360 evaluation process

I mentioned this intensive anonymous co-worker survey instrument that's used, for instance, to correct bad behaviors in surgeons. 

Here are the type of questions:
Is this manager effective at solving problems?
Does this manager treat others respectfully?
Do the actions of this manager Inspire growth and development in others?
Is this manager able to resolve conflict appropriately?
Do you receive constructive and helpful feedback from this manager?
Is this manager available to provide help and feedback when you want it?
When making important decisions, does this manager consider the opinions of others?
Does this manager consistently reward employees for good performance or behavior?
Do you feel this manager sets clear direction that aligns with the organization's strategy?
Does this manager always control emotions and behavior, even when faced with high-conflict or stressful situations?

What would you say are this employee's strengths?
What is one thing this employee should start doing?
What is one thing this employee should continue doing?
What is one thing this employee should stop doing?
How well does this person manage their time and workload?
Share an example of a company value this person has brought to life.
What are three or four words you would use to describe this employee?
[For someone in a leadership role] If you were this leader, what would be the first action you would take?
How well does this person adapt to changing priorities?
What's an area you'd like to see this person improve?

Here is the website for the 360 evalutaion service. 

The unintended consequences of working from home.


This podcast discusses the evidence for working at home as opposed to the office. Working from home makes people happy and (merely 8%) more productive. But at present, employers are working hard to encourage people to return to the workplace. I would love to see the evidence for returning to work -  evidence of improved collaboration and mentoring and encountering conflicting opinions which improve productivity or creativity.

You 2.0: How to Open Your Mind | Hidden Brain podcast


... distinction between task conflict and relationship conflict... You say that one reason it's hard to admit we are wrong is that we sometimes confuse our beliefs with our values... we confuse challenges to our views with threats to our ego.
When a disagreement becomes personal, everything that gets raised by the other person is interpreted in the most negative light possible... people...don't even hear the substance of the idea because they're so invested in defending their ego or in proving the other person wrong.
... something that President Obama said some years ago when he invited someone he disagreed with to play a prominent role in his administration. President Obama: "We're not going to agree on every single issue, but what we have to do is to be able to create an atmosphere where we can disagree without being disagreeable and then focus on those things that we hold in common as Americans." 
Tony Greenwald's term... the "Totalitarian Ego." [We] have an inner dictator policing our thoughts...to keep out threatening information...when your core beliefs are attacked, the inner dictator comes in and rescues you with mental armor and activates confirmation bias where you only see what you expected to see all along, triggers desirability bias where you only see what you wanted to see all along and you can feel like you're not under threat after all.
...think of a time when [you] did something wrong and apologized for it...When you refuse to apologize it actually makes you feel more empowered, that power and control seems to translate into greater feelings of self-worth...the act of resisting influence only further fortifies our convictions, because we basically get inoculated against future attacks.
...we often spend time thinking like preachers, prosecutors, and politicians. Preaching is basically defending a set of sacred beliefs and saying, "Look, I found the truth, my job is to proselytize it." Prosecuting is the reverse. It's saying, "Okay, my job is to prove you wrong and win my case with the best argument." ...thinking like a politician [trying to] get the approval of an audience that you care about. And so you might be campaigning and lobbying and sometimes that means adjusting and flexing at least what you say you believe in order to fit in and win them over. The problem is that we're doing it because we want to prove our allegiance to a tribe not because we're trying to get closer to the truth.

[Orville and Wilbur Wright] would sometimes even shout for hours back and forth... they seemed to get a kick out of it, they called it scrapping. ...They never saw an argument as personal. Their mechanic used a phrase that I think about it almost every day. He said, "I don't think they really got mad but they sure got awfully hot."

... expert versus average negotiators... We want to build areas of consensus before we find out where we're opposed...We should think about disagreements less as wars and more as dances...You actually have to be willing to step back and let your partner lead from time to time.

...the very important idea of psychological safety - the belief that you can take a risk without being punished or penalized... psychological safety is one of the foundations of building a learning culture and making it easy for people to rethink things. Because we've seen this in studies of hospitals, for example, that when teams have psychological safety they actually admit the errors that they've made, and then everyone else can learn from them and rethink their routines and practices. Whereas if they lack psychological safety people are motivated to hide their mistakes and then they repeat them and no one else ends up rethinking the way that they're operating either.

