Reimagining misinformation

Photo modified by staff of 'The Verge' to add a car/bicycle accident

Google’s new Pixel 9 smartphones are being heavily marketed as having their AI tool, Gemini , onboard. One of the things this allows you to do is to use a tool called ‘Reimagine’ that allows you to add new things to a scene simply via a text prompt.

It’s getting easier and easier to create realistic versions of events which never really happened. In the example above, they circumvented the cursory safeguards to simulate an accident. Fun times.

Reimagine is a logical extension of last year’s Magic Editor tools, which let you select and erase parts of a scene or change the sky to look like a sunset. It was nothing shocking. But Reimagine doesn’t just take it a step further — it kicks the whole door down. You can select any nonhuman object or portion of a scene and type in a text prompt to generate something in that space. The results are often very convincing and even uncanny. The lighting, shadows, and perspective usually match the original photo. You can add fun stuff, sure, like wildflowers or rainbows or whatever. But that’s not the problem.

A couple of my colleagues helped me test the boundaries of Reimagine with their Pixel 9 and 9 Pro review units, and we got it to generate some very disturbing things. Some of this required some creative prompting to work around the obvious guardrails; if you choose your words carefully, you can get it to create a reasonably convincing body under a blood-stained sheet.

In our week of testing, we added car wrecks, smoking bombs in public places, sheets that appear to cover bloody corpses, and drug paraphernalia to images. That seems bad. As a reminder, this isn’t some piece of specialized software we went out of our way to use — it’s all built into a phone that my dad could walk into Verizon and buy.

Where in the world is that shadow?

My son enjoys playing GeoGuessr, which is “a geography game, in which you are dropped somewhere in the world in a street view panorama and your mission is to find clues and guess your location on the world map”.

Some people are incredibly good at it, and can identify places within seconds. They use clues such as shadows, streetlights, and even the colour of soil or sand.

Bellingcat, an investigative journalism group specialising in “fact-checking and open-source intelligence” has released a tool to help figure out the location of images or video for more serious purposes. This is particularly important in a world of misinformation.

Geolocation is often a time-consuming task.

Researchers often spend hours poring over photos, scouring satellite images and sifting through street view.

But what if there was another way to quickly narrow down your search area?

Bellingcat’s new Shadow Finder Tool, developed with our Discord community, helps you quickly narrow down where an image was taken, by reducing your search area from the entire globe to just a handful of countries and locations.

Dark data is a climate concern

Nyan Cat

I mean, yes, of course I knew that data files are stored on servers and that those servers consume electricity. But this is a good example of reframing. How many emails have I got stored that I will never look at again? How many files stored in the cloud ‘just in case’?

Multiply that by millions (and billions) of internet users and we’ve got… a climate-relevant issue.

When “I can has cheezburger?” became one of the first internet memes to blow our minds, it’s unlikely that anyone worried about how much energy it would use up.

But research has now found that the vast majority of data stored in the cloud is “dark data”, meaning it is used once then never visited again. That means that all the memes and jokes and films that we love to share with friends and family – from “All your base are belong to us”, through Ryan Gosling saying “Hey Girl”, to Tim Walz with a piglet – are out there somewhere, sitting in a datacentre, using up energy. By 2030, the National Grid anticipates that datacentres will account for just under 6% of the UK’s total electricity consumption, so tackling junk data is an important part of tackling the climate crisis.

[…]

One funny meme isn’t going to destroy the planet, of course, but the millions stored, unused, in people’s camera rolls does have an impact, he explained: “The one picture isn’t going to make a drastic impact. But of course, if you maybe go into your own phone and you look at all the legacy pictures that you have, cumulatively, that creates quite a big impression in terms of energy consumption.”

Cloud operators and tech companies have a financial incentive to stop people from deleting junk data, as the more data that is stored, the more people pay to use their systems. “There are maybe other big contributors to [greenhouse gas] emissions, which maybe haven’t been picked up. And we would certainly argue that data is one of those and it will grow and get bigger, particularly think about that huge explosion but also, we know through forecasts that in the next year to two, if we take all the renewable energy in the world, that wouldn’t be enough to accommodate the amount of energy data requires. So that’s quite a scary thought.”

