A news headline announces that a gene has been identified as a cause of depression. Does this mean that everyone with the gene will become depressed? How should critical thinkers interpret this research?

What will be an ideal response?

No, it means that people with the gene are more likely to become depressed when they undergo severely stressful experiences. Critical thinkers would want to make sure the research is replicated, and they would realize that not all cases of depression are necessarily influenced by genetics.
