I think I may have a unique opportunity for a high-impact intervention.

My brother is a graduate from UNC School of the Arts, with experience in television. He has even worked on getting a show pitched to networks ("Systems," a medical drama about systemic racism in medicine). If we could get some funding from Open Philanthropy, we could pitch a show about humanity's long-term future (check out HaydnBelfield's post on ideas for such a project). The basic theory of change is that if such a show becomes sufficiently popular, it could bring about a culture shift where people place more emphasis on the long term, which would then influence politicians to address things like x-risks.

My question: how can I test this idea for impact? Are there some low-cost ways for me to test out my theory of change and decide if this idea is worth pursuing?

(Also, feel free to throw out any critiques you might have of my idea. All feedback is welcome!)
