Musician Historian

Musicians are usually perceived as “part of history” rather than being historians themselves. However, recent research on Bob Dylan has extended that view to portray Dylan in his role as historian as well. The issue here is more with the historical periods and references the musician, composer and song writer builds on and interprets historical events. Thereby, his thoughts and impressions on living through historical events enter into his work as an artist. Dylan is literally “doing history”. He puts events of past and present into perspective of his own making and reached authority through the non-conformist perspective, which connected him to as a performer to his various audiences. His approach to doing history consists in the re-presentation and re-creation of historical narratives. Nina Goss (2024) in her book review highlights the “irruptions of the past into the present unique in popular culture”. The re-arrangement of fact and fiction encourages us “to inhabit, question, and revise historical narratives and tropes” (p.399). Several musicians have specific ways of reflecting, sometimes critically, on history in their artistic work. Bob Dylan certainly is a very prominent example of this an has been honoured for this by the Nobel Prize for literature. It remains an interesting perspective to review composers and their choice of libretti for operas as a way of doing history. The shifts from royal drama to revolutions and popular scenes are in this line of interpreting musicians also as historians.

AI Workday

Our workdays have seen considerable changes throughout the last few days. The home office boom has allowed employees to work for extended hours from home. The there is an abundant literature on the effects of home office work on well-being or the work-life balance. Productivity gains could be reaped by employers and a better work-life balance was a lasting advantage for employees.
The increased use of AI specific to some occupations has introduced a new form of added  productivity for some occupations or professions, AI as complementarity, whereas other occupations suffered a higher risk of being substituted by AI applications.
Based on time diary data, the study by Wei Jiang et al. (2025) reports that users of AI have longer work time and reduced leisure time. Competitive labor markets increase the pressure to put in even higher hours of work. Nerds, just like workaholics, are likely to be drawn into excessive hours of work with increased health risks. Enterprises and consumers appear to be gaining more than the employees, who are at a higher risk of loosing out on their work-life balance over time.

Citizen Walk

Capitals like Paris and Berlin make great efforts to improve the walkability of their cities. After decades of focus on automotive traffic and mobility and the detrimental effects on health for several generations of people, the awareness that walking citizens are part of the solution is spreading. Citizens of Paris voted in a referendum to stop circulation of cars in 500 more streets. In Berlin pedestrians unite to mobilize more people to take to the streets as well and reclaim walking space. In high density spaces like metropolitan areas it is possible to reach all major amenities within a reasonable walking distance. The more spread out suburban area, however, leve fewer options to walk and carry your shopping or do your dily commute to work while walking. Fewer cars and pharmaceutical products sold would mean less „artificial economic growth, but more healthy and happy citizens. It will take decades again to realize such visions.

Retirement Recruitment

The debate that later retirement of seniors reduces the hiring of youth has received new attention. Paul Mohnen published a paper on the “retirement slowdown on the US youth labor market” , which demonstrates this “crowding out effect”. Moreover, the recruitment of middle aged workers is also affected, as job changes slowed down for these age groups. The surprising finding is that higher skilled youth suffers the largest reduction in employment opportunities and become “pulled” into lower skilled jobs as jo offers for lower skilled persons remained high during the observation periods (until 2017!). This evidence suggests that the well-documented firm-level effect of fewer retirement means less recruitment holds also for society as a whole. Knowing that recruitment during a recession affects young workers more than persons already in employment, the macro level effects in 2025 will be rather unfavorable for young labor market entrants.

Draft Lottery

For decades the “intergenerational effects of the Vietnam draft on risky behaviors” has been overlooked. Deza and Mezza (2025) identified several changes in parenting styles (PS) due to existence of a draft lottery. PS like uninvolved, permissive, authoritarian become more frequent. Similarly, risky behaviors of their children like smoking, drinking and drug abuse tend to increase. According to this new evidence on an old strategy to recruit military personnel the effects are not only directly on the persons drafted, but have lasting consequences onthe next generation as well. This increased overall the burden of going as well as preparing for war in the societies concerned. In view of the Russian aggression on Ukraine territory the consequences for both countries are considerable and shall be transmitted to future generations as well. Even neighboring countries fear and feel the heat of recruitment for armed conflict.

