Robin Reames was raised to be a Republican housewife, growing up in a conservative home in Louisiana.
Her father had an unshakable view of the world, no matter what the facts.
She saw first hand at the dinner table, why conspiracy theories flourish and how misinformation spreads.
Now a professor at the University of Illinois-Chicago, Reames believes the antidote is straightforward; we need to learn to think for ourselves.
Her new book explains how, it's called The Ancient Art of Thinking For Yourself: The Power of Rhetoric in Polarized Times.
