A brain health researcher on chronic stress, polarized environments, information overload, and what discomfort can do for change.Dr. Delia McCabe studies chronic stress and anxiety. She opened our conversation with a study from 2010 on how people respond in polarized environments. Mark “Moose” McGrath and I asked her what stress and a flood of information do to the way we see the world.
Stress and perception
Delia explains how stress and anxiety change perception and feed cognitive biases. Technology and social media reinforce echo chambers. Discomfort can be a catalyst for change, and she asks listeners to resist demonizing the other side.
Information overload
We bring in Marshall McLuhan’s global village. Electronic media pulls us into the affairs of distant places. That load strains the brain’s finite capacity and affects how we decide. We talk about Dunbar’s number and how stress inside organizations can shut down creativity and innovation.
Body and brain
Delia connects physical health and brain function, from food systems to stress management. She talks about shifting mindsets and integrating care for the whole person. We also discuss psilocybin, and Delia stresses the need for experienced guidance.
We close on change, aesthetics, art and nature.
This episode is not medical advice. Psilocybin is a Schedule I substance in the United States. Talk with a licensed clinician about any treatment.
