As a species, humans like to think that we are fully in control of our decisions and behavior. But just below the surface, forces beyond our conscious control influence how we think and behave: our genes.

Since the 1950s, scientists have been studying the influences genes have on human health. This has led medical professionals, researchers and policymakers to advocate for the use of precision medicine to personalize diagnosis and treatment of diseases, leading to quicker improvements to patient well-being.

But the influence of genes on psychology has been overlooked.

My research addresses how genes influence human psychology and behavior. Here are some specific ways psychologists can use genetic conflict theory to better understand human behavior โ€“ and potentially advance the treatment of psychological issues.

What do genes have to do with it?

Genetic conflict theory proposes that though our genes blend together to make us who we are, they retain markers indicating whether they came from mom or dad. These markers cause the genes to either cooperate or fight with one another as we grow and develop. Research in genetic conflict primarily focuses on pregnancy, since this is one of the few times in human development when the influence of different sets of genes can be clearly observed in one individual.

Typically, maternal and paternal genes have different ideal strategies for growth and development. While genes from mom and dad ultimately find ways to cooperate with one another that result in normal growth and development, these genes benefit by nudging fetal development to be slightly more in line with what’s optimal for the parent they from. Genes from mom try to keep mom healthy and with enough resources left for another pregnancy, while genes from dad benefit from the fetus taking all of mom’s resources for itself.

When genes are not able to compromise, however, this can result in undesirable outcomes such as physical and mental deficits for the baby or even miscarriage.

Some scientists theorize that genes operate in their own self-interest.

While genetic conflict is a normal occurrence, its influence has largely been overlooked in psychology. One reason is because researchers assume that genetic cooperation is necessary for the and well-being of the individual. Another reason is because most human traits are controlled by many genes. For example, height is determined by a combination of 10,000 genetic variants, and skin color is determined by more than 150 genes.

The complex nature of psychology and behavior makes it hard to pinpoint the unique influence of a single gene, let alone which parent it came from. Take, for example, depression. Not only is the likelihood of developing depression influenced by 200 different genes, it is also affected by environmental inputs such as childhood maltreatment and stressful life events. Researchers have also studied similar complex interactions for stress- and anxiety-related disorders.

Prader-Willi and Angelman syndromes

When researchers study genetic conflict, they have typically focused on its link to disease, unintentionally documenting the influence of genetic conflict on psychology.

Specifically, researchers have studied how extreme instances of genetic conflict โ€“ such as when the influence of one set of parental genes is fully expressed while the other set is completely silenced โ€“ are associated with changes in behavior by studying people who have Prader-Willi syndrome and Angelman syndrome.

Prader-Willi and Angelman syndromes are rare genetic disorders affecting about 1 in 10,000 to 30,000 and 1 in 12,000 to 20,000 people around the world, respectfully. There is currently no long-term treatment available for either condition.

These syndromes develop in missing one copy of a gene on chromosome 15 that is needed for balanced growth and development. Someone who inherits only the version of the gene from their dad will develop Angelman syndrome, while someone who has only the version of the gene from their mom will develop Prader-Willi syndrome.

What do genes have to do with psychology? They likely influence your behavior more than you realize
Prader-Willi and Angelman syndromes both involve mutations to a specific gene on chromosome 15. Prader-Willi results from the suppression of the paternal version of the gene, while Angelman results from the suppression of the maternal version of the gene. Paternally expressed genes are marked in blue, maternally expressed genes in red, and genes expressed from both in pink.

Physical hallmarks of Angelman syndrome include major developmental delays, intellectual disabilities, trouble moving, trouble eating and excessive smiling. Physical hallmarks of Prader-Willi syndrome include diminished muscle tone, feeding difficulties, hormone deficiencies, short stature and extreme overeating in childhood.

These syndromes represent one of the few instances where the influence of a single missing gene can be clearly observed. While both Angelman and Prader-Willi syndromes are associated with language, cognitive, eating and sleeping issues, they are also associated with clear differences in psychology and behavior.

