Non-heterosexuality are computed away from a couple parameters one asked about the fresh new intensity to be drawn to folks of an equivalent together with contrary sex (anchored having “absolutely not” – password 0, and you will “absolutely sure” – code 100; i meant to prohibit one subjects who would act with “0” into the one another balances but zero such topic participated in brand new study).
