Kevin Rudd should do his science homework
Wednesday, May 22, 2013

“Kevin Rudd’s new support for same-sex  marriage shows he does not understand science,” FamilyVoice research officer Ros Phillips said today.  

“For example, Mr Rudd wrongly claims that the ‘near universal findings of biological research for most of the post war period is that… a certain proportion of the community is born gay’.  No reputable geneticist believes this.

“Studies of identical twins show that where one twin is homosexual, the other is heterosexual in over 85% of cases – even though each has the same genes and hormone exposure in the womb.

“Clearly, no one is ‘born gay’ .  It is life experiences – which may occur at a very young age and be different for different people – that determine same-sex attraction,” Ros Phillips said.  “Moreover authoritative longitudinal studies show that most young people who are same-sex attracted in their teens no longer have those feelings a decade later.

“Kevin Rudd needs to take a crash course in Scientific Method 101: All test groups should be selected randomly (ie not volunteers) and matched with controls who are the same in every respect except the feature being tested. Both groups should be independently assessed.

“Mr Rudd ignores these fundamental principles when claiming that children raised by same-sex couples do as well as those in other types of families.  He cites a longitudinal study of US lesbian couple families, but apparently does not realise that the lesbians:

  • were volunteers, recruited from gay and lesbian venues 
  • knew the study’s political implications
  • did their own reports on the progress of their children, who were not assessed by independent observers
  • were mostly college-educated, with over 80% in professional or managerial roles, and almost entirely Caucasian
  • were compared with a control group with much lower educational and employment levels, randomly selected from the general US population.

 “Amazingly, this flawed study’s conclusion – that children raised by lesbian couples are better adjusted, with higher educational achievement and fewer behavioural problems – has been cited as a major reason for redefining marriage.  Fortunately, most modern science adheres to higher standards - otherwise we would still be driving around in horse-drawn buggies and computers would be a pipe-dream.

 “The reality is that valid research with properly matched controls and independent assessment shows that children do best when raised by their two natural married parents.”

Ros Phillips said Kevin Rudd should have another look at his Bible.  Jesus affirmed the words of Genesis chapters 1 and 2, saying In the beginning the Creator made them male and female and said, ‘For this reason a man will leave his father and mother  and be united to his wife and the two will become one flesh’.

“Marriage is an age-old recognition that  children are best raised by their natural parents with both male and female role models in a committed environment,” Ros Phillips said.  “Governments did not invent marriage, and they cannot change its natural, fundamental meaning of a man-woman union.”
