The history of brainwashing in America

An LSD scientist's role in a US mind control project

Within a decade of LSD's discovery, the US government had launched a secret initiative involving hypnosis and hallucinogens. LSD researcher Louis Jolyon West conducted experiments for the CIA's MKUltra project, which focused on the potential of mind control. He later took part in a criminal trial that hinged on testimony whose sourcing was seemingly inspired by MKUltra experiments. This article explores light shed by West's personal archive.

Retracing the 1960s history of dropping out

A core element of the 1960s counterculture was the idea of dropping out of school and the broader technocratic institutions at the time. This push coincided with paranoia over mind control during the Cold War, and as some rogue psychologists advocated for the liberating use of psychedelics.

Visualizing 11 cognitive biases that influence how you think

Humans are hardwired to make mental mistakes called cognitive biases, affecting the way we view our world. Among the most common are confirmation bias (seeking only evidence that affirms your views), authority bias (overweighting things said by authority figures), groupthink (assimilating ideas to avoid conflict), and more. This quick chart gives an overview of some of the most notable ways we mislead ourselves.

In 1968, a Harvard Medical School committee issued the first neurological definition of death

The definition set a legal and medical precedent for how we define death, important for issues including organ donation. This 2020 video podcast discusses the history of brain death controversies and the variability in how death has been determined, including discussions in the late 1960s about when patients are considered dead in the context of organ donations.

Fearology, or the study of fear, explores the difference between stress and fear

Our brains involuntarily respond to our environment and signal alarm when that isn't always needed, triggering responses that include goose bumps. But understanding fear and how to talk our brains into calming down can improve daily life.

How four types of psychedelics affect the brain

Brain imaging shows that ayahuasca, MDMA, DMT, and psilocybin profoundly affect neural activity, giving rise to higher states of introspection and consciousness. This article details exactly how each of these drugs physically affects the brain and what that means for mental health treatment. Some of these drugs quiet the brain or trigger the release of neurochemicals associated with mood regulation and learning.

The US government ran boarding schools designed to erase Native American identity

From the late 19th century into the 20th century, the federal government sent Native children to boarding schools under the philosophy of "kill the Indian, save the man." Children were forbidden from speaking their languages or practicing their cultures, and many endured abuse.

Psychedelics set off a flurry of brain activity that may permanently alter it

The brain seems to experience a sharp increase in communication between areas that generally don't interact. New research suggests a thin, sheet-like gray matter structure tucked deep within the brain, between the insular cortex and striatum, may be the key to this change. The area is centrally located and home to many of the receptors that psychedelics target, potentially rewiring the brain and rewriting thought patterns.

The history of skull modification

The ancient Maya people sometimes modified their skulls to appear more conical. Body modification has been a human pastime for literal ages, from piercings to bindings and everything in between. Modifying one's skull shape may have been a way to symbolize status, beauty, belonging, or belief. The health impacts of such practices are still debated. This article explores the history and health impacts of skull modification, also known as artificial cranial deformation.

Political science professors say dystopias are defined by government coercion

Shauna Shames and Amy Atchison, two political science professors and the authors of "Survive and Resist: The Definitive Guide to Dystopian Politics,” argue that defining a real-world dystopia depends on whether a government is using coercion to protect its citizens or to control them. Shames and Atchison seek to provide a more nuanced understanding of the word “dystopia,” one they note they began hearing more and more as the COVID-19 pandemic progressed.

Dystopian narratives have influenced real-life extremists

J.M. Berger, a senior research fellow at Middlebury’s Center on Terrorism, Extremism, and Counterterrorism, traced how terrorist organizations have latched on to dystopian narratives, with some groups even embracing the texts’ lexicons and iconographies.

How can octopuses and MDMA help scientists understand the human brain?

Research shows that psychedelics may induce something called "critical periods" in the adult brain, which can make our brains more open to learning and changing, like they once were back in early childhood. Psychedelics similarly change how social creatures like octopuses behave, which demonstrates that these animals could help us better understand our own neurobiology.

What it means to call something 'Orwellian'

The adjective often refers to anything that resembles the dystopian governments of George Orwell, usually a state like the one in "1984" that monitors its citizens to ensure compliance. But as this video essay from Noah Tavlin makes clear, the more precise definition is a society that redefines language to control thought.

The science of optical illusions

The human brain has developed cognitive shortcuts to help us navigate in a world where our visual senses are constantly bombarded of information. But these shortcuts can also be exploited, tricking the brain into telling us something is happening when it really isn't. This short video unpacks the neuroscience behind some of the most common (but perplexing) optical illusions.

An interesting perspective on whether (and how) brain size matters in cognitive ability

Some brains are bigger than others, but what is the relevance, if any, to brain size and intelligence? This Scientific American article explores the question and offers examples.
