   • problems
     • Third variable problem
       • solution
         • manipulate genes
         • manipulate environment
   • given a constant, stable environment – genes matter.

2. Environment

   • gene determines range, epigenetics and non-heritable environments determine value
   • Education

   • Birth order
   • Practice
