The Science of Racism – evidence that speaks for itself

Farrah Jarral in The Guardian:

It was over schnitzel and mash that my friend’s Bavarian grandparents decided to call me a “black devil”, chuckling all the while. Breaded chicken has since been my madeleine, taking me back to racially charged moments I’ve not known quite how to interpret. Is it really racist if they didn’t mean to be rude? What if they have dementia? And if racism = prejudice + power, was being called a black devil while I choked down some potatoes even that big a deal, given that I felt in no way disempowered in the company of my tiny, elderly hosts?

In his succinct and bingeable book The Science of Racism, professor of social psychology Keon West begins by acknowledging that society doesn’t agree on even the most basic aspects of racism, let alone its finer points. Indeed, roughly half of Britons don’t believe minorities face more discrimination than white people in various areas of life. Yet far from being a set of hazy, unanswerable philosophical questions, many of the unknowns about racism are empirically testable, especially if researchers design clever studies.

How to trick the immune system into attacking tumours

Saima Sidik in Nature:

Scientists have disguised tumours to ‘look’ similar to pig organs ― tricking the immune system into attacking the cancerous cells. This ruse can halt a tumour’s growth and even eliminate it altogether, data from monkeys and humans suggest. But scientists say that further testing is needed before the technique’s true efficacy becomes clear. It’s “early days” for this novel approach, says immuno-oncologist Brian Lichty at McMaster University in Hamilton, Canada. “I hope it stands up to further clinical testing,” he adds. The work is described today in Cell1.

Viral trickery

To devise a strategy against cancer, the authors took a cue from a challenge facing people who receive organ transplants: the human immune system recognizes transplanted organs as foreign objects and tries to eliminate them. This challenge is especially acute for transplanted pig organs, which could supplement the supply of donated human livers, kidneys and more. But human antibodies immediately attach to sugars that stud the surfaces of pig cells, leading to rapid rejection of the transplanted tissue. (Pig organs transplanted into humans are bioengineered to forestall the antibody response.) Immunologist and surgeon Yongxiang Zhao at Guangxi Medical University in Nanning, China, wondered whether he could harness this runaway immune response and direct it against tumours.

The Inscrutable David Lynch

Simran Hans at The New Statesman:

Twin Peaks first aired in 1991. A tragic and often frightening mystery, it centred on the violent murder of a beautiful teenage girl in a strange, small town nestled in the mountains of the Pacific Northwest. The protagonist was a handsome FBI agent who drank black coffee and spoke in riddles. There was a lot of spontaneous dancing fuelled by a bizarre, forbidding undercurrent of danger. I didn’t understand it at all. I was gripped. I became obsessed with its images of Americana: desolate diners and roadside dive bars, clanking industrial machinery (the fictional town of Twin Peaks has a sawmill), flanked by jaw-dropping natural beauty.

It was a great introduction to many of the director’s long-standing preoccupations: the rot of evil, the mysteries of desire, parallel worlds and the portals to them. The show featured a curdled nostalgia for the 1950s, the music of Julee Cruise, and contained much discussion of the weather (in 2020, Lynch started publishing charming daily weather reports on YouTube), and music from the 1950s. Like his most beloved and best-known film, the Blue Velvet (1986), it deals with the utter devastation of losing one’s innocence.

We should take AI welfare seriously

Robert Long at Experience Machines:

Image generated by GPT4 when asked by Morgan Meis what it would see if it looked in a mirror.

We’re likely to get confused about AI welfare, and this is a dangerous thing to get confused about.

And even though some people still opine that AI welfare is obviously a non-issue, that’s far from obvious to many scientists working on this the topic who take it quite seriously. As a recent open letter from consciousness scientists and AI researchers states, “It is no longer in the realm of science fiction to imagine AI systems having feelings.” AI companies and AI researchers are increasingly taking note as well.

This post is a short summary of a long paper about potential AI welfare called “Taking AI Welfare Seriously“. We argue that there’s a realistic possibility that some AI systems will be conscious and/or robustly agentic—and thus morally significant—in the near future.

Reflecting on the Risks of ‘Mirror Life’

Michael Kay at Undark:

In December, 37 colleagues and I published a paper in Science arguing that mirror bacteria — self-replicating, synthetic cells whose every component exists in its mirror-image form — could indeed pose incredibly grave dangers if successfully created. First, they would likely evade most human, animal, and plant immune system responses because these have evolved to tackle natural bacterial threats, not mirrored ones. That intrinsic resistance could lead to widespread, lethal infections in many species (independent of any other factors that make pathogens dangerous, like toxins they can produce). Second, our world is not overrun with natural bacteria partly because they are kept in check by other organisms, such as viruses and amoebae, that prey on them. To the best of our current knowledge, reversed molecular structures would likely give mirror bacteria significant resistance to these predators, potentially enabling them to grow largely unchecked in a wide range of ecosystems.

