Non-heterosexuality was calculated out-of several details one asked about this new power to be interested in people of an identical together with opposite sex (secured with “absolutely not” – code 0, and “positively yes” – password 100; i designed to ban people victims that would react with “0” on each other balances however, no particularly topic participated in new study).
