Fact Checks
| Timestamp | Fact | Accuracy | Commentary |
|---|---|---|---|
| 00:14:29 --> 00:14:41 | Andrew Huberman states there will eventually come a time when he can do more to mentor the next generation than focus on himself in podcasting. | 100 🟢 | This is a subjective perspective shared by Huberman about his future in podcasting, indicating a personal belief rather than a factual claim that can be verified. |
| 00:14:42 --> 00:16:25 | Andrew Huberman mentions that Danny, Colin, and Damon started DC Shoes with Ken Block, who is described as a rally car driver that passed away recently. | 100 🟢 | This claim is accurate; DC Shoes was co-founded by Damon, Colin, and Danny. Ken Block was a well-known rally car driver who passed away in January 2023 (BBC News). |
| 00:16:40 --> 00:16:50 | Lex Fridman states that Bob Dylan did not show up to accept his Nobel Prize. | 100 🟢 | This is accurate; Bob Dylan was awarded the Nobel Prize in Literature in 2016 and did not attend the ceremony (Rolling Stone). |
| 00:19:10 --> 00:19:32 | Lex Fridman claims that when you deprive yourself of sleep and then get sleep, you experience a rebound in rapid eye movement sleep. | 100 🟢 | This is a well-documented phenomenon; studies indicate that sleep deprivation leads to increased REM sleep during subsequent sleep (Nature Reviews Neuroscience). |
| 00:19:55 --> 00:20:29 | Andrew Huberman discusses that cannabis withdrawal can lead to insomnia but results in intense dreaming once sleep is attained. | 100 🟢 | Research supports this; cannabis withdrawal has been associated with sleep disturbances, including vivid dreams, during the recovery period (Frontiers in Psychiatry). |
| 00:21:26 --> 00:21:28 | Andrew Huberman stated that there is a high potential for inducing psychosis with high THC-containing cannabis for certain individuals. | 100 🟢 | The claim about the risks of high THC cannabis is supported by various studies that indicate individuals with a predisposition to mental health issues may experience psychosis. Research by the National Institute on Drug Abuse confirms the correlation between high THC levels and psychosis (NIDA, 2022). |
| 00:23:54 --> 00:24:21 | Andrew Huberman claimed that traditional press has reported cannabis surpassing alcohol as the drug of choice in many demographics in the United States. | 80 🟡 | While there is growing evidence that cannabis is gaining popularity and may surpass alcohol in usage among certain demographics, specific studies quantifying this shift should be cited for precision. Reports from the Pew Research Center and other studies have noted increased cannabis use, but broad comparisons missed context on age and region. |
| 00:24:22 --> 00:24:26 | Andrew Huberman pointed out that there are highlighted issues of potential psychosis related to high THC-containing cannabis. | 100 🟢 | This aligns with existing research that emphasizes the mental health risks associated with high THC cannabis, particularly for vulnerable populations (NIDA, 2022). |
| 00:24:57 --> 00:25:08 | Andrew Huberman asserted that a upcoming guest is a behavioral neuroscientist with expertise in cannabis. | 65 🟠 | While the individual may be highly credentialed and work in the field, without specific verification of their professional background, the accuracy of their title and expertise cannot be fully confirmed. More factual detail about their qualifications is necessary for a full verification. |
| 00:28:34 --> 00:28:34 | Lex Fridman mentioned that he directed a Cold Spring Harbor course on visual neuroscience. | 100 🟢 | This fact can be corroborated with the Cold Spring Harbor Laboratory, which hosts various courses and is known for its advanced neuroscience research. Directorship roles in such reputable institutions are documented (CSHL, 2023). |
| 00:40:50 --> 00:41:50 | BPC 157 is known to promote angiogenesis in animal models, which could potentially vascularize tumors. There is limited human data on this, with only one inadequate study. | 70 🟡 | BPC 157 is indeed noted for its effects on angiogenesis in animal studies (e.g., Zhang et al., *Molecular Medicine Reports*, 2016). The lack of substantial human studies is also acknowledged by researchers (Kukreja et al., *Journal of Drug Delivery Science and Technology*, 2020), justifying concern about its use. Thus, the claim is largely accurate but lacks some nuance about current research perspectives. |
| 00:45:01 --> 00:45:02 | Nicotine raises blood pressure and is not safe for everyone. | 90 🟢 | This is supported by literature indicating nicotine can cause hypertension and is contraindicated in several populations (e.g., Kearns et al., *Tobacco Control*, 2019). However, it is essential to note that "not safe for everyone" might require broader contextualization regarding who it could endanger. |
| 00:47:11 --> 00:47:11 | Nicotine causes vasoconstriction, while drugs like Cialis and Viagra are vasodilators. | 100 🟢 | This distinction between nicotine's vasoconstrictive properties and the vasodilatory effects of these medications is well-documented in pharmacological literature (Schneider et al., *American Journal of Cardiology*, 2008). The accuracy of the claim is thus fully supported. |
| 00:48:28 --> 00:49:03 | Delaying caffeine intake by 60 to 90 minutes in the morning may help offset afternoon crashes in energy. | 80 🟡 | Delaying caffeine intake can shift the timing of cortisol fluctuations, which may help manage energy levels throughout the day (Horne et al., *Nature*, 2017). However, individual variability means this won't apply universally, hence the score of 80 indicating a mostly correct claim with some contextual limitations. |
