- Gives insights into personality variation among twins, despite of having the same DNA
- Idea about 'Nature vs Nurture', to study how birth & environmental factors shape the cognitive & behavioural aspects of twins
- Analysis of heritability of traits, & factors affecting individual differences in ageing
Probable abuses due to inappropriate evaluation & conclusion of study :
- Intentional & wilful exposure to different environment for both the twins
- Psychological distress to a child if the child is raised in a separate, different environment.
