Toad in the hole
If we are looking a little lorn this week, with our mouth opening and closing to little effect, it is principally because we are staring at “Finding love in a hopeless place: A global database of misdirected amplexus in anurans”. This is a new paper in the journal Ecology by Filipe Serrano and his colleagues at the University of Sao Paolo in Brazil. No amount of science words can gloss over the fact that it amounts to a spreadsheet of all the instances recorded in the scientific literature in the past century of frogs attempting to mate with things that they shouldn’t.
It can’t be easy being an amphibian, as evidenced by the touching – in a very real, excessive sense – story recently reported in this magazine of male Santa Marta harlequin toads in Colombia that cling to females’ backs for up to five months in hope of mating (23 April, p 19).
The new database conveniently tags misdirected encounters with hour, month, year and geographical location. “We recorded a total of 282 interspecific amplexus, 46 necrophiliac amplexus and 50 amplexus with objects or non-amphibian species, with USA and Brazil being the countries with the highest number of records,” the authors report.Advertisement
“Why?” asks a colleague. Ah, well, if we knew why we were doing science in the first place, that wouldn’t be science, would it?
Broken-down wind
Many of us have a special place we go when we want to think. In Feedback’s case, we are often accompanied by Think, a journal of the Royal Institute of Philosophy that promises “philosophy for everyone”.
We think it may be getting a little too Everyman with a contribution in the latest issue entitled “The metaphysics of farts”. If the last item brought the sound of the barrel scraping, listen to us now drill right through.
What is a fart? An act, that of breaking wind, or a thing, the resultant smell? Author Brian Capra tackles this question head on, highlighting contradictions between the “essential-bum-origin” and “phenomenological” views that, he submits, mean both can’t be true.
Via a thought experiment asking if two people fart in a lift, how many farts there are, and the obvious answer – does it matter? – he concludes that a fart-thing must proceed from a fart-act, but a fart-act doesn’t necessarily produce a fart-thing, and, so, “we are led to an outlook similar to Descartes’s view of the mind: on the phenomenological view, the essence of a fart is given to us in our olfactory experience”.
Desfartes, as a nameless colleague supplies indelicately. Ignore them, dear readers: this sort of thing is what makes philosophy and thinking such valuable activities. Now, could someone open that door? It is closer than two toads in the mating season in here.
Got my goat
We note in passing – noiselessly, of course – that the same author wrote an article in Philosophy Now that uses elementary principles of model logic to prove that everything is a goat. For those still asking “why?”, we merely note the goat’s genus is Capra, and there may be more than a hint of solipsism in the argument.
On a roll
We would personally prefer it if everything were cake. Our thanks to the very, very many of you who provided ever so slightly muffled feedback on our recent item on legal definitions of cake (30 April). Space fortunately does permit us to delve into the details, suffice to say that the rigour with which you treat the subject convinces us that Feedback is all one happy family with shared values and priorities.
We particularly savoured Liz Tucker’s tangential mention of a talk she went to on the history of the Lyons tea-and-cake empire that was a feature of the British landscape for many years, which stated that, at one time, the company produced 35 miles of Swiss roll a week. This conjures a mental image of a truly majestic, if slow-moving, machine. It prompts us to ask “How do you make a Swiss roll?”, to which we are sure you can supply the punchline.
Like a lead…
Carl Zetie is perplexed by the appearance in his Facebook feed of an advertisement from a software company called Zeplin, whose corporate logo is an airship of almost that name. “Companies ship 20% faster using Zeplin,” it promises. Historically speaking, this seems an odd choice of corporate metaphor, and we do hope there is no crashing and burning on arrival.
Talking tough
Those were unsettling times, as are these. So it is good to know that the defence of the realm is in no-nonsense hands, as per a tweet from the University Royal Naval Unit Edinburgh, sent to us by Ceri Brown. “Our first training evening after Easter was a very detailed and informative brief from the Defence Nuclear Organisation on the UK Nuclear Deterrent. Thank you to Captain Tough and his team for the briefing.” With that exemplar of The Name Thing That Shan’t be Mentioned, and to employ a military phrase whose correct usage has generated lively debate from you before (3 April, 24 April and 8 May 2021), it is, from this Feedback, over and out.

THE complexity, community and precarity of the planet are highlighted in these works from Our Time on Earth, a new exhibition at the Barbican Centre in London. The show aims to “ignite a sense of hope and courage, and to shift people’s mindsets to reconnect with the natural world”, says co-curator Luke Kemp.

