Case study extensive observation of particular client or small group, detailed reporting: pros study rare phenomena in depth, cons can be misleading, lacks scientific rigor/no control group, low internal validity and external validity. Identical twins have the same dna: genetic linkage and association studies discovers which genes are involved, shows us what kinds of genes, first looks at genes we already know about and have a link to disorders.
