There may be some evidence here or it could be just random postulation, but I would like to pose a question and I would be curious to hear feedback.
If you were to compare the childhoods of FDR members to the average public would the be worse or better? Would there be certain threads that might make one more likely to not trust authority or question things? Is there a particular type of abuse or neglect that would be less present as that type would tend to be too much for the mind to then be able to transfer to these kinds of ideas?
Maybe there is no discernable differences, but it would be interesting to think about the histories of FDR members and what (if any) common threads there are. It could create bias in the ideas of members, make certain people more likely to be able to be reached or not, and many other possible implications.
I don't have any particular theories currently, so I am interested as to what others think.
Addition:
As a resource that might be helpful, people can self-asses the Adverse Childhood Experiences Test here:
