We often hear success stories from people who do something risky like business and learn new things. This inspires us to do the same thing as the characters in the story. However, we forget that many people have done the same thing as this character but failed and we may be part of those people who failed. This is called survivorship bias. Survivorship bias is a logical error that occurs when someone focuses on those who succeed while ignoring those who fail. This bias can lead to inaccurate assessments or analyses because it need to take into account information from those who failed. During World War II, British statistician Abraham Wald was tasked with analyzing damage to aircraft returning from missions to strengthen protection. Returning planes showed damage in certain areas, and many argued for reinforcing these damaged areas. However, Wald realized that the analysis ignored non-returning planes, which may have been damaged in areas not visible on the returning planes. So, he sug...

In the digital age, technology professionals have an increasingly significant impact on the environment. Application developers, technology companies, and data workers can create systems that promote energy efficiency, reduce paper use, and support remote work, which reduces transportation emissions. Furthermore, the digital industry also generates significant energy consumption through data centers and electronic devices, making it a responsibility for technology workers to create more environmentally friendly solutions. The Role of Healthcare Workers Doctors, nurses, and other healthcare workers see firsthand the impact of environmental damage on human health. Air pollution can increase the risk of respiratory diseases, water pollution triggers various infections, and climate change increases the risk of disasters and health crises. Therefore, healthcare workers play a vital role not only in treating patients but also in educating the public about the relationship between the environ...

Ketika melakukan promosi di media sosial, ada beberapa hal yang tidak boleh dilakukan karena bisa merusak reputasi brand, menurunkan kepercayaan audiens, atau bahkan melanggar kebijakan platform. Oleh karena itu, penting untuk mengetahui apa saja yang tidak boleh dilakukan saat promosi di media sosial agar upaya pemasaran Anda memberikan hasil yang maksimal. Berikut adalah hal-hal yang jagan dilakukan ketika promisi di media sosial: 1. Overposting Salah satu kesalahan umum adalah membanjiri audiens dengan postingan promosi setiap hari. Media sosial bukan hanya tempat untuk menjual, tapi juga untuk membangun hubungan dengan pelanggan. Jika isi konten hanya ajakan membeli tanpa ada nilai lain, audiens akan merasa terganggu dan perlahan meninggalkan akun Anda. Cobalah untuk menyeimbangkan konten promosi dengan informasi, hiburan, atau edukasi yang relevan dengan target pasar Anda. 2. Membeli Audience Palsu Godaan untuk terlihat populer bisa membuat beberapa brand tergoda membeli followers...

Ginger has long been known as a spice, cooking spice, and beverage. As a beverage, ginger is believed to have various health benefits. Here are the health benefits of ginger: 1.

PTSD (Post-Traumatic Stress Disorder) is a mental health condition that can occur after someone experiences or witnesses a traumatic event that threatens their life or physical integrity. PTSD can affect people of all ages and backgrounds and can develop after experiencing events such as war, sexual violence, serious accidents, or natural disasters. There are 4 main categories of PTSD symptoms, namely re-experiencing the bad experience as if we were experiencing it again in our minds, avoiding situations, places, conversations, people and other things related to the traumatic event, hyperarousal, and negative changes in mood and cognition. These symptoms can appear several months or years after the incident. To receive a diagnosis of PTSD, the symptoms must last for more than one month and significantly interfere with a person's daily life. Groups of people who are vulnerable to experiencing PTSD are war victims, military members, health workers and journalists. The reason this gro...

