Hidden influence of self-imposed rules on human behaviour
Breaking boundaries:
Self-imposed rules subtly govern many aspects of human behaviour, often without conscious awareness of their influence. These unwritten constraints, shaped by cultural traditions, social norms, and personal biases, offer a sense of order but can simultaneously hinder flexibility, creativity, and rational decision-making. While some rules serve vital functions, such as ensuring safety or hygiene, many persist due to fear, misinformation, or a lack of empirical evidence. By understanding the psychological and cultural origins of these limitations, individuals can make more informed choices, alleviating unnecessary anxieties and enhancing personal freedom. Rigid adherence to these rules—driven by cognitive rigidity, perfectionism, or cultural conditioning—can increase stress and obstruct adaptability. Embracing flexibility and questioning these constraints invites new experiences and growth, fostering a more empowering mindset. Instead of focusing on the question “Can this be done?” individuals should ask, “Why not?” Achieving a balance between tradition and rationality allows behaviours to serve personal well-being, resilience, and progress in society.
Cultural Differences in Dining Etiquette: A Reflection on Personal Experiences
During my visit to Chengdu, a beautiful city in China, last November, I was accompanied by a friend who was well-versed in the local customs. One afternoon, while having lunch with a group of friends, I instinctively attempted to manage some food with my fingers. To my surprise, my Chinese friends reacted with visible discomfort and disapproval. They were adept at using chopsticks, skillfully handling complex food items such as grilled meat and bony fish. However, I struggled with chopsticks, lacking the dexterity to manage intricate dishes effectively. The reaction of my Chinese companions underscored the strong cultural emphasis on proper utensil use in China. In Chinese culture, using chopsticks is not only a matter of practicality but also a sign of etiquette and respect. Eating with fingers, unless explicitly part of a particular regional cuisine, is generally perceived as unhygienic or inappropriate in formal settings.
A similar experience occurred in Sri Lanka while I was working for a bank. At a formal dinner, in a well-known restaurant in Colombo, a few colleagues and I opted to eat with our fingers, a common practice in Sri Lankan culture, particularly for rice-based dishes. However, the General Manager expressed his disapproval, making disparaging remarks and insisting that we use a fork and spoon instead. This reaction reflected the influence of Western dining etiquette in professional and formal settings in Sri Lanka. British colonial rule significantly impacted Sri Lankan dining customs, leading to the adoption of Western-style utensils in formal and corporate environments. Despite the cultural acceptability of eating with fingers in many local households, there is an increasing preference for Western table manners in urban and elite circles.
These experiences highlight the intersection of cultural expectations and globalization. In many Asian cultures, including India, Sri Lanka, and parts of the Middle East, eating with hands is a long-standing tradition associated with sensory engagement and respect for food. Conversely, in East Asian countries, such as China, Japan, and Korea, chopsticks are the primary utensils, and using hands is generally frowned upon. Western dining etiquette, emphasizing cutlery, such as forks, knives, and spoons, has gained prominence globally, often being regarded as a standard for formal dining.
Breaking Self-Imposed Rules: Challenging Cultural and Social Norms
Humans often create and adhere to self-imposed rules that shape their behaviours, beliefs, and everyday practices. These rules, though not legally or universally mandated, become ingrained in certain communities or cultures to the point that breaking them appears unnatural or even unacceptable. Many of these unwritten rules stem from cultural traditions, social norms, or personal biases rather than rational thought. While these informal restrictions offer structure and continuity, they can also limit flexibility, innovation, and personal freedom.
Cultural and Social Norms in Food Choices
One area where self-imposed rules are evident is in food consumption. Cultural norms strongly influence what people eat, how they prepare their food, and what combinations are deemed acceptable. The example of eating kiribath (milk rice) with katta sambol (a kind of chili paste) and fried eggs illustrates this concept. The surprised reaction from a colleague—”Can you eat kiribath with eggs?”—suggests an implicit rule about what ingredients pair well together. However, food combinations are subjective and often vary by personal taste and cultural background.
