President Trump's Tariff Policies Cause Market Turmoil

on Literature
On April 4, 2025, President Donald Trump’s aggressive tariff policies sent shockwaves through global financial markets, triggering widespread turmoil and stoking fears of an economic downturn. The administration’s decision to impose sweeping tariffs—ranging from a 10% baseline on all imports to targeted rates as high as 50% on key trading partners like China, Canada, and Mexico—marked a dramatic escalation in Trump’s long-standing pledge to reshape U.S. trade. While the president touts these measures as a means to boost domestic manufacturing and reduce the $1.2 trillion goods trade deficit, the immediate fallout has been a steep market sell-off, with the S&P 500 plunging nearly 5% in a single day, its worst performance since June 2020. The tariffs, unveiled in a White House address, aim to retaliate against perceived trade imbalances and practices like currency manipulation. Trump argues they will force companies to relocate production to the U.S., creating jobs and strengthenin...

Why do we check the fridge multiple times, expecting something new to appear?

on

 It’s a familiar scene: you open the fridge, scan its contents, close the door, and then, minutes later, find yourself peeking inside again, hoping for something new. Despite knowing the inventory hasn’t changed, this repetitive behavior is surprisingly common. So, why do we keep checking the fridge, expecting something new to appear? The answer lies in a mix of psychology, biology, and modern habits, revealing fascinating insights about human behavior.


The Psychology of Habitual Checking

At its core, repeatedly checking the fridge is a habit driven by psychological triggers. According to Charles Duhigg, author of The Power of Habit, habits form through a cue-routine-reward loop. The cue might be boredom, stress, or hunger pangs, prompting the routine of opening the fridge. The reward? A fleeting sense of possibility or comfort, even if no new snacks materialize. Over time, this loop becomes automatic, reinforced by the brain’s dopamine system, which craves novelty and reward. Each fridge check delivers a tiny dopamine hit from the anticipation of finding something satisfying, even if the shelves remain unchanged.

This behavior mirrors other modern habits, like checking smartphones for notifications. Psychologists call this “intermittent reinforcement,” where unpredictable rewards—like the slim chance of spotting a forgotten treat—keep us hooked. A 2018 study in Behavioral Neuroscience found that dopamine spikes are stronger when outcomes are uncertain, explaining why we return to the fridge despite knowing it’s likely empty of new options.

Biological and Evolutionary Roots

Our fridge-checking habit also has biological underpinnings. Humans evolved as foragers, wired to seek food in uncertain environments. Anthropologist Daniel Fessler notes that our ancestors frequently revisited food sources, like berry bushes, hoping for new growth. The modern fridge, stocked with potential rewards, taps into this primal instinct. Hunger or even mild appetite can amplify this drive, as the brain’s hypothalamus signals a need for energy, nudging us toward the kitchen.

Interestingly, this behavior isn’t just about physical hunger. Emotional states like stress or boredom can mimic hunger signals, a phenomenon called “hedonic hunger.” A 2020 study in Appetite found that people are more likely to seek food during emotional lows, even if they’re not physically hungry, explaining late-night fridge raids during stressful times.

The Role of Environment and Culture

Modern environments amplify this tendency. Kitchens are often the heart of the home, making the fridge an easy target for restless wandering. In a 2021 survey by LG Electronics, 62% of respondents admitted to checking their fridge “out of habit” multiple times daily, especially when working from home. The proximity of fridges, coupled with their role as a food hub, makes them a default destination.

Cultural factors also play a part. In consumer-driven societies, we’re conditioned to expect abundance and instant gratification. Advertisements and social media showcase endless food options, creating an unconscious expectation that something new should appear. This mindset clashes with the reality of a static fridge, yet the hope persists, fueled by our optimism bias—the belief that things might turn out better than expected.

Breaking the Cycle

While checking the fridge multiple times is harmless for most, it can lead to mindless snacking or wasted time. To curb the habit, experts suggest addressing the cue. If boredom is the trigger, try engaging in a new activity, like reading or a quick walk. For hunger-driven checks, keeping a food journal or pre-planning meals can help. Rearranging the fridge to highlight healthy options can also shift behavior, as a 2019 study in Journal of Consumer Research found that visible, appealing foods are more likely to be chosen.

Ultimately, checking the fridge repeatedly is a quirky blend of instinct, habit, and hope. It reflects our brain’s wiring for reward, our evolutionary past, and the rhythms of modern life. So, the next time you catch yourself staring at the same yogurt container, smile—you’re just a human, chasing a spark of novelty in a familiar place.
