What a stupid study. Perfectly reflects the self absorption of the academic world with pseudo-importance, paid for by someone else. What does the childhood backstory of Marvel and DC comic characters tell us? That decades ago some illlustrators patched together dozens of heroes journeys in order to make some money for themselves and the publisher, and this perhaps was fleshed out some decades later by scriptwriters living in the LA bubble, to make money for themselves and the film company. In all cases influenced by personal world views and experiences, but mostly by weak story tropes and the financial urge to satisfy a demand. Nothing more.