For example, with Angelman syndrome smile, laugh and generally want to engage in social interactions. These behaviors are associated with an increased ability to gain resources and investment from those around them.

Children with Prader-Willi syndrome, on the other hand, experience tantrums, anxiety and have difficulties in social situations. These behaviors are associated with increased hardships on mothers early in the individual’s life, potentially delaying when their mother will have another child. This would therefore increase the child’s access to resources such as food and parental attention.

Genetic conflict in psychology and behavior

Angelman syndrome and Prader-Willi syndrome highlight the importance of investigating genetic conflict’s influence on psychology and behavior. Researchers have documented differences in temperament, sociability, mental health and attachment in these disorders.

The differences in the psychological processes between these syndromes are similar to the proposed effects of genetic conflict. Genetic conflict influences attachment by determining the responsiveness and sensitivity of the parent-child relationship through differences in behavior and resource needs. This relationship begins forming while the child is still in utero and helps calibrate how reactive they will be to different social situations. While this calibration of responses starts at a purely biological level in the womb, it results in unique patterns of social beahaviors that influence everything from how we handle stress to our personalities.

Since most scientists don’t consider the influence of genetic conflict on human behavior, much of this research is still theoretical. Researchers have had to find similarities across disciplines to see how the biological of genetic conflict influences psychological processes. Research on Angelman and Prader-Willi syndromes is only one example of how integrating a genetic conflict framework into psychological research can researchers an avenue to study how our biology makes us uniquely human.The Conversation

Election anxiety doesnโ€™t need to win โˆ’ here are 3 science-backed strategies from a clinical psychologist to rein in the stress

Uncertainty about the election getting to you? Is anxiety the dominant feature of your emotional landscape, maybe with a small sprinkling of impending doom?

You are not alone. A recent survey found 69% of American adults are seriously stressed about the 2024 presidential election.

It’s difficult not to be worked up about politics in today’s polarized climate. Regardless of which side of the political aisle you sit on, you may find yourself glued to your browser or TV, gobbling up every tiny tidbit of and feeling your stress levels skyrocket.

I’m a psychologist who develops and tests strategies for combating anxiety. As I constantly tell my stressed-out clients, when it to election news, there’s a fine line between being well informed and being oversaturated with information.

If you’re ready to short-circuit your stress spiral, here are three science-backed strategies for coping with anxiety in times of uncertainty.

Approach your emotions with mindfulness

Being mindful refers to the quality of awareness you bring to your experiences โ€“ specifically, nonjudgmental attention focused on what’s happening right now.

Mindfulness practices originated in Eastern spiritual traditions, Buddhism. Over the past several decades, mindfulness has gained popularity as a powerful tool for managing anxiety. For instance, meditation apps such as Headspace and Calm incorporate it. Even if meditation isn’t your thing, though, you can still apply nonjudgmental awareness, focused on the present, to election-related anxiety.

Be present. Anxiety can draw you into an uncomfortable spiral of โ€œwhat-ifsโ€ about the future. When you make a point to be present, you remind yourself what is actually happening right now, rather than letting hypothetical fears take over.

Although you may have serious concerns about the fate of the nation, those outcomes have not yet to bear. As I tell my , โ€œWe’ll cross that bridge if we come to it. For now, focus on the step right in front of you.โ€

If you notice yourself getting carried away by of the future, you can pull yourself back to the present by bringing awareness to simple sensations โ€“ the feel of your feet on the floor, the rhythm of your breath, or the sounds around you โ€“ and remind yourself that you are safe in the current moment.

Pay nonjudgmental attention. Many people are hard on themselves for feeling strong emotions. This critical mindset might look like telling yourself that you’re overreacting, or that it’s weak to let others see that you’re upset. You might even view that uncomfortable feeling in the pit of your stomach as evidence that negative outcomes are right around the corner.

