nature vs nurture Options

[*tweeak*]

what do you think controls the way a person develops?

are people born athletic, or evil, or whatnot and theyll be that way however theyre raised or will can the personality of a person be changed by how there reared, like with gay people?

this is a fairly common debate, so you should be able to have some idea what im on about, i hope

Here's information taken from the book Genome; the autobiography of a species in 23 chapters, by matt ridley. harper collins publishers, 1999. On page 82-3:

Started by environmental determinists, the study of twins reared apart was later taken up by those on the other side of the argument, in particular Thomas Bouchard of the University of Minnesota.  Beginning in 1979, he collected pairs of separated twins from all over the world and reuited them while testing thier personalities and IQs.  Other studies, meanwhile, concentrated on comparing the IQs of adopted people with those of thier adoptive parents and thier biological parents or thier siblings.  Put all suchs studies together, totting up the IQ tests of tens of thousands of individuals, and the table looks like this, one hundred percent correlation being perfect identity and zero per cent being random difference.

The same person tested twice            87[%]
Identical twins reared together            86[%]
Identical twins reared apart                76[%]
Fraternal twins reared together          55[%]
Biological siblings                                  47[%]
Parents and children living together    40[%]
parents and children living apart          31[%]
Adopted Children living together            0[%]
Unrelated people living apart                  0[%]

[ % symbols added for clarity]

it is clearly obvious that Nature plays the largest role, as identical twins reared apart (same genes) are 76% alike, while adopted children living together are 0% alike (same upraising)


edit:

have i killed all debate in this thread? someone go research and find something at supports nurture, i garuntee you will find something, or else ther would not be an argument in the scientific society.

or just someone come here and tell me my cited (albiet not correctly cited) source is wrong.
