How con artists use the Ouija board effect for their scams

In 1851, Michael Faraday secretly measured the muscle movements of Ouija board users who believed that the planchette was under ghostly control. According to Faraday, the users were unconsciously moving their muscles and but truly thought a spirit was pushing the planchette. A few decades later, physiologist William Carpenter dubbed this the "ideomotor effect." To this day, the ideomotor effect is a powerful phenomena and one that scammers have used to sell bogus "scientific" instruments. From the Wellcome Collection:

For example, in 2014, James McCormick, a British businessman, was convicted of selling fake bomb detectors to various international police forces. McCormick’s devices were marketed as using principles similar to dowsing, with extreme life-or-death stakes. The operator was supposed hold the device, called the ‘ADE 651’, like a wand, and allow its subtle movements to direct them towards dangerous substances.

The devices themselves have been determined to be entirely non-functional. But thanks in part to the ideomotor effect, they could easily feel functional, especially if the operator were confident in their legitimacy.

Since the late 1990s, non-functional detection devices with names such as ‘Sniffex’, ‘GT 200’ and ‘Alpha 6’ were sold by various scammers to governments throughout the world, including those of Iraq, Egypt, Syria, India, Thailand and Mexico. The World Peace Foundation of Tufts University, which tracks corruption related to international arms trading, estimates that fake bomb detectors generated more than $100 million in profit between 1999 and 2010.

Experiencing awe is linked to decreased inflammation

In the Savvy Pscychologist, clinician Ellen Hendriksen of Boston University’s Center for Anxiety and Related Disorders, looks at the profound psychological and physiological impacts of feeling awe, whether it comes from looking up at the expansive night sky or hearing an incredible musical performance. She reflects on scientific evidence that awe makes us "feel small" and humble, nicer, and expands our worldview, all of which seem like fairly obvious effects. But Hendriksen also points to a recent curious study published in the journal Emotion showing that "awe is linked to decreased inflammation." The University of Toronto researchers had examined whether amusement, compassion, contentment, joy, love, pride, and awe resulted in "lower levels of a marker of inflammation called interleukin-6, or IL-6, which has been linked to diseases as diverse as rheumatoid arthritis, lupus, and diabetes." From the Savvy Psychologist:

Why on earth might standing on a mountaintop connect with our levels of inflammation? One hypothesis is that proinflammatory cytokines like IL-6 lead to physical and social withdrawal—curling up in your den and resting speeds recovery from illness or injury more quickly than pushing through. By contrast, awe triggers the opposite: an urge to explore and experience more. It’s unclear whether awe reduces inflammation or reduced inflammation makes us seek out awe, but either way, the two seem to be linked.

Man has alligator as emotional support animal

Joei Henney, 65, of Strinestown, Pennsylvania has an alligator as his registered emotional support animal. According to Henney, the 5-foot alligator, named Wally, helps Henney manage his depression. Apparently, the reptile is very generous with his hugs. From the Philadelphia Inquirer:

A man who answered an e-mail from a reporter about Wally from the web site Service Dog Registration of America said, "Our therapist would never approve a client to have an alligator as an emotional support animal. "

Henney’s doctor did.

“My doctor wanted to put me on depression medicine, and I hate taking medicine. I had Wally, and when I came home and was around him, it was all OK," he said. “My doctor knew about Wally and figured it works, so why not?”

Wally, Henney cautioned, is still a wild animal, one that could tear his arm off now, and do worse later...

“He has never tried to bite no one,” Henney said. “I don’t push him on to people. I tell people to respect him, not fear him. He will not hurt you.”

Rigorous new scientific study: Link between kids screen time and their well-being is highly overstated

In a heavy-duty new scientific paper published this week, University of Oxford researchers argue that the association between adolescent well-being and digital technology use is tiny. Really tiny. From Scientific American:

(The paper by experimental psychologist Andrew Przybylski and grad student Amy Orben) reveals the pitfalls of the statistical methods scientists have employed and offers a more rigorous alternative. And, importantly, it uses data on more than 350,000 adolescents to show persuasively that, at a population level, technology use has a nearly negligible effect on adolescent psychological well-being, measured in a range of questions addressing depressive symptoms, suicidal ideation, pro-social behavior, peer-relationship problems and the like. Technology use tilts the needle less than half a percent away from feeling emotionally sound. For context, eating potatoes is associated with nearly the same degree of effect and wearing glasses has a more negative impact on adolescent mental health...