Making judgments about your emotions only serves to make you feel worse. In fact, researchers find that pushing away emotions or beating yourself up for having them leads to more frequent and stronger anxiety.

Instead, try giving yourself a break. Tell yourself, โ€œThis election is high stakes, so it makes sense I’m anxious.โ€ Then, notice if your anxiety is driven by a fear about the future, and bring yourself back to the present.

Get flexible with your thinking

Cognitive flexibility is the ability to shift away from rigid, all-or-nothing thinking about the future.

When people are anxious, they tend to focus on the worst-case scenario. For example, you might be telling yourself, โ€œWith this candidate in office, things will be terrible and I won’t be able to cope.โ€

In this scenario, I encourage my patients to move past that initial thought of how awful it will be and instead consider exactly how they will respond to the inauguration, the next day, week, month and so on.

Cognitive flexibility allows you to explore how you will cope, even in the face of a negative outcome, helping you feel a bit less out of control. If you’re experiencing a lot of anxiety about the election, try thinking through what you’d do if the undesirable candidate takes office โ€“ thoughts like โ€œI’ll to causes that are important to meโ€ and โ€œI’ll attend protests.โ€

Choose your actions with intention

Another tool for managing your anxiety is to consider whether your behaviors are affecting how you feel.

Remember, for instance, the goal of 24-hour news networks is to increase ratings. It’s in their interest to keep you riveted to your screens by making it seem like important announcements are imminent. As a result, it may feel difficult to disconnect and take part in your usual self-care behavior.

Try telling yourself, โ€œIf something happens, someone will text me,โ€ and go for a walk or, better yet, to bed. Keeping up with healthy habits can reduce your vulnerability to uncontrolled anxiety.

Post-Election Day, you may continue to feel drawn to the news and motivated to show up โ€“ whether that means donating, volunteering or protesting โ€“ for a variety of causes you think will be affected by the election results. Many people describe feeling guilty if they say no or disengage, leading them to overcommit and wind up overwhelmed.

If this sounds like you, try reminding yourself that taking a break from politics to cook, engage with your family or friends, get some work done or go to the gym does not mean you don’t care. In fact, keeping up with the activities that fuel you will give you the energy to contribute to important causes more meaningfully.The Conversation

in the digital world can be rewarding. It’s convenient to order groceries for pickup, share photographs or music, and keep in touch with and friends, no matter the distance. However, it can also be draining. The feeling of being constantly โ€œonโ€ and productive has driven people to reconsider their balance in the saturated digital world.

More than 70% of American adults are concerned about how technology affects their mental health and personal relationships. This worry is reinforced through that point to people’s unhealthy habits with social media and phones.

What to do? There is a fuzzy line between healthy and unhealthy digital consumption. Some folks feel the need to fully disconnect from the digital world to understand this boundary. The idea of digital detoxing is gaining popularity. This practice involves intentionally unplugging from digital technologies in the pursuit of balance and digital well-being. Nearly half of Americans report that they are making a conscious effort to regularly step away from their screens.

But is this attempt enough? It’s no surprise that 62% of Americans confess to feeling addicted to their devices and the internet. Despite people’s best efforts to unplug and strike a balance, research indicates that digital detoxes often fall short.

Digital well-being is subjective. We research technology and consumer behavior. Our recent research studied the digital detox journey, where people take a much-needed break from digital consumption, aiming to uncover what supports or sabotages those seeking digital well-being. Our findings highlighted four key strategies to improve the outcome of this journey toward achieving a healthier digital balance: replacement practices, social bonds, mindfulness and digital well-being as a journey.

1. Finding replacement practices

We found that feelings of withdrawal during a digital detox are quite common. For many, reaching for their phones and scrolling has become such a ritual that they often don’t realize they are doing it. Many turn to their devices when bored or stressed, much like an adult pacifier. As a result, finding an alternative to distract your mind and occupy your hands can be crucial during a digital detox.

These replacement practices often involve hobbies or activities that result in play. As adults, people sometimes forget what it feels like to have fun. By separating fun from your task list and engaging in play for its own sake, you can significantly reduce stress levels and boost your digital well-being.

