P: Strong evidence supports a genetic link to schizophrenia.

E: Family studies show that the likelihood of developing schizophrenia increases with genetic closeness to a relative with the disorder. Twin studies show higher concordance rates for monozygotic (MZ) twins compared to dizygotic (DZ) twins.

E: This suggests a genetic component in schizophrenia, supporting the genetic explanation.

P: Genetic explanations may be confounded by environmental factors.

E: MZ twins often share more similar environments than DZ twins, potentially inflating concordance rates due to shared environmental influences rather than genetics alone.

E: This suggests that the genetic explanation is not fully sufficient and environmental factors must also be considered.

P: Genetic understanding can lead to early intervention.

E: Identifying individuals at genetic risk can help in monitoring and possibly preventing the onset of schizophrenia through early intervention strategies.

E: This practical application highlights the utility of genetic research in clinical settings.

P: Biological explanations are often criticized for being reductionist.

E: These explanations attempt to explain a complex disorder solely at the level of genetics, potentially neglecting the complex interplay of psychological, social, and environmental factors.

E: This reductionism can lead to an incomplete understanding of the disorder, emphasising the need for a more holistic approach.
