I believe a proper PhD education should allow one to dig into any subjects given enough time and examine them in great depth. It would help greatly in spotting misdirections and fallacies even in published research. Most of the PhDs I know are quite open to be convinced by sound reasoning even though they might disagree at first, and that is a great boon to societal decision making.

The issues of costs, ROI, and capabilities/interests do make it difficult to push everyone toward getting a PhD though.

Correlation is not causation. A potentially more likely explanation is that people more open to changing their mind are more likely to be willing and able to get a PhD.
