The IDRlabs Cats or Dogs Test utilized research from psychologists Samuel Gosling, Carson Sandy, and Jeff Potter to produce this free online test. This test also employs the Big Five Inventory (Oliver John, Laura Naumann, Christopher Soto, 2008), with its scales of openness, conscientiousness, extraversion, agreeableness, and neuroticism, in order to determine the likelihood of one’s being either a cat person or a dog person. IDRlabs International and the present IDRlabs Cats or Dogs Test are independent of the above-stated researchers and their respective academic institutions.
