  • PHYSICS, with Helen Czerski
    Aug 26 2025

    In this interview, physicist and oceanographer Helen Czerski demonstrates that physical patterns are all around us and explains how they shape our daily lives, connecting human life with the planet’s life.


    For the researcher at University College London, understanding the world means investigating these invisible patterns, especially those affecting the ocean: how the wind transfers energy to the waves, how sound travels through water to reveal hidden objects and how gases circulate between the ocean and the atmosphere via gas bubbles at the surface of the ocean.


    In the North Atlantic, for example, the ocean is inhaling carbon dioxide, taking it out of the atmosphere, while in the tropics, it is exhaling it, releasing it back into the atmosphere. «There is a natural balance between the two», insists Helen. «And what is really useful about this is that we remove that gas from the atmosphere, where otherwise it would have contributed to global warming», she explains.


    «These tiny processes, breaking waves and bubbles at the surface of the ocean, may not seem particularly significant», she adds, «but if we measure all the respiration constantly taking place across the planet, we see that the ocean is actually doing us a huge favour».


    Those very same gas bubbles revolutionised fishing. Sonar systems, which send sound into the ocean, use them to locate fish. If a fish has a gas bubble in its swim bladder – as most fish do –the sound travels differently through the animal. However, the specialist warns, «this has contributed to overfishing and impacted biodiversity in the oceans».


    «The key takeaway from all my work is how incredibly interconnected systems are. In the natural world, what happens in one place has impacts in other places», affirms Helen Czerski, citing how even a whale’s urine influences the balance of ecosystems.


    «Whales feed in the Arctic and migrate to the tropics to mate. While mating, they don’t eat, but still produce urine, which deposits nitrogen on tropical islands», explains the BBC presenter. In places like Hawaii, meanwhile, they take shelter on reefs to rear their calves and end up fertilising these environments, which are not naturally nutrient-rich.


    But this movement of nutrients has been under threat since industrial whaling began. «We removed one of the mechanisms that made the rest of the system work», and if humanity continues to remove other parts, through overfishing and introducing pollutants to the ocean, «it’s not just a chain that we’ll be breaking, but a whole web of interactions», she maintains.


    For the time being, Helen Czerski assures that the planet still has the capacity to resist, but recognises that the balance between human life and that of the planet is changing. «I think we have an enormous problem, but also that we have the means to solve it». What we cannot do, however, is carry on dragging our feet –we must act.

  • PERFECTIONISM, with Thomas Curran
    Jul 15 2025

    «If you look at the amount of spending that's going on right now, on self-optimisation, on self-help and self-improvement, we're at record levels. There’s never been more spending on these books, on these courses, on these coaching sessions… and at the same time, people have never been more miserable, more depressed and anxious».


    The warning is given by Thomas Curran, a British psychologist and expert in perfectionism, who is concerned about the rapid growth of this phenomenon and the health problems it triggers.


    In this episode of «It's not that simple», the professor from the London School of Economics explains that perfectionism is not defined by «extremely high» personal standards or by «high levels of striving to achieve them», but also by the insecurity that is the fire that goes underneath those high standards.


    Behind the extreme demands, there are always doubts as to whether we are sufficient, if we are capable of being up to it, he underlines. «This is huge and a cause for concern because perfectionist insecurities and concerns are very tightly correlated with mental health difficulties».


    An award-winning researcher, Curran shares details that show how perfectionist trends have been increasing since the end of the last century. «High levels of striving, something called ‘self-oriented perfectionism’ – perfectionism that comes from within, high self-set goals and standards – are increasing relatively modestly but, nevertheless, from a very high baseline», he reveals.


    At the same time, socially prescribed perfectionism – which has to do with the way other people expect me to be perfect - «is on an exponential trend upwards» mainly among the younger generations.


    This trend has shot up around 60% since the late 1980s. Nowadays, there is a lot of need for approval and validation from the «other», «now we rely on other people's engagement, likes and mentions for our own self-esteem», he adds.