직장에서 불안감을 느끼는 것은 흔히 약점으로 여겨집니다. 하지만 경쟁이 치열하고 급변하며 타인과 비교가 빈번한 직장 현실에서, 이러한 감정은 사실 매우 인간적인 것입니다. 신입 사원부터 경험 많은 전문가, 리더에 이르기까지 거의 모든 사람이 이를 경험합니다. 중요한 것은 이 불안감에 어떻게 대응하느냐입니다. 이를 없애려고 애쓰기보다는, 제대로 이해하고 적절히 관리하는 것이 더 나은 접근 방식입니다. 다음은 이에 대처하는 방법입니다. 1. 불안감의 원인을 파악하라 첫 번째 단계는 불안감이 어디서 비롯되는지 파악하는 것입니다. 경험 부족 때문인가, 동료들과의 역량 차이 때문인가, 긍정적인 피드백이 부족하기 때문인가, 아니면 지원이 부족한 업무 환경 때문인가? 역량 격차에서 비롯된 불안감은 유해한 직장 문화에서 비롯된 불안감과는 다른 해결책이 필요합니다. 원인을 파악하지 못하면 잘못된 조치를 취할 위험이 있습니다. 2. 사실과 가정을 구분하기 많은 불안감은 객관적인 사실이 아니라 머릿속의 부정적인 생각에서 비롯됩니다. “나는 여기에 어울리지 않아”와 같은 생각은 대개 구체적인 증거로 뒷받침되지 않습니다. 실제로 사람들은 특정 자격 요건을 충족하기 때문에 채용됩니다. “이건 사실인가, 아니면 단지 가정인가?”라고 자문하는 습관을 들이면, 자신감을 갉아먹는 과도한 고민의 악순환을 끊는 데 도움이 될 수 있습니다. 3. 건강하지 않은 비교는 피하세요 직장에서는 다른 사람들이 보는 것은 대개 훌륭한 아이디어나 주목받는 성과와 같은 결과물뿐입니다. 그들이 겪은 긴 과정, 실패, 그리고 압박감은 거의 드러나지 않습니다. 자신의 모습을 타인의 빛나는 성과와 비교하는 것은 부족함을 더욱 심화시킬 뿐입니다. 더 건강한 비교 방법은 시간이 지남에 따라 자신의 성장 과정을 돌아보는 것입니다. 4. 불안감을 자기 계발의 동기로 전환하세요 불안감은 본질적으로 하나의 신호입니다. 특정 분야에서 열등감을 느낀다면, 이는 아직 발전할 여지가 있는 분야임을 의미합니다. 전문 능력에 대한 불안감은...

La mayoría de la gente piensa que la investigación espacial solo tiene que ver con cohetes, satélites o la exploración de otros planetas. Sin embargo, muchas de las tecnologías que utilizamos en nuestra vida cotidiana surgieron de las necesidades de la exploración espacial. Para sobrevivir en entornos extremos, los científicos deben crear nuevas tecnologías que luego se desarrollan y se utilizan ampliamente en la Tierra. A continuación, te presentamos algunas tecnologías que surgieron de la investigación espacial. 1. Tecnología de satélites y navegación Uno de los mayores logros de la investigación espacial es la tecnología de satélites. Los sistemas de navegación como el GPS tienen su origen en el desarrollo de la tecnología de satélites para fines militares y la exploración espacial. Hoy en día, esta tecnología se utiliza en el transporte, los servicios de reparto, la cartografía digital e incluso en aplicaciones para teléfonos inteligentes. 2. Materiales resistentes al calor La inve...

If you look at a world map, you will find that many of the largest cities are situated by the sea or not far from the coastline. Cities such as London, Singapore, Tokyo, Shanghai, New York, and Jakarta developed in areas with access to the sea. This phenomenon is no coincidence. For thousands of years, coastal areas have been the most strategic locations for establishing centers of trade, government, and civilization. So, why do major cities tend to grow along the coast? 1. The Sea Was the First Transportation Route Before the advent of highways, railways, and airplanes, the sea was the most efficient transportation route for moving both people and goods. Ships could carry far heavier loads than the land-based transport of that era. Consequently, areas with ports evolved into hubs where traders, residents, and economic activities converged, eventually expanding into cities. 2. Easier Access to Global Trade Coastal cities enjoy an advantage due to their direct connectivity to other regi...

Agroforestry is a land management system that combines forestry crops with agriculture or livestock farming in one area. This approach is seen as an alternative to monoculture systems that tend to deplete the land's ecological functions. In practice, agroforestry offers various benefits, but also poses significant challenges. Advantages of Agroforestry 1. Diversification of Income Sources Agroforestry allows farmers to obtain income from various commodities such as food crops, fruits, timber, and non-timber forest products. This diversification reduces dependence on a single commodity and increases the economic resilience of farming households during market price fluctuations. 2. Improving Soil and Water Quality The presence of trees plays a role in preventing erosion, increasing organic matter content, and improving soil structure. Diverse root systems also help increase water absorption and reduce surface runoff. 3. Enhancing Biodiversity The combination of plants across differen...