Artist Development

For many artists it takes years before they find their idiosyncratic style. Testing different forms of art before zooming in on a particular style of art is the  common trajectory for most artists. Maybe the art marker and collectors of art are in search of a “defining style” for an artist so the uniqueness becomes more easily identifiable. Being part of a group of artists has been beneficial as well. The “Neue Nationalgalerie” in Berlin makes this development of an artist, in this case Lygia Clark transparent through the organization of a retrospective devoted to her evolution from abstract paintings towards participative and more organic forms of art. Berlin offers to interact with the pieces at the exhibition. You become part of the exhibition and the happening of art instantaneously. The form stays the same, the persons interacting change permanently. The piece of art is never the same. Just the idea of it thrives. In the Corpo Colletivo the performers wear an overall, all of them are linked to each other and movements happen organically as a group rather than individually. This is like a tutorial in sociology as individuals move as part of a collective body and feel the embeddedness and multiple links to other persons (Image: Corpo Collectivo 1970, exhibit in Berlin 2025)

Robot repairs

Robots have been used mostly in industry for assembling, transport or sorting tasks. There is also a role in disassembling to enhance circularity. To repair electric or mechanic devices there is an enhanced version needed which starts with a diagnosis of the problem. Algorithms can sort out promising from dead end routes of repairs. However, the recognition of objects into things that can be repaired and those without repair potential is a worthwhile assistance. Beyond the economic and ecological rationale for repairs, there is an emotional or nostalgic sense to it as well. Maybe, from a life course perspective any object related to the teenager years of a person qualify for nostalgic value. Even simple robots or AI-assisted objects may qualify for this in future. Artificial friends will be like tamagotchis in need of repairs.

Maison de santé 1861 Berlin

In the middle of the 19th century Berlin was a small city. The area of Schöneberg (pritty hill) was still perceived as the rural outskirts and featured the first botanical garden next to the town center. A little bit more outside of Berlin the “Maison de santé” was founded as early as 1861 to cure mainly respiratory diseases and what later became the first private clinic proposing a new way to treat psychiatric disorders. Dr. Eduard Levinstein was the founder and the clinic had continued its operations for almost 50 years with his wife and sons taking the lead later on. Prof. Wilhelm Griesinger, known for the scientific approach of psychiatry was a proponent of the non-restrained approach to psychiatric disorders, which allowed persons move more freely while being supervised. The documents and the publication (1877) shown in the exhibition at Museum Schōneberg demonstrate the scientific approach to the treatment of addictions, most notably morphine, which had been widely used during the war of 1870 as tranquilizer and pain relief. The wave of addictions needed hospitals and clinics to treat these addictions. The “Maison de santé” had been established as a retreat and cure for other addictions as well. The memory of the early scientific approaches is an inspiring place and reminder to take care of all forms of addiction. Taking care of body and mind is still the state of the art approach today.

The Exhibition catalog is forthcoming, but the visits and material on display of interest beyond the inhabitants of the „Pritty Hill“. Exhibition catalog is forthcoming

Permanently anxious

„There’s a set of forces that want us to be permanently anxious“, is the phrase chosen by Tony Cokes in the exhibit just outside the „Palais Populaire“ in Berlin in 2025-5. International politics and the economic upheaval caused by Trump’s tariffs contribute to the already existing other sources of anxiety like nuclear energy and warfare. Global warming causing more extreme weather events add more man-made reasons for anxiety. The next generations will have to foot the bills we have left to them unpaid. Our current shortsightedness increases anxieties which previous generations have not known of a similar kind or in that combination. 

