Your Brain Learns Fear Every Time You Avoid It
November 4, 2026
Avoidance works remarkably well in the short term: it lowers discomfort almost immediately. The problem is that every escape teaches the brain that the thing you avoided was dangerous, making the next encounter harder. Dr. Luana Marques has spent two decades at Harvard Medical School studying how evidence-based psychological skills can help people approach discomfort instead and how those same skills can be taken beyond the therapy room to communities that rarely get access to high-quality mental health care.
You get an email from your boss saying, “We need to talk.” Nothing has actually happened yet, but your body reacts anyway.
Your heart rate changes. Your mind starts filling in the blanks. And suddenly there is a very tempting option: avoid the conversation, distract yourself, scroll for a while, do something, anything that makes the discomfort disappear.
It works, but that is precisely the problem.
We’re looking back on this episode of Neural Compass with Mark Jacobstein, where we explore why avoidance can become one of the most powerful forces keeping anxiety, depression, and fear in place and what happens when we train the brain to move toward discomfort instead.
Mark speaks with Dr. Luana Marques, whose work at Harvard Medical School and Massachusetts General Hospital has spent more than two decades connecting the science of cognitive behavioral therapy with the realities of everyday life. Her interest is not simply in what makes CBT effective in controlled studies, but in how its core skills can reach people who may never sit across from a specialist.
This conversation examines why anxiety itself may not be the central problem; why the quick relief of avoidance can reinforce fear over time; how “opposite action” teaches the brain that discomfort can be tolerated; and why living according to your values can matter more than trying to eliminate unpleasant emotions altogether. Luana also explains why productive procrastination can look like achievement while still keeping us away from the thing that matters most.
They also turn to one of the biggest structural problems in mental health care: moving effective treatments into the spaces where people actually need them. Luana says research can take roughly 17 years to reach practice and that only 14% of scientific findings make it there. Her response was to build programs that translate CBT from a specialist therapy into practical skills that paraprofessionals, schools, nonprofits, and community organizations can teach.
The result is a conversation about mental health at two levels at once: how one person can retrain their response to fear, and how a healthcare system can put those same evidence-based skills into far more hands.

About the Guest:
Dr. Luana Marques is a clinical psychologist and Associate Professor at Harvard Medical School whose work focuses on bringing evidence-based mental health skills out of academic research and into everyday settings.
At Massachusetts General Hospital, she founded and directs Community Psychiatry PRIDE, a program focused on closing the gap between psychological science and clinical practice, particularly in communities with limited access to high-quality mental health care. Her research has examined how cognitive behavioral therapy can be translated into practical skills that can be taught by paraprofessionals and community organizations without losing the core principles that make the treatment effective.
She is also the author of Bold Move, which draws on two decades of clinical practice and research to argue that anxiety and discomfort are not necessarily what keep people stuck. The more consequential problem is often avoidance.
Episode Highlights
[00:03:33] Why Avoidance, Not Anxiety, Keeps People Stuck
Dr. Luana Marques explains that anxiety and fear are not necessarily what prevent people from moving forward. The real problem is often how they respond to those feelings. Avoidance provides immediate relief but teaches the brain to fear similar situations in the future, creating a cycle that can reinforce anxiety and depression.
[00:20:10] Rewiring The Brain Through Opposite Action
Dr. Marques breaks down how opposite action helps people confront discomfort rather than retreat from it. By taking small steps toward situations they would normally avoid, individuals can train their brains to tolerate distress. She also explores how timely, personalized AI reminders could help patients practice these skills between therapy sessions.
[00:27:25] Making Mental Health Skills Accessible Beyond Therapy
Dr. Marques shares how her team adapted cognitive behavioral therapy into practical skills that community workers can teach without years of clinical training. In one study involving young men leaving prison, participants who used at least one of the skills were 65% more likely to remain employed. Her work suggests that expanding access to evidence-based mental health support requires teaching these skills far beyond traditional clinical settings.