Another example is the reaction to drinking coffee mixed with a popular chocolate-malt powder due to the unavailability of regular milk powder. A friend’s response, “Bonna puluvanda?” (Can you drink it?). This reveals an assumption that certain beverage combinations are unacceptable. However, blending coffee with other drinks is common in different cultures—consider mocha, which combines coffee and chocolate, or Thai iced coffee, which includes sweetened condensed milk. These examples demonstrate that many food-related self-imposed rules are based on familiarity rather than objective reasoning.
Rationality and Irrationality in Everyday Fears and Perceptions
Human perceptions of safety, hygiene, and risk often stem from personal experiences, cultural influences, and cognitive biases. While some concerns have a rational basis, others may be exaggerated due to fear, misinformation, or lack of direct experience.
Perceived Risks of Three-Wheelers: Rational or Irrational?
Three-wheelers, commonly used in regions like South Asia, Africa, and parts of Latin America, are often perceived as risky due to factors such as driver anonymity, lack of physical protection, and exposure to external elements like dust and germs. However, countries like India and Sri Lanka have implemented regulations, including registered driver identification and GPS tracking, to enhance passenger security. While three-wheelers offer less structural protection in accidents compared to cars, their safety largely depends on road conditions, driver behaviour, and adherence to traffic laws. In well-regulated environments, with modern security measures, the risks associated with three-wheelers are significantly minimal. making them a relatively safe transport option.
Exposure to Germs and External Elements
Some individuals avoid three-wheelers due to concerns that wind exposure may carry germs or pollutants. While air pollution is a legitimate health issue, particularly in urban areas, it is not exclusive to three-wheelers. Walking, cycling, or even using open windows in a car can lead to similar exposure. Generally, outdoor exposure to pollutants is often less harmful than indoor air pollution in poorly ventilated vehicles. This suggests that while external exposure exists, it may not be as harmful as perceived.
Food-Related Phobias and Hygiene Concerns
Similarly, some people refuse to eat certain foods due to fear of contamination or improper hygiene practices. This phenomenon can be categorized as food neophobia (fear of new foods) or contamination phobia, both of which are influenced by psychological and cultural factors.
Fear of Contamination and Hygiene Standards
Concerns about food hygiene are rational when considering the risks of foodborne illnesses, which can result from improper handling, washing, or cooking. The World Health Organization emphasizes that food safety practices, such as washing vegetables and proper storage, are essential to prevent bacterial infections. However, excessive fear, especially when there is no evidence of contamination, may indicate an irrational phobia rather than a legitimate health concern.
The Impact of Rigid Beliefs on Daily Life and Psychological Well-being
Human behaviour is shaped by a complex interplay of cultural, psychological, and personal factors. Some individuals adhere strictly to self-imposed rules, often making their lives unnecessarily difficult. Consider a scenario where a son refuses to sit on a chair recently occupied by his mother or insists on washing rice multiple times in pursuit of perfectly clear water. These actions, while seemingly trivial, reflect a deeper psychological and cultural conditioning that influences behaviour and decision-making.
Sociocultural Influences on Behavioural Rigidity
Cultural traditions and upbringing play a crucial role in shaping rigid behaviours. For instance, in some Asian societies, the concept of ritual purity dictates that certain objects or spaces become temporarily “unclean” after being used by someone else.
The Consequences of Inflexibility
People who set rigid rules for themselves often face unnecessary stress and limitations. Research has shown that cognitive inflexibility is associated with higher levels of anxiety, stress, and dissatisfaction with life. By adhering to self-imposed rules that lack a logical basis, individuals reduce their ability to adapt to new situations and experience life more freely.
The Importance of Flexibility and Adaptability
Developing psychological flexibility allows individuals to adjust their behaviour according to different contexts, making life more manageable and enjoyable. Psychological flexibility has been linked to better mental health, improved problem-solving skills, and greater resilience. Learning to let go of unnecessary rules and adapting to situations can lead to a more fulfilling life.

