Daniel Kahneman on 'Emergent Weirdness' in Artifical Intelligences - Alexis Madrigal - ... - 0 views

  • Human brains take shortcuts in making decisions. Finding where those shortcuts lead us to dumb places is what his life work has been all about. Artificial intelligences, say, Google, also have to take shortcuts, but they are *not* the same ones that our brains use. So, when an AI ends up in a weird place by taking a shortcut, that bias strikes us as uncannily weird. Get ready, too, because AI bias is going to start replacing human cognitive bias more and more regularly.

Right and Left React to the Paris Climate Agreement News - The New York Times - 0 views

  • The political news cycle is fast, and keeping up can be overwhelming. Trying to find differing perspectives worth your time is even harder. That’s why we have scoured the internet for political writing from the right and left that you might not have seen.
  • “Its breakthrough was not in lifting nations up to higher levels of ambition, but rather in dropping expectations to the lowest common denominator.”
  • He argues that the treaty did little to reduce emissions because of one central flaw in the agreement’s logic: the “pledge and review” process that governed international talks. “That logic relied on a misunderstanding of what motivates developing nations,” he writes.

  • “There are a few reasons that explain conservatives who were Never-Trumpers during the election, and who remain anti-Trump today. [...] They do not believe that America is engaged in a civil war, with the survival of America as we know it at stake.

  • “That means praise him when he’s right, and find the most plausible possible defense when he’s wrong.”
  • “The conservative reaction to Trump’s Paris decision really drove home how this is all — and I do mean all — about waging culture war against the left.”
  • Rather than seeing the science in “pragmatic terms,” the president and the G.O.P. have made the issue into a “tribal struggle.” The cost of the right’s “desire to piss off lefty tree-huggers,” however, is an uncertain future for our grandchildren.
  • “A man who wished to become the most powerful man in the world [...] was granted his wish. Surely he must have imagined that more power meant more flattery, a grander image, a greater hall of mirrors reflecting back his magnificence. But he misunderstood power and prominence.”
  • “When it comes to decisions about strangers, the easiest, most accessible shortcut is our first impression. Unknowledgeable voters go for this shortcut.”

Looking inward in an era of 'fake news': Addressing cognitive bias | YLAI Network - 0 views

  • In an era when everyone seems eager to point out instances of “fake news,” it is easy to forget that knowing how we make sense of the news is as important as knowing how to spot incorrect or biased content
  • While the ability to analyze the credibility of a source and the veracity of its content remains an essential and often-discussed aspect of news literacy, it is equally important to understand how we as news consumers engage with and react to the information we find online, in our feeds, and on our apps
  • People process information they receive from the news in the same way they process all information around them — in the shortest, quickest way possible
  • ...11 more annotations...
  • When we consider how we engage with the news, some shortcuts we may want to pay close attention to, and reflect carefully on, are cognitive biases.
  • In fact, without these heuristics, it would be impossible for us to process all the information we receive daily. However, the use of these shortcuts can lead to “blind spots,” or unintentional ways we respond to information that can have negative consequences for how we engage with, digest, and share the information we encounter
  • These shortcuts, also called heuristics, streamline our problem-solving process and help us make relatively quick decisions.
  • Confirmation bias is the tendency to seek out and value information that confirms our pre-existing beliefs while discarding information that proves our ideas wrong.
  • Cognitive biases are best described as glitches in how we process information
  • Echo chamber effect refers to a situation in which we are primarily exposed to information, people, events, and ideas that already align with our point of view.
  • Anchoring bias, also known as “anchoring,” refers to people’s tendency to consider the first piece of information they receive about a topic as the most reliable
  • The framing effect is what happens when we make decisions based on how information is presented or discussed, rather than its actual substance.
  • Fluency heuristic occurs when a piece of information is deemed more valuable because it is easier to process or recall
  • Everyone operates under one or more cognitive biases. So, when searching for and reading the news (or other information), it is important to be aware of how these biases might shape how we make sense of this information.
  • In conclusion, we may not be able to control the content of the news — whether it is fake, reliable, or somewhere in between — but we can learn to be aware of how we respond to it and adjust our evaluations of the news accordingly.

The Downward Slide of the Seesaw - The New York Times - 0 views

  • The older seesaws were wooden planks that often hit asphalt directly, leading to occasional tailbone and spinal injuries, falls and pinched fingers, not to mention splinters. Children could slam each other by dismounting suddenly. Playgrounds that retained old seesaws were exposed to lawsuits.
  • “I think we have to take the kids out a little bit from the safety bubble,” she said, placing her 2-year-old daughter, Sadie, on a seesaw too.
  • “One little fall or a tooth broken and the next thing you know they are out,” she said.
  • ...3 more annotations...
  • As a result, relatively few playground injuries are now attributable to seesaws. According to data collected by the United States Consumer Product Safety Commission, which sets the safety standards, the top three pieces of equipment associated with emergency room visits between 2009 and 2014 were monkey bars, swings and slides. Only 2 percent of injuries were from teeter-totters.
  • “A seemingly simple plaything actually provides so many important sensory experiences for kids,” she said.
  • “The more we live with the safety standards, the more you see people kind of innovating to bring back types of experiences that maybe for a while you weren’t seeing,” she said. “There’s no reason to think we won’t have traditional seesaws in the park at some point.”
  •  
    This article mentioned a conflict between safety and experience. Can we be both safe and get the experience of overcoming difficulty? Obviously, we have to sacrifice one thing to get another. I think removing the seesaw is not a good idea if we just do it out of the concern of safety. We can never stay in our comfort zoom because once we grow up, we won't have our parents to protect us every time. Something related to TOK is that our mental shortcut of avoiding danger may not always benefit us. --Sissi (12/14/2016)