We shouldn’t lose sleep, though. Nobody is currently close to creating a full mirror bacterium. No one has even achieved the much simpler feat of creating a natural bacterium from its individual components; doing so in mirror form would be an extraordinarily complex undertaking that could take decades. Our intention in publishing our paper was to kickstart the conversation about the potential risks long before they materialize.

What makes some of us crave self-insight more than others?

Christoph Heine at Psyche:

We found that people varied meaningfully in the strength of their self-insight motive. While it seems to matter a great deal to some people, others do not care about it that much at all. Perhaps you have noticed this among your friends and colleagues, with some of them being far more self-curious than others.

This led us to wonder what kind of a person has a greater self-insight motive. Is it the spiritual seeker who dresses in linen and practises yoga half of the day, or is it the manager who drives an expensive car and lives in a big house, suddenly experiencing a midlife crisis, asking if there is more to life than this? Of course, these are comical stereotypes so we couldn’t answer those exact questions. However, we did give our participants some established personality questionnaires and looked to see how other aspects of personality correlated with their scores on the self-insight motive questionnaire. Rather than throwing a bunch of statistics and correlations at you, I will tell you what we found out about the typical self-insight motivated ‘persona’. Think of it as the kind of profile that marketing folks often create to imagine their typical customer. Just remember, this is a major oversimplification of what were more complex relationships in our data.

We found that the typical persona with strong self-insight motive is a relatively young and educated individual who’s curious, open to new experiences, and concerned about maintaining their close relationships. Picture someone who constantly seeks ways to improve themselves. Finally, we also found that part of the persona is wanting to be admired by others.

Top financial watchdog warns climate change set to trigger market panics

Martin Arnold and Lee Harris in the FT:

The world’s financial stability watchdog has warned that disasters caused by climate change are increasingly likely to trigger broader panic in financial markets.

The world breached 1.5C of warming above preindustrial levels for the first time last year, raising the prospect of more environmental disasters.

The Financial Stability Board said the financial damage of climate shocks such as floods, droughts, fires or storms could cause a broader pullback in lending and downturn in investor confidence.

“Banks could reduce lending, including for recovery to already vulnerable households and corporates,” the body, which brings together the world’s central bankers, ministers and regulators, said. “There could also be an abrupt, broad-based repricing of climate-physical risk, as the expectation of larger future losses are incorporated into current prices and impact sectors and jurisdictions not currently directly affected by disasters.”

The report comes amid broader concerns about the capacity of the insurance sector to cover losses associated with climate change following devastating fires in Los Angeles that are estimated to have caused tens of billions of dollars’ worth of damages.

The impact of artificial intelligence on macroeconomic productivity

Masayuki Morikawa in Vox EU:

With the rapid diffusion of artificial intelligence (AI), its impacts on productivity and the labour market have attracted attention. Many studies have been conducted on the impacts of industrial robots on productivity (e.g. Graetz and Michaels 2018, Kromann et al. 2020, Cette et al. 2021, Dauth et al. 2021) due to the availability of International Federation of Robotics (IFR) data on robot utilisation by country and industry. However, the quantitative impact of AI on productivity is not yet well understood, mainly due to a lack of statistical data on the use of AI.

Recently, several studies have reported findings from randomised experiments on specific tasks in which AI has a large positive effect on productivity (e.g. Brynjolfsson et al. 2023, Kanazawa et al. 2022, Noy and Zhang 2023, Peng et al. 2023). These studies are valuable contributions that reveal the causal effect of AI on productivity, but it is impossible to infer macroeconomic impacts from these results because the studies only cover the very narrowly defined tasks of customer support, taxi driving, writing tasks, and software programming.

Acemoglu (2024) estimates the medium-term effect of AI on productivity in the US as the percentage of tasks affected by AI multiplied by task-level cost savings based on these existing task-level studies. According to his study, the macroeconomic impact of AI is non-negligible but small, with a cumulative total factor productivity (TFP) increase of less than 0.7%. However, he noted that there is huge uncertainty about which tasks will be automated, and what the cost savings will be.

Sunday Poem

““Art is the proper task of life,”
………………………. —Nietzsche

Inner Life

Art is an essential part of life. Without its depth
and enrichment, our lives would dry like desert dew
at the break of dawn.

