On a crisp autumn morning in 2018, a Silicon Valley software engineer, whom we'll call Alex, meticulously placed a minuscule 10-microgram tab of LSD under his tongue. Alex wasn’t seeking a psychedelic trip; he was microdosing. The aim? To enhance his cognitive performance and creativity without the hallucinogenic effects associated with full doses of LSD. Alex represents a growing number of individuals curious about whether microdosing psychedelics like LSD or psilocybin could sharpen their minds or even boost their IQ.

Microdosing involves consuming sub-perceptual amounts of psychedelic substances, typically around one-tenth of a recreational dose. Advocates claim benefits ranging from improved mood to enhanced problem-solving abilities. But does the science support these anecdotes?
The Neurochemical Landscape
When a person ingests a psychedelic compound, even in small amounts, their brain chemistry undergoes subtle changes. LSD and psilocybin primarily exert their effects by acting on serotonin receptors, particularly the 5-HT2A receptor. This receptor, when activated, is known to play a role in cognitive flexibility—the mental ability to switch between thinking about two different concepts or to think about multiple concepts simultaneously.
A study conducted by the University of California, Davis in 2019 found that psychedelics, including LSD, enhance the growth of dendritic spines, which are small protrusions on neurons that facilitate synaptic connections. This structural change could potentially underpin the observed enhancements in cognitive flexibility. While these findings are promising, translating dendritic spine growth into tangible improvements in IQ or cognitive function requires further exploration.
Anecdotal Evidence and the Placebo Question
In 2020, researchers at Imperial College London conducted an intriguing study involving 191 participants. The study aimed to determine whether microdosing psychedelics had effects beyond the placebo. Participants who believed they were microdosing showed greater improvement in psychological well-being and creativity, regardless of whether they had ingested a placebo or the actual psychedelic. This raises an interesting question: are the benefits of microdosing primarily due to placebo effects?
While anecdotal reports like Alex's claim enhanced focus and problem-solving ability, it's crucial to recognize the powerful role of expectation in shaping subjective experiences. In the absence of robust double-blind studies, the placebo effect cannot be discounted.
IQ and Cognitive Flexibility: The Case of Psilocybin
Psilocybin, the active ingredient in magic mushrooms, is another psychedelic often used for microdosing. Its potential effects on IQ and cognitive flexibility have drawn significant attention. A pivotal study by researchers at Maastricht University in 2021 examined the effects of microdosing psilocybin on cognitive flexibility. Participants completed a series of cognitive tasks designed to measure flexibility, including the Wisconsin Card Sorting Test. Results indicated that those who microdosed performed significantly better on tasks requiring flexible thinking compared to the control group.
However, the study did not measure IQ directly, leaving open the question of whether these observed improvements in specific cognitive tasks translate to overall increases in IQ scores. IQ tests are designed to measure a range of cognitive abilities, including memory, reasoning, and verbal comprehension, and the direct impact of microdosing on these areas remains under investigation.
The Intersection of Creativity and Intelligence
Creativity and intelligence, while related, are distinct constructs. Microdosing enthusiasts often report boosts in creative thinking, an area less frequently assessed in traditional IQ tests. A 2018 study conducted by the Beckley Foundation explored the effects of microdosing on creativity. Participants reported enhanced divergent thinking—a key component of creativity that involves generating multiple solutions to a problem. This suggests that microdosing may influence specific cognitive processes more than others.
Understanding the relationship between creativity and intelligence is complex. While a highly creative individual may not score exceptionally high on an IQ test, the ability to think creatively is a valuable cognitive asset in many fields, particularly those requiring innovation and problem-solving.
Ethical and Legal Considerations
Despite the growing interest, microdosing remains a legal gray area in many countries. LSD and psilocybin are classified as Schedule I substances in the United States, indicating a high potential for abuse and no accepted medical use. This classification poses significant barriers to scientific research and raises ethical considerations around self-experimentation.
Researchers like Dr. Robin Carhart-Harris at Imperial College London argue for reform in drug policy to facilitate research on psychedelics' therapeutic potential. However, until legal barriers are addressed, individuals like Alex must weigh the potential cognitive benefits against the legal risks and ethical implications.
A New Frontier in Cognitive Enhancement?
As we navigate the possibilities of microdosing, it's essential to balance enthusiasm with scientific skepticism. Current research offers intriguing insights into how psychedelics might influence certain cognitive processes, yet definitive conclusions about their impact on IQ remain elusive.
The journey into understanding psychedelics and cognition is far from over. As researchers continue to untangle the complex interactions between brain chemistry, cognitive function, and subjective experience, one question lingers: could microdosing represent a new frontier in cognitive enhancement, or are we merely witnessing the placebo effect at play? As we ponder this, the allure of psychedelics in the quest for heightened intelligence and creativity remains a compelling narrative waiting to be fully understood.