Fake Academe, Looking Much Like the Real Thing - The New York Times - 0 views

  • Academics need to publish in order to advance professionally, get better jobs or secure tenure.
  •  
    Academe is losing its meaning now because the society only sees how many journals you have published but not what you actually write in the journals. I think the growing business of academic publication fraud reflects that our society values our certificates more than our skills. The numerous articles on those "good" colleges also put pressure on teenagers and parent that a title means all. However, that shouldn't be core of education. There is never a shortcut to success. --Sissi (12/31/2016)

Research Shows That the Smarter People Are, the More Susceptible They Are to Cognitive ... - 0 views

  • While philosophers, economists, and social scientists had assumed for centuries that human beings are rational agents—reason was our Promethean gift—Kahneman, the late Amos Tversky, and others, including Shane Frederick (who developed the bat-and-ball question), demonstrated that we’re not nearly as rational as we like to believe.
  • When people face an uncertain situation, they don’t carefully evaluate the information or look up relevant statistics. Instead, their decisions depend on a long list of mental shortcuts, which often lead them to make foolish decisions.
  • in many instances, smarter people are more vulnerable to these thinking errors. Although we assume that intelligence is a buffer against bias—that’s why those with higher S.A.T. scores think they are less prone to these universal thinking mistakes—it can actually be a subtle curse.
  • ...7 more annotations...
  • they wanted to understand how these biases correlated with human intelligence.
  • self-awareness was not particularly useful: as the scientists note, “people who were aware of their own biases were not better able to overcome them.”
  • Perhaps our most dangerous bias is that we naturally assume that everyone else is more susceptible to thinking errors, a tendency known as the “bias blind spot.”
  • This “meta-bias” is rooted in our ability to spot systematic mistakes in the decisions of others—we excel at noticing the flaws of friends—and inability to spot those same mistakes in ourselves.
  • it applies to every single bias under consideration, from anchoring to so-called “framing effects.” In each instance, we readily forgive our own minds but look harshly upon the minds of other people.
  • intelligence seems to make things worse.
  • the driving forces behind biases—the root causes of our irrationality—are largely unconscious, which means they remain invisible to self-analysis and impermeable to intelligence. In fact, introspection can actually compound the error, blinding us to those primal processes responsible for many of our everyday failings. We spin eloquent stories, but these stories miss the point. The more we attempt to know ourselves, the less we actually understand.

Your brain thinks - but how? - 0 views

  • “Look! Up in the sky! It’s a bird!” “It’s a plane!” “It’s Superman!”It’s the same object, the same sky. It’s even the same roar. So why do three people witnessing the same event reach different conclusions?
  • The answer to this question lies in how our brains are hardwired to think. We experience and interpret the world around us based on what we already know, even though sometimes what we know is flawed.
  • However, they cannot, because it is too impractical.
  • ...6 more annotations...
  • You must immediately know to cross a road quickly – even run – when you hear a car rapidly approaching.
  • These limitations represent a thinking problem: Our brains simply do not have enough resources to understand the world without taking some mental shortcuts.
  • Our brains find shortcuts to overcome the thinking problem by relying on thoughts already stored in our minds, called schemas. Schemas do the processing for the brain, like auto-fill, but for thinking.
  • Schemas are the building blocks of our knowledge about the world. Our brains rely on different types of schemas to understand different types of situations.
  • When our brains try to understand unfamiliar objects, they must rely on a schema for a different but similar object because the correct schema is unavailable. If the object and chosen schema closely match, our brains effortlessly – but inaccurately – assume the two objects are the same.
  • A person who has never seen a bat might assume a bat is a bird because the features of the bat and their schema for a bird are similar: Both are small animals with wings and can fly. Our brains accept occasional inaccuracies.