    Nowadays, it’s not a question of just showing off material goods, but also one of showing off all your hard work and professional success. «How hard we can work, how much we can hustle or what we can build – all of this fuels the economy», but, on the other hand, it leads to burnout. «This is a very different type of showing off, but it is no less difficult psychologically, because you’re never going to be the perfect hustler, the perfect grinder».


    Maybe it's time to counteract this pressure. «Great thinkers taught us something very important: contemplation. Sitting down and reading, thinking, that is exceptionally non-productive behaviour in the short term, but could be incredibly productive in the long term», he concludes.

  • PRODUCTIVITY, with Nicholas Bloom
    Jun 17 2025

    How do we measure and assess productivity? What impact does remote working have on productivity? And what about artificial intelligence? In this episode of It’s Not That Simple, UK economist and remote work specialist Nicholas Bloom explores the dilemmas of modern management.


    At the start of the 20th century, in coal mining yards, «it was enough to count how many shovelfuls a worker dug per hour». Today, aside from a few exceptions (such as call centres), these kinds of metrics are no longer suitable for measuring productivity in an increasingly tech-driven world.


    Using Google as an example, the William Eberle Professor of Economics at Stanford University explains how measurement formulas have become far more diffuse and complex. Companies like Google measure productivity by analysing «the number of new apps or products delivered, the teams involved in development, the hours spent to complete production... and even then, it’s far from ideal», he says. «Measuring productivity is extremely difficult in the digital era».


    Bloom contends that explaining why some countries remain less productive is far more straightforward: working hours or remote work are not the issue – rather, the issue is management.


    «Working from home two days a week doesn’t reduce productivity. Plus, it affords companies a significant advantage: employees are less likely to quit, and high employee turnover is a big expense», he explains.


    Having conducted comparative studies of management practices across different sectors and countries, Bloom highlights the effectiveness of North American companies’ strategic aggressiveness: «They measure everything, set ambitious targets», and reward results quickly. In Portugal, he notes, this is not the case.


    But solutions do exist, and the economist offers several for Portuguese business leaders to consider. However, one vital solution lies outside companies’ control: reducing market regulation. Bloom believes that «the government should be like a football referee», establishing the rules of the game but refraining from excessive intervention.


    According to the winner of the Econometric Society’s Frisch Medal, competition is the driving force behind productivity within this open-market model: «The US remains the most productive country in the world because it has highly competitive markets».


    And what about the future? While the outlook may not look promising for the younger generation and their career prospects, Bloom believes AI could hold the key to a new leap in productivity. «Productivity has slowed over the last 50 years. It’s like an apple tree from which we have already picked all the low-hanging fruit, and only the harder-to-reach ones at the top are left». Could AI be the new orchard?

  • INFLATION, with Ricardo Reis
    May 13 2025

    What if a single mistake by the European Central Bank could send Europe into a recession? Ricardo Reis, one of the most awarded Portuguese economists of his generation, dismantles the myths around inflation and shows why keeping it under control is a delicate art - with inevitable costs.


    In this episode of It’s Not That Simple, the professor of Economics at the London School of Economics, dismantles the idea that this variable can be easily controlled - especially when political decisions, public expectations, and global shocks intersect.


    In this conversation, Ricardo Reis reminds that the pandemic and the war in Ukraine were two major tests for monetary policy. In 2020, central banks feared deflation and lowered interest rates. In 2021, people spent more than expected - and inflation surged. When the second shock hit - the war - expectations were already unanchored. «It was this accumulated error that made 2022 inflation more persistent».


    The response - raising rates - worked. «Inflation fell without unemployment rising, but it would have dropped faster if there had been a recession». That’s the dilemma that Reis knows well, because he is also an academic consultant to the Bank of England, the Riksbank and the Federal Reserve Bank of Richmond.


    And now? The worst is behind us, but expectations have changed. The trust in the ECB is no longer what it once was.


    Beyond that, the tariffs imposed by the US on imported goods are the next test, according to the professor. «They’ll generate domestic inflation and a recession», but the risk is global, as they trigger trade wars and could force Europe to retaliate. Could the result be a recession in Europe, as well?

