The annual mortality statistics and special reports on suicidal tendencies are a tough reading. OECD Statistics give a at least an approximate, comparative perspective. Reporting routines and medical confirmation of a suicide or suicidal behavior still vary quite a bit between countries. Nevertheless, the usually reported incidents per 100.000 persons remain rather abstract.
Absolute numbers speak a clear language. For example in Germany there were about 10.300 recorded suicides in 2023, France had to mourn about 9200 in 2022. To put the size of the problem in perspective it is helpful to know that in Germany all other not aging related causes of death like traffic accidents, drugs or murder make up for around 7.000 deaths per year. The targeting of resources and prevention efforts on these vulnerable people seems inevitable. However, we see only limited additional efforts to curb the problem.
A more detailed analysis of the frequencies reveals the gender and age differences. More men commit suicides and older (very old) people have higher risks. The oldest age group of men is most at risk.
Since the Covid-19 pandemic young women show rising trends in many countries again of suicidal attempts and self-inflicted wounds. Despite a continuing effort of research (Links) there is no single cause to explain the occurrences.
As a working hypothesis, which awaits empirical tests, I would look into societal factors that stigmatize persons who are made to believe or feel like they are beyond the normal spectrum of society. The lack of acceptance of diversity concerning gender, age, ethnicity, body shapes or mental states like anxiety. Poverty might cause immense distress and suffering. Large shifts in wealth in both directions cause additional risks.
It seems as if our minds and society are constantly in a kind of „regression towards the mean“ posing challenges to those furthest away from the average or perceived norms. Percentile ranks or percentile scores are commonly used to express a person’s position in a frequency distribution. For example you are better/lower than 90% of persons of your age group. Such statements might cause further distress for persons. However, summarising across several (psychological) measurements, they may yield encouraging indications as well. Actual and perceived positions in such percentile ranks add another “social risk” as perceived positions may govern behavior. 
Betrayal Politics
Most economists would hold that in free market economics there is no room for moral statements. Betrayal, therefore, is left out of most standard text book economics courses. However, more advanced courses that include strategies based on so-called “game theory”, where actors may breach prior commitments, betrayal has entered economic science. A “tit-for-tat” strategy is frequently the best “game-theoretic” solution to such strategic behavior to deter also repetition of defecting on agreed rules or bargaining outcomes. For real world applications beyond the simple strategic advice, the maths involved are quite challenging. We’ll check soon, how AI is changing that game.
Another popular economic theory is one of “gift exchange”. You gift a sum of money (or weapons for self-defense to a country) with no explicit consent that the money should be repaid (through rare earths) in peace time. A betrayal occurs, if a country suddenly asks things in return for the previous gifts. For politicians that understand themselves as “market marker” and “deal maker”, there will be a tendency to claim back a gift in order to come to some kind of gift exchange rather than an altruistic donation.
William A. Galston wrote in the WSJ (2025-2-26) naming the US political action of the 2nd Trump administration a “betrayal of Ukraine and American values”.
If free markets mean making ruthless use of “tit for no possible tat” and “gifts are always a gift exchange”, we move back to mercantile and medieval practices, where settles could claim land at gun point.
What way out of this? Adam Smith, champion of classical economics, wrote before his famous book on “The Wealth of Nations” a lesser known, precursor book on “The Theory of Moral Sentiments”. Actually, he was convinced that the one would not work without the other.
Maybe, going back to classical economics is much better than a Trump administration version of neo-classical economics in a new era of political economy 3.0. 
Election Participation Bundestag
The election of the German Bundestag 2025-2-23 has brought about many changes to the 1st chamber, the national parliament. First the voting system had changed to limit the newly elected parliament to 630 seats for a total of about 60 million people entitled to vote. 50 million voted in the election. The national average of participation in the election reached a very high 82.5%, with a range from 73.5% to 88%. Overall, it has been the highest participation rate since reunification. Political parties have to pass a barrier of 5% to be eligible for seats in the Bundestag. This regulation had been installed to avoid too many small parties to enter the Parliament as coalition building could be rather difficult and lengthy.
2 political parties missed this barrier closely, one with 4,3 % and another one with 4,97% of votes in the so-called 2nd vote, which is the vote for proportional representation in parliament after which the seats are allocated. Adding those ballots casts together, this means that for these 2 parties about 4.5 million votes do not get any representation at the national level. Several other smaller parties add more than 1 million votes, which are finally without any national representation. However, the only regionally campaigning conservative party from Bavaria reached 3 million votes (6% of votes) on the national level, which gives them a representation of 44 seats in the Bundestag.
