10 Adorable Psychological Tricks Your Dog Uses to Score More Treats

As a proud dog owner, I can wholeheartedly say that my love for my dogs often surpasses my affection for most humans. It might sound odd, but if that’s being brainwashed, then I’m all for it! Who wouldn’t?

Many dog owners invest significant time and effort into training their pets. We encourage good behavior through rewards, such as treats and praise, leading to more consistent positive actions over time.

Your furry friend will learn essential commands like “come” and “sit.” However, the same training techniques can sometimes backfire.

For instance, my dog has picked up on the fact that the moment I sit down to work, he becomes a master at begging for attention. The only surefire way to quiet his antics is to reward him with treats.







In this delightful game of cause and effect, I feel trained—or dare I say brainwashed—but just look at how adorable he is; it’s hard to care!

Interestingly, some dogs are quite clever. According to one study, dogs can distinguish between “cooperative” people who provide treats and “competitive” ones who hoard them.

During the experiment, dogs guided cooperative individuals to food boxes while leading competitive ones to empty boxes, indicating a conscious choice to deceive potential non-supporters.

So, while our dogs seem to brainwash us, MRI studies reveal that they trigger activation in brain areas associated with rewards and social connections when interacting with their owners. Research suggests that dogs truly understand how to bond with us.

Thus, while neuroscientists may not definitively state that “dogs love us,” their findings imply a strong emotional connection.

How to Calculate Your Stress Score: Assess Your Stress Levels Effectively

Understanding your stress levels can often feel subjective, but advancements in technology are making it more measurable.

Many smartwatches are now equipped to assess your heart rate, offering a basic indicator of stress. The normal resting heart rate for adults ranges from 60 to 100 beats per minute. When stress occurs, the body releases cortisol and adrenaline, which can elevate this rate. A diminished capacity to recover from stress may lead to prolonged increases in heart rate.

Additionally, various smartwatches measure heart rate variability (HRV), which captures the natural fluctuations between successive heartbeats. Under stress, both cortisol and adrenaline cause your heart rate to quicken, leading to reduced variability. Conversely, when the parasympathetic nervous system activates to regain balance, heart rate fluctuations increase. Since average HRV varies from individual to individual, it’s advisable to track deviations as markers of stress.

Over time, monitoring your heart rate and HRV can yield a stress “score,” pinpointing activities or individuals that may contribute to excessive stress (refer to Why the right kind of stress is important for your health and well-being). However, these scores can be imprecise; recent research indicates that they may fail to differentiate between positive excitement and harmful stress.

Cortisol is another critical biomarker for stress researchers. However, its rapid increase—occurring roughly 20 minutes post-stressor—makes it less practical for immediate assessment. Research conducted by Julie Vashuk at Masaryk University in the Czech Republic requires saliva, urine, or blood samples for comprehensive analysis. A biosensor designed for continuous cortisol monitoring is under development, aiming for future commercial availability. Monitor cortisol functionality will enhance our understanding of stress.


In the near future, Vashuk predicts potential biomarker innovations might stem from bone cells. Under stress, these cells produce glutamate, which can inhibit the hormone osteocalcin.

This leads to an influx of osteocalcin in the bloodstream, decreasing parasympathetic activity and triggering a fight-or-flight response.

“We believe that under stress, the skeleton rapidly produces molecules that serve as better biomarkers for real-time conditions,” Vashuk mentions.

“These bone-derived substances play a significant role in directing energy to necessary areas,” she continues. “In the future, one of these molecules could emerge as a valuable biomarker for stress.”

Last year, I penned an article for New Scientist detailing how a physicist unveiled the precise method to flawlessly cook the Italian classic, cacio e pepe. The emulsion of black pepper, pecorino cheese, and water can often turn clumpy. Ivan di Terlizzi and his team at the Max Planck Institute for the Physics of Complex Systems experimented with cacio e pepe numerous times to perfect a method that guarantees consistent results.

This topic resonated with many readers. When I recently caught up with one of the scientists involved, he suggested the draw might stem from their research’s ability to unveil order in what can otherwise appear chaotic, especially when examined through the lens of mathematics and precision.