  • SPACE EXPLORATION, with Ezinne Uzo-Okoro
    Apr 15 2025

    Are we safe hovering in the unknown? Harvard researcher and former assistant director for Space Policy at the White House, Ezinne Uzo-Okoro, is the guest of this «It's not that simple» edition.


    In this conversation, Ezinne explains how satellites and space technology are already protecting lives on Earth - from monitoring the climate to anticipating disasters.


    But she also discusses the real risks we face: space junk, the increasing privatisation of space and the lack of clear global regulation.


    With the end of the International Space Station planned for 2030 and new commercial players entering orbit, the Space Policy advisor raises the question: are we prepared for this new space race?


    Exploring space is no longer science fiction - it's a matter of survival.

  • Artificial Intelligence, with Neil Lawrence
    Mar 18 2025

    AI: a dangerous threat or an indispensable tool for today and the future? «Artificial Intelligence is the most disruptive technology we've ever seen», claims Neil Lawrence, DeepMind Professor of Machine Learning at the University of Cambridge. However, he also believes that AI «is the continuation of a technological revolution» in how we share information via computers.

    Speaking in Lisbon, the guest of this edition of «It's Not That Simple» highlighted a critical issue regarding AI usage: «It is not being used in the areas people are asking us to use it: health, social care, education or security.»

    While optimistic about the relationship between humanity and AI, Lawrence acknowledges the difficulties in regulating such a rapidly evolving field. He warns against leaving regulation to «inflexible and under-resourced» regulators to «decide the future for us all.»

  • GLOBALIZATION, with Anil Gupta
    Feb 4 2025

    There is a clear Cold War between the US and China, but it differs from the one between the US and the Soviet Union and is «far more dangerous». The warning is given by Anil Gupta, the renowned expert on globalization, emerging markets and innovation, who guarantees that China is not, in economic terms, a «pygmy» like the Soviet power was compared to the American «giant».


    Analysing what the specialist considers to be «the biggest geopolitical issue of our time», the expert argues that China is a «technological, industrial, economic and military power», pointing out that the relationship with the US is not really improving.


    In addition to the clash between superpowers, Anil Gupta says that «the growth of emerging markets» has also fuelled geopolitical tensions.


    While in 2000 there were 20 emerging economies, today their number has more than doubled. And the growth of these economies is expected to remain stable over the next few years, emphasizes the expert. This means that the emerging markets - China and India, but also Indonesia, Brazil and Nigeria - are becoming not only important in economic terms but also in political terms.


    Rated by Thinkers50 as «one of the world's most influential management thinkers», Anil Gupta recalls the risk associated with supply chains, which the pandemic has already highlighted. The case of medical equipment used in the US is paradigmatic. Over the last 20 years, most of the gloves used by US surgeons have come from China. ‘In the event of a conflict with China, ‘would the US want to be dependent on such a simple item?’.


    A positive aspect of globalization is technology. In this interview, Gupta considers that ‘Artificial Intelligence is the most powerful technology that mankind has ever invented’.


    But he reminds us of the risks associated with it in the long term. «In 50 years, will AI treat humans the way we treat ants today?».

  • BIOTECHNOLOGY, with Andrew Hessel
    Jan 7 2025

    Will we be able to programme the human genome like we programme computers? And will we be able to stop ageing or create medicines and vaccines in record time? Geneticist and synthetic biology pioneer Andrew Hessel explains how this field could transform medicine, making it possible not only to diagnose but also to cure diseases in a more effective and personalised way.


    Hessel draws parallels between programming a computer and programming a cell, highlighting how the manipulation of genetic code is opening doors to innovative treatments and advances in longevity.


    Today, DNA sequencing already plays a crucial role in medicine, but synthetic biology promises to go even further, offering the ability to alter microbes to improve health and slow down natural processes such as ageing.


    However, all these advances face ethical challenges. The manipulation of living organisms, especially in humans, raises questions about the limits and responsibilities of using this technology.


    Hessel warns of the risks of abusing synthetic biology for financial, political or religious reasons, but believes that the democratisation of these tools can be a positive force for humanity.
