Problems Investigating Nature-Nurture
- Ethical Restrictions -It would be ethically challenging to rear two identical twins separately in order to establish the relative influence of nature and nurture.
- Control - Controlled experiments are virtually impossible. For example, how can you isolate all “nurture” influences. When establishing relationships between parents and children you still can not conclude that nature is having an influence because it could be that similarities are down to the way in which children are brought up.
- Nurture can affect Nature! - The environment can change the way our bodies work. For example, drug and alcohol abuse can affect the way in which our brains function.
