We continue to revisit the issue of motivation and specifically, the “carrot and stick” aspect.  New research seems to indicate that brain chemicals may control behavior and for people to learn and adapt in the world; therefore, both punishment and reward may be necessary. T

The real question is, which route would you choose—positive or negative? Most people are taught to refrain from engaging in a certain behavior by being given punishments that create negative feelings.

Different players use different strategies. It all depends on their genetic material. People's tendency to change their choice immediately after receiving a punishment depends on which serotonin gene variant they inherited from their parents. The dopamine gene variant, on the other hand, exerts influence on whether people can stop themselves making the choice that was previously rewarded, but no longer is

Ah, the tyranny of read receipts – enough to put you off digital communication for good.

It sounds straightforward enough, even perfunctory, and indeed it is if it’s only a blip in the back-and-forth. But when a message lingers on “seen” without explanation for anything beyond a few minutes, you’ve been “left on read”. It’s enough to make even the most self-assured individuals question their worth.

It works both ways, too: if you’ve read a message that you’re either unable or unwilling to respond to immediately, the countdown has already started.

I emailed Tinder requesting my personal data and got back way more than I bargained for. Some 800 pages came back containing information such as my Facebook “likes”, my photos from Instagram (even after I deleted the associated account), my education, the age-rank of men I was interested in, how many times I connected, when and where every online conversation with every single one of my matches happened … the list goes on.

“You are lured into giving away all this information,” says Luke Stark, a digital technology sociologist at Dartmouth University. “Apps such as Tinder are taking advantage of a simple emotional phenomenon; we can’t feel data. This is why seeing everything printed strikes you. We are physical creatures. We need materiality.”

What will happen if this treasure trove of data gets hacked, is made public or simply bought by another company? I can almost feel the shame I would experience. The thought that, before sending me these 800 pages, someone at Tinder might have read them already makes me cringe.

Confirmation bias is one of the most widely discussed epistemically problematic cognitions, challenging reliable belief formation and the correction of inaccurate views. Given its problematic nature, it remains unclear why the bias evolved and is still with us today. To offer an explanation, several philosophers and scientists have argued that the bias is in fact adaptive. I critically discuss three recent proposals of this kind before developing a novel alternative, what I call the ‘reality-matching account’

Confirmation bias is typically viewed as an epistemically pernicious tendency. For instance, Mercier and Sperber (2017: 215) maintain that the bias impedes the formation of well-founded beliefs, reduces people’s ability to correct their mistaken views, and makes them, when they reason on their own, “become overconfident” (Mercier 2016: 110).

Human beings often act in irrational and unexpected ways when it comes to business decisions, money, and finance.

Behavioral finance tries to explain the difference between what economic theory predicts people will do and what they actually do in the heat of the moment. 

There are two main types of biases that people commit causing them to deviate from rational decision-making: cognitive and emotional.

“Study: 70% of Facebook users only read the headline of science stories before commenting” – the fake news website the Science Post has racked up a healthy 127,000 shares for the article which is almost entirely lorem ipsum filler text.

Twitter’s solution is not to ban such retweets, but to inject “friction” into the process, in order to try to nudge some users into rethinking their actions on the social network.

In May, the company began experimenting with asking users to “revise” their replies if they were about to send tweets with “harmful language” to other people.

Impossible Colors and How to See Them

How Impossible Colors Work Basically, the human eye has three types of cone cells that register color that work in an antagonistic fashion:Blue versus yellowRed versus greenLight versus darkThere is overlap between the wavelengths of light covered by the cone cells, so you see more than just blue, yellow, red, and green. White, for example, is not a wavelength of light, yet the human eye perceives it as a mixture of different spectral colors. Because of the opponent process, you can't see both blue and yellow at the same time, nor red and green. These combinations are so-called impossible colors.

The US secretary of state, Mike Pompeo, has said Washington and its allies were seeking a “peaceful resolution” with Iran in the wake of the attack on Saudi oil facilities, making clear that Washington would limit its initial response to further sanctions.