Community building and solidarity are ways to overcome such overwhelming anxieties. Supranational organizations like the European Union have an even stronger role to play to reassure its people with credible signs of solidarity. We are not alone in the struggle to overcome the anxiety that is creeping up around us. We are certainly stronger together than individually dealing with unspecified fears. „We shall overcome …“

Margot Friedländer memorial

Berlin has been honored by the return of Margot Friedländer who had survived the Shoa in 2010 at the age of 88. Her whole family was murdered in concentration camps by the Nazis. Ever since her return and especially after her biography had been published she was a restless ambassador in the fight against hate, exclusion and the neo-fascist movements. She has been engaged in interreligious dialogue and even through the ceremony after her death, she tried to bring together different Jewish communities in Berlin.
Irrespective of a person’s background she met everybody on an equal level.
A great example to thousands of people, she managed to meet in her life. Each time she met with pupils or students to speak about her horrific experiences she lived through the same traumatic experiences again and again, but turning this into the strength to “vaccinate” people against the deadly virus of fascism.
The day after she had been buried in her family’s grave in Berlin Weißensee people still had to queue to sign the book in her memory in the Berlin town hall. She will be remembered and missed for her unrivalled humanity and generosity. She became engaged to fight for humanity and remained an activist until her very last day at 103 years of age.

Lviv Ukraine

Small galleries can make a real difference. In Berlin the gallery “streulicht” has a selection of photos in an exhibition that portraits artist from Lviv in Ukraine. Hans Hugo Hoffmann manages in his photographs to depict the extraordinary resilience of Ukrainian creative persons who live through a protracted war of their country against the Russian aggressor. The persons embody the strength of resisting through their art work despite the wounds inflicted on their families or the people of Lviv and the whole of Ukraine due to the war. The persons portrayed try to continue their normal day to day work, knowing that nothing is normal anymore in Ukraine. “Bizarre Normality” characterizes our perspective on these artists, who are thrown into a world of events that we no longer thought might be possible in Europe. Bucha and other crimes by Russian soldiers in this Russian aggression leave traces in the faces of Ukrainian people and even beyond. We all wish that the people of Ukraine can return to “normality” as soon as possible, although we know that nothing will be normal as it was before the Russian invasion.

Leber JA

In Berlin Schoeneberg there is a memorial in preparation for the courageous couple of Julius and Annedore Leber. Julius Leber has been incarcerated several times by the Nazi officials, tortured and finally executed in Berlin. A link to the group of people trying to overthrow the NS regime (1944-7-20) caused his arrest and execution in January 1945. His wife Annedore published several accounts of the resistance movements, which existed during the NS regime. These people were aware of the fact that they were risking their life with such activities, but persisted nevertheless. We owe Julius and Annedore Leber a decent commemoration as we need to remember that such courageous examples existed even until the last few months of the NS dictatorship. The site allows for a building and learning center which could serve as an archive and encouragement to fight for democracy. It is less obvious than we thought it would be.

Local history

In Berlin and many other big cities in Germany like Munich and Hamburg there are local history projects which tell the stories of specific places or a house linked to liberation day or deportation or courageous acts during the Nazi  grip on Germany and terror across Europe. The initiative « Denkmal am Ort » has become a kind of citizen science project which brings people together to raise awareness again for the cruelties committed under the dictatorship of Hitler and the fascist political movements. Remembrance is not a passive form it can take many active forms as well by simply trying to find an answer to the question what happened during the 30s, 40 and 1950s in the house you are currently living in? Access to archives of cities and small towns can tell very surprising stories about local history. It is a great inter generational experience as well and sometimes the unspoken history turns into a great conversation about history and responsibilities. History is everywhere you just need to keep your eyes and mind open.

Constitutional Responsibility

The memory of horrors caused by Nazi-led Germany before and during the 2nd World War is our constitutional obligation in the Federal Republic of Germany since its beginnings in 1948. 80 years after the unconditional surrender this has become a state responsibility. Since the shift of tone introduced by Richard von Weizäcker on 8th of May 1985 framing the end of the 2nd WW as liberation day in Europe and Germany. On the same day, 40 years later, the top 5 political instances of democracy in Germany, president, chancellor, presidents of the parliament (1st chanber), the council of the regions (2nd chamber) as well as the constitutional court. The constitutional and moral responsibility of the crimes is not reserved to a presidential address, but all pilars of democracy in Germany committed to the narrative of a liberation of Germans and Europeans at the end of the 2WW. It is a truly European topic to celebrate the end of war jointly in all countries. This is even more the case as the memories of the last survivors of the Shoa in Europe is less transmitted by the rare survivors until today due to very old age. The impressive unity of the top constitutional powers sets a the path for a far reaching renewal of the acknowledgement of a specific constitutional responsibility to counter extremist tendencies. The speeches by Frank-Walter Steinmeier and Julia Klöckner in the Bundestag (Link in German) were remarkable in explaining in plain language, why we are happy about this liberation also in Germany. The emphasis of the end of pervasive and endless oppression and suffering caused by the Nazi-regime are an essential part of this feeling of liberation. With this commemoration Germany today has become even more a European nation which takes its historical responsibility seriously.