There is no such thing as a life that makes sense

Doormat covered in leaves saying THE GOOD KIND OF WEIRD LIVES HERE

I definitely agree with the author of this post that there a couple of wonderful things about reading history. First, you realise that almost everyone in the past had it much harder than you do, which puts things in perspective. Second, you realise that there’s many and varied ways to live a happy and/or flourishing life.

In addition, the passing comment about credentials not mattering when people realise you’re obsessive enough about a certain area is probably an insight worth unpacking.

Most of my friends have life paths that go something like this: they got ruinously obsessed with something to the exclusion of everything else and then worked on it. And eventually that failed or succeeded and then they got ruinously obsessed with something else and started working on that. And it turns out that if you’re obsessive enough the credentials thing sort of goes away because people are just like, oh, you’re clearly competent and bizarrely knowledgeable about this thing you’re obsessed with, I want to help you work on it.

If you operate like this way you end up with a weird life because in a conventional career path there are all these rules and customs you’re supposed to follow, like you’re supposed to major in W in undergrad and get X internship and then go to Y for grad school and then work at Z. The truth is, most of the people I know are just too ADHD or impatient or unconventional to follow the path that’s expected of them. They may not have even been aware of what the “normal” thing to do was. And I’m certainly not recommending that or glamorizing it because rules and customs exist for a reason, they are necessarily useful. But it’s helpful to know that some people end up fine even when they don’t do the normal thing.

Something I wish someone had told me as a kid is that the only real “rule” for work is that you have to be able pay your rent and not hurt anyone and not break any laws. And within those confines you can do literally anything, hopefully something you find personally fulfilling.

[…]

Reading history is useful partially because it makes you understand how varied people’s lives really are. The artists I admire have had lives that included nervous breakdowns and fleeing countries because of war and leaving their wife in another continent and writing their first novel to pay off gambling debts. That helps me remember that there is no such thing as a life that makes sense, or at least that’s not something I need to aspire to.

Google Calendar illustration trigger words

Example of Google Calendar illustrations

​If you use the Google Calendar app in ‘schedule’ view, you’ll no doubt be familiar with the automatic illustrations added for some events. While looking for a way to stop it showing an American Football instead of a ‘soccer’ ball, I came across a list of all of the different kinds of ways you can trigger the illustrations.

Those illustrations are triggered by the presence of certain codewords within your event titles. And once you know what codewords cause what illustrations to appear, you can hack the system, in a sense, and make any event in your agenda stand out with a specific illustration around it.​ ​

You get water from food as well, you know

Person drinking water

It’s always puzzled me when people drink huge amounts of water. Whether it’s for ‘detox’ reasons, as part of a diet, or something else, it always seems to be tinged with a bit of moral showboating.

I do a fair amount of exercise. I drink water with some BCAA powder in it when I do. Other than that, I have a couple of cups of tea a day and water with my meals. Turns out, this is probably the right approach.

It is a common belief that you have to drink 6-8 glasses of water per day. Almost everyone has heard this recommendation at some point although if you were to ask someone why you need to drink this much water every day, they probably wouldn’t be able to tell you. There is usually some vague idea that you need to drink water to flush toxins out of your system. Perhaps someone will suggest that drinking water is good for your kidneys since they filter the blood and regulate water balance. Unfortunately, none of these ideas is quite true and the 6-8 glasses myth comes from a fundamental misunderstanding of some basic physiology.

[…]

You will always lose water vapour in your breath, provided you keep breathing, and you will always produce… watery-odour free sweat even if you move to the Arctic. Of course, if you move to the tropics you will produce much more sweat to compensate for the extra heat. But all told, roughly 1.5-2 litres of water loss are obligatory losses that we cannot do anything about. Those who exercise, live in hot climates or have a fever will obviously lose more water because of more sweating. Thus, a human being needs to replenish the roughly 2 litres of water they lose every day from sweating, breathing, and urination. The actual notion of 8 glasses a day originates from a 1945 US Food and Nutrition Board which recommended 2.5 litres of daily water intake. But what is generally forgotten from this recommendation is, firstly, that it was not based on any research and that secondly the recommendation stated that most of the water intake could come from food sources.