Ranking public services with AI — A roadmap to reviving institutions like SriLankan Airlines
Efficacy measures an organisation’s capacity to achieve its mission and intended outcomes under planned or optimal conditions. It differs from efficiency, which focuses on achieving objectives with minimal resources, and effectiveness, which evaluates results in real-world conditions. Today, modern AI tools, using publicly available data, enable objective assessment of the efficacy of Sri Lanka’s government institutions.
Among key public bodies, the Supreme Court of Sri Lanka emerges as the most efficacious, outperforming the Department of Inland Revenue, Sri Lanka Customs, the Election Commission, and Parliament. In the financial and regulatory sector, the Central Bank of Sri Lanka (CBSL) ranks highest, ahead of the Securities and Exchange Commission, the Public Utilities Commission, the Telecommunications Regulatory Commission, the Insurance Regulatory Commission, and the Sri Lanka Standards Institution.
Among state-owned enterprises, the Sri Lanka Ports Authority (SLPA) leads in efficacy, followed by Bank of Ceylon and People’s Bank. Other institutions assessed included the State Pharmaceuticals Corporation, the National Water Supply and Drainage Board, the Ceylon Electricity Board, the Ceylon Petroleum Corporation, and the Sri Lanka Transport Board. At the lower end of the spectrum were Lanka Sathosa and Sri Lankan Airlines, highlighting a critical challenge for the national economy.
Sri Lankan Airlines, consistently ranked at the bottom, has long been a financial drain. Despite successive governments’ reform attempts, sustainable solutions remain elusive.
Globally, the most profitable airlines operate as highly integrated, technology-enabled ecosystems rather than as fragmented departments. Operations, finance, fleet management, route planning, engineering, marketing, and customer service are closely coordinated, sharing real-time data to maximise efficiency, safety, and profitability.
The challenge for Sri Lankan Airlines is structural. Its operations are fragmented, overly hierarchical, and poorly aligned. Simply replacing the CEO or senior leadership will not address these deep-seated weaknesses. What the airline needs is a cohesive, integrated organisational ecosystem that leverages technology for cross-functional planning and real-time decision-making.
The government must urgently consider restructuring Sri Lankan Airlines to encourage:
=Joint planning across operational divisions
=Data-driven, evidence-based decision-making
=Continuous cross-functional consultation
=Collaborative strategic decisions on route rationalisation, fleet renewal, partnerships, and cost management, rather than exclusive top-down mandates
Sustainable reform requires systemic change. Without modernised organisational structures, stronger accountability, and aligned incentives across divisions, financial recovery will remain out of reach. An integrated, performance-oriented model offers the most realistic path to operational efficiency and long-term viability.
Reforming loss-making institutions like Sri Lankan Airlines is not merely a matter of leadership change — it is a structural overhaul essential to ensuring these entities contribute productively to the national economy rather than remain perpetual burdens.

Why Pi Day?
International Day of Mathematics falls tomorrow
The approximate value of Pi (π) is 3.14 in mathematics. Therefore, the day 14 March is celebrated as the Pi Day. In 2019, UNESCO proclaimed 14 March as the International Day of Mathematics.
Ancient Babylonians and Egyptians figured out that the circumference of a circle is slightly more than three times its diameter. But they could not come up with an exact value for this ratio although they knew that it is a constant. This constant was later named as π which is a letter in the Greek alphabet.
It was the Greek mathematician Archimedes (250 BC) who was able to find an upper bound and a lower bound for this constant. He drew a circle of diameter one unit and drew hexagons inside and outside the circle such that the sides of each hexagon touch the sides of the circle. In mathematics the circle passing through all vertices of a polygon is called a ‘circumcircle’ and the largest circle that fits inside a polygon tangent to all its sides is called an ‘incircle’. The total length of the smaller hexagon then becomes the lower bound of π and the length of the hexagon outside the circle is the upper bound. He realised that by increasing the number of sides of the polygon can make the bounds get closer to the value of Pi and increased the number of sides to 12,24,48 and 60. He argued that by increasing the number of sides will ultimately result in obtaining the original circle, thereby laying the foundation for the theory of limits. He ended up with the lower bound as 22/7 and the upper bound 223/71. He could not continue his research as his hometown Syracuse was invaded by Romans and was killed by one of the soldiers. His last words were ‘do not disturb my circles’, perhaps a reference to his continuing efforts to find the value of π to a greater accuracy.