Lasting memory

On the 8th of May 2025 we celebrate 80 days of liberation from the Nazi regime in Germany. It is the liberation of all those who survived the horrors of oppression and war. The Nazi terror intensified  after the power grip in 1933 and reached unprecedented levels throughout the ruling of the NSDAP until the Allied Forces managed to chase down the last fighting cells and Hitler hiding in a bunker before he killed himself. Liberation was the experience of survivors all across Europe. On this day and on many other commemorations it is important to remember the 60 millions of people who died due to the Nazi terror before and during the war. The “Stolperstein” initiative commemorates the millions of Jewish people who were deported or had to flee Germany and even neighboring countries to survive. In Berlin there are yearly activities to clean the “Stolpersteine” so that they are visible enough to remain a lasting memory of the horrors. (Image: Cleaning of Stolperstein in Berlin Schöneberg organised by Michael Biel on 2025-5-4).

More sensors

The technical games that have largely replaced the traditional electrical train and cars of the boomers and older generations shift towards robotics. This has the touch of more future orientation and fun for the young used to gadgets, automation and the beginnings of AI. Therefore, the robots of our children and the ones they assemble in technical games include more sensors. Infrared emission and reception have been present already for some years, but the capture, use and application of sound in children’s games is a bit more recent. In order to assess and understand the far reaching potential of these additional sensors in our homes and environments it is essential to raise awareness through technical games and own experiences or experiments. Educational games are a useful addition to the repertoire of learning for younger generations. Accompanied learning is more likely to keep young people interested in technology and raise awareness for the potential of intrusion into privacy of technology as well. The robots will be more and more part of our daily lives. A better understanding of limitations and potentials will be necessary for all citizens in the 21st century.

Persistent beauty

The fashion industry is known for its fast turnover of beautiful designs from season to season. Some designs and often just single pieces survive the fast turnaround of the fashion industry. In many cities we find shops that sell so-called vintage cloths and objects. For men and women it is feasible to rediscover pieces of longer lasting beauty or even persistent beauty. The persistence of an image of beauty may follow the classics of designers and specific brands, but it may also have a very personal touch referring more to a person’s own life course (when we were young) or associated with freeing yourself from your family or societal context. The 60s and  70s were such time periods with radically changing images and ideas about beauty. Since then more individualised clothing seems to take hold, although there is an equally strong tendency of social or age groups to identify themselves through specific clothing, showing that you belong to the “in-group”.

Robot assistant

Adjustment processes on the labour market take their time. This means that care workers are in short supply in most countries of the OECD. Engineers as well. There are so many robots, care robots I mean, still to develop that the shortage of engineers give little hope that we shall have affordable solutions in this area for the next few years. The issue is mainly about integrating and enhancing already existing solutions. If you are a mechanical engineer you can put together motorised mechanical pieces, small motorised electric devices and, for example, small infrared emitting and receiving devises.
All this is child’s play these days (see image below). The assembling of a small Robot assistant that follows movements or can escape from a small labyrinth makes such simple structures transparent for learners and users. There is nothing magical about it, just adding together small pieces and the electronic devices to steer the movements. The learning tool from KOSMOS has been on the market for 5 years. It is a helpful device to explain basics through hands-on experience. The limits of robotics equally become more evident. Our own health and safety is concerned with larger devices cohabiting with us. A robot assistant can take on easy tasks like to follow me through my living space in old age carrying a mobile phone, keys or an emergency device. More sophisticated tasks need more sensors and AI to train the most needed and best routines. For many years this needs our input and our control as well as supervision of such devices. Most robots will operate as assistants with us in the driving seat or the boss.
This is yet another element of the “all electric society“. We are moving towards the use of more electronics assisting us from year to year.