Art enhances human experience by offering beauty,
inspiration, and a means to navigate and interpret the
complexities of being, the magic, the mayhem,
and the throbbing mysteries surrounding us.

In the words of Jean-Luc Godard:
Art attracts us only by what it reveals
of our most secret self.

The creative act is an activity of our inner life,
the dominion of spirit over the material world
serving as a metaphysical lens enabling us
to perceive life with greater depth and nuance.

The Women Refusing to Participate in Trump’s Economy

Simmone Shah in Time Magazine:

Sara Belhouari, a financial advisor based in Brooklyn, is implementing what she calls “financial activism,” a process that involves spending her money with more intentionality. She’s been rethinking her support of large corporations. With companies—including Amazon and Uber—pledging donations to Trump’s inauguration fund, Belhouari plans to stop supporting businesses that don’t align with her values. “These corporations have so much money, influence, and power.” she says. “A lot of the companies that I’ve chosen not to support are donating to politicians that are going to push forward really harmful practices.”

Nabihah Ahmad, a student at Columbia University, has long made it a point to support businesses that prioritize things like sustainability or fair labor practices. Last year, she built an online search engine to help people find alternatives to products from companies profiting off the Israel-Hamas war. In the wake of the presidential election, she expanded it to champion black-owned and women-owned businesses in the United States. She says that millions of people have visited the site each month, and that it’s a sign that people are becoming more cognizant of their purchasing power and its impact. “There’s just been this societal shift towards being conscious consumers and using our purchasing power correctly when it comes to climate change or political issues,” she says. “Our money very much controls the outcomes of all of these things.”

Why AI Progress Is Increasingly Invisible

Garrison Lovely in Time:

On Dec. 20, OpenAI announced o3, its latest model, and reported new state-of-the-art performance on a number of the most challenging technical benchmarks out there, in many cases improving on the previous high score by double-digit percentage points. I believe that o3 signals that we are in a new paradigm of AI progress. And François Chollet a co-creator of the prominent ARC-AGI benchmark, who some consider to be an AI scaling skeptic, writes that the model represents a “genuine breakthrough.”

However, in the weeks after OpenAI announced o3, many mainstream news sites made no mention of the new model. Around the time of the announcement, readers would find headlines at the Wall Street JournalWIRED, and the New York Times suggesting AI was actually slowing down. The muted media response suggests that there is a growing gulf between what AI insiders are seeing and what the public is told.

Indeed, AI progress hasn’t stalled—it’s just become invisible to most people.

In Our Hands

Text by Joshua Craze, photography by Wolf Böwig, in Mouse Magazine:

Dear Wolf,

You sent me four images for my trip, and I thought of them like charms, meant to keep me safe. I was to go to Juba and then head to the South Sudanese border with Darfur, before plunging into the war that raged to the north. On the plane from Nairobi to South Sudan’s capital, I kept staring at your images on my laptop screen, as if I were a detective investigating a crime scene. There were two collages and two photographic polyptychs. What hidden logic led you to send me these pictures, and not others? I closed my laptop before the plane banked down over the Nile with the internal relationship between the images still mysterious to me.

I arrived in Juba on Valentine’s Day, to be greeted by a public letter from a leading South Sudanese politician, accusing me of being in the pay of a rebel leader. As a precaution, I spent the night at my hotel, and looked, once again, at your images, which transported me through time. I suddenly remembered the sadness of a demobilized Mende militia fighter sitting disconsolately in his carpentry workshop, surrounded by garbage. Soon, other memories emerged. Of scholars trapped in the binary brutality of the war on terror. Of sorcery and spells, proven and alleged. Of violence, abstract, and all too concrete.

Soaring wealth inequality has remade the map of American prosperity

Tom Kemeny at The Conversation:

One need only glance at headlines about Jeff Bezos, Elon Musk and other super-wealthy individuals to understand that wealth in America is increasingly concentrated in fewer and fewer hands. Inequality is sharply on the rise.

Until now, however, little has been known about where the richest households are located, which cities are the most unequal and how these trends have evolved.

In a new analysis I conducted with my colleagues, we reveal where wealth is most concentrated within and between communities, cities and states. The result is GEOWEALTH-US – the first data that tracks the geography of wealth in the United States and how it has changed since 1960.

The overall picture is worrying. The wealthiest cities in the U.S. are now almost seven times richer than the poorest regions, a disparity that has almost doubled since 1960. Meanwhile, especially in urban coastal areas, wealth has become highly concentrated in the hands of a few. The picture from the geography of wealth suggests we are even more divided than we thought.