All food has some water in it, although obviously fresh juicy fruits will have more than, say, a box of raisins. Suffice it to say that by eating regular food and having coffee, juice or what have you, you will end up consuming 2 litres of water without having to go seek it out specifically. If you find yourself in a water deficit, your body has a very simple mechanism for letting you know. Put simply, you will get thirsty.

If you are thirsty, drink water. If you are not thirsty, then you do not need to go out and purposefully drink 6-8 glasses of water a day since you will probably get all the water in your regular diet. One important caveat to remember though is that on hot summer days, your water losses from sweating go up and if you plan to spend some time out doors, having water with you is important to avoid dehydration and heat stroke. While the thirst reflex is pretty reliable, it does tend to fade with age and older people are more likely to become dehydrated without realizing it. Thus, the take home message is drink water when you are thirsty, but on very hot days it might not be a bad idea to stay ahead of the curve and keep hydrated.

Tugging at metaphors

Statue of dog tugging at a rope

Christina Hendricks is a Professor of Teaching in Philosophy at the University of British Columbia-Vancouver. In this post she reflects on a session run by fellow Canadian and open educator, Dave Cormier, in which he discussed ‘messy’ situations where we’re not sure what should be done.

The solution suggested seems to be to ‘tug’ things in a particular direction based on your values. I’d argue for a different, more systemic approach, given what I’ve learned so far through my MSc. What you need when confronted with a messy, problematic situation are boundaries, holistic thinking, and multiple perspectives.

I really appreciated where Dave landed in his presentation: rather than only feeling stuck, suspended, we can consult our values and make a move based on those, we can tug the rope in a tug of war in the direction of our values and work to move things from there. The focus on values is key here: ask yourself what are your values as they relate to this situation, and make decisions and act based on those, knowing that’s enough in uncertain situations. Which doesn’t mean, of course, that you can’t revisit your values and how they apply to the situation if either of those things changes, but that it’s a landing place and it’s solid enough for the moment. He talked about how we can have conversations with students and others about why we would do something in a particular situation, rather than what the right answer is, focusing on the values that are moving us.

To do so requires that we are clear about what our values are, which is in some cases more easily said than done. This is something near and dear to my heart as a philosopher, as trying to distill what is underlying our views and our decisions, what kinds of reasons and values, is part of our bread and butter.

[…]

[W]hat if we thought about complex issues and structures more like flexible webs? (Which is an image that reminds me of other of Dave Cormier’s work such as that on rhizomatic learning.) So that if you tug on one part it can still move and the other parts will move as well (or break I suppose, which in some cases may not be a bad thing).

You don't need permission, you need advice

Pedestrian crossing signal showing green person

Deciding that you want to do something and then asking for advice is different to asking for permission. In general, permission-seeking behaviour in adults is a sign of weakness, even in hierarchical organisations. It’s either a sign of personal weakness, or if there are consequences for acting with authority in your domain of influence, then it’s a sign of organisational weakness.

One of the most common anti-patterns I see that can create conflict in an otherwise collaborative environment is people asking for permission instead of advice. This is such an insidious practice that it not only sounds reasonable, it actually sounds like the right thing to do: “Hey, I was thinking about doing X, would you be on board with that?”

Advice… is easy. “Hey, I was thinking about doing X, what advice would you give me on that?” In this instance you are showing a lot of respect to the person you are asking but not saddling them with responsibility because the decision is still on you. Your obvious goal with this approach is to do the best you can, so they are going to trust you aren’t hiding any gritty details and therefore aren’t going to waste time second guessing your premises. They are going to feel comfortable giving you all their honest feedback knowing the responsibility lies with you, and your ego will remain intact because you invited the criticism on yourself directly.

Give readers a break

Illustration of a book, hand, pen, and tape measure

I recently struggled with the middle of a book which I really wanted to finish by an author I really like. The chapters were too long for its subject matter, and I gave up.

Contrast that with The Road which is quite the harrowing read at times but, as this article points out, doesn’t have any chapters at all. I completed that without any problem. Other books, like the Reacher series, have quite short chapters. The trick, it seems, is to have chapter, or at least some kind of gaps to give readers a break, at times which are appropriate.

