Two strategies for combating mental fatigue
Research from Denmark finds that mindfulness and music help sustain attention.
- Four weeks of mindfulness training and 12 minutes of binaural beats were found to increase attentional capacities after being mentally fatigued.
- This research from the University of Southern Denmark provides important interventions during a stressful time.
- Mental fatigue leads to higher incidences of workplace and traffic accidents as well as an inability to retain information.
Mental fatigue is always a problem in our distraction-heavy world, but it's particularly troublesome as we constantly check for the latest updates on the state of our societal health. Specifically, mental fatigue occurs after extended periods of cognitive demand. This results in an inability to focus on tasks and can often lead to accidents and an inability to retain information.
Since the advent of the smartphone plenty of research has focused on helping us combat mental fatigue. In his bestselling book, Matthew B. Crawford suggests craftsmanship—he left a D.C. think tank to become a motorcycle mechanic—is as intellectually stimulating as it is physically demanding, improving attentional skills. For others, such as computer science professor Cal Newport, it means getting off of social media and only checking email once a day.
Fixing antique motorcycles or eschewing social media is not in everyone's cards, however. Thus, practices like meditation have entered the national conversation. Though some question its validity as a performance enhancement technique—they believe it should only be a tool for spiritual development and self-introspection—there's solid evidence that a regular practice offsets attentional deficits.

Then there's an intriguing new study from the University of Southern Denmark Faculty of Health Sciences. The team of Johanne L. Axelsen, Ulrich Kirk, and Walter Staiano (from the University of Valencia) discovered that the combination of mindfulness meditation and binaural beats helps combat mental fatigue and regain attentional abilities.
Binaural beats are two tones, one played in each ear at slightly different frequencies. An auditory illusion occurs when your brain produces a beat at the junction of those two frequencies. Thus far, research has been spotty on their efficacy. Most positive reviews have been anecdotal. For some people they seem to have no effect. For others (such as myself) they make a great accompaniment to a meditation practice. Beyond focus, binaural beats are said to help reduce anxiety, increase relaxation, and assist in creating positive moods.
Four groups were invited to partake in this research: a novice mindfulness group, an experienced mindfulness group, a binaural beats group, and a control group. For this study, the team conducted five phases:
- Volunteers' moods were assessed using the Brunel Mood Scale (BRUMS), after which they completed a sustained attention task (SART)
- They were given a 90-minute mental fatigue treatment using a AX-CPT task
- Their mood was again assessed, followed by immediate interventions
- One group listened to a 12-minute mindfulness meditation provided by Headspace; another group listened to 12 minutes of binaural beats; a third group was told to relax for 12 minutes
- Finally, each volunteer was again given a sustained attention task

The SART was designed to fatigue the groups. As the team writes,
"The results showed that the music group and the experienced mindfulness group were least affected by mental fatigue and its effect on the SART %NoGo success rate, whereas performance of the control group and the novice mindfulness group was reduced by mental fatigue."
Those with a longstanding mindfulness practice and a history of using binaural beats seem to maintain sustained attention even after being fatigued. Less experienced meditators are more easily tired, while those told "just relax" without a framework also fared poorly. The team found that four weeks of mindfulness training was enough to help combat cognitive exhaustion.
Such information is always useful, but especially so at this moment. Times of uncertainty are cognitively brutal. This is the first time in history that the entire world is experiencing an epidemic while being connected to social media. In some ways, it can be calming, but the opposite is also occurring, with conspiracy theories and misinformation rampant.
Unplugging, as Newport suggests, is great for your mental health, but let's face it: many of us will keep our eyes glued to the screen. Taking some time out, even 12 minutes, appears to help. Right now, we'll take progress in inches.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>

Answering the question of who you are is not an easy task. Let's unpack what culture, philosophy, and neuroscience have to say.
- Who am I? It's a question that humans have grappled with since the dawn of time, and most of us are no closer to an answer.
- Trying to pin down what makes you you depends on which school of thought you prescribe to. Some argue that the self is an illusion, while others believe that finding one's "true self" is about sincerity and authenticity.
- In this video, author Gish Jen, Harvard professor Michael Puett, psychotherapist Mark Epstein, and neuroscientist Sam Harris discuss three layers of the self, looking through the lens of culture, philosophy, and neuroscience.