Participation across age groups follows a relatively constant pattern. Older votes 60+ have relatively high voter turnout, whereas the younger age groups do not use the chance to vote as much as other age groups. This remains a challenge for democratic representation. The youngest have the longest time spell to live with the consequences of democratic representation and resulting policies. There are useful debates to lower the current legal age (18) to 16 years of age for voting to soften the effects of aging societies voting. Children, or currently anybody under 18, have no impact on political representation. An overweighting of families with children might fix such deficits. If the number of children drops further, we might eventually be willing to give our future a stronger voice in political elections. (Image: empty Berlin playground 2025)

Blue Sky
In the period of romanticism the associations with a blue sky were very different from today. Getting out into the sun was a kind of privilege for the “leisure class”, of people who could afford to enjoy time outside for boating, walking or other pleasures. In our technology-driven 21st century the associations with Blue Sky are more like a technically enhanced view through for example “Windows” at the news and opinion platform or “Bluesky”.
Several scientific websites that report data on blue skies and air quality more generally across the world report indicators like ozone values O3, sun intensity, micro particles 2.5µm and 10µm, Nitrogen Dioxid NO2 to name the mostly quoted indicators. Hence, just enjoying the blue sky outside isn’t the same as it was before. People working outside in the sun or at times of a blue sky but with high air pollution levels are incurring severe medium-term health risks. The Ozon layers at very high altitudes protect our skin and eyes against high UV-radiation, but O3 on the ground is tough for eyes and lungs.
Technology has come with many blessings, but the negative effects on a global scale become also more evident. Getting used to a particular lifestyle, which produces lots of emissions of aggressive fine particles will make it more difficult to just simply enjoy a blue sky.
In consideration of all these background data with regional variations, we surely need an AI-system which we can ask for advice, whether we should go outside and enjoy the blue sky with or without respiratory mask.
Romanticism has led us all the way to Californication and dangerous enshittification of the air that surrounds us. Youth and the next generations will have very different associations with Blue Sky than we have the chance to, at least, have had. 
Greening Interiors
The greening of facades of houses is an old tradition in many western countries. The outside of a home then changes colors with seasons. The home for insects and birds feeding on them makes a small contribution to biodiversity as well. Greening interiors is a more rare instance. Of course flowers and plants can contribute a lot, but there is yet more scope to green entire walls inside your home or office.
Moss has advantages to add humidity to the air. You might like the acoustic effect as well in busy environments. Taking care of moss is not easy. Professional assistance (Link) or renting options might be a good option for office buildings. The wellness enhancing effects are also interesting for some people who susceptible to the calming effects of a more natural environment. It is a matter of care and respect for air quality that is reflected in the design using green interiors.
Circularity is another advantage of the materials. We can so a lot for biodiversity if we really wanted to even in urban spaces. Global warming will force us to think more and more, and sooner than later to make use of such innovative solutions. For the time being they remain a luxury option. For the wealthy, greening interiors is easy, it much less an option for restricted budgets and people who are obliged to focus on short-term survival. However, we have to get started with the greening of our planet again, any way. 
Shoa Memorial
In the neighborhood of the Paris City Town Hall you find the Mémorial de la Shoa. There is a constant flux of visitors and pupils with their teachers passing through the rooms. They all continue to be really moved by the shocking images and their efforts to try to understand the full extent of the Shoa and the terrible effects it had even on survivors of the concentration camps. The continuation of the memory of the memories of those survivors by young people is one of the strong points of this exhibition. The transmission of memories finds many new ambassadors against the tendency to forget or downplay the horrors committed by the Nazis.
Of course it is overwhelming as an experience, but it all the more necessary to keep memories alive and guard against each tendency of denial. In the age of fake news and historical deep fakes, it will be all the more important to immunize people against any attempts of manipulation of historic truths. The availability of the information online and through youtube-videos is an indispensable next step in the preservation and dissemination of the documentaries. The Mémorial of the Shoa in Paris is an essential part of this commemoration as 76.000 Jewish persons were deported to concentration camps from France as well.(Image: Mémorial de la Shoa, Paris 2025)
January Spring
The early signs of spring in Europe usually show up in March. The monthly data from the Copernicus Climate Change Service (C3S) show that „average temperature over European land for January 2025 was 1.80°C, 2.51°C above the 1991-2020 average for January,“ (Link). The warming throughout January has several consequences. Vegetation starts into spring earlier. This means that people with allergies of early flowering suffer earlier during a year. Winter rest in animal lives will be shorter. The risks of droughts in some regions combined with floods in other regions is increased as well. Rockslides in the Alps and flooding in Italy and the Baltic states add to the costs of climate change.
