Aaron Hartman, MD uses a historical anecdote about past belief that the earth was flat (ships 'eaten by sea monsters', misunderstanding of horizon, sunrises/sunsets) to illustrate how scientific understanding shifts paradigms. He links sudden explanatory advances (e.g., understanding nautical miles and the horizon) to paradigm shifts in medicine, mentioning 'PRISMA effect for psoriasis and sunsets' as part of the analogy and stating that medicine/science moves from paradigm to paradigm.