Waste from Swedish firm Boliden was dumped near a town in ChileARICA LAIKA FILM AND TELEVISION
Arica
Lars Edman and William Johansson
Selected UK cinemasAdvertisement
FORTY years ago, Boliden, a Swedish multinational metals, mining and smelting company, sold nearly 200,000 tonnes of smelter sludge rich in mercury, arsenic, lead and other heavy metals to the Chilean reprocessing company Promel. The latter dumped most of it next to a row of houses in Arica in northern Chile.
Over the years, this community of low-income families swelled until it surrounded the site of contamination. A generation of children grew up playing in the sludge. In 1999, the Chilean government struck an uneasy peace with those affected by this avoidable catastrophe. Promel no longer exists. Families closest to the site have been evacuated.
Swedish film-maker Lars Edman returns to the country of his birth and the site of his 2010 Toxic Playground documentary for a follow-up. Arica concentrates on the legal case against Boliden, whose due diligence on toxic materials has come under serious question. Boliden denies responsibility, saying it followed applicable regulations and believed the waste would be processed safely. Any negligence, it argues, is attributable to Promel and the Chilean authorities.
The chief protagonist of Edman’s first film was Rolf Svedberg, Boliden’s former head of environmental issues. It was his site visit and report that green-lit the sale and transport of what Boliden’s legal team calls “material of negative value”.
Brought face to face with the consequences of that decision, and hosted by a community riddled with cancer and congenital conditions, Svedberg’s distress was visible. A decade on, though, he has the legal case to think of, not to mention his current role as a judge at Sweden’s environmental supreme court.
Boliden’s legal consultants bring in experts who assemble arcane explanations and a ludicrous wind-tunnel experiment to show that living next to tailings containing 17 per cent arsenic couldn’t possibly have affected anyone’s health. Opposing them are 800 plaintiffs (out of a community of 18,000) armed with a few urine tests from 2011 and evidence that would be overwhelming were it not so frustratingly anecdotal.
One interviewee, Elia, points out houses from her gate. “The lady who lived in the house with the bars,” she says, “sold the house and died of cancer. Next door is Dani Ticona. She had aggressive cancer in her head and died too. And her son’s wife had a baby who died…”
Boliden’s team performs a familiar trick, sowing doubt by suggesting that lab and field science are the same thing, with identical standards of proof. If the company had to address average consumers rather than Arica’s low-income residents, it would long since have saved money and its reputation by owning the problem. But Boliden deals with corporations and governments. Its image rests on problem-free operations; it pays to stay silent.
In the end, the community loses, but in 2021 the UN sent experts into Arica. Their findings shamed both the company and the Swedish government.
Law is a rhetorical art. We like to think justice can be scientifically determined, but that is to misunderstand science and the law. Tragedy, poverty, blame and shame cannot be reduced to numbers. Protest, eloquence and argument are as essential for justice as they were in the making of this elegiac film.

THE idea that we can improve our gut health by eating foods containing live “friendly” bacteria, or probiotics, dates back to the early 20th century. Ilya Mechnikov, a Russian biologist whose work on immunity led to a Nobel prize, postulated that consuming soured milk fostered beneficial bacteria in the intestines. He claimed that people in Bulgaria who ate yogurt lived longer as a result, and his ideas helped to popularise yogurt in western Europe and North America.
The main types of bacteria found in commercial yogurt are Lactobacillus delbrueckii subspecies bulgaricus and Streptococcus thermophilus. Several studies have found that … More

State laws could restrict abortion in large parts of the US, and other reproductive healthcare offerings may be at stake if Roe v Wade is overturned

THE US Supreme Court appears to be on the brink of repealing Roe v Wade, the 1973 ruling that protects the right to an abortion in the country. Should the seminal case be overturned, it will be left to each state to decide whether abortion is legal for its residents.
According to the Guttmacher Institute, a reproductive rights research group, 13 states have so-called trigger laws ready that would effectively ban all abortions as soon as the ruling … More

People from privileged groups may misperceive equality-boosting policies as harmful to them, even if they would actually benefit.
Previous studies have found that advantaged people often don’t support interventions that redistribute their resources to others who are disadvantaged, in zero-sum scenarios where there are limited resources.
Now, researchers have explored the degree to which people from advantaged groups think equality-promoting policies would harm their access to resources, in scenarios where the strategies would benefit or have no effect on their group, while bolstering the resources of a disadvantaged group.Advertisement
Derek Brown at the University of California, Berkeley, conducted a series of studies involving a total of more than 4000 volunteers.
In one study, they presented white people who weren’t Hispanic with policies that didn’t affect their own advantaged group and benefited a disadvantaged group that they did not belong to – people with disabilities, those who had committed a crime in the past, members of a racial minority group or women. Importantly, the team told participants that resources – in the form of jobs or money – were unlimited.
For example, one policy would direct more money to mortgage loans for Latino homebuyers without limiting how many mortgage loans were available for white people.
Participants were then asked to rank how they thought the policy would affect the advantaged group’s access to resources on a scale from greatly harmful to greatly beneficial. The team found that, on average, advantaged people perceived equality-boosting policies as harmful to their resource access, even though they were told that resources were boundless.
“We find that advantaged members misperceived these policies as a sacrifice to their group, even when that’s not the case,” says Brown.