“We’re trying to move from this mind-set of cherry-picking one result to a more holistic picture of the data set,” Przybylski says. “A key part of that is being able to put these extremely miniscule effects of screens on young people in real-world context.”

Not surprisingly though, your mileage may vary. Not surprisingly, it all depends on the kid and what they're actually doing on the screen.

In a previous paper, Przybylski and colleague Netta Weinstein demonstrated a “Goldilocks” effect showing moderate use of technology—about one to two hours per day on weekdays and slightly more on weekends—was “not intrinsically harmful,” but higher levels of indulgence could be.

The neuroscience of creativity (and yes, right brain/left brain is mostly bullshit)

Anna Abraham literally wrote the book on creativity and the brain. The Leeds Beckett University psychology professor is the author of a new textbook titled The Neuroscience of Creativity. From an interview with Abraham by psychologist Scott Barry Kaufman in Scientific American:

SBK: Why does the myth of the “creative right brain” still persist? Is there any truth at all to this myth?

AA: Like most persistent myths, even if some seed of truth was associated with the initial development of the idea, the claim so stated amounts to a lazy generalization and is incorrect. The brain’s right hemisphere is not a separate organ whose workings can be regarded in isolation from that of the left hemisphere in most human beings. It is also incorrect to conclude that the left brain is uncreative. In fact even the earliest scholars who explored the brain lateralization in relation to creativity emphasized the importance of both hemispheres. Indeed this is what was held to be unique about creativity compared to other highly lateralized psychological functions. In an era which saw the uncovering of the dominant involvement of one hemisphere over the other for many functions, and the left hemisphere received preeminent status for its crucial role in complex functions like language, a push against the tide by emphasizing the need to also recognize the importance of the right hemisphere for complex functions like creativity somehow got translated over time into the only ‘creative right brain’ meme. It is the sort of thing that routinely happens when crafting accessible sound bites to convey scientific findings.

Is it better to read a book or listen to it?

Daniel Willingham, a University of Virginia psychologist who wrote "The Reading Mind," says that the most common question he receives these days is the following: “Is it cheating if I listen to an audiobook for my book club?” In a New York Times essay, Willingham parses the benefits and drawbacks of both formats. Which one is better? Of course personally preference and convenience matter, but Willingham argues that generally right now when it comes to listening or reading a book, there is "equivalence for easy texts and an advantage to print for hard ones." For example, audio books provide prosody, the intonation, tone, and rhythm of the words. Sometimes, hearing those cues helps us understand the material. But not always. From the NYT:

For example, one study compared how well students learned about a scientific subject from a 22-minute podcast versus a printed article. Although students spent equivalent time with each format, on a written quiz two days later the readers scored 81 percent and the listeners 59 percent.

What happened? Note that the subject matter was difficult, and the goal wasn’t pleasure but learning. Both factors make us read differently. When we focus, we slow down. We reread the hard bits. We stop and think. Each is easier with print than with a podcast.

Print also supports readers through difficult content via signals to organization like paragraphs and headings, conventions missing from audio. Experiments show readers actually take longer to read the first sentence of a paragraph because they know it probably contains the foundational idea for what’s to come.

Why some people hate Jews and Asian-Americans

Social psychologist Amy Cuddy and her colleagues have developed a "theory of prejudice" that goes deeper than a simplistic us-versus-them mindset. According to her research, when the world feels volatile or the economy is tanking, groups that are stereotyped as both "cold" ("unfriendly" and "untrustworthy") and "competent" ("ambitious, intelligent and skillful") are more likely to be targeted for, um, extermination. According to Cuddy's op-ed in the the New York Times, "a widespread stereotype of Jewish people, like that of other socioeconomically successful minorities such as Asian-Americans, falls in the competent-but-cold quadrant."

People assume that socioeconomically successful groups must be competent and that disadvantaged groups must be incompetent. Likewise, groups that are viewed as competitors — for status, for resources — get stereotyped as cold, whereas groups that are viewed as allies get stereotyped as warm...

In-groups and “cultural reference” groups (the middle class and Christians are common examples in the United States) are stereotyped as warm and competent — a wholly positive category. In stark contrast, groups on society’s margins who are blamed for their plight and viewed as a drain on resources (common examples include homeless people and drug addicts) are stereotyped as cold and incompetent — a wholly negative category. Discrimination against groups stereotyped in this way is typically expressed through disregard, stigmatizing and ostracizing...

But when times get tough, envious prejudices can ignite. Societal breakdown, harsh economies or political turmoil can activate resentment toward high-status minorities, who are seen as competitors for limited resources or even dangerous enemies.

