Rational Thinking for Rational Rules. Porco advocates for dogma-free education and politics that emphasize logic and rational thinking. She has said, “What I cannot fathom in an educated, supposedly advanced society like ours, where so much information is readily available to us, is the deliberate refusal to access and evaluate the facts as we know them, and from there, in sober fashion, construct guidelines for decision-making and behavior based on them.”

The Scientific Method and Religion. As an advocate for the scientific method, Porco has said, “Its interesting to think about the scientific method as it applies to the existence of god. Because if someone were to give me the task of investigating the existence of god the way I would, say, investigate the motions of the bodies in the Saturn system, and required me to bring to bear on the matter all the training I had received about how to prove or disprove an idea, and then required me to write a scientific paper or publication on the subject, I can tell you right now that it would be a paper with no conclusions.”

Low Maintenance. Annoyed by a sexist question from a reporter who wanted to know why Porco never married in her life, Porco quipped, “There are no high maintenance items in my house of any kind – pets, plants, or husbands.”