Archi health

The links between architecture and human health are manifold. There are direct effects of healthy versus unhealthy materials in construction. For the purpose of making buildings fire proof or more resistant to heat asbestos had been used for decades which still causes health hazards nowadays in the removal of this cancerous material. Paint has to be chosen wisely as well as isolation materials. Indirect or second round effects of materials have to be considered additionally. Cement in construction uses a lot of energy in its production and has only been recycled since a few years in significant amounts. Room climate or even psychological effects of architecture have been considered to be important more seriously in recent years. A new discipline entitled “neuro-architecture” may be developed soon. Schools, sports facilities, hospitals or community centers benefit from healthy architecture. Cost benefit analyses which take into account long term effects and even recycling of materials shift the balance much in favor of health considerations also in architecture. “Fast and dirty” will be much more expensive than “slow and healthy”. Future generations will be thankful. (Image: Spreewald Primary school Berlin).

Health Systems

Comparing health systems across the EU can be complex at times. However, there seems to be a consensus that the Irish health system is an oddity within the European health systems. On the one hand Ireland is a rather wealthy country in terms of GDP, but the primary care system excludes a high percentage of people from access to it. The scientific journal “The Lancet Regional Health” published a paper and comment on this rather unique exception to the rule to offer a universal health care system to its citizens. The controversy is about the coverage of costs of a visit to a general practitioner. More and probably earlier visits to a GP reduce the (over)burdening of
hospitals later during the life course. Prevention helps a great deal to lower overall costs of a health system.
The roots of the Irish health system have been built upon “subsidiarity”, which means that the public support system should only step in, if the individuals or families are unable to cover costs by themselves. Poor households had to apply for a card giving them access to medical care free of charge. Building hospitals was the next challenge and local communities managed to raise funds in support of such additional structures. In 2025 it can be very costly to enlarge the coverage to a universal access to primary care and the challenge to attract sufficient numbers of general practitioners is a very European one. In this respect Ireland is just like any other European country again.
The question of how to best achieve a universal health care system remains an important one. Apparently, you can be rather “health poor” in an otherwise “economically rich” country.

Marx Home

The home of an influential philosopher, economist and political scientist is not easily presented like a home of a musician, a composer or an author. However, the home of Karl Marx in Trier on the Moselle river succeeds to present the biographical links of growing up in a historic city, the bourgeois upbringing of the young Marx and his formation as an independent and even revolutionary thinker of the economy and society. In 2025 the home is a museum supported by the Friedrich Ebert Foudation with a great online guide and access to additional scientific material. For authors like Karl Marx it is always of interest to follow not only the origin and evolution of the thought process, but also the shifts in the reception of his writings by subsequent generations. This part of the exhibition and an audio guide (downloadable as App).

In 2025 with an apparently ruthless capitalism at work in the biggest economy of the globe, the reminder that the economy is best to be understood as a political economy, which focuses on self-interest and profitable business deals, we find in Karl Marx still a worthwhile reminder of economic development even in the 21st century. The note-taking and studies in Exile in London are well documented in the tiny home and museum. Studying the misery of exploitation in supply chains and international commerce remains a topic of continuing interest as well.

Liszt home

In Budapest we can visit one of the longer living places of Franz Liszt or Ferenc Liszt as some Hungarians would insist to call him. The Beethoven trained Carl Czerny offered piano and music classes free of charge to the young Franz Liszt in Vienna at the age of 11. In the biography by Klára Hamburger she describes the Paris years of Liszt from 1823 until 1839 as the most important ones for the pianist and particularly for his later compositions. Born in Hungary, the son of 2 Austrian parents he was trained in Paris by amongst others the Czech professor of the Conservatoire de Paris Antonin Reicha just like Chopin, Flotow or Offenbach. Writing an opera was the “must do” for a composer who aimed for the highest possible career at the time. In a letter to George Sand, Liszt (published 1937) complained already about the social status of musicians in society as servants to the higher ranks of society. Similar to Ravel many years later Liszt was rejected as official scholar by the Conservatoire de Musique and his wish to marry a daughter of noble decent was rejected early in his career. Such experiences probably contributed to his leaning towards the romantic form of expressions in music during most of his compositions. Literature, paintings of the French romantic period and the traveling artist “voyages et pèlerinages” became influential in his creative process. The competition between composers must have been fierce at the time and despite ample opportunities to perform in public and private venues making a living from music wasn’t always easy at the beginning. More than 100 years after his death his compositions are still a challenge for all pianists and the Hungarian Rhapsodies probably his greatest homage to his early childhood.