With our phones offering us immediate dopamine, books now have to work harder to keep us engaged. ‘Busy-ness’ has become an increasing distraction, through work and parenting as well as social media. That’s why you may have noticed shorter chapters in more recent books, especially ones aimed at readers of millennial age and below (that’s pretty much everyone under forty).

As any writer will find, however, there is no magic button when it comes to chapter length: the ‘right’ one is a blend for each novel being written. There’s no point in worrying about the length of your piece of string if the string itself isn’t useful or compelling.

14kB

Close up of green leaf

It’s been four years since I switched to the Susty theme for my WordPress-powered blog. Not long later, I also redesigned my home page to be less than 1kB (although it’s slightly more than that now).

Micro.blog, which I use to host Thought Shrapnel is terrible in this regard. Using Cloudflare’s URL Scan gave a ‘bytes transferred’ total of 12.24MB, which is 3,000 times larger than the 4.15kB for my home page, and 14 times larger than the 891.28kB (including images) for my WordPress-powered blog.

Minimising the size of your site is is not only a good idea from a sustainability point of view, but having a fast-loading website is just better for user experience and SEO. The extract below explains why having a site that is less than 14KB (compressed) is a good idea from a technical perspective.

Most web servers TCP slow start algorithm starts by sending 10 TCP packets.

The maximum size of a TCP packet is 1500 bytes.

This maximum is not set by the TCP specification, it comes from the ethernet standard

Each TCP packet uses 40 bytes in its header — 16 bytes for IP and an additional 24 bytes for TCP

That leaves 1460 bytes per TCP packet. 10 x 1460 = 14600 bytes or roughly 14kB!

So if you can fit your website — or the critical parts of it — into 14kB, you can save visitors a lot of time — the time it takes for one round trip between them and your website’s server.

Doing things that don’t scale in pursuit of things that can’t scale

Note: I’ve been away from here for just over a month, and my backlog is so huge that I can’t put off posting any longer!

Illustration of knitting (hands, needles, wool)

I’ve said many times over the last few years to friends and family that I’ve achieved all that I want to in life. That, I think, makes it easier to ‘pursue things that don’t scale’ — but so does studying philosophy from my teenage years onwards.

This post talks about “doing things that don’t scale in pursuit of things that can’t scale” which is a great way of saying doing things that are human-scale. One of the examples given in this post is knitting, which cited in an article in The Guardian as being an example of the kinds of arts and crafts that promote wellbeing.

To some extent, of course, all of this is borne of maturity, of life experience, and of approaching and then reaching middle-age.

Chasing scale seems to be a kind of early life affliction. The more you chase it, the bigger the thing you chase gets. Perhaps it’s a natural desire to see how important we can be or at least how important our creations can be to the world (and hence how important we can be by proxy …). A desire to take on a seemingly insurmountable challenge, perhaps a noble one (though not always), and see if we can conquer it.

Yet without limits, we try to find them. This is true on many levels, whether it’s about how big we want our creations to become or how people should be able to lead their personal lives or how much candy kids can eat after a Halloween haul. But I think having no limits is unnatural. Chasing scale to the level we do is too. Whether we succeed or not, it stresses the system and inevitably burns us out.

Then a new motivation seems to surface, a desire to pursue something that can’t scale. See, my theory is that chasing things that scale makes you need therapy, and the therapy is pursuing things that can’t scale. The antidote to burnout and the existential inquiry it brings seems to be doing things that don’t scale in pursuit of things that can’t scale. It becomes exciting not to see what you can do without limits, but to see what you can do with them.

What are these pursuits that can’t scale? They could be skills, like archery or chess or cooking. They could be close relationships, like making friends. Maybe it’s building a truckload of IKEA furniture. Or maybe it’s starting a local small business. These pursuits could be considered hobbies or something more serious. It doesn’t matter so much what it is than that it has a clear and visible ceiling.

Stand up for yourself. Challenge authority. Tell your rude co-worker to shut up.

Office environment with magnifying glass over one desk

I can’t say I’ve ever read Roxanne Gay’s Work Friend column for The New York Times during the last four years, but I enjoyed reading her sign-off article. She talks about the advice she really wanted to give people (usually “quit your job”) and the things that we really want, but will never be able to get, from a job.

