–19” – code 8, “20 or higher” – password nine).
