If you're going to talk
about biologically
determined aspects of human
behavior, in order to have
any hope of making any sense
you have to limit your
claims to the inheritance of      
fairly subtle, complex             
aspects...                        (or less charitably,
                                  perhaps "vague and  
We don't inherit a quality,       ill-defined").      
we inherit a capacity for a    
quality.  We don't have        
determined behavior, we have
tendencies toward certain       
types of behavior.             

                             

I was reading a recent article in "Science News" that
mentioned in passing that there were a number of twin
studies that showed inherited capacity for intelligence.  
                       
My first thought: "Whoa, they've
got twin studies data now?  That 
pretty much settles it."          
                        
My second thought: "What if a
bunch of the women putting
twins up for adoption have
also been doing drugs with an
adverse affect on fetal
development?  They could just
be measuring an inherited
stupidity, and not a
genetically inherited one at
that."
                
     I would actually
     need to look at 
     the details of  
     these twin      
     studies...      
                     
          You can't trust second 
          hand information in this 
          field at all...

If you happen to be a scientist
with an interest in investigating
the biological component of human
behavior, I certainly hope you get
your AAAS grant, but it often
strikes me that people exaggerate
how important the issue is.
                    
Some people want it
to be "nurture"  
because that
supposedly makes it
more flexible, but
is it really?
                      
    From a practical point of
    view you're pretty much  
    stuck with whatever       
    nurture you've got, and     The nurture of the
