If you stopped eating eggs for fear it could raise your cholesterol, or you avoided giving peanuts to your toddler to prevent allergies, or you stayed away from hormone replacement therapy because you were told it could cause breast cancer — you are a victim of what Dr. Marty Makary calls “medical dogma.”

Long known as an iconoclast in the medical community, Dr. Makary’s latest book, “Blind Spots,” examines how health care can go so wrong. He chalks much of it to groupthink and a growing inability for science to identify its own biases.

His diagnosis? Humility.

“Medical science is about transparency and civil discourse. Great ideas and truths have always emerged from a healthy debate within the scientific community,” he tells Kerri Miller on this week’s Big Books and Bold Ideas. “And tragically, what we’ve seen in the modern era is a small group of people making the decisions for everybody — many times with a paternalist and hierarchical philosophy.”

When faced with the realities of climate change, marine biologists must hold two competing thoughts simultaneously: The seas are warming, the fish are waning, the corals are bleaching. But that doesn’t mean the global ocean is doomed. After all, this is the planet’s largest ecosystem. It knows how to adapt.

The question is really: Will we enable it or hinder it?

Helen Scales lives at the balance of those two intersecting points. A marine biologist, writer and broadcaster, Scales is honest about the scale of change. But as she tells Kerri Miller on this week’s Big Books and Bold Ideas, she believes it’s not too late. We still have time to figure out how to co-exist sustainably. Her new book, “What the Wild Sea Can Be,” explores practical solutions — like no-fish zones and banning undersea mining — that can give the planet’s oceans time to heal.