To work, for so many of us, is to want, want, want. To want to be happy at work. To feel useful and respected. To grow professionally and fulfill your ambitions. To be recognized as leaders. To be able to share what you believe with the people you’re around for eight or more hours a day. To be loyal and hope your employers will reciprocate. To be compensated fairly. To take time off to recharge and enjoy the fruits of your labor. To conquer the world. To do a good enough job and coast through middle age to retirement.

[…]

We shouldn’t have to suffer or work several jobs or tolerate intolerable conditions just to eke out a living, but a great many of us do just that. We feel trapped and helpless and sometimes desperate. We tolerate the intolerable because there is no choice. We ask questions for which we already know the answers because change is terrifying and we can’t really afford to risk the loss of income when rent is due and health insurance is tied to employment and someday we will have to stop working and will still have financial obligations.

I was mindful of these realities as I answered your Work Friend questions. Still, in my heart of hearts, I always wanted to tell you to quit your job. Negotiate for the salary you deserve. Stand up for yourself. Challenge authority. Tell your rude co-worker to shut up. Report your boss to everyone and anyone who will listen. Consult a lawyer. Did I mention quit your job? Go back to graduate school. Leave some deodorant and mouthwash on your smelly co-worker’s desk. Send that angry email to your undermining colleague. Call out your boss when he makes a wildly inappropriate comment. No, your boss should not force you to work out of her kitchen. Mind your own business about your colleague’s weird hobby. Mind your own business, in general. Blow the damn whistle on your employer’s cutting corners and putting people’s lives in danger. Tell the irresponsible dog owner to learn how to properly care for the dog. No, you don’t owe your employer anything beyond doing your job well in exchange for compensation. No, your company is not your family. No, the job will never, ever love you.

This is all to say that I wish we lived in a world where I could offer you frank, unfiltered professional advice, but I know we do not live in such a world.

You don't have to like what other people like, or do what other people do

Orange text on yellow background: 'Why don't you just switch off your television set and go and do something less boring instead...?'

Warren Ellis responds to a post by Jay Springett on ‘surface flatness’ by reframing the problem as… not one we have to worry about. It’s good advice: so long as you can sustain an income by not having to interact with online walled gardens, why care what other people do?

(I’m saying this slightly hesitantly, as I often do hand-wringing about the amount of disinformation on mainstream social networks and chat apps, but there’s not much I personally can do about it)

If you treat all those internet platforms as television, then you can turn them off and go for a walk on the internet instead. Structured hypertext products are still walled gardens, they’re just themed gardens, like a physic garden. The thing about walled gardens is that most people like them. They’re easy.

Jay has a point about the big platforms generally deprecating a lot of hypertext functions, as they lead people out of the walled gardens. But people like walled gardens. Even if they’re full of toxic plants, stinking blooms and corpse flowers. And besides: you have no more hope of imposing a new way of doing things on the internet than of preventing the BBC from commissioning any new programme with Michael McIntyre in it.

Leave ’em to it. Network tv isn’t all of broadcast culture, just as the big platforms aren’t all of internet culture, and all that shit is still hyperlinked. Leave the platforms to it. Go for a walk and report your notes.

Summer digital detox

iPad, coffee, and leaf on a white surface

During my run yesterday morning, I listened to a great podcast episode about doing different things during the summer months. Now, as I wait to pick up my daughter from school in the driving rain it might not feel like summer here in the UK, but the advice is nonetheless spot-on.

In particular, I’ve taken the advice to do a bit of a digital detox and slow down a bit. So I’ve logged out of my Mastodon, Bluesky, and LinkedIn accounts, and will be back… mañana.

The summer months have a different flavour and feel to the other months of the year; there’s something different about our energy, motivation and willpower. And, if we can harness those differences, we have a golden opportunity to make meaningful changes that can have a transformative impact on our health, happiness and relationships and teach us things about ourselves that we previously did not know.

Informatics of domination

Part of the Calculating Empires map

I’ve had this incredible interactive map, created by Kate Crawford and Vladan Joler, bookmarked for a while now. I’m never sure what to do with so much information in one place that isn’t primarily text-based.