"Solution Aversion." The idea behind solution aversion is that if you propose a way to fix a problem and people don't like your solution, they often reject not only the solution but also the problem in the first place... [One] should say, "Well, given your views about what we should do on climate policy, how would your proposed solutions work, and how would you implement them?" And when you ask those "how-questions" something really intriguing happens. Psychologists call it "The illusion of explanatory depth," and it's the idea that we think we understand complex systems much better than we actually do. And the best way to make us a little bit more intellectually humble, curious, nuanced, more doubting, less dogmatic, is to ask us to explain those various systems and their impact. 

...flexibility is a virtue, so is persistence. And I think that art much more than science is figuring out when to stay the course and when to shift gears.
"If you want to walk fast you should walk alone, but if you want to walk far you should walk together."... we spend too much of our time listening to people who think fast and shallow and not enough time paying attention to people who think slow and deep.

"Okay, I'm about to make a decision...let me take five minutes and just think about all the reasons why that plan might be wrong, not just the reasons it might be right. Let me reach out to somebody in my challenge network and ask them, 'Can you see some holes in my reasoning? Is there any way that I might regret this decision?." And that can be a quick reconsideration process.

The Unsilencing: why women get more autoimmune diseases.

"So, the pregnant person's immune system has to... downregulate [but] has to do this kind of tightrope walk. It has to take those signals from the placenta to downregulate components of [immunity]. But it also needs to...upregulate some things to be able to not die of parasites and pathogens.

So [during evolution] the human mammal and our ancestors were starting to get a placenta. And [figuring] out how to live with each other...If the placenta is going to drag down the immune system...then the mom is going to start evolving an immune system that's actually stronger...overexpressed...so that when it's dragged down, it's [reduced] to a moderate level.

...So essentially, it's all the placenta's fault. [Females] walk around with these amped up immune systems to just survive [the placenta's] presence [hence women are predisposed to] autoimmune disorders...

The Biggest Myth About Buying Local Food


"...buying your food closer is almost always better. Right?

Wrong. Let's delve a little deeper.

Proponents of local food are absolutely correct in saying that closer production reduces the carbon impact of transportation, but transportation is not the only facet of food production that releases greenhouse gases, which contribute to climate change. In fact, it's actually a pretty paltry one. Production accounts for the vast majority of agriculture's carbon footprint, while transport to the grocery store, and finally your table, accounts for less than a tenth! This value varies depending upon the foodstuff, ranging from a low of 1% for red meat to a high of 11% for fruits and vegetables.

This means that buying local really doesn't have much of an impact on climate change. In fact, in a 2008 paper, Carnegie Melon University's Christopher Weber and H. Scott Mattthews calculated that if a family reduced all of their "food miles" to zero -- basically meaning they grew all of their own food in their kitchen (good luck with that mess) -- the reduction in carbon impact would be equal to driving a 25 mile per gallon car 1,000 miles less per year. The frugal SUV driver would be making a more eco-conscious sacrifice.

Considering that production accounts for such a significant chunk of the energy that goes into food, there are actually many circumstances where buying local can actually be worse for the climate.

"For example, an acre of land in Idaho can produce about 50% more potatoes than an acre of land in Kansas," Steven Novella, president of the New England Skeptic Society, pointed out on a recent episode of The Skeptics' Guide to the Universe. Buying a local potato in this circumstance would be quite inefficient.

Moreover, for eco-conscious lamb consumers in the United Kingdom, it actually makes more sense to purchase lamb raised 11,000 miles away in New Zealand than lamb raised down the street. Why?

"New Zealand sheep are generally pastured and raised on farms using hydroelectric power," wrote Gary Adamkiewicz, an environmental scientist at Harvard." 

How does the invisible selfie stick work?


