10 Common Cognitive Biases You Should Know (With Simple Examples)
What is Cognitive Bias? Cognitive bias is a systematic thinking error that happens when our brain tries to simplify how we process information. Because our brains receive huge amounts of information every day, we often rely on mental shortcuts to make quick decisions. These shortcuts are helpful, but they can also lead us to misjudge situations, ignore important facts, or make irrational decisions. Example of Cognitive Bias For example, imagine you see many posts on social media showing people becoming successful entrepreneurs or making huge profits from cryptocurrency. After seeing these stories repeatedly, you might start believing that becoming rich through business or crypto is very common. In reality, these stories often highlight the few successes, while many failures are rarely shared online. Your brain tends to remember the most striking stories, which can distort your perception of how common success really is. Why do you need to understand these biases? Cognitive biases affect many areas of life, including money decisions, career choices, relationships, and even how we judge other people. Understanding them can help us think more clearly and avoid common mental traps. Below are 10 common cognitive bias traps that influence how people think and make decisions. TLDR: Ten (10) common Cognitive Bias (认知偏差): 1. Survivorship Bias（幸存者偏差） 2. Sunk Cost Fallacy（沉没成本谬误） 3. Confirmation Bias（确认偏差） 4. Anchoring Effect（锚定效应） 5. Framing Effect（框架效应） 6. Availability Heuristic（可得性偏差） 7. Dunning–Kruger Effect（达克效应） 8. Belief in a Just World (BJW)（公正世界假设） 9. Bandwagon Effect（从众效应） 10. Self-Serving Bias（自利归因偏差） 1. Survivorship Bias Survivorship bias happens when we only look at the successful examples and ignore all the failures that disappeared. Because of this, we might think something is easier or more effective than it actually is. Example: You see many stories about successful startup founders like Elon Musk or Mark Zuckerberg, and think starting a company is a great path to success. But we rarely hear about the thousands of startups that failed. Looking only at survivors gives a misleading picture. 2. Sunk Cost Fallacy This happens when people continue doing something just because they have already invested time, money, or effort, even when it’s no longer a good decision. Example: You bought a movie ticket, but the movie is terrible after 20 minutes. Instead of leaving, you stay because you think: “I already paid for it.” But the money is already gone. Staying doesn’t bring it back. 3. Confirmation Bias People tend to seek out information that supports what they already believe and ignore information that contradicts it. Example: Someone believes that cryptocurrency is always a scam. They will: Read news about crypto fraud or crypto scam Share stories of people losing money But they might ignore positive developments or successful projects. 4. Anchoring Effect The first number or piece of information we see becomes an “anchor” that influences our later judgment. Example: A jacket is labeled: “Was $200 — Now $90” Even if $90 is still expensive, the $200 anchor makes the discount look more attractive. Retailers often use this trick in pricing. Advertising Billboard: 5. Framing Effect People make different decisions depending on how information is presented, even when the facts are the same. Example: Two ways to describe the same medical treatment: “This treatment has a 90% success rate.” “This treatment has a 10% failure rate.” Both statements describe the same outcome; most people feel more confident about the first one. This is an example of the Framing Effect. 6. Availability Heuristic People judge how common something is based on how easily examples come to mind. If we hear about something often, we think it happens a lot. Example: After seeing several news stories about plane crashes, someone might think flying is very dangerous. In reality, flying is much safer than driving, but dramatic events are easier to remember. 7. Dunning–Kruger Effect People with low knowledge or skill often overestimate their ability, because they don’t know enough to recognize their mistakes. Meanwhile, experts may underestimate themselves. Example: A beginner learns a little about investing and suddenly believes they can beat the market easily. But experienced investors know that investing is complex and risky. 8. Belief in a Just World (BJW) People want to believe that the world is fair, where good actions lead to rewards and bad actions lead to punishment. Because of this, people sometimes assume victims must have done something wrong. Example: When someone loses their job, others might say: “They must not have worked hard enough.” Even though layoffs often happen due to economic conditions, not merely personal failure. 9. Bandwagon Effect People tend to follow what many others are doing, simply because it appears popular. Example: A product on an e-commerce site shows: “10,000 people bought this item” Many customers will buy it too because they assume: “If everyone is buying it, it must be good.” This is why social proof is widely used in marketing. 10. Self-Serving Bias People tend to attribute success to their own ability, but blame failures on external factors. Example: If a student gets a good exam result, they might say: “I’m smart.” If they get a bad result, they might say: “The exam was unfair.” This bias helps protect self-esteem. Self-Serving Bias example in Malaysia – politics: In politics, self-serving bias can also appear in how politicians explain success and failure. For example, when policies succeed, political leaders may credit their own leadership or strategy. But when problems occur, they may blame opposing parties or external factors instead. In Malaysia, political debates sometimes include phrases like “ini semua salah DAP” (“this is all DAP’s fault”), where responsibility is shifted to another party rather than acknowledging internal mistakes. Blaming others can be an easier way to protect one’s reputation and gain political support.