I’m sharing it while still exploring it myself, with the hope that others will be able to find a use for it rather than be overwhelmed!

Calculating Empires is a large-scale research visualization exploring how technical and social structures co-evolved over five centuries. The aim is to view the contemporary period in a longer trajectory of ideas, devices, infrastructures, and systems of power. It traces technological patterns of colonialism, militarization, automation, and enclosure since 1500 to show how these forces still subjugate and how they might be unwound. By tracking these imperial pathways, Calculating Empires offers a means of seeing our technological present in a deeper historical context. And by investigating how past empires have calculated, we can see how they created the conditions of empire today.

[…]

Calculating Empires takes Donna Haraway’s provocation literally that we need to map the “informatics of domination.” The technologies of today are the latest manifestations of a long line of entangled systems of knowledge and control. This is the purpose of our visual genealogy: to show the complex interplay of systems of power, information, and circumstance across terrain and time, in order to imagine how things could be otherwise.

This work can never be complete: it is necessarily partial, subjective, and drawn from our own positionality. But that openness is part of the project. You are invited to read, reflect, and consider your own history in the recurring stories of calculation and empire. As the overwhelming now continues to unfold, Calculating Empires offers the possibility of looking back, in order to consider how different futures could be envisioned and realized.

If you're not a part of the solution, there's good money to be made in prolonging the problem

Open-plan office with wooden tables, string lights, and people working at computers.

There’s a lot of money sloshing around at the top of society, being channeled into different schemes and offshore bank accounts. To enable this, there are a lot of bullshit jobs, including PR agencies spewing out credulous content.

Joan Westenberg was one of these people, until one day, she decided not to be. As she quotes Upton Sinclair as saying, “It is difficult to get a man to understand something when his salary depends upon his not understanding it.”

One morning, I sat down at my desk to craft yet another press release touting yet another “game-changing” startup that had raised - yet another - $25 million. And I realized I couldn’t remember the last time I’d written something I believed in. The words that used to flow felt like trying to squeeze ancient toothpaste from an empty tube.

That was the day I cracked.

It wasn’t about the individual startups or the overhyped products. It was the whole damn ecosystem—if we can call it that. The inflated valuations, cult-like frat house “culture,” and the relentless, mindless pursuit of growth that comfortably glossed over the human cost of “disruption.”

Somewhere along the way, I’d allowed my writing—the thing that used to give me purpose—to be co-opted by the bullshit industrial complex. I’d convinced myself that I was part of something bigger, something world-changing. But deep down, in the quiet moments between pitch meetings and product launches, I knew better.

Look out for surplus fingers

Montage of still from AI-generated (or modified) videos with the word 'FAKE' over the top

As I always say about misinformation and disinformation: people believe what they want to believe. So you don’t actually need very sophisticated ‘deepfakes’ for people to reshare fake content.

That being said, this article in The Guardian does a decent job of showing some ways of spotting deepfake content, along with some examples.

Look out for surplus fingers, compare mannerisms with real recordings and apply good old-fashioned common sense and scepticism, experts advise

In a crucial election year for the world, with the UK, US and France among the countries going to the polls, disinformation is swirling around social media.

There is much concern about deepfakes, or artificial intelligence-generated images or audio of leading political figures designed to mislead voters, and whether they will affect results.

They have not been a huge feature of the UK election so far, but there has been a steady supply of examples from around the world, including in the US where a presidential election looms.

Here are the visual elements to look out for.

New materials for a super-heated world

A floating white fabric over a colorfully edited aerial view of an urban area with green buildings.

As I mentioned I’m reading Lifehouse by Adam Greenfield at the moment, which starts with some stark information about global heating. We need lots of workarounds to combat this, and some new material looks particularly promising.

This new textile could provide at least a little relief. It uses a process called radiative cooling, which describes how objects cool down by radiating thermal energy into their surroundings. Radiative cooling textiles do already exist, but most just reflect the sun’s heat. That “works very well if you’re in an open field,” says Po-Chun Hsu, a molecular engineering professor at the University of Chicago, whose team recently published a paper on their new material in the journal Science. But not in a city.

