Influences On Sexual Orientation: Professional Organizations' Statements
Further information: Theories on homosexualityA legal brief dated September 26, 2007, and presented on behalf of the American Psychological Association, California Psychological Association, American Psychiatric Association, National Association of Social Workers, and National Association of Social Workers, California Chapter, stated:
Currently, there is no scientific consensus about the specific factors that cause an individual to become heterosexual, homosexual, or bisexual — including possible biological, psychological, or social effects of the parents' sexual orientation.And added in a footnote:
Although much research has examined the possible genetic, hormonal, developmental, social, and cultural influences on sexual orientation, no findings have emerged that permit scientists to conclude that sexual orientation – heterosexuality, homosexuality, or bisexuality – is determined by any particular factor or factors. The evaluation of amici is that, although some of this research may be promising in facilitating greater understanding of the development of sexual orientation, it does not permit a conclusion based in sound science at the present time as to the cause or causes of sexual orientation, whether homosexual, bisexual, or heterosexual.The American Psychological Association, the American Psychiatric Association, and the National Association of Social Workers in 2006 stated:
Currently, there is no scientific consensus about the specific factors that cause an individual to become heterosexual, homosexual, or bisexual – including possible biological, psychological, or social effects of the parents' sexual orientation. However, the available evidence indicates that the vast majority of lesbian and gay adults were raised by heterosexual parents and the vast majority of children raised by lesbian and gay parents eventually grow up to be heterosexual.The American Academy of Pediatrics in 2004 stated:
The mechanisms for the development of a particular sexual orientation remain unclear, but the current literature and most scholars in the field state that one's sexual orientation is not a choice; that is, individuals do not choose to be homosexual or heterosexual. A variety of theories about the influences on sexual orientation have been proposed. Sexual orientation probably is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences. In recent decades, biologically based theories have been favored by experts. Although there continues to be controversy and uncertainty as to the genesis of the variety of human sexual orientations, there is no scientific evidence that abnormal parenting, sexual abuse, or other adverse life events influence sexual orientation. Current knowledge suggests that sexual orientation is usually established during early childhood.The Royal College of Psychiatrists in 2007 stated:
Despite almost a century of psychoanalytic and psychological speculation, there is no substantive evidence to support the suggestion that the nature of parenting or early childhood experiences play any role in the formation of a person's fundamental heterosexual or homosexual orientation. It would appear that sexual orientation is biological in nature, determined by a complex interplay of genetic factors and the early uterine environment. Sexual orientation is therefore not a choice, though sexual behaviour clearly is.The American Psychiatric Association stated:
No one knows what causes heterosexuality, homosexuality, or bisexuality. Homosexuality was once thought to be the result of troubled family dynamics or faulty psychological development. Those assumptions are now understood to have been based on misinformation and prejudice.Read more about this topic: Sexual Orientation
Famous quotes containing the words influences on, influences, professional and/or statements:
“Professors of literature, who for the most part are genteel but mediocre men, can make but a poor defense of their profession, and the professors of science, who are frequently men of great intelligence but of limited interests and education, feel a politely disguised contempt for it; and thus the study of one of the most pervasive and powerful influences on human life is traduced and neglected.”
—Yvor Winters (1900–1968)
“However diligent she may be, however dedicated, no mother can escape the larger influences of culture, biology, fate . . . until we can actually live in a society where mothers and children genuinely matter, ours is an essentially powerless responsibility. Mothers carry out most of the work orders, but most of the rules governing our lives are shaped by outside influences.”
—Mary Kay Blakely (20th century)
“Virtue and vice suppose the freedom to choose between good and evil; but what can be the morals of a woman who is not even in possession of herself, who has nothing of her own, and who all her life has been trained to extricate herself from the arbitrary by ruse, from constraint by using her charms?... As long as she is subject to man’s yoke or to prejudice, as long as she receives no professional education, as long as she is deprived of her civil rights, there can be no moral law for her!”
—Flora Tristan (1803–1844)
“Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.”
—Rudolf Carnap (1891–1970)