2. Shoring up social bonds

Humans are inherently social creatures. Indeed, tools such as email, text messages and social media offer ways to enhance social connections. This innate desire for connection, however, combined with people’s reliance on technology, can lead to feelings of FOMO โ€“ fear of missing out โ€“ and anxiety during a digital detox.

The average adult now spends 70% less time with friends than they did two decades ago. Digital devices offer connection, but pieces of the experience are missing, such as the joy of in-person contact and trust in others that can be difficult to get online. So while we’re a more connected society, relationships suffer and people are more lonely than ever.

Therefore, during a digital detox it is vital to fill your cup with community, whether through existing friendships or by creating new ones. We recommend engaging in a digital detox alongside others, because FOMO may rear its ugly head if your friend pulls out their phone during a night out.

3. Emphasizing mindfulness

In ‘s fast-paced , finding a moment to pause can feel nearly impossible. Many experience solitude deprivation, meaning people often don’t have moments to be alone with their own . Yet, the ability to just be can allow time for reflection, helping you consider what makes you happy and healthy. Finding moments where you can step away โ€“ to be still and silent โ€“ can a much-needed recharge.

With adults spending about 90% of their time indoors, breaking the routine and heading outside can offer a more holistic perspective on both personal and global well-being. In our study, yoga and meditation were common ways that detoxers found moments to become more aware of their own thoughts, which helped foster more intentional behaviors.

4. Viewing digital well-being as an ongoing journey

Ultimately, digital well-being is a journey. It is not a checklist that, once completed, means you are fulfilled.

Unfortunately, a single detox isn’t enough to cure digital imbalance. Instead, a successful detox often leaves people feeling introspective and curious. Our research participants shared that relapses are common, especially if they don’t set and monitor ongoing goals. Importantly, your needs change and evolve over time. In other words, what works now might not be what you need in the future.

Willpower just isn’t enough. We recommend identifying specific goals for yourself related to your own digital well-being. These aren’t productivity goals but goals to be unproductive. The aim is to unplug in more fulfilling ways. Whether planning a weekly night with friends or taking a 10-minute walk without your phone, making time to unplug is worth it in the long .

Researchers still have more to learn to help support digital wellness. We should remember, though, that individual differences play a crucial role in this equation, meaning that the journey to achieving digital harmony is uniquely personal. Thus, as people navigate their tech-saturated lives, it’s clear that finding the right balance is a complex, highly individualized process.

The digital detox journey can be challenging, but many people discover it to be rewarding in the end. People are not machines, however, so recognizing your limits and finding ways to reconnect with yourself and others during a detox can significantly enhance your sense of humanity and digital well-being.The Conversation

โ€˜Safe routeโ€™ or โ€˜sushi routeโ€™ โˆ’ 2 strategies to turn yuck to yum and convince people to eat unusual foods

What will the diets of the future look like? The answer depends in part on what foods Westerners can be persuaded to eat.

These consumers are increasingly being told their diets need to change. Current eating habits are unsustainable, and the global demand for meat is growing.

Recent years have seen increased interest and investment in what are called alternative proteins โ€“ products that can replace typical meats with more sustainable alternatives. One option is cultivated, or cultured, meat and seafood: muscle tissue grown in labs in bioreactors, using animal stem cells. Another approach involves replacing standard meat with such options as insects or plant-based imitation meats. All of these products promise a more sustainable alternative to factory-farmed meat. The question is, will consumers accept them?

I’m a philosopher who studies food and disgust, and I’m interested in how people react to new foods such as lab-grown meat, bugs and other so-called alternative proteins. Disgust and food neophobia โ€“ a fear of new foods โ€“ are often cited as obstacles to adopting new, more sustainable food choices, but I believe that recent history offers a more complicated picture. Past shifts in food habits suggest there are two paths to the adoption of new foods: One relies on familiarity and safety, the other on novelty and excitement.