Western Europe, witnessed a relatively „dry January“, even for those who kept drinking alcohol throughout the month. Heating and heating costs came down a bit and friends of gardening were surprised by some early showings of flowers of spring even in Paris neighborhoods (image below) as early as the first few days in February 2025! Strange new world. It all seems to happen a bit faster than most scientists expected. Time for adaptive behavior is shortened as well. 
United by travel
The economic rationale of profit maximization privileges the construction and management of profitable connections. For train transportation this has spurred over decades the construction of new train lines between metropolitan cities or regions. Whereas connections between Paris and Brussels are abundant and expensive from central stations those living somewhere in between the 2 cities, for example in Mons, have had little chance of access to reasonably priced and fast train connections. This neglect of the in between cities is slowly changing. Sufficiently fast and reasonably priced connections allow Europe to grow together also at the margins. Public transport as alternative to car traffic across borders for „in-between cities“ will bridge the gap between the ease of travel between metropolitan an more remote areas. There is economic growth to be reaped as connected infrastructures allow for economic as well as social mobility and joint development. This is the real European challenge ahead of us and not the numerous summits without tangible results for rural and urban populations beyond metropolitan regions. For regions spanning countries, some will be finally reunited by better public transport a kind of ecological unification. 
Hallucinations
In the 21st century hallucinations have become a daily experience. The origins of the word can be followed back at least to the Latin verb “alucinor”, best translated with “to hallucinate”. As a verb to can conjugate it, meaning that I can do it, you can do it, s/he can do it, and we may do it in groups. Roman emperors did it, American presidents do it and, of course, AI does it. Hence, it is a great subject to study.
In “Nature” 2025 we find ways to limit hallucinations of AI systems. The strategy consists mainly in repeated queries of the same type, but from different angles. It is a bit like cubism applied to informatics. On “github.com” we can follow the rankings of AI-models using LLMs based on the “hallucination-leaderboard” developed by Vectara. On “huggingface.com” you can test the Hughes Hallucination Evaluation Model. For example it is possible to run a test of your own small text documents (just like any blog entry on this webpage) and what the AI systems will do them in an attempt to summarize your ideas. According to the “hallucination-leaderboard” we are confronted with a 1.3%-4% hallucination rate of the top 25 LLMs as AI-systems. In text based systems the quantity of “errors” is a first indicator only. The seriousness of the omission, addition of wrong information or an erroneous judgment will be left to the reader or analyst to uncover.
There is now a lot to do to test various AI-systems on their “trustworthiness” in summarizing my own work. My very own daily hallucinations have become a large data base as a test case for the capacity of LLMs to make sense of them.
Based on the series of passed blog entries I shall test the capacity of AI to predict the n+1 blog entry. It would be great to know today what I am going to write about tomorrow etc. Thanks to AI I shall have (finally) a sort of intellectual life after death (not sure whether I should want this). Enough of hallucinations and on hallucinations for now, back to serious readings or fictionalized science. (Image: extract from Delphine Diallo, Kush, 2024 at Hangar Gallery Brussels). 
Existence as Eggsistence
Artists have their own ways of hallucinating. They don’t need an AI to generate ideas beyond the normal, even allowing for 2 standard deviations off the usual. As a result of the thorny question about your existence, Ram Katzir came up with the impressive statement about his „eggsistence“ being subjected to a squeezed experience. Ever increasing shares of the labor force would subscribe to this statement about the modern workplace. Each turn of the screw risks to crack up the egg‘s shell. Rather focus on the egg, try to get a grip on the screw. There are thousands if not millions who crack up under the excessive pressure of economic and political circumstances. The new platforms of food, grocery and parcel delivery at home have become the latest example of AI-assisted and algorithmicly managed screws. What is driving your eggsistence. It is about time to ask fundamental questions again. (Image: Eggsistence, by Ram Katzir 2021 in Brussels, Galilas Collection Belgium)
