Speaker 1 Summary

Wirth claims that if researchers are correct in their findings, it must be false that some people are predisposed to manic-depression. As support, Wirth explains that no “manic-depression gene” has been identified, and that most researchers agree that no such gene exists.

Speaker 2 Summary

Chang disagrees with Wirth’s conclusion, meaning Chang believes that the researchers’ results are compatible with a predisposition to manic-depression. How so? Because although researchers haven’t found a single gene responsible, they have identified multiple genes whose interactions can predispose someone to manic-depression.

Objective

We’re looking for a point of disagreement. One disagreement between Wirth and Chang is whether current research findings indicate that people can be predisposed to manic-depression or not.