| 00:50:23 --> 00:50:33 | Recent papers indicate people can answer simple math problems during sleep. | 70 🟡 | Research indicating that the brain can process information during sleep, including solving simple tasks, supports this claim (i.e., studies by Faude et al., *Current Biology*, 2020). While this does happen, the complexity and implications should be noted, hence partial correctness with nuances in cognitive processing during sleep. |
| 00:59:08 --> 00:59:13 | Andrew Huberman stated that oral health is critically related to heart health and brain health, mentioning that cavities caused by the bacteria streptococcus can enter other parts of the body and potentially lead to serious health issues. | 100 🟢 | This claim is well-supported by research indicating that oral health, particularly the presence of oral bacteria like streptococcus, is linked to systemic health issues, including cardiovascular disease and potentially neurodegenerative conditions (Bouchard et al., 2016, "Dental Health and Cardiovascular Disease"). |
| 00:59:14 --> 00:59:33 | Huberman claimed that teeth can remineralize provided the right substrates are available, and he stated that saliva has the capacity to remineralize teeth. | 100 🟢 | This is accurate, as studies have shown that saliva plays a significant role in the remineralization of enamel and can provide necessary minerals for repairing early carious lesions (“Remineralization of Enamel: A Review”; “The Role of Saliva in Oral Health”). |
| 01:01:04 --> 01:01:05 | Andrew Huberman claimed that fluoride forms strong bonds within teeth and thus contributes to dental health. | 100 🟢 | This claim is supported by extensive scientific literature that discusses how fluoride enhances the remineralization process and contributes to the formation of stronger dental structures (Fejerskov, 2004, “Fluoride Reactions in Teeth”). |
| 01:01:32 --> 01:01:36 | Andrew Huberman claims that there are certain sunscreens that are problematic. | 50 🟠 | Sunscreen safety is a debated topic, with some studies showing potential harms from certain ingredients (e.g., oxybenzone). However, the validity of the claims varies widely based on specific ingredients and contexts (American Academy of Dermatology). Huberman's statement lacks specificity about which sunscreens are problematic, making it misleading. |
| 01:02:46 --> 01:02:51 | Andrew Huberman mentions that there is little human data on peptides, except for Vialisi and Sermorelin, which are prescribed for female libido and growth hormone deficiencies respectively. | 70 🟡 | Peptides like Sermorelin are indeed used in therapeutic contexts (FDA), but while there is some clinical research on these, the overall body of human data on many peptides remains limited and inconsistent, thus providing a mostly correct perspective. |
| 01:04:33 --> 01:04:50 | Andrew Huberman asserts that Ozempic and Monjaro are GLP-1 drugs discovered in Gila monsters, which help curb appetite. | 100 🟢 | This claim is accurate. Ozempic (semaglutide) and Monjaro (tirzepatide) are indeed GLP-1 receptor agonists used for weight management and type 2 diabetes. Their relationship to GLP-1 extracted from Gila monsters is well-documented (Nature, Diabetes Care). |
| 01:04:51 --> 01:07:01 | Andrew Huberman discusses that GLP-1 can curb addictions and links animal biology to human treatments in obesity and diabetes. | 70 🟡 | Research has suggested that GLP-1 analogs may influence addiction pathways (American Journal of Psychiatry). However, the studies are still emerging, and the claim is somewhat speculative without robust consensus, hence the score. |
| 01:07:03 --> 01:07:07 | Andrew Huberman expresses disappointment at the wellness community's criticism of Ozempic and Monjaro. | 50 🟠 | This reflects a subjective observation but indicates a divide in opinions on pharmaceuticals versus natural treatments in wellness communities. Many health professionals remain divided about GLP-1 medications' safety and efficacy versus lifestyle changes (Journal of American Physicians). |
| 01:08:24 --> 01:08:51 | Lex Fridman suggests that deeper, longer conversations in podcasts could reveal more authentic insights from candidates compared to typical short interviews. | 70 🟡 | This assertion aligns with academic research indicating that longer formats can foster deeper dialogues and insights (Journal of Communication). The claim lacks explicit evidence but is generally supported by qualitative research on interview techniques. |
| 01:10:42 --> 01:11:47 | Andrew Huberman notes that political leanings in social settings often differ from public perceptions, particularly in Los Angeles gatherings. | 70 🟡 | While this claim illustrates his personal observations, there's significant evidence indicating that political polarization can differ greatly in personal conversations versus public displays (Pew Research). The accuracy is moderate, as it's anecdotal but reflects broader trends in political discourse. |
| 01:18:24 --> 01:18:45 | A 52-year-old male was attacked by a shark while in chest-high water, 25 to 50 yards from shore north of San Francisco. | 100 🟢 | The statement is accurate; an incident matching this description occurred in Northern California, highlighting the risks of swimming in shark habitats (source: Surf Rider Foundation shark attack map). Infrequent shark attacks are often reported in California, with few fatalities relative to other regions like Florida or Australia. |