What those other fabrics don’t do is reflect the ambient heat coming from the street below or a nearby building. The heat coming directly from the sun’s rays and the heat emitted from a sun-baked street aren’t the same; they have different wavelengths. That means a material has to have two different “optical properties” to reflect both.

To do that, the researchers created a three-layer textile. The top layer is made of polymethylpentene or PMP, a type of plastic commonly used for packaging; the researchers had to figure out how to spin it into a fiber. The second is a sheet of silver nanowires, which acts like a mirror to reflect infrared radiation. Together, these block both the solar radiation and the ambient radiation reflected off of surfaces. The third layer can be any conventional fabric, like wool or cotton. Though there are multiple layers, the main thickness comes from the conventional fabric; the top layer is about 1/100th of a human hair.

In outdoor tests in Arizona, the textile stayed 4.1 degrees Fahrenheit (2.3 degrees Celsius) cooler than “broadband emitter” fabrics used for outdoor sports, and 16 F (8.9 C) cooler than regular silk, a breathable fabric often used for dresses and shirts.

Along with clothing, the researchers say this cooling textile could be used on buildings, in cars, or even for food storage and shipping in order to lessen the need for refrigeration, which has a significant climate impact of its own. Next, Hsu’s team is collaborating with other teams to see how the textile could have a health benefit for those in extreme heat conditions.

Eye-contact has a significant impact on interpersonal evaluation, and online job interviews are no exception

Two diagrams of individuals making eye-contact in video conferencing, with differences in focus on the camera and screen.

Maintaining “eye contact” with someone on a video conference call is a bit weird, because it necessitates looking directly into the camera. It’s important, though, otherwise it feels like the other person isn’t looking at you. And that impacts relationships - and, it seems, interpersonal evaluations.

The results indicate interviewers evaluate candidates more positively when their gaze is directed at the camera (i.e., CAM stimulus) compared to when the candidates look at the screen (SKW stimulus). The skewed-gaze stimulus received worse evaluation scores than voice-only presentation (VO stimulus).

Throughout an online interview, it is challenging to maintain “genuine” eye contact—making direct and meaningful visual connection with another person, but gazing into the camera can accomplish a similar feeling online as direct eye contact does in person.

While the evaluators overall preferred interviewees who maintained eye contact with the camera, an unconscious gender bias appeared. Female evaluators judged those with skewed downward gazes more harshly than male evaluators, and the difference in the evaluation of the CAM and SKW stimuli for female interviewees was larger than the male interviewees.

This gender bias within the study could be prevalent under non-experimental conditions. Making both interviewers and interviewees aware of this potentially systematic gender bias could help curtail this issue.

Adam generously featured on an episode during the last season of our podcast, The Tao of WAO and was generous with his time. Go and listen to that to discover what the book’s original title was, and also pre-order the book!

I have a particular suspicion of the kind of book that spends 10 chapters telling the reader the many problems that face the contemporary world, and then follows with a final chapter that offers something - socialism, say - as the simple solution to all our woes. I call this the ‘11 Chapter problem’, and warn every author to avoid this trap. It is often easy to diagnose the problem; it is far harder to think clearly about what we are meant to do about it. More often than not the reader is already well aware of the problems: the reason they pick up a book is to find solutions. And this is why I am so excited about Adam Greenfield’s Lifehouse: Taking Care of Ourselves in a World on Fire. Here is a book as a toolbox to build actual, hard-tacks answers to the crisis of the Long Emergency.

It starts as a building - a church, a library, a school gym - that is the Lifehouse. This is a place for everyone to go to in an emergency - a flood, fire, or hurricane. It will have a kitchen, beds, clothing storage. But it will also be its own power source - with generators or renewable energy from a wind turbine, or solar panels on the roof. It will also be able to produce its own food with vertical farming technology installed. It will be a tool library that allows for repair and restoration, even outside the emergency - with 3-D printing technology. It will also have a skills library so that the community knows who is a doctor, nurse, teacher or transport.

But sustaining that effort for the long term - the long emergency itself - is hard. Often communities fail to plan far enough ahead. They split and betray each other. They face insurmountable opposition who wish to take away their autonomy. The Lifehouse is designed with this in mind too. It is not an afterthought, but a deeply considered means in which to think about the future.