Tchaikovsky home

During the time before the “Zeitenwende” it was easy to visit the home of the composer Pyotr Ilyich Tchaikovsky in St. Petersburg. Therefore, we refer to our memory of the visit and the already 10 years ago restrained liking and appreciation of the Russian officials for the aristocratic composer, even accused to not be sufficiently Russian in his music compared other Russian composers. The composer had diverse love affairs, which were also not conform to official doctrines. The world wide success of his compositions, mostly known for his ballet music, remains popular in the 21st century. Similar to Beethoven, the biography by Malte Korff (Tschaikowsky, in German), highlights the final symphony as his masterpiece. The seems to be a reason to study “the last works” of composers specifically. The mature compositions appear to reflect on previous work and build or comment on previous work. The 6. symphony “Pathétique” was completed in his last year of his life, only at age 53. The final IV-th piece of it is entitled “Adagio lamentoso” and ends in very calm tempo and almost silence like a withering away heart beat. To my surprise I found a similarly very quiet ending in one of his early piano composition when he was only 28 years old “Romance Opus 5, Andante cantabile”. This early piece also ended “più lento” and from pp to ppp. (compare extract of image of notes below).

Beethoven Home

The home of Beethoven in Bonn is nicely preserved and full of objects related to his life and his creative work. For the musician and composer musical instruments have accompanied him throughout his life. The visit of his home of birth offers a chance to dive into the extraordinary accomplishments of this great figure of the late 18th and early 19th century. His 9th symphony is strong as ever and the European anthem has just more than 200 years since the first performance now. The visit of the museum is still the highlight of Bonn and the App of the Beethoven House offers unique insights into and listening of his manifold compositions. Handwritten notes and a pocketbook of preparations for the symphony demonstrate the all encompassing nature of music for Beethoven. From romantic letters to the romantic music pieces, the museum has it all. Even it is a rather tiny house from the outside the inner life is as huge as it can be. It is advisable to take at least half a day for the visit much more than you would usually take for visit of a museum. The link between the biographical information and listening to linked musical pieces with a chronological context are a unique experience. This spurs the interest to listen or listen again to some of the romantic masterpieces. The App is great also to listen directly to some of the music.

Kids Gaming

The pressure on children and their parents is high to succumb to the temptation of digital and online gaming. Albeit there are many funny and learning alternatives for them if they are accompanied by an instructor to build or invent their own game. With some adaptations it is possible to assemble for example a coordination game for children which directs a small ball through a labyrinth. Add speed and tricky holes to the “parcour” and the race is on. It is little bit like hands-on physics as the speed and acceleration patterns across the parcour varies a lot. Planning, building and playing are an ensemble in this simple game. Probably also more fun than the x-th repetition of a digital game.

Owners Dispute

Renovations of housing with distributed ownerships can be a challenging experience. In Berlin you can find a few places with visible long-term disagreement about what kind of modernization should be done. More luxurious additions like balconies or triple window isolation and so on are sometimes hotly debated and contested in courts. For most buildings you cannot spot disagreements on the outside, but some constitute exceptions to this rule. One size does not fit all preferences. In a metropolitan city there is a place and a space for all such exceptions to the rule and most people after years do no longer think about such kind of diversity in preferences or budgets available for modernization. Cities put our level of tolerance to a continuous test. You probably learn to love this or eventually you leave the inner city. There are subtle differences in urban versus rural lifestyles. In the social sciences we continue to try to understand the attraction of cities as on a global scale millions of people flock to cities.

