Yep this BB agrees. By the bye, extensive long-term studies of twins brought up in the same household, twins separated at birth and brought up in different households, adopted children, siblings brought up in same household, siblings separated and brought up in different households have shown that parenting has absolutely minimal to zero effect on the outcome of these children as adults.
This is rubbish.
There is no way that this could be tested as you described, the confounders are unmistakable.
Genetics plays a small role, and nuture plays a MASSIVE role.
Looking at the wrong thing
genes always important
But they need environment
NOW THINK
what Environment
When they grow up who do children have to deal with
relate to.. survive among ?
There own peers
parents have a certain influence
esp on certain things
But it is the peer group
That children grow up in
That is the future that genes switch on or off to.
certainly many more weapons out there
also young people often seem to lead independent lives
Think-- Lord of the Flies
Parents can have one Big influence
from an early age
and that is
Being available & involved
and crafting to some extent that environment that matters
ie the Peer groups.....
It is not the parents that children have to adapt to and relate
But there own peers - Genes ( evolution ) are primed for this
You develop personality to fit in some way
& maximize self esteem --- What ever it takes ..
So genes and environment
But the one of Tomorrow that they will have to compete in
For you name it... Success , Money , Sex .. Love .. Security
esp SELF ESTEEM..
