What possible impact does time/history have on your speculative theory as to the difference between LDS and Jews?

the second one deals more in line with the difference between those who are more culturally a Jew or LDS vs devoutly so. When we look at the representation in the fine arts vs as you clarified professional fields.

time/history of the two groups we are discussing and the non religious but cultural aspect of being part of those groups vs the religious aspect and how that impacts the same.

I think you have found yourself an at least imo extremely interesting basis for study. If I was a liberal arts student in my twenties I could see myself sinking my mental teeth into something like this.