"The brand's 360º cameras have two lenses, which each capture a 200° view and are carefully positioned on the camera body so that the distance between them is sufficient to hide the selfie stick. "The algorithm stitches the two images together, using the overlap between the two images to hide the selfie stick," says Guo. "The stitching algorithm has been developed and fine-tuned over a number of years to achieve the perfect invisible selfie stick effect."

Rarest Cloud Type Finally Caught on Camera | Asperitas Clouds




Advice when shooting a time-lapse

never shoot in JPG
essential to use long shutter speeds of between 1/3 and 3s
moving plants, especially when they are in the foreground, look horrible in time-lapse.
to think that everything can be timelapsed is a big mistake.
care about framing, composition, light, and the subject
only move the camera when this movement really brings something to the shot, or at least doesn’t distract from the most important, the subject

over-retouching with aggressive process with surreal textures on buildings and dramatic skies

Not all the videos made with time-lapse must have a epic track, or use the music of the famous Icelandic band Sigur Ros

never upload your video to Youtube. The image quality...is terrible and the compression applied to the videos is very high...upload it to Vimeo, where the quality is pretty good and you will get in contact with a community of filmmakers


All good points

CO2 emissions of manufacturing and driving electric cars

Ultimately, it depends where the vehicle is made and driven, since the carbon footprint of battery production varies by how mining and electricity production are powered in each country. But bottom line, after accounting for manufacturing and driving, electric vehicles are cleaner than combustion.

Kusama: Infinity (documentary film)



Kusama: Infinity https://g.co/kgs/CsxvYt

A remarkable, provocative, innovative artist in canvas, art installations, and even performance art protests. Decades ahead of her time, she fought hard her whole life against the establishment but found her ideas constantly stolen and capitalized on by men. Even when hospitalized for her obsessive compulsions, she was nonetheless prolifically productive. Her mirrored rooms and penis-covered furniture are the perfect fodder for social media, and she finally got the recognition she deserved when almost 60 - her works and installations now garner millions. 







Storms moving slower because of climate change.

I would have expected storms to move faster with more heat and energy in the atmosphere. However, as this NYT writer mentions below,

 "The warming of the Arctic has reduced the temperature difference between it and the Equator, weakening the winds between them, in North America. That weakness, in turn, has slowed the movement of tropical storms."

"Climate change has made hurricanes wetter and slower, scientists have found. Recent research suggests that global warming — specifically in the Arctic, which is warming much more rapidly than other regions — is playing a role in weakening atmospheric circulation and thus potentially affecting hurricane speed."

How language affects how we think. Watch Your Mouth | Hidden Brain Media


"I asked Lera how describing the word chair or the word bridge as masculine or feminine changes the way that speakers of different languages think about those concepts." 

"Take the word bridge - if it's feminine in your language, you're more likely to say that bridges are beautiful and elegant. And if the word bridge is masculine in your language, you're more likely to say that bridges are strong and long and towering - these kind of more stereotypically masculine words."

"does the language that you speak matter for how you paint death, depending on whether the word death is masculine or feminine in your language? And to our surprise, 78 percent of the time, we could predict the gender of the personification based on the grammatical gender of the noun in the artist's native language."

" what he found was kids who were learning Hebrew - this is a language that has a lot of gender loading in it - figured out whether they were a boy or a girl about a year sooner than kids learning Finnish, which doesn't have a lot of gender marking in the language."

" Young people have always used language in new and different ways, and it's pretty much always driven older people crazy. All of the likes and, like, literallies (ph) might sometimes grate on your nerves, but John McWhorter says the problem might be with you, not with the way other people speak. John is a professor of English and comparative literature at Columbia University. He's also the author of the book, "Words On The Move: Why English Won't - And Can't - Sit Still (Like, Literally).""

" dictionaries in some ways paint an unrealistic portrait of a language. They give us a sense that the meanings of words are fixed, when in fact they're not."

" the evolution of words and their meanings is what gives us this flowering of hundreds or thousands of languages. Mistakes and errors are what turned Latin into French."

