Unfortunately this minor content issue remains unresolved, despite our good faith attempts to try and resolve it here and indeed here https://en.wikipedia.org/w/index.php?title=Wikipedia:Reliable_sources/Noticeboard&diff;=604813004&oldid;=604812813. I have not reverted, and as I said, I am sure we can resolve this minor content dispute in a civil way, rather than edit war iss246? I think we just need clarification from an experienced editor/administrator specifically relating to Wikipedia:Identifying reliable sources and Wikipedia:No original research. As I said, my understanding of these policies is that if the 7 reliable sources provided above, all clearly state that Elton Mayo was a psychologist at some point in his career, we need to go with what those 7 published, reliable sources state. Especially if no other published reliable sources actually state that Mayo was not a psychologist.
