From a public health perspective, harm reduction is not confined to lowering biological risk alone. It must also address the behaviours that generate that risk. While HIV pre-exposure prophylaxis, or PrEP, is effective in reducing the probability of HIV transmission, it does not modify sexual risk behaviour and cannot replace personal responsibility or behavioural change.…

Responsible Leadership in the Age of Popular Vote
Introduction Modern democracies increasingly face a paradox. Leaders are elected through popular vote, yet popularity does not reliably translate into improved communities, functional cities, or stronger nations. Charismatic figures may win elections, dominate public discourse, and command loyal followings, but their tenure often leaves institutions weakened and public trust diminished. This tension forces a difficult…
Artificial Intelligence and the Purpose of Knowledge
As someone who works in education, I often think about how AI is changing the way we learn and teach. Artificial intelligence has become part of our daily routine, from helping us write to generating art or analysing data. It makes things faster and more convenient, but I sometimes wonder if it also makes us…
The Evolution of Statistical Inference: From Formulas to Computers
Statistics is the science of learning from data. Every time researchers use a sample to understand a population, they are practising statistical inference. Over the past century, the way we make these inferences has changed dramatically. Each new approach has brought a different philosophy about what “truth” means and how we can best estimate it.…
Planetary Health Through an Islamic Lens
We live in the Anthropocene, an era defined by human impact on the planet. From greenhouse gases altering the climate to plastics filling our oceans, the footprint of humankind is everywhere. While this age is often spoken of with despair, Islam offers a way of looking at the world that can transform how we live…

Rosenhan versus Cahalan: The Importance of Proper Records and Methodology in Research
In the history of psychiatric research, few studies have made an impact as profound as David Rosenhan’s 1973 paper, “On Being Sane in Insane Places.” It challenged the validity of psychiatric diagnosis and exposed the depersonalisation of patients in mental hospitals. Decades later, journalist Susannah Cahalan revisited the same study in her 2019 book, The…
Tawhidic Epistemology and the Islamisation of Knowledge in Medical Education
Introduction The modern university, especially in the fields of science and medicine, often functions within a paradigm that disconnects knowledge from values, science from ethics, and intellect from faith. This fragmented epistemology, rooted in secular modernity, results in professionals who are technically proficient but morally and spiritually unmoored. In the Muslim world, this disjunction has…
Ban Vape Now to Protect Public Health in Malaysia
Executive Summary Vaping has emerged as a growing public health and security crisis in Malaysia. Once promoted as a safer alternative to smoking, vaping is now strongly linked to nicotine addiction, youth uptake, serious health harms, and even drug abuse. The enforcement of the Akta Kawalan Produk Merokok Demi Kesihatan Awam 2024 (Act 852), effective…
Statistics and Machine Learning in Public Health: When to Use What
If you’re trained in epidemiology or biostatistics, you likely think in terms of models, inference, and evidence. Now, with machine learning entering the scene, you’re probably hearing about algorithms that can “predict” disease, “detect” outbreaks, and “learn” from data. But while ML offers exciting possibilities, it’s important to understand how it differs from classical statistical…
