Science-based dating sitesThis is a featured page

In algorithmic pair matching, science-based dating sites are those pair-matching websites that claim to use “science”, such as chemistry, genetics, psychology, thermodynamics, or the scientific method, etc., to match up potential couples. [1]

History
One of the first sites to implement a scientific methodology to the algorithmic matching of individuals was eHarmony, who in 1997, under the guidance of American psychologist Neil Warren, began to use the findings of relationship research psychology to devise matching algorithms that could be implemented in an online matching framework. [2]

In 2003, American chemical engineer Glenn Gasner began to study correlations between personality types of people in long term marriages, using the scientific method, and in doing so launched the personality testing site PersonalityExpert.com (later Perex.com). After gather data on over 200,000 individuals, and filtering the data into various psychological typings (Five Factor Model, Keirsey Temperament Sorter, Myers-Briggs Type Indicator, etc.), Gasner launched eChemistry, a type matching site designed to match for "chemistry".

One of the more ironic sites in the science-matching category is Chemistry.com, a subsidiary of Match, launched in 2006, which claims to match people according to “chemistry” according the matching theories of American anthropologist Helen Fisher. [3] The irony here is that an “anthropologist” supposedly knows more about the subject of chemistry between people, i.e. human chemistry, romantic chemistry, social chemistry, physical chemistry, sexual chemistry, interpersonal chemistry, neurochemistry, etc., than any other researcher in the world?

In 2007, American chemical engineer Eric Holzle launched ScientificMatch, which was one of the first sites to have users send in physical body samples to facilitate matching. In particular, using the 1995 findings of the famous “sweaty T-shirt study”, which showed that people are most sexually attracted to the smell of a mate that has the most dissimilar major histocompatibility complex (MHC), Holzle charges $2,000 dollars to match people via MHC-compatibilities, by having them send in saliva samples.
