Shows the political bias of the "scientists" in their interpretation of the data. If you research the amygdala, you find that it is not just associated with fear, but it is also associated with all emotions, such as love, and is also associated with processing of pleasure, and is associated with memory. A person with another political bias could say that conservatives experience pleasure better than liberals.
There's a simple reason for this. They don't like change. They "Fear" it. That's why there Conservatives.