The researchers then asked participants to consider a win-win scenario involving equality-promoting policies that benefited both the disadvantaged and advantaged groups – but the latter to a lesser extent. People were also asked to consider inequality-enhancing policies that would reduce access to resources for everyone.
In this case, the team found that most advantaged people thought equality-enhancing policies with benefits for all would be more harmful to them than inequality-enhancing polices that came at a cost to the advantaged group.
“We thought, maybe if we make a win-win or mutual-benefit situation, then maybe [advantaged people] will see the equality-enhancing policies as helpful. But they didn’t,” says Brown.
Advantaged people tended to see equality-promoting policies as less harmful to their resource access if they benefitted people who were disadvantaged but who shared an identity with them. For example, white participants generally thought they would lose less from a policy that directed relatively more money to disadvantaged white people, compared with a policy that gave disadvantaged Black people the same benefits.
“Advantaged people saw these policies more accurately when we made salient a disparity within their own group versus one that occurs between different groups,” says Brown. “This suggests that when we identify ourselves with a certain group, and see a disparity occurring within our group, we are motivated to reduce that in-group disparity.”

In another experiment, the researchers asked a diverse group of participants to take a bogus personality test and then assigned them into a made-up advantaged group. Again, they found that people tended to misperceive equality-promoting policies as harmful even when they benefitted the advantaged group. This suggests that anyone at an advantage – for any reason – may misperceive beneficial equality-boosting policies as harmful.
“It’s pretty troubling what we found. [But] I think people have the capacity to believe in these policies. And I think there’s a way forward, we just have to find it,” says Brown.
Education could help to tackle inequalities by making people more aware of this tendency to misperceive equality-boosting policies that would actually benefit them, says Brown.
“It was an ambitious series of studies that did an excellent job of ruling out alternative explanations,” says Dan Meegan at the University of Guelph, Canada. “The work paints a pretty dark picture for those trying to convince people to support policies designed to reduce intergroup inequality. The authors gave their participants every opportunity to see that helping disadvantaged groups need not come at the expense of advantaged groups, to no avail.”
“In terms of reliability and importance, this research checks all the boxes. What I would say is the fact that [the findings] aren’t surprising is alarming to me,” says Shai Davidai at Columbia University in New York.
Further work will need to establish if the same behaviour applies to people outside the US, although Brown and Davidai think it probably will.
“My own and others’ work has already shown that zero-sum beliefs replicate in many cultural contexts and across different nations, and I would not be surprised if this is the case for the current work as well,” says Davidai.

Memories are subject to the same pressures as fashion in Glitterationurdongel/Getty Images
Eversion
Alastair Reynolds
GollanczAdvertisement

YOUR autobiographical memory can’t be trusted, and science has determined that this isn’t a bug, but a feature. The remembered stories from which we braid our identity bend and swerve to serve the narrative needs of our circumstances because our minds happily trade veracity for coherence and narrative. This strange space between recollection and construction is explored in two mesmerising books out this month.
Eversion by Alastair Reynolds concerns itself with how this constant process of layering and recasting can create meaning and purpose in the most desolate circumstances. The story starts on a ship dodging icebergs in the North Sea during the 17th century, and unfolds into a virtuoso genre-hopping puzzle.
It isn’t every day you get to experience a perfect collision of the Romantic macabre of Edgar Allan Poe and H. P. Lovecraft with The Usual Suspects and 2001: A Space Odyssey. So much of the book’s joy is working out which bits are real and which are misdirection on the way to unlocking the final mystery. Trust me, you don’t want this spoiled by more plot details.
It is no spoiler to say that Reynolds shows how such stories can be moulded to make us better humans. But memories can also be weaponised to keep our identities in stupefied thrall to capitalism, and this darker aspect gets an ample airing in Oliver Langmead’s Glitterati.
The star of this speculative satire is Simone. He is a fashionite, a rarefied type of super influencer whose every whim is lavishly catered for and documented by magazines read only by fashionites. For example, during a brief hospitalisation, he spies a regular proletarian gown among the haute couture medical gowns available to him. He complains and the item is summarily burned.
Simone and his fabulous friends and enemies are suspended in a vicious, never-ending battle for status, fought through clothes, make-up and accessories, sometimes leaving literal fashion victims in their wake. This sense of dangerously pointy high stakes beneath the ruffles and froth recalls writers like Edith Wharton, whose stories dissect the mores of the very rich who lived and schemed during the so-called Gilded Age of the 19th-century US.
Beyond a deft, wicked skewering of influencer culture, Langmead inhabits his protagonists’ fetishistic delight with the material world. His deliciously sensory prose puts you inside that colossal closet, running your fingers through the gossamer folds of a spider-silk gown.
Glitterati starts like puff pastry, a comedy of manners stuffed with buffoonery and characters whose trivial, self-inflicted miseries you can chortle at with abandon. But it ends like a shot of Black Mirror.
Simone’s lifestyle isn’t without costs. Along with the right clothes, he needs the right memories. And that is when a darker reality emerges, showing why these fluffy idiots can’t care about anything more than matching their outrageously expensive outfits to their false eyelashes.
At this point, it becomes clear that rather than being privileged scions, people like Simone are just pretty cogs in a vast apparatus that grinds humanity into capital. The reader begins to sympathise and have a stake in Simone’s ability to escape – and perhaps also starts to wonder which forces bend our own (flawed) memories.