“I was here in an act of diplomacy. While the foreign minister of Iran is threatening all-out war and to fight to the last American, we’re here to build out a coalition aimed at achieving peace and a peaceful resolution to this,”

“US inaction will be perceived as weakness,” said Suzanne Maloney, deputy director of the foreign policy programme at the Brookings Institution. “Let me be clear: I’m not advocating war. The point is that [Trump] engaged in a stupid, unnecessary, incredibly dangerous bluff and the Iranians have called him on it.”

Bangladesh is one of dozens of countries on the frontline of the climate emergency. Here global heating is no theoretical calamity of the future, but a very real, present danger.By 2050, it is predicted that one in seven people in the country will be displaced by climate breakdown. The sea level is projected to rise by 50cm over this time period and Bangladesh may lose approximately 11% of its land. Deadly storms are usually a question of when, not if.

For example, Mondal says that where once his peers would farm mainly rice, now they have taken to fishing. They use floating cages, allowing fish to breed in a secure area. Also, if water levels rise, the cages will too, so flooding is less of an issue.“About 20 to 30 years ago there would be a minimum of two crops per farming family but now because of waterlogging we have no more than one,” he says. Each cage is owned by one home and yields about 15,000 taka (£135) in additional income for the families a year. It’s also a consistent source of food, which could be vital if natural disaster hits. “In the last two years there was not too much rain but two years ago we were flooded,” Mondal says. “We worry about the future. If there is heavy rainfall the water could remain logged for a long period of time and we would have to take shelter on main road. We would stay there with our remaining belongings.”

I understand why scientifically minded people experience profound frustration at the nonsense, particularly when we’re forced to consider the public health implications of the anti-vaxxer movement which has been blamed as the root cause for recent outbreaks of measles in the US, a viral infection which can prove devastating for babies and young children. Misinformation can cause immense suffering and we should do our utmost to dispel the lies.

Too many people in scientific spheres seem to revel in dismissing flat-Earthers and anti-vaxxers as garden variety nut-jobs and losers. It may be cathartic – but it’s not productive.

It’s interesting that for a scientific community so perennially pleased with itself, we all seem to be making the same fundamental attribution error by ignoring the notion that belief in pseudoscience and conspiracy theories is propelled by external pressures of fear, confusion and disempowerment. Instead we seem too often satisfied with pinning the nonsense on some bizarrely flourishing individual idiocy.

Martin Hairer, an Austrian-British researcher at Imperial College London, is the winner of the 2021 Breakthrough prize for mathematics, an annual $3m (£2.3m) award that has come to rival the Nobels in terms of kudos and prestige.

Hairer landed the prize for his work on stochastic analysis, a field that describes how random effects turn the maths of things like stirring a cup of tea, the growth of a forest fire, or the spread of a water droplet that has fallen on a tissue into a fiendishly complex problem.

His major work, a 180-page treatise that introduced the world to “regularity structures”, so stunned his colleagues that one suggested it must have been transmitted to Hairer by a more intelligent alien civilisation.

Countries that allow economic inequality to increase as they grow richer make their citizens less happy, a new study shows.

Until now, researchers have believed that inequality was largely irrelevant to levels of life satisfaction,

his study of 78 countries spanning four decades – the largest longitudinal research of its kind – punctures that myth

Had the doctoring been done by someone from the insurer, as Ariely implied? There didn’t seem to be a way to dispute that contention, and the company itself wasn’t saying much. Then, last week, NPR’s Planet Money delivered a scoop: The company, called The Hartford, informed the show that it had finally tracked down the raw numbers that were provided to Ariely—and that the data had been “manipulated inappropriately” in the published study.

The analysis of insurance data from The Hartford appeared as “Experiment 3” in the paper. On the preceding page, an analysis of a different dataset—the one linked to Gino—was written up as “Experiment 1.” The scientists who say they discovered issues with both experiments—Leif Nelson, Uri Simonsohn, and Joe Simmons—dubbed the apparent double fraud a “clusterfake.” When I spoke with the scientific-misconduct investigator and Atlantic contributor James Heathers, he had his own way of describing it: “This is some kind of mad, fraudulent unicorn.”

