In this episode of Modern Wisdom, featuring Heather Berlin and Chris Williamson, Considering Consciousness | Dr Heather Berlin | Modern Wisdom Podcast 146 explores neuroscientist Explores Consciousness, Free Will, Psychedelics, and the Self Dr. Heather Berlin discusses what consciousness is, how subjective experience arises from the physical brain, and how much of our behavior is driven by unconscious processes. She explains current theories of animal and human consciousness, the neural basis of mental illness, and why mental disorders should be seen as brain-based conditions rather than personal failings.
Neuroscientist Explores Consciousness, Free Will, Psychedelics, and the Self
Dr. Heather Berlin discusses what consciousness is, how subjective experience arises from the physical brain, and how much of our behavior is driven by unconscious processes. She explains current theories of animal and human consciousness, the neural basis of mental illness, and why mental disorders should be seen as brain-based conditions rather than personal failings.
A major thread is how psychedelics like psilocybin and MDMA can therapeutically reshape entrenched patterns of thought and emotion, particularly in conditions like PTSD, anxiety, and depression. Berlin contrasts these one-off, experience-driven interventions with traditional daily medications such as SSRIs.
The conversation also delves into free will, showing how neuroscience suggests that the brain initiates decisions before we become consciously aware of them, and why the powerful illusion of free will is evolutionarily adaptive for social behavior and responsibility.
Finally, they explore the constructed nature of the self, how memory and brain development shape identity over time, and why embracing the full depth of conscious experience—including anxiety and existential reflection—may be preferable to “ignorant bliss.”
Key Takeaways
Consciousness is best defined as first-person subjective experience.
Berlin emphasizes that consciousness is simply what it feels like to see, taste, or feel something from the inside; experiments must ultimately rely on self-report because only the subject can say whether they were consciously aware of a stimulus.

Much of our behavior is unconsciously driven, and our explanations are often post hoc.
The brain is always active, with thoughts arising from ongoing neural fluctuations that cross a threshold into awareness; we then create narratives about why we acted or chose something, but these stories may not reflect the true underlying causes.

Mental disorders are disorders of the brain, not character flaws.
Experiences like anxiety or depression correspond to physical changes and dysfunctions in neural circuits; this alignment with other organ-based illnesses helps reduce stigma and supports treatments targeting both brain and thought patterns (e. ...

Neuroscience suggests decisions are initiated unconsciously before we ‘decide’.
Classic and modern experiments show brain activity predicting choices hundreds of milliseconds to seconds before conscious intention emerges, implying that we are ‘the last to know’ what our brain has already set in motion.

The illusion of free will and a continuous self is evolutionarily useful.
Believing we control our actions encourages ethical, socially responsible behavior; when people are told free will is an illusion, they cheat more in studies, indicating that the feeling of agency—though possibly illusory—supports cooperation, accountability, and long-term planning.

Notable Quotes
“The illusion of free will is actually very adaptive.”
— Dr. Heather Berlin
“Much of what we do, the decisions we make, our behaviors are being dictated by things that are happening outside of our awareness.”
— Dr. Heather Berlin
“We don't have free will, but maybe our unconscious does. The brain is deciding, but you are your brain, and we're just the last to know about it.”
— Dr. Heather Berlin
“If this is my one and only chance to just be conscious and experience things, then I want the fullest gamut of it all.”
— Dr. Heather Berlin
“You're a work in progress until your very last breath.”

But, you know, the studies show that when you tell people they don't have free will, like when you tell them about these neuroscience studies and then you test them after, they're more likely to behave unethically and to cheat on an exam.
Mm.
So, the illusion of free will is actually very adaptive. We've evolved to have this very strong sense of our control over our own agency for a reason. Because it helps us interact in social environments, right? If we know that we have control, if we think we have control of our actions and we are responsible for our actions, then we're going to behave in ways that are socially appropriate. If your, you know, if you think, "Well, it doesn't matter anyway. My brain's deciding." You know, I could just, like, kill this person and say, "My brain made me do it," right? So, the strong illusion of free will, it, it evolved for... It has a purpose.
I'm joined by the lovely Heather Berlin. Heather, welcome to the show.
Hi. Thanks for having me.
Pleasure to have you on today, talking about your daughter's stickers just behind you.
(laughs) .
They look good. I think they, they really-
Yeah.
... they really add something to the room.
Yeah. It's kind of like those cool tattoos that are, like, the little ones that are randomly, you know, dispersed, and it's just, it's that cool kind of look. Yeah.
Is that the same thing that happens when you have a child? They just start adding little flavor of personality into all of the rooms all over the house?
Pretty much. Pretty much, yeah. They slowly take over your life, and that's symbolic of that.
(laughs)
So, yeah. (laughs)
I love it. Um, so why don't you tell us what it is that you do? What do you spend your days thinking about and, and working on?
Okay. So, uh, I am a cognitive neuroscientist and psychologist, um, and I'm... I mean, fundamentally, the kind of driving force in my career has been trying to understand the fundamental question of how the physical brain creates our subjective awareness, so basically the neural basis of consciousness. Um, but, but I also got really interested in the neural basis of all of these unconscious processes that are motivating our behavior, because much of what we do, the decisions we make, our behaviors are being dictated by things that are happening outside of our awareness, and we're only consciously aware of a very small bit of what's actually happening. We often make up these, like, post hoc explanations about why we do things, but these are not necessarily the real reasons, so, you know, we have a narrative that we tell ourselves. Um, so I'm interested in both the kind of, how the physical brain creates our conscious experience and our subjective states as well as the unconscious processes that are, that are motivating us and explaining how we behave.
