Comparisons of Approaches
| Feature | Idiographic | Nomothetic |
|---|
| Strategy | Emphasizes uniqueness | Focuses on similarities |
| Goal | In-depth understanding of the individual | Identify universal traits |

| Advantages | Deep understanding of an individual | Generalizable insights |
| Disadvantages | Difficult to generalize | Superficial understanding |