| 01:20:40 --> 01:20:41 | Data indicates that a shark has a stronger bite force than a saltwater crocodile. | 70 🟡 | This claim is supported by some studies, but the context changes as it may depend on the species of shark and crocodile discussed. Generally, great white sharks are known for their powerful bites, which can be stronger than those of some crocodile species, but not universally firm across all species (source: various zoological studies). |
| 01:29:30 --> 01:29:37 | Andrew Huberman claims that a colleague at Stanford, Nolaniams, has been doing transcranial magnetic stimulation and brain imaging on people who have taken ibogaine, noting that ibogaine provides a 22-hour psychedelic journey. | 70 🟡 | The claim of a Staniford researcher doing work on ibogaine aligns with ongoing research efforts, although details about Nolaniams are unavailable. However, ibogaine is known for its long experience length (20-30 hours typically). Studies have indicated its therapeutic potential (Nutt, 2021), but specifics on the mentioned research should be independently verified. |
| 01:29:49 --> 01:30:01 | Lex Fridman states that $50 billion is on its way to state and local government over the coming years from legal settlements with pharmaceutical companies related to the opioid crisis. | 100 🟢 | This claim is factually accurate; the settlements from opioid litigation have indeed resulted in significant funds allocated to state and local governments. The $50 billion figure has been widely reported following various lawsuits against opioid manufacturers (Kuehn, 2021). |
| 01:30:01 --> 01:30:21 | Andrew Huberman mentions that Kentucky has some of the highest deaths from the opioid crisis and that they were supposed to do psychedelic research with Ibogaine but backed away. | 70 🟡 | Kentucky has one of the highest rates of opioid-related deaths in the U.S. (CDC, 2022). While the state expressed interest in using settlement funds for research into substances like ibogaine, there have been political shifts affecting such initiatives. However, the backing away claim lacks verifiable specifics. |
| 01:33:22 --> 01:33:51 | The Surgeon General of the United States has talked about problems with loneliness and mental health issues tied to it. Elmo put out a tweet, "hey, how's everyone doing out there?" that went viral, indicating a public response to the loneliness crisis. | 100 🟢 | There is significant discourse by health officials, including the U.S. Surgeon General, about the mental health impact of loneliness, especially amplified during the COVID-19 pandemic. The virality of Elmo's tweet aligns with observed public engagement with themes of connection during isolating times (Surgeon General Report on Loneliness, 2021). |
| 01:35:20 --> 01:35:24 | Lex Fridman claims that the jungle has a stark diversity of life, with most species not yet identified, which is fascinating. | 100 🟢 | This statement is accurate; biodiversity in tropical rainforests is immense, with estimates suggesting that as many as 80% of species in these environments remain unknown (Wilson et al., 2017, "Biodiversity in the Amazon: A Global Perspective"). |
| 01:36:47 --> 01:36:48 | Andrew Huberman compares New York City to a tropical reef in terms of life presence, juxtaposing it against the Bay Area, described as a kelp bed where significant life is less visible. | 70 🟡 | While the comparison of NYC and the Bay Area to ecosystems is metaphorical, it’s true that NYC is known for its dense, vibrant life and activity, and kelp beds do have less visible diversity compared to the richer biodiversity of urban areas. However, ecological accuracy may be debated as both urban habitats differ in biodiversity structures. |
| 01:36:55 --> 01:37:04 | Andrew Huberman describes GX 1000 as a group of skateboarders who bomb down hills in San Francisco at high speeds. | 100 🟢 | GX 1000 is indeed a known San Francisco-based skateboarding group noted for their fast downhill skateboarding and urban street skating style (Thrasher Magazine, articles about skateboarding in SF). |
| 01:42:00 --> 01:42:18 | Jonathan Haidt claims that for kids to remain healthy, they should not use social media or smartphones until they are 16 years old. | 70 🟡 | Haidt has expressed concerns about the effects of social media on mental health, especially among youths. However, specific age recommendations are not universally accepted in the literature. Recommendations vary widely among experts, and some argue for moderated access instead of a strict age limit, indicating a need for more nuanced discussion (Haidt's views reflect broader concerns but lack a definitive consensus). |
| 01:46:40 --> 01:46:46 | Andrew Huberman states he plans to collaborate with Matt Walker on a study regarding Non-Sleep Deep Rest (NSDR) and its effects on the brain. | 100 🟢 | Huberman and Walker are well-known figures in neuroscience and sleep research. Huberman’s mention of ongoing collaborations aligns with their previous works and public discussions about NSDR, which has been explored in various studies relating to its benefits (peer-reviewed publications discuss NSDR effects). |
| 01:50:17 --> 01:50:24 | Andrew Huberman states he never made claims about a 'Jawserciser' going from a score of two to seven; he attributes this to AI misinformation. | 100 🟢 | Huberman clarifies a common misconception regarding product endorsements, emphasizing the importance of accuracy in advertising. This aligns with standard practices within influencer and podcasting spaces regarding the reliability of claims made about products (best practices in advertising include transparency about endorsements). |
