The Family Research Institute (FRI), originally known as the Institute for the Scientific Investigation of Sexuality (ISIS), is an American socially conservative non-profit organization based in Colorado Springs, Colorado which states that it has "...one overriding mission: to generate empirical research on issues that threaten the traditional family, particularly homosexuality, AIDS, sexual social policy, and drug abuse".

[2] The FRI is part of a sociopolitical movement of socially conservative Christian organizations which seek to influence the political debate in the United States.

They seek "...to restore a world where marriage is upheld and honored, where children are nurtured and protected, and where homosexuality is not taught and accepted, but instead is discouraged and rejected at every level.

[14] The opposition organization he formed was successful not only in defeating the proposed law, but in quickly becoming a major part of the nationwide anti-LGBT movement.

[12] In 1984, the Nebraska Psychological Association adopted a resolution stating that it "formally disassociates itself from the representations and interpretations of scientific literature offered by Dr. Paul Cameron in his writings and public statements on sexuality.

[22] The Southern Poverty Law Center has listed FRI as an anti-gay hate group[4] because of Cameron's discredited research[8][9] and claims about LGBT people.
