The document presents three hypotheses about how cheap and ubiquitous data could change fields like health. Hypothesis A suggests that cheap data may change what constitutes justified beliefs in a field by prioritizing data-driven metrics over narrative models. Hypothesis B argues that data is becoming cheap and democratized enough to drive epistemic changes in health. Hypothesis C posits that costs may not automatically decline with more data and that certain experiments should be tried to see if data sharing works to benefit health. The document then outlines plans for portable legal consent and experiments with open data sharing groups in health research.