Disgust and the yuck factor

Disgust is a strong feeling of revulsion in response to objects perceived to be contaminating, polluting or unclean. Scientists believe that it evolved to protect human beings from invisible contaminants such as pathogens and parasites. Some causes of disgust are widely shared, such as feces or vomit. Others, including foods, are more culturally variable.

So it’s not surprising that self-reported willingness to eat insects varies across nationalities. Insects have been an important part of traditional diets of cultures around the world for thousands of years, the ancient Greeks.

Many articles about the possibility of introducing insects to Western or American diners have emphasized the challenges posed by neophobia and โ€œthe yuck factor.โ€ People won’t accept these new foods, the thinking goes, because they’re too different or even downright disgusting.

If that’s right, then the best approach to win on the plate for new foods might be to try to make them seem similar to familiar menu items.

The safe route to food acceptance

During World War II, the United States government wanted to redirect its limited meat supply to troops on the front lines. So it needed to convince home cooks to give up their steaks, chops and roasts in favor of what it called variety meats: kidneys, liver, tongue and so on.

To figure out how to shift consumer habits, a team of psychologists and anthropologists was charged with studying how food habits and preferences were formed โ€“ and how they could be changed.

The Committee on Food Habits recommended stressing these organ meats’ similarity to available, familiar, existing foods. This approach โ€“ call it the โ€œsafe routeโ€ โ€“ focuses on individual attitudes and choices. It tries to psychological and practical barriers to individual choice and counteracts beliefs or values that might dissuade people from adopting new foods.

As the name suggests, the safe route tries to downplay novelty, using familiar forms and tastes. For example, it would incorporate unfamiliar cuts of meats into meatloaf or meatballs or grind crickets into flour for cookies or protein bars.

The sushi route

But more recent history suggests something different: Foods such as sushi, offal and even lobster became desirable not despite but because of their novelty and difference.

Sushi’s arrival in the postwar U.S. coincided with the rise of consumer culture. Dining out was gaining traction as a leisure activity, and people were increasingly open to new experiences as a sign of status and sophistication. Rather than appealing to the housewife preparing comfort foods, sushi gained popularity by appealing to the desire for new and exciting experiences.

By 1966, The New York Times reported that New Yorkers were dining on โ€œraw fish dishes, sushi and sashimi, with a gusto once reserved for corn flakes.โ€ Now, of course, sushi is widely consumed, available even in grocery stores nationwide. In fact, the grocery chain Kroger sells more than 40 million pieces of sushi a year. Whereas the safe route suggests sneaking new foods into our diets, the sushi route suggests embracing their novelty and using that as a selling point.

Sushi is just one example of a food adopted via this route. After the turn of the millennium, a new generation of diners rediscovered offal as high-end restaurants and chefs offered โ€œnose to tailโ€ dining. Rather than positioning foods like tongue and pigs’ ears as familiar and comforting, a willingness to embrace the yuck factor became a sign of adventurousness, even masculinity. This framing is the exact opposite of the safe route recommended by the Committee on Food Habits.

The future of alternative proteins

What lessons can be drawn from these examples? For dietary shifts to last, they should be framed positively. Persuading customers that variety meats were a necessary wartime substitution worked temporarily but ultimately led to the perception that they were subpar choices. If cultivated meat and insects are pitched as necessary sacrifices, any gains they make may be temporary at best.

Instead, producers could appeal to consumers’ desire for healthier, more sustainable and more exciting foods.

Cultivated meat may be โ€œsafe-lyโ€ marketed as nuggets and burgers, but, in principle, the options are endless: Curious consumers could sample lab-grown whale or turtle meat guilt-, or even find out what woolly mammoth tasted like.

Ultimately, the chefs, consumers and entrepreneurs seeking to remake our food don’t need to choose just one route. While we can grind insects into protein powders, we can also look to chefs cooking traditional cuisines that use insects to broaden our culinary horizons.The Conversation