When they set about reviewing Ariely’s work on the 2012 paper, a few quirks in the car-insurance data tipped them off that something might be amiss. Some entries were in one font, some in another. Some were rounded to the nearest 500 or 1,000; some were not. But the detail that really caught their attention was the distribution of recorded values. With such a dataset, you’d expect to see the numbers fall in a bell curve—most entries bunched up near the mean, and the rest dispersed along the tapering extremes. But the data that Ariely said he’d gotten from the insurance company did not form a bell curve; the distribution was completely flat. Clients were just as likely to have claimed that they’d driven 1,000 miles as 10,000 or 50,000 miles. It’s “hard to know what the distribution of miles driven should look like in those data,” the scientists wrote. “It is not hard, however, to know what it should not look like.”

if all of those bad presentations really led to broad societal ills, the proof is hard to find.

Some scientists have tried to take a formal measure of the alleged PowerPoint Effect, asking whether the software really influences our ability to process information. Sebastian Kernbach, a professor of creativity and design at the University of St. Gallen, in Switzerland, has co-authored multiple reviews synthesizing this literature. On the whole, he told me, the research suggests that Tufte was partly right, partly wrong. PowerPoint doesn’t seem to make us stupid—there is no evidence of lower information retention or generalized cognitive decline, for example, among those who use it—but it does impose a set of assumptions about how information ought to be conveyed: loosely, in bullet points, and delivered by presenters to an audience of passive listeners. These assumptions have even reshaped the physical environment for the slide-deck age, Kernbach said: Seminar tables, once configured in a circle, have been bent, post-PowerPoint, into a U-shape to accommodate presenters.

When I spoke with Kernbach, he was preparing for a talk on different methods of visual thinking to a group of employees at a large governmental organization. He said he planned to use a flip chart, draw on blank slides like a white board, and perhaps even have audience members do some drawing of their own. But he was also gearing up to use regular old PowerPoint slides. Doing so, he told me, would “signal preparation and professionalism” for his audience. The organization was NASA.

AI headshots aren’t yet perfect, but they’re so close I expect we’ll start seeing them on LinkedIn, Tinder and other social profiles. Heck, we may already see them. How would we know?

Welcome to our new reality, where nothing is real. We now have photos initially captured with cameras that AI changes into something that never was

Or, like the headshot above, there are convincingly photographic images AI generates out of thin air.

Emotions, when they are not disordered, provide information about your circumstances in a simple, quick way that does not involve a lot of cognition (thinking about it).

Emotions serve a purpose, informing you, the operator of your body, what to do.

Your emotional system can give you an advantage in decision making if you make proper use of it.

thighbones to snap in two have shaken many osteoporosis patients so much that they say they would rather take their chances with the disease.

“What are the necessary social and psychological conditions that allow populists of Hitler’s ilk to gain a mass following and attain power?”

“There are certain traits you can recognize that Hitler and Trump have in common,” Ullrich says. “I would say the egomania, the total egocentricity of both men, and the inclination to mix lies and truth – that was very characteristic of Hitler.”

Like Trump, “Hitler exploited peoples’ feelings of resentment towards the ruling elite.” He also said he would make Germany great again. Ullrich also notes both men’s talent at playing the media, making use of new technology and their propensity for stage effects.

IT did not take long for the tech industry to become the new establishment, and to assign itself the rights and responsibilities that come with such prosperity.

Tech’s elite, lauded for their originality, are influencing media, politics and society at large with a kind of venture philanthropy, much as their industrial predecessors did more than 100 years ago.

The robber barons of the 19th and 20th centuries were kings of infrastructure. The people with towering wealth today are kings of information. The rise of Silicon Valley is best understood as a new industrial revolution in this tradition.