Scientists study the psychology of death metal

Psychology professor William Forde Thompson of Australia's Macquarie University and his colleagues have published a series of scientific papers about the appeal of death metal. The scientists were surprised to learn that death metal fans aren't particularly angry or violent people and actually in a happy place whilst head-banging to the likes of Morbid Angel (above) and Cannibal Corpse (below). The research reminds me of how my dad was always so surprised at my love for goth music even though I was a generally happy teen. From Scientific American:

“It’s the paradox of enjoying a negative emotion that I was interested in,” says Thompson, a professor at Macquarie University in Sydney, Australia. “Why are people interested in music that seems to induce a negative emotion, when in everyday life we tend to avoid situations that will induce a negative emotion?” A number of studies have explored the emotional appeal of sad music, Thompson notes. But relatively little research has examined the emotional effects of listening to music that is downright violent.

Thompson’s work has produced some intriguing insights. The biggest surprise? “The ubiquitous stereotype of death metal fans—fans of music that contains violent themes and explicitly violent lyrics—[is] that they are angry people with violent tendencies,” Thompson says. “What we are finding is that they are not angry people. They’re not enjoying anger when they listen to the music, but they are in fact experiencing a range of positive emotions...."

Chris Pervelis, a founding member and guitarist of the band Internal Bleeding (whose songs include Gutted Human Sacrifice [below] and The Pageantry of Savagery), is confident that the positive emotions he experiences when he plays and listens to Death Metal are the real thing.

Enjoy this strange new audiovisual illusion from Caltech scientists

Caltech researchers developed the illusion above to illustrate postdiction, a sensory phenomenon "in which a stimulus that occurs later can retroactively affect our perceptions of an earlier event." From Caltech Matters:

"Illusions are a really interesting window into the brain," says first author Noelle Stiles (PhD '15), a visitor in biology and biological engineering and a postdoctoral scholar–research associate at USC. "By investigating illusions, we can study the brain's decision-making process. For example, how does the brain determine reality with information from multiple senses that is at times noisy and conflicting? The brain uses assumptions about the environment to solve this problem. When these assumptions happen to be wrong, illusions can occur as the brain tries to make the best sense of a confusing situation. We can use these illusions to unveil the underlying inferences that the brain makes...."

Postdictive processing has been demonstrated within individual senses, but this work focuses on how the phenomenon can bridge multiple senses. The key to both of the new illusions is that the audio and visual stimuli occur rapidly, in under 200 milliseconds (one-fifth of a second). The brain, trying to make sense of this barrage of information, synthesizes the stimuli from both senses to determine the experience, using postdiction to do so.

Sans Forgetica, a font to make you remember

Sans Forgetica is a free-to-download font that supposedly helps you "remember your study notes", designed by typographer Stephen Banham and the Royal Melbourne Institute of Technology's Behavioural Business Lab. It's a remakably hostile mindhack: the letterforms are designed to be difficult to read without losing their legibility, thereby "prompting your brain to engage in deeper processing" and "question the gestalt understanding of type".

I'd like it more if it were a deliberate prank, a typographical equivalent of the Jimmy Kimmel skit where he tricked Fashion Week attendees into praising a model wearing a watermelon on his head. It's called semiographic closure, honey, look it up. Read the rest

The art (and science) of lying

Now seems like a fine time to read this Scientific American article titled The Art of Lying by Theodor Schaarschmidt. According to a study conducted by UC Santa Barbara psychologist Bella M. DePaulo and referenced in the article, people make up around two stories every day. Apparently, children "initially have difficulty formulating believable lies, but proficiency improves with age. Young adults between 18 and 29 do it best. After about the age of 45, we begin to lose this ability." From Scientific American:

Current thinking about the psychological processes involved in deception holds that people typically tell the truth more easily than they tell a lie and that lying requires far more cognitive resources. First, we must become aware of the truth; then we have to invent a plausible scenario that is consistent and does not contradict the observable facts. At the same time, we must suppress the truth so that we do not spill the beans—that is, we must engage in response inhibition. What is more, we must be able to assess accurately the reactions of the listener so that, if necessary, we can deftly produce adaptations to our original story line. And there is the ethical dimension, whereby we have to make a conscious decision to transgress a social norm. All this deciding and self-control implies that lying is managed by the prefrontal cortex—the region at the front of the brain responsible for executive control, which includes such processes as planning and regulating emotions and behavior.
