Cognitive Distortions: How to Stop Believing the Lies Your Brain Tells You

Dr. Tracey Marks introduces cognitive distortions as biased, negative, automatic, and inaccurate thought patterns that twist how individuals interpret events, often leading to significant distress. She explains that these "mental false alarms" are the brain's attempt at efficiency, creating shortcuts that, especially under stress, can be inaccurate. The amygdala, the brain's alarm center, becomes overactive, overriding the prefrontal cortex responsible for rational thinking. These distorted thoughts, if left unquestioned, are reinforced through neuroplasticity, making them easier to access in the future, but crucially, they can also be rewired through conscious effort and repetition.

The podcast distinguishes between genuine threats and imagined ones, emphasizing that while the brain's protective mechanisms are vital for real danger, they are unhelpful when applied to minor stressors like an unreturned text message. Dr. Marks outlines four common distortions: catastrophizing (jumping to the worst outcome), all-or-none thinking (black-and-white extremes), mind reading (assuming negative thoughts about oneself), and personalization (taking responsibility for things outside one's control). She clarifies that the goal is not to ignore real problems or adopt unrealistic positivity, but to critically evaluate one's perspective and differentiate between actual issues and imaginary fears.

To combat these distortions, Dr. Marks introduces the "evidence check" technique. When experiencing anxiety or distress from a thought, individuals are encouraged to pause and ask, "What's the evidence for this thought?" This involves actively seeking facts that support or contradict the thought, and considering alternative, innocent explanations for situations. The technique is supported by previous discussions on mindful awareness, which helps notice thoughts without getting swept away, and self-compassion, which fosters a kind, non-judgmental approach to one's own thinking patterns. The practice of the evidence check, even starting with one recurring worry, is presented as a powerful tool for mental self-management.

The broader implications of this practice include gaining more mental space, reducing time spent in emotional spirals, and building trust in one's ability to interpret situations clearly and compassionately. By consistently applying the evidence check, individuals leverage neuroplasticity to strengthen new, healthier brain pathways, thereby building resilience. The episode concludes by highlighting that while one cannot control every thought, one can choose whether to believe, question, or rewrite them, setting the stage for future discussions on interrupting thought spirals and further regulating the mind.

Your brain is lying to you.

Many of the thoughts that cause us the most distress aren't based on reality at all. They're cognitive distortions

Cognitive distortions are biased ways of thinking that twist how you interpret events.

They're like having a funhouse mirror in your mind that makes everything look scarier or more catastrophic than it really is.

When you experience stress or uncertainty, your amygdala, the brain's alarm center, lights up.

But just like these patterns get reinforced through repetition, they can also be rewired through repetition. You can teach your brain to think differently.

You don't have to believe every thought that pops into your head. You can learn to fact check your thoughts just like you would fact check information you read online.

What's the evidence for this thought?

The evidence check isn't about being unrealistically positive, either. It's about evaluating your perspective and separating real problems from imaginary ones.

Neuroplasticity doesn't care how big the change is. It cares how often you practice it.