Housing renovation

The huge amount of buildings that need renovation is a task for each generation. New constructions are relatively easy to realize even to the best available standards. Particularly energy standards asking nowadays for serious isolation of buildings are easy starting from scratch. Energetic renovations of existing buildings are much more challenging and have to take into account the various stages or predilections of previous generations. Repurposing of buildings raise additional questions like transforming a family home into a representative office building. New technologies like fiberglass instead of copper cables or copper or plastic tubes instead of other hazardous materials cause additional costs and worries. The use of asbestos for interiors of previous generations has created the greatest liability for existing buildings. Technological choices of the past and also of the present (heat pump or not) have lasting consequences and sometimes even health effects. To cherish old buildings and styles is a mixed blessing as the renovation of housing confronts home renovators with more tricky challenges than building a new home. Incremental repairs might do the trick rather than all in one go renovation, however, you might enter into a situation when renovations are always on your mind. Not only the times are a changing, but homes are a changing, too.

Biased Results

The use of statistics in presenting results of research is common practice. Empirical studies are summarized using statistics and statistical methods based on samples of bigger populations are cost efficient. However, care needs to be exercised when interpreting results to guard against inappropriate conclusions derived from biased estimates. Since the topic has been highlighted and methods proposed to handle them, these methods were deemed worthy of a Nobel prize.  The basic problem of a bias due to a selective sample has been demonstrated by Stockwell et al. (2024). The authors investigate the old question, whether a little bit of alcohol consumption (per day) could be beneficial for our health. The statistical issue which needs careful examination is the construction of the control group against which the results are compared. Apparently many studies have biased control groups which included persons in the not drinking control group who had stopped drinking for bad health previously. Compared to those persons with other health conditions those drinking a little bit compared rather well. But of course such individuals should not be present in a control group. Of the control group is biased due to many persons with below average health the groups of interest consuming higher levels of alcohol do not perform so badly. Hence, interpretation of results from medical or social science studies has to consider carefully the actual or potential sources of bias. Not really a new results in statistics, but still not well known or understood by the public at large. Drug consumption as well as studies of this consumption could deserve the same sticker: handle with care.

Retirement Plans

There are debates about the best organization of retirement. The major fault lines lie between public pension systems and systems that are built based on mainly private provision. Retirement plans in either system are subject to constraints. The recent stock market turbulence has increased the amount of uncertainty people face who invested in 401K plans in the US. Some had to take an unannounced hit to their retirement savings due to the loss after Trump’s back and forth policies on tariffs (OECD Pension Outlook). High volatility of stock market prices creates an additional constraint that you are less inclined to retire when your retirement investments have overall a reduced value. You are a bit at the mercy of capital markets even in your retirement decision, irrespective of the difficulty to predict what your retirement funds will yield as returns. Quite an important lesson to keep in mind when comparing retirement systems in OECD countries. It has been all too easy to blame public pension systems for maybe lower short term interests on pension savings. Being subject to an American president concerning your retirement plans is probably not what many countries would like to have. Trump’s choices on tariffs may have consequences we did not expect to affect us so directly.

Intimate housing

The housing of famous persons has always attracted a lasting fascination. The “esprit des lieux” or the experience of the surroundings of an artist, composer, author or otherwise famous person, where most of the work had taken place is of general interest. In today’s language we would describe this as the context of creation. Biographical information and references to specific objects central to the process of creation play a crucial role in understanding what is behind human creation as it is district from AI. There are objects ( compare MAD Paris) and there are the social networks of creators. Modern biographies include both, some even in graphic forms similar to ancestry diagrams. 

The design of intimate living spaces for private life or the adequate environment for creativity are becoming more clear with the consciousness of the importance of dedicated designs of furniture, accessories and even scent. Our brains are multimodal and working as well as processing lots of information even beyond our conscious realizations. This black box of creativity is rather unique to the human brain and AI will probably take decades to emulate such complex processing. The MAD exhibition reveals that intimacy is also related to housing design and interior design. It doesn’t seem to be a random process, but habituation is part of the continued creative process.