" there'll be slang, that there'll be new words for new things and that some of those words will probably come from other languages. But I don't think that it's always clear to us that language has to change in that things are going to come in that we're going to hear as intrusions or as irritating or as mistakes"

" in common usage, literally literally means the opposite of literally... it irritates people, but there's a different way of seeing literally. If you take literally in what we can think of as its earliest meaning, the earliest meaning known to us is by the letter. And so somebody says something literally, somebody takes a point literally. Well, if you have a word like that and if it's an intensifier of that kind, you can almost guess that literally is going to come to mean something more like just really."


" you can't know how the words are going to come out, but you can take good guesses. You know, endings are going to tend to drop off. So if you took a bunch of those tendencies, you could make up, say, the English of 50 years from now, but some of the things would just be complete chance. You would never know, for example, that - give you an example I've actually been thinking about. Women under about 30 in the United States, when they're excited or they're trying to underline a point, putting uh at the end of things. And so somebody will say, well, who was it who you thought was going to give you this present? You-uh (ph). And, I mean, really, it sounds exactly like that. I know-uh (ph) is there, or something along the lines of babe-uh (ph)."

"You  make the case that concerns over the misuse of language might actually be one of the last places where people can publicly express prejudice and class differences. And as you point out, it's not just that people feel that a word is being misused. They often feel angry about it, and you think this anger is actually telling." 

" the educated person can look down on people who say Billy and me went to the store or who are using literally, quote, unquote, "wrong" and condemn them in the kinds of terms that once were ordinary for condemning black people or women or what have you. So I just think that it's something we need to check ourselves for."

" Language is a parade, and nobody sits at a parade wishing that everybody would stand still. If the language stayed the way it was, it would be like a pressed flower in a book"

No Rabies Treatment After All: Failure of the Milwaukee Protocol – The Pandora Report

"Considering the theory that rabies pathology stems from central nervous system neurotransmitter dysfunction, doctors hypothesized suppressed brain activity would minimize damage while the patient's immune system developed an adequate response."

"[This] Milwaukee protocol, a procedure reported to prevent death after the onset of rabies symptoms, has been performed over 26 times since its inception in 2004 but has only saved one life. Overwhelming failure has led health officials to label the protocol a red herring."

Why does it rain so much at the equator?

Any time I look at the global rainfall map, there's an obvious strip of heavy rain along the equator. It's where winds spinning in opposite directions collide (because of the Coriolis effect).

"Inter Tropical Convergence Zone (ITCZ) . The ITCZ is an area of low atmospheric pressure created by the intense heat of that area. The two winds carry lot of moisture from the surrounding oceans. When the two winds converge at the ITCZ , it gets heated, becomes light and so it rises up the atmosphere. As it rises up, the air loses heat and condenses forming clouds."

Worst investment ever on Shark Tank?

Mark Cuban claims this was his worst investment ever. 
Charles Yim created a breathalyzer app "Breathometer" that the sharks invested in. "Yim became the first "Shark Tank" entrepreneur to pull in all five Sharks into a joint investment [of] $1 million investment for a 30% stake, which valued Yim's company at $3.3 million." 

He was soon seen partying it up on the TV show "Below Deck" which he claims distorted the truth of their behavior. 

Not surprisingly, the company went out of business. Yim was always partying, and a complaint by the FTC that the device wasn't accurate forced them to refund all their customers. https://www.cnbc.com/2022/07/22/mark-cuban-worst-shark-tank-investment-ever-was-breathometer.html

Japanese man who gets paid to 'do nothing'




Ok, Japanese society is just so different. It's the modern equivalent of a Geisha, in  a way. Imagine paying someone to just silently accompany you when you go shopping so you don’t feel lonely, and you would rather have a stranger than a friend you might feel obliged to talk to.

What stopsApartment Fires from Killing You?



A surprisingly well-researched and illustrated video from an amateur journalist about fire safety, emphasizing in modern high-rise building you are safer to shelter in place with fire doors closed than try to escape through smoky stairways, because of fire-resistant construction methods that keep the fire compartmentalized. 
10:53 sprinklers reduce risk of death by 80%.
The "intumescent strips" (6:52) that expand and jam the door closed sealing the fire inside are designed to deploy after any chance of saving lives has expired, meaning that you should have escaped long before the strip deploys. What does this mean for "sheltering in place" in a fire-safe building?
