The famous five stages of grief — denial, anger, bargaining, depression, acceptance — were taken as immutable truth for decades. Modern fMRI research and clinical psychology have revealed they are neither universal nor sequential. Grief looks far messier, and more individual, than any neat stage model can capture.

The five stages — denial, anger, bargaining, depression, acceptance — were treated as near-scripture for decades after Kübler-Ross published her landmark work on death and dying. Huberman acknowledges the genuine insight in her observations while making clear that neuroimaging has complicated the picture considerably. Brain imaging studies using fMRI, which tracks neural activity via blood flow, revealed something counterintuitive: the brain regions most powerfully activated during grief are those associated with motivation, craving, and pursuit — not the emotional processing regions the stage model would suggest. This reframes grief from a passive emotional journey through defined stages into an active, drive-like neurological state — one that explains the almost compulsive quality of yearning experienced after loss.
Grief and depression share symptoms like sleep disruption and appetite loss, but are distinctly different neurobiological processes.
Social norms compress behavior so effectively that we assume other minds are similar to ours. They almost never are. After running over 100 psychology studies, Greenberg's biggest finding is that humans are far more different from each other than we intuitively believe.
The widely shared claim that we have a credit card's worth of plastic in our brains may be a massive overestimate. Researchers used nitrile gloves to measure microplastics — and nitrile gloves shed microplastic particles onto the measuring device. A second paper found the original tool used was unreliable, and that we may have far less plastic than reported.
RSD isn't just hurt feelings — it's a dopamine-deficient brain with a hyperactive amygdala and a frayed connection to the prefrontal cortex. Add a surge of norepinephrine and you get chest pain, sweating, and trembling that convinces your body something catastrophic is happening.
In Dan Ariely's door experiment, participants sacrificed the highest-reward door — repeatedly — just to avoid seeing other doors disappear. Even when researchers trained them to use the best door, they kept wasting clicks to maintain options. This is the bias that runs our lives: we'll take a worse outcome to preserve the feeling of optionality.
Dan Gilbert discovered that the brain has a 'psychological immune system' — it misremembers, reframes, and rationalizes to keep you satisfied with whatever you chose. The fear before commitment is all about potential regret. But after committing, your brain quietly starts justifying the choice — and the more irreversible the decision, the stronger the effect.
The psychological immune system can get you through the first few months of any commitment. But durable, long-term well-being requires self-concordance — choosing commitments that are genuinely aligned with your values and what you actually want. Without that alignment, the satisfaction fades fast.
Vision didn't just help animals find food — it ignited the Cambrian explosion of speciation. Half of the human cortex is devoted to visual processing, and that same visual hierarchy directly inspired the neural network architectures powering today's AI.
Peptides come loaded with a powerful narrative: regenerative, subcutaneous, targeted, cutting-edge. That narrative can genuinely move outcomes, especially for pain, energy, and recovery. The RCT's job is to quantify how much additional benefit comes from the molecule itself — above and beyond the compelling story surrounding it.
A pharmaceutical is not an amino acid sequence — it is the successful solution to manufacturing, purification, formulation, and consistency challenges. When clinical trials prove a drug works, they validate a specific product under specific processes, not every preparation that shares the same sequence.
