The conversation moves into specific harmful substances, and Palmer is emphatic and specific. THC, the active compound in marijuana, interacts with brain receptors throughout the body, impairs mitochondrial function, causes measurable cognitive and motivational decline, and epidemiological data suggests it increases the risk of developing schizophrenia or bipolar disorder by approximately four times. [1] — Dr. Chris Palmer "THC impairs mitochondrial function, causes measurable cognitive and motivational decline, and raises the risk of developing schizophrenia o…" 36:00 He uses the image of the unmotivated, unbothered teenage boy in his parents' basement as a clinical illustration, not a moral judgment. On vaping, he makes a nuanced harm-reduction concession — if you are smoking cigarettes and can't stop, switching to vaping is marginally better — but warns that nicotine concentrations in vapes are often stratospherically higher than in cigarettes, deepening addiction. Alcohol, he adds, tells a similar story to THC: not good for brain, not good for metabolic health.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