Archimedes can be considered as the father of geometry. His contributions revolutionised geometry and his methods anticipated integral calculus. He invented the pulley and the hydraulic screw for drawing water from a well. He also discovered the law of hydrostatics. He formulated the law of levers which states that a smaller weight placed farther from a pivot can balance a much heavier weight closer to it. He famously said “Give me a lever long enough and a place to stand and I will move the earth”.
Mathematicians have found many expressions for π as a sum of infinite series that converge to its value. One such famous series is the Leibniz Series found in 1674 by the German mathematician Gottfried Leibniz, which is given below.
π = 4 ( 1 – 1/3 + 1/5 – 1/7 + 1/9 – ………….)
The Indian mathematical genius Ramanujan came up with a magnificent formula in 1910. The short form of the formula is as follows.
π = 9801/(1103 √8)
For practical applications an approximation is sufficient. Even NASA uses only the approximation 3.141592653589793 for its interplanetary navigation calculations.
It is not just an interesting and curious number. It is used for calculations in navigation, encryption, space exploration, video game development and even in medicine. As π is fundamental to spherical geometry, it is at the heart of positioning systems in GPS navigations. It also contributes significantly to cybersecurity. As it is an irrational number it is an excellent foundation for generating randomness required in encryption and securing communications. In the medical field, it helps to calculate blood flow rates and pressure differentials. In diagnostic tools such as CT scans and MRI, pi is an important component in mathematical algorithms and signal processing techniques.
This elegant, never-ending number demonstrates how mathematics transforms into practical applications that shape our world. The possibilities of what it can do are infinite as the number itself. It has become a symbol of beauty and complexity in mathematics. “It matters little who first arrives at an idea, rather what is significant is how far that idea can go.” said Sophie Germain.
Mathematics fans are intrigued by this irrational number and attempt to calculate it as far as they can. In March 2022, Emma Haruka Iwao of Japan calculated it to 100 trillion decimal places in Google Cloud. It had taken 157 days. The Guinness World Record for reciting the number from memory is held by Rajveer Meena of India for 70000 decimal places over 10 hours.
Happy Pi Day!

Sheer rise of Realpolitik making the world see the brink
The recent humanly costly torpedoing of an Iranian naval vessel in Sri Lanka’s Exclusive Economic Zone by a US submarine has raised a number of issues of great importance to international political discourse and law that call for elucidation. It is best that enlightened commentary is brought to bear in such discussions because at present misleading and uninformed speculation on questions arising from the incident are being aired by particularly jingoistic politicians of Sri Lanka’s South which could prove deleterious.
As matters stand, there seems to be no credible evidence that the Indian state was aware of the impending torpedoing of the Iranian vessel but these acerbic-tongued politicians of Sri Lanka’s South would have the local public believe that the tragedy was triggered with India’s connivance. Likewise, India is accused of ‘embroiling’ Sri Lanka in the incident on account of seemingly having prior knowledge of it and not warning Sri Lanka about the impending disaster.
It is plain that a process is once again afoot to raise anti-India hysteria in Sri Lanka. An obligation is cast on the Sri Lankan government to ensure that incendiary speculation of the above kind is defeated and India-Sri Lanka relations are prevented from being in any way harmed. Proactive measures are needed by the Sri Lankan government and well meaning quarters to ensure that public discourse in such matters have a factual and rational basis. ‘Knowledge gaps’ could prove hazardous.