While this perspective is captivating, it also carries risks, as C. Thi Nguyen discusses in his book, Score: How to Stop Playing Someone Else’s Game. Formerly a food critic, Nguyen is now a philosophy professor at the University of Utah in Salt Lake City. He cautions that recipes promising flawless results can obscure the essential values of food as “an exercise of taste and preference.”

By employing scientific rigor—exact measurements and meticulous procedures—the outcomes might be repeatable, but this approach diminishes the diversity of culinary experiences and the delightful chaos that food can represent.

Cooking serves as merely one instance illustrating how modern tendencies to systematize and impose order on chaotic realities—often driven by state bureaucracies—can result in less-than-ideal outcomes. Nguyen constructs a vivid image of a world rife with such consequences.

Using his own academic journey as a reference, Nguyen contends with the rankings that universities and magazines impose. In philosophy, these ratings often derive from websites evaluating departments based on criteria like publishing prestige or scholars’ ability to address specialized queries, contrasting sharply with the “wild, unruly questions” that initially piqued his interest in philosophy. He began to sense a phenomenon he labeled “value capture,” where metrics intended to guide us begin to dictate our actions.

Nguyen argues for embracing these intricate rule-based systems by engaging in games as a means to explore and remain open to life’s experiences. This book encompasses a diverse array of his recreational pursuits, from Dungeons & Dragons to rock climbing, yoga, and yo-yo.

He effectively illustrates why choosing to abide by the rules within a game serves as a “spiritual vaccine” against societal pressures to conform to institutional scoring systems, like those found in educational assessments. While the notion that games can save us may seem optimistic, Nguyen compellingly presents it as a refreshing perspective.

Many of Nguyen’s concepts aren’t groundbreaking, drawing from numerous influential philosophers and scholars shaping his thought process—including Tim Marshall’s Prisoners of Geography, which explains the influence of geography on geopolitics, and James C. Scott’s Seeing Like a State, which scrutinizes the shortcomings of scientifically planned societies.

However, Nguyen’s imaginative approach to discussing the core themes of his book ensures the conversation remains engaging and thought-provoking. This work provides a compelling starting point for further exploration.

Your perceived intelligence may not align with your IQ score

In 1904, British psychologist Charles Spearman discovered a peculiar correlation among various mental abilities, such as mathematics, verbal fluency, spatial visualization, and memory.

He observed that individuals who excelled in one area tended to perform well in others, while those who struggled in one area also struggled in others. These findings have been extensively replicated and are considered some of the most replicated results in psychology.

Through statistical analysis, a single general intelligence factor known as ‘g’ can be derived, indicating an individual’s overall cognitive ability relative to others. This general intelligence is further divided into fluid intelligence (gf), reliant on abstract reasoning, and crystallized intelligence (gc), focused on learned experiences and vocabulary.

Research suggests that fluid intelligence peaks around age 20 and declines thereafter, while crystallized intelligence remains stable or improves with age. General intelligence is thought to have a hereditary component, with mental skills inherited from parents.


Intelligence Quotient (IQ) tests are tools used to estimate general intelligence (g). These standardized tests provide consistent results, indicating that individuals are likely to achieve similar scores across different tests. Various types of IQ tests assess different cognitive abilities but generally show that high performance in one mental task correlates with high performance in others.

Managed with statistical adjustments, raw IQ scores indicate that roughly 66 percent of people score between 85 and 115, with 2.5 percent scoring above 130 or below 70. Despite a historical rise in raw scores over decades, IQ tests have been shown to predict various outcomes, such as job performance, income, social status, and mortality.

While IQ tests have faced criticism due to their association with eugenics and other controversial topics, they remain reliable predictors of cognitive ability. However, intelligence encompasses more than just IQ, including emotional intelligence and rational thinking, which are crucial for decision-making.

High IQ does not necessarily equate to wisdom, rationality, or good life choices, highlighting the importance of considering other forms of intelligence. Rather than solely focusing on IQ, individuals should also develop emotional and rational intelligence for overall success.

This article addresses William Rawlings’ question on how IQ tests function.
