Q1. Since the assumption that everyone's brain is functionally the same is false, how can we report subjects' PRO data without examining their brains?
There is no contradiction between PRO and Brain-function-examining. PRO give researchers the information of subjects' opinion on the concept interested. By gathering PRO data, we can understand human's psychological construct as a unit or individually. Many factors can affect the PRO results whereas brain function is only one of them, other factors like SES also contributed to PRO. Therefore, we can say that the research of brain-function examining can give us another evident for explaining subjects' PRO data, but it is not necessary to examining subjects' brains before reporting their PRO data.