Meanwhile, there could be no doubt that Sri Lanka’s sovereignty was violated by the US because the sinking of the Iranian vessel took place in Sri Lanka’s Exclusive Economic Zone. While there is no international decrying of the incident, and this is to be regretted, Sri Lanka’s helplessness and small player status would enable the US to ‘get away with it’.
Could anything be done by the international community to hold the US to account over the act of lawlessness in question? None is the answer at present. This is because in the current ‘Global Disorder’ major powers could commit the gravest international irregularities with impunity. As the threadbare cliché declares, ‘Might is Right’….. or so it seems.
Unfortunately, the UN could only merely verbally denounce any violations of International Law by the world’s foremost powers. It cannot use countervailing force against violators of the law, for example, on account of the divided nature of the UN Security Council, whose permanent members have shown incapability of seeing eye-to-eye on grave matters relating to International Law and order over the decades.
The foregoing considerations could force the conclusion on uncritical sections that Political Realism or Realpolitik has won out in the end. A basic premise of the school of thought known as Political Realism is that power or force wielded by states and international actors determine the shape, direction and substance of international relations. This school stands in marked contrast to political idealists who essentially proclaim that moral norms and values determine the nature of local and international politics.
While, British political scientist Thomas Hobbes, for instance, was a proponent of Political Realism, political idealism has its roots in the teachings of Socrates, Plato and latterly Friedrich Hegel of Germany, to name just few such notables.
On the face of it, therefore, there is no getting way from the conclusion that coercive force is the deciding factor in international politics. If this were not so, US President Donald Trump in collaboration with Israeli Rightist Premier Benjamin Natanyahu could not have wielded the ‘big stick’, so to speak, on Iran, killed its Supreme Head of State, terrorized the Iranian public and gone ‘scot-free’. That is, currently, the US’ impunity seems to be limitless.
Moreover, the evidence is that the Western bloc is reuniting in the face of Iran’s threats to stymie the flow of oil from West Asia to the rest of the world. The recent G7 summit witnessed a coming together of the foremost powers of the global North to ensure that the West does not suffer grave negative consequences from any future blocking of western oil supplies.
Meanwhile, Israel is having a ‘free run’ of the Middle East, so to speak, picking out perceived adversarial powers, such as Lebanon, and militarily neutralizing them; once again with impunity. On the other hand, Iran has been bringing under assault, with no questions asked, Gulf states that are seen as allying with the US and Israel. West Asia is facing a compounded crisis and International Law seems to be helplessly silent.
Wittingly or unwittingly, matters at the heart of International Law and peace are being obfuscated by some pro-Trump administration commentators meanwhile. For example, retired US Navy Captain Brent Sadler has cited Article 51 of the UN Charter, which provides for the right to self or collective self-defence of UN member states in the face of armed attacks, as justifying the US sinking of the Iranian vessel (See page 2 of The Island of March 10, 2026). But the Article makes it clear that such measures could be resorted to by UN members only ‘ if an armed attack occurs’ against them and under no other circumstances. But no such thing happened in the incident in question and the US acted under a sheer threat perception.
Clearly, the US has violated the Article through its action and has once again demonstrated its tendency to arbitrarily use military might. The general drift of Sadler’s thinking is that in the face of pressing national priorities, obligations of a state under International Law could be side-stepped. This is a sure recipe for international anarchy because in such a policy environment states could pursue their national interests, irrespective of their merits, disregarding in the process their obligations towards the international community.
Moreover, Article 51 repeatedly reiterates the authority of the UN Security Council and the obligation of those states that act in self-defence to report to the Council and be guided by it. Sadler, therefore, could be said to have cited the Article very selectively, whereas, right along member states’ commitments to the UNSC are stressed.
However, it is beyond doubt that international anarchy has strengthened its grip over the world. While the US set destabilizing precedents after the crumbling of the Cold War that paved the way for the current anarchic situation, Russia further aggravated these degenerative trends through its invasion of Ukraine. Stepping back from anarchy has thus emerged as the prime challenge for the world community.