Football (Soccer) Betting Terms Explained for Beginners Ahead of the 2026 FIFA World Cup
The 2026 FIFA World Cup is just around the corner (June 11–July 19), hosted jointly by the United States, Canada, and Mexico, with Argentina returning as the defending champions. Responsible Betting & Educational Disclaimer: This article is intended for educational and informational purposes only. It aims to explain common football (soccer) betting terms in a clear and beginner-friendly manner, particularly for readers new to sports betting or preparing to follow major tournaments, such as the 2026 FIFA World Cup. Football betting involves financial risk, and outcomes are never guaranteed. Readers should always bet responsibly and be aware of their local laws and age restrictions related to gambling. This content does not constitute betting advice, financial advice, or a recommendation to place any specific bet. All examples used are for explanation purposes only. The publisher may include advertisements, brand mentions, affiliate links, or backlinks to licensed, regulated, and reputable bookmakers or betting platforms for informational or commercial purposes. Readers are encouraged to conduct their own due diligence. Let’s Get Started Football (soccer) betting Football (soccer) betting involves predicting the outcome of a football match or specific events within a match and placing a wager on that prediction with a bookmaker. If your prediction is correct, you win based on the odds offered; if it’s wrong, you lose your stake. Example: You bet on England to win a World Cup match. If England wins, you earn a payout based on the odds; if they draw or lose, the bet loses. Most Popular Sports for Betting Football (soccer) is the most popular sport for betting worldwide due to its global fan base, frequent matches, and wide variety of betting markets. Other major sports betting events include basketball, horse racing, American football/ rugby, tennis, and cricket, each attracting bettors for different reasons such as fast-paced games, seasonal leagues, individual player matchups, or long-standing betting traditions. Horse Racing Who are bookmakers and their roles on football betting Bookmakers (or bookies) are companies or platforms that offer odds and accept bets on football matches and other sporting events. Their role is to set the odds for different outcomes, take bets from players, and pay out winnings when bets are successful. Example: A bookmaker offers odds for a World Cup match between Germany and Brazil—if you place a bet on Germany to win and the result is correct, the bookmaker pays you according to the listed odds; if not, the bookmaker keeps the stake. Common Football Betting Terms: Below are some of the most common football betting terms used by bookmakers on their platforms. Betting Terms Explained Odds (赔率): Odds show how much you can win from a bet and how likely an outcome is according to the bookmaker. Fixed odds mean the odds are locked in when you place your bet and will not change, even if the odds move later. Example: You place a bet at odds of 2.00 on a team to win. If you stake $10 and win, you receive $20 (your stake plus profit). Odds boost An odds boost is a promotion where the bookmaker temporarily increases the odds on a specific bet to offer a higher potential payout. Example: Odds boosted from 2.00 to 2.50 means a $10 winning bet would return $25 instead of $20. Odds Formats There are three main odds formats used in football betting: Fractional odds (commonly used in the UK): Show profit relative to stake (e.g., 5/1 means you win 5 for every 1 staked). Decimal odds (used in Europe and most of the world): Show total return including stake (e.g., 2.00 returns 2× your stake). and American odds (also known as moneyline odds). Show how much you need to bet to win 100, or how much you win from 100. For instance: 2/1 = 3.0 = +200 They all represent the same betting value, just written differently depending on the region or bookmaker. 2/1 (Fractional odds – UK):You win 2 units for every 1 unit you bet.Example: Bet $10 → win $20 profit (+ your $10 stake back). 3.0 (Decimal odds – Europe / global):Your total return is 3× your stake.Example: Bet $10 → get $30 total ($20 profit + $10 stake). +200 (American odds / Moneyline):You win $200 for every $100 bet.Example: Bet $100 → win $200 profit (+ your $100 stake). 👉 Key takeaway:Different formats, same odds, same payout, just shown in different styles. Stake (投注金额): Stake is the amount of money you place on a bet. Example: If your stake is $10 and the odds are 2.00, a winning bet returns $20 in total ($10 profit plus your $10 stake). If your stake is $10 and the odds are 3.00, a winning bet returns $30 in total ($20 profit plus your $10 stake). Rake (平台抽成): Rake is the commission or fee that a bookmaker (or betting platform) takes from bets, which is built into the odds or deducted from winnings in certain markets. It’s how bookmakers make money regardless of the match outcome. Example: If the true fair odds should be 2.00 but the bookmaker offers 1.90, the difference represents the rake built into the odds. Simple Example: Stake (投注金额): $10 True fair odds: 2.00 Bookmaker odds: 1.90 If the odds were 2.00, a winning bet would return $20 ($10 profit + $10 stake). But because the bookmaker offers 1.90, a winning bet returns $19 instead. 