Chemistry’s survey and matching process focus more on chemistry than compatibility. The survey has approximately 150 questions, with responses to questions designed to measure four personality types, each associated with a particular hormone or chemical: Explorer (Dopamine), Builder (Serotonin), Director (Testerone), and Negotiator (Estrogen). For example, users are asked in one question to indicate the length of their index finger relative to their ring finger (which can be related to the level of testosterone). In another question, users are read more asked to recognize sincere versus insincere faces, which Fisher argues is related to estrogen (being a Negotiator) (Gottlieb, 2006).

For example, in one recent interview she stated, «I think we are unconsciously attracted to those who complement ourselves biologically, as well as socially, psychologically, and intellectually. I think we fall in love with someone who has a different chemical profile for dopamine, serotonin, estrogen, and testerone that complements our own. This is the basic premise behind my work with Chemistry» XIII She has also stated that it is the prominent neurochemical within an individual that determines whether the preference is for similarity or complementarity.