Cognitive Bias: Understanding How It Affects Your Decisions - 0 views

  • A cognitive bias is a flaw in your reasoning that leads you to misinterpret information from the world around you and to come to an inaccurate conclusion. Because you are flooded with information from millions of sources throughout the day, your brain develops ranking systems to decide which information deserves your attention and which information is important enough to store in memory. It also creates shortcuts meant to cut down on the time it takes for you to process information. The problem is that the shortcuts and ranking systems aren’t always perfectly objective because their architecture is uniquely adapted to your life experiences
  • Anchoring bias is the tendency to rely heavily on the first information you learn when you are evaluating something. In other words, what you learn early in an investigation often has a greater impact on your judgment than information you learn later. In one study, for example, researchers gave two groups of study participants some written background information about a person in a photograph. Then they asked them to describe how they thought the people in the photos were feeling. People who read more negative background information tended to infer more negative feelings, and people who read positive background information tended to infer more positive feelings. Their first impressions heavily influenced their ability to infer emotions in others.
  • Another common bias is the tendency to give greater credence to ideas that come to mind easily. If you can immediately think of several facts that support a judgment, you may be inclined to think that judgment is correct. For example, if a person sees multiple headlines about shark attacks in a coastal area, that person might form a belief that the risk of shark attacks is higher than it is.The American Psychological Association points out that when information is readily available around you, you’re more likely to remember it. Information that is easy to access in your memory seems more reliable.

Opinion | Do heuristics help us make good decisions in uncertain times? - 0 views

  • Do heuristics, the shortcuts that the brain takes, support efficient decision making or does it impede efficient decision making?
  • Humans have neither unlimited resources nor unlimited time to take decisions. So, the brain has always developed smart heuristics, shortcuts to take efficient decisions.
  • One other key thought put forward by Gigerenzer is that there is a big difference between risk and uncertainty. We are dealing with risk when you know all the alternatives, outcomes and their probabilities. We are dealing with uncertainty when you don’t know all the alternatives, outcomes or their probabilities.
  • ...1 more annotation...
  • It has been found that if doctors are trained how to translate conditional probabilities into natural frequencies, the ability of the doctors to communicate the risk to their patients goes up dramatically. Just imagine the huge difference this can make to customer satisfaction in the healthcare business.

10 Common Flaws With How We Think - 0 views

  • By nature, human beings are illogical and irrational.
  • survival meant thinking quickly, not methodically. Making a life-saving decision was more important than making a 100% accurate one, so the human brain developed an array of mental shortcuts.
  • "Our decisions... are guided by the perceived values at the moment of the decision - not by the potential final value."
  • ...6 more annotations...
  • We can never totally escape them, but we can be more aware of them, and, just maybe, take efforts to minimize their influence.
  • these shortcuts -- called cognitive biases or heuristics -- are numerous and innate.
  • we are biased against actions that could lead to regret
  • The halo effect is a cognitive bias in which we judge a person's character based upon our rapid, and often oversimplified, impressions of him or her.
  • Confirmation bias is the tendency of people to favor information that confirms their beliefs.
  • Hearing or reading information that backs our beliefs feels good, and so we often seek it out.

Recognizing Strangers | Psychology Today - 0 views

  • Benoit Monin, assistant professor of psychology at Stanford University, showed college students 80 photos of faces, then asked them which ones they recognized from among the 40 they'd seen in an earlier session. The more attractive the photo (as rated by another group of students) the more likely it was to be recognized—regardless of whether the face had been seen before.
  • "The face's attractiveness actually changes your perception of your past," in this case, the perception of whether you've seen the face before. The shortcut may lead to errors, but it may also help us manage our busy lives, says Monin. "We tend to like familiar things, so it makes perfect sense that over time we would use liking as a clue to familiarity."
  • In what he calls the "warm-glow heuristic," people consider their affinity for a specific person or place as an indicator of familiarity. As with other mental shortcuts, people resort to this heuristic when they lack enough data on which to base their decisions.
  • ...1 more annotation...
  • In a second session, he showed them an entirely new set of words and asked which words were familiar from the earlier, bogus session. Subjects were more likely to think they'd seen positive words—such as "charm" and "glory"—than either negative or neutral words that appear with the same frequency in English.

  • Just as the loss of a species decreases the richness of an ecosystem, the addition of new animals could achieve the opposite effect.
  • National Geographic Society hosted a larger conference to debate the scientific and ethical questions raised by the prospect of “de-extinction.
  • “De-extinction went from concept to potential reality right before our eyes,
  • less scientific, if more persuasive, argument was advanced by the ethicist Hank Greely and the law professor Jacob Sherkow, both of Stanford. De-extinction should be pursued, they argued in a paper published in Science, because it would be really
  • “This may be the biggest attraction and possibly the biggest benefit of de-extinction. It would surely be very cool to see a living woolly mammoth.”
  • They will replace chunks of band-tailed-pigeon DNA with synthesized chunks of passenger-pigeon DNA, until the cell’s genome matches their working passenger-pigeon genome.
  • Scientists predict that changes made by human beings to the composition of the atmosphere could kill off a quarter of the planet’s mammal species, a fifth of its reptiles and a sixth of its birds by 2050
  • This cloning method, called somatic cell nuclear transfer, can be used only on species for which we have cellular material.
  • There is a shortcut. The genome of a closely related species will have a high proportion of identical DNA, so it can serve as a blueprint, or “scaffold.”
  • By comparing the fragments of passenger-pigeon DNA with the genomes of similar species, researchers can assemble an approximation of an actual passenger-pigeon genome.
  • As