👉 The $1 difference represents the bookmaker’s rake (抽水), which is their commission built into the odds. Bookmakers don’t usually charge a fee directly—instead, they lower the odds slightly, and that difference is how they make money. Payout: Payout is the total amount of money you receive if your bet wins, including your original stake and any profit. Example: If your stake is $10 and the odds are 2.50, your payout is $25 ($15 profit + your $10 stake). 1X2 (Match Result Betting): 1X2 is the most basic and popular football betting market, where you bet on the final result of a match after 90 minutes
30 High-Value Trade Skills & Trade Jobs Explained
What Are Trade Skills and Trade Jobs? Trade skills are practical, hands-on abilities used to solve real-world problems, things like building, fixing, installing, and maintaining essential systems that people rely on every day. Unlike many office jobs, most trade jobs do not require a four-year university degree. Instead, they are typically learned through apprenticeships, on-the-job training, vocational programs, and industry certifications or union licensing, which can take 3–5 years. “You are earning while learning.” This path allows people to enter the workforce without student debt. With certain years of experience, some of these trade skills and trade jobs can earn a high, stable income, and in some cases, significant long-term wealth. Disclaimer: I’m not currently working in a trade profession myself, though I might seriously consider it one day if I ever grow tired of office work. I may also have accidentally left out some trade jobs, and the list below is not in any particular order or hierarchy. I have genuine respect for all skilled trades and manual professions. These are people who create real value, solve real-world problems, and keep the economy functioning every day. 1. Electrical | Electrician An electrician is a skilled tradesperson who installs, maintains, and repairs electrical systems that power homes, buildings, factories, and infrastructure. This includes wiring, circuit breakers, lighting systems, power distribution, and safety controls. Electricians typically learn their trade through apprenticeships, on-the-job training, and licensing, rather than a four-year university degree. Many electricians go beyond basic residential work by specializing in higher-value areas. As aging infrastructure needs upgrades, skilled electricians are in strong demand to modernize old wiring and electrical systems. Others focus on green and renewable energy, such as solar panel systems, energy storage, and smart grids. With the rise of electric vehicles, EV charger installation has also become a fast-growing and well-paid specialty. After completing training and exams, a journeyman electrician can work independently, and those who move into commercial or industrial projects — such as factories, data centers, and large buildings — often earn premium rates compared to residential-only work. 2. Plumber A plumber installs, repairs, and maintains water supply, drainage, and gas systems in homes, commercial buildings, and industrial facilities. Their work includes pipes, fixtures, water heaters, sewage systems, and leak detection, essential services that people and businesses depend on every day. Like other trade jobs, plumbing is learned through apprenticeships, hands-on training, and licensing, not a university degree. Plumbers can specialize in residential, commercial, or industrial work, with commercial and industrial projects often paying higher rates due to complexity and scale. There is also strong demand for emergency plumbing, aging pipe replacement, and water-efficiency upgrades. Because plumbing problems cannot be delayed or outsourced, skilled plumbers enjoy steady demand, job security, and solid earning potential. 3. HVAC Technician An HVAC technician installs, maintains, and repairs heating, ventilation, and air conditioning systems that keep homes, offices, hospitals, and factories comfortable and safe. This trade is typically learned through apprenticeships, technical training, certifications, and licensing, rather than a four-year degree. HVAC work goes beyond residential air-conditioners. Technicians who handle commercial and industrial systems, energy-efficient upgrades, smart climate controls, or heat pumps and green cooling systems often earn higher pay due to system complexity. Because climate control is essential—and systems need constant maintenance—HVAC technicians benefit from year-round demand and strong income stability. 4. Welder (Including Specialized Welders) A welder joins, cuts, and repairs metal parts used in construction, manufacturing, energy, and infrastructure projects. Welding is a hands-on trade learned through vocational training, apprenticeships, and certifications, not a university degree. Welders work with steel, aluminum, and other metals to build everything from buildings and bridges to pipelines and heavy machinery. Some welders move into highly specialized and higher-paying fields. Pipeline welders work on oil, gas, and utility lines, often in remote locations with premium pay. Structural steel welders handle large-scale construction such as skyscrapers and bridges. At the extreme end, underwater welders combine commercial diving with welding skills for offshore and marine projects. These specialized roles are physically demanding but can offer exceptionally high income due to risk, skill level, and the shortage of qualified workers. 5. Heavy Equipment / Industrial Equipment Operator A heavy or industrial equipment operator runs large machinery used in construction, mining, manufacturing, and infrastructure projects. This includes excavators, bulldozers, cranes, forklifts, and other specialized machines. Operators who handle large-scale or high-risk machinery, such as cranes, port equipment, or industrial production systems, often earn higher wages due to the skill, precision, and safety responsibility involved. These roles are critical for building roads, factories, ports, and energy projects, making them high-demand, well-paid trade jobs that cannot be easily automated or outsourced. 6. Elevator / Escalator Technician An elevator and escalator technician installs, maintains, and repairs vertical transportation systems used in high-rise buildings, malls, hospitals, airports, and transit hubs. This trade combines mechanical, electrical, and electronic skills, and is typically learned through apprenticeships, strict licensing, and manufacturer certifications, not a university degree. Because elevators and escalators are safety-critical systems, technicians are highly regulated and in limited supply. Those working on commercial buildings, high-rise towers, and transit systems often earn premium wages, especially with experience or union membership. As cities grow taller and infrastructure ages, this trade remains one of the most stable and lucrative paying skilled trades available without a degree. 7. Power Line Technician / Electric Lineworker (Lineman) A power line technician, also known as an electric lineworker or lineman, is responsible for installing, maintaining, and repairing high-voltage power lines that deliver electricity from the grid to cities, industries, and homes. This role is different from an electrician; lineworkers operate outside, often at great heights, working on poles, towers, and substations. This is one of the highest-paying trade jobs because the work is dangerous, physically demanding, and critical to public infrastructure. Lineworkers are essential during storms, blackouts, and emergencies, and many earn premium pay through overtime, hazard pay, and union agreements. With aging power grids, renewable energy expansion, and rising electricity demand, power line technicians remain highly respected, in-demand, and well-compensated skilled trades.
Empower Yourself: Self-Defense and Security Tips for Women
Foreword: Recent Tragedies That Shocked Malaysia Recent tragedies in Malaysia (2025) — from the bullying-related death of 13-year-old Zara at a religious boarding school in Sabah, to the gang rape of a Form Three girl by four older students at a government school in Alor Gajah, Melaka, and the fatal stabbing of a 16-year-old student by her 14-year-old schoolmate in Bandar Utama, Petaling Jaya — remind us that violence can strike anywhere, even within the walls of our schools. As I read about these cases, I felt deeply saddened and angry; Saddened for the innocent lives lost, and angry that such brutality could happen to young girls in places meant to keep them safe. Each victim was a daughter, a student, and a friend who deserved protection and care. These horrifying incidents highlight the urgent need for self-defence awareness, personal security education, and stronger protection systems for women and students across Malaysia. Self-defense & security tips In this article, I’ll be sharing some security tips, safety tools, and equipment, along with additional insights from my experience as a former Auxiliary Police Officer. This could be handy in dangerous situations, especially for those who are physically smaller or less able to defend themselves. 1. Pick up and practice a fighting skill, self-defence tactic Pick up a fighting skill or practical self-defence tactic Image Source: istockphoto Generally, women tend to be physically weaker than men in strength, size, and aggression. The goal of learning practical fighting or combat skills is to close that gap and — just as important — to be mentally prepared to respond or retaliate under stress. There’s a clear difference between someone who has trained in combat skills and someone who hasn’t. Practical fighting/ combat skills: Here are 5 practical fighting styles/self-defence combat skills: (Recommended by ChatGPT, you can use a similar prompt: “Suggest me 5 practical fighting and combat skills for women“) Muay Thai — Excellent for powerful, practical striking (elbows, knees, clinch) and building confidence. Kickboxing — Great for striking, footwork and conditioning; easy to learn basics fast. Judo — Focuses on throws, balance breaks and safe takedown/escape techniques (useful if attackers grab you). Brazilian Jiu-Jitsu (BJJ) — Teaches ground control and escapes — crucial if a fight goes to the ground. Krav Maga — Reality-based self-defence with simple, aggressive techniques and situational training for real attacks. Quick tip: Striking arts (Muay Thai, Kickboxing) are best if you want stand-up power and quick disabling strikes. Grappling arts (Judo, BJJ) are vital if you might be grabbed or taken to the ground. Krav Maga blends both with an emphasis on fast, practical escapes. 2. Use Pepper spray/ chili spray Pepper spray/ chili spray HK Police Officer with Pepper Spray Image source: Police.gov.hk Pepper spray/ chilli spray — a compact aerosol canister that ejects capsaicin-based irritant to temporarily disable an attacker by causing intense eye pain, tearing, coughing, and breathing difficulty. It’s designed to create a window to escape, not to injure permanently. Quick usage & safety tips: Aim for the attacker’s face/eyes, then run to safety — don’t try to “fight” after spraying. Keep it accessible (bag pocket, belt holster) and practice unlocking/deploying the canister so you can use it quickly. Check expiry dates and test sprays per manufacturer instructions; store away from heat. After use, call police and seek help — spraying can lead to legal or medical follow-up. Legal note (Malaysia): Pepper spray is regulated — many civilians carry small canisters for self-defence, but import/sale can require permits, and misuse can lead to criminal charges. Buy from reputable local sellers and keep proof of purchase; don’t bring it on flights. AOJP framework: As a former Auxiliary Police Officer, here are guidelines officers use to assess whether the use of force — including discharge of a firearm — is justifiable under the AOJP framework: Ability: Does the suspect have the physical means or weapon to cause the threatened harm? Opportunity: Is the suspect close enough and positioned to carry out the threat right now? Jeopardy: Is there an immediate risk of serious injury or death? Preclusion: Have all reasonable, less-lethal options been tried or ruled out? (This principle mainly applies to law enforcement officers who are equipped with both lethal weapons, such as firearms, and non-lethal options, such as tasers.) Spray or not, (likewise shoot or not shoot scenario). When deciding whether to use pepper spray, assess whether the situation satisfies the AOJ tests: the suspect’s Ability to cause harm, their Opportunity to carry out the harm, and the Jeopardy (immediacy/severity of the threat). The use of pepper spray is justifiable when the AOJ is met. 3. Use Emergency Personal Alarm/ Portable Safety Alarm Emergency Personal Alarm/ Portable Safety Alarm Wide range of personal safety alarm Back in the old days, people used whistles in distress situations to call for help, especially at night. Today, there are many emergency personal alarms or personal safety alarms that serve the same purpose — using a high-frequency, loud sound to attract attention, call for help, and frighten the assailant. These devices are usually battery-powered or rechargeable, and should be loud enough to startle the attacker and immediately alert people nearby to assist you. Electronic distraction device Just for sharing a new security product I’ve recently found: The Nextorch ND30 is a compact, non-pyrotechnic electronic distraction device (a civilian “electronic flash-bang” alternative) that combines an ultra-bright strobe and a very loud siren to temporarily disorient a threat and attract attention; it’s USB-rechargeable, ruggedly built, and designed to create a short window for escape — but check local laws before buying or carrying one. https://www.youtube.com/watch?v=NTN6w67EQ0M 4. Use your surrounding equipment as a self-defense weapon Surrounding equipment as self-defense tools Use items around you as improvised self-defence tools — for example, an umbrella, a high-heeled shoe, a heavy torch, a steering lock in your car, a wrench or spanner, or even a plastic/foldable chair. Use these everyday objects to create an opportunity to escape; ensure your response is proportionate and lawful. Seondary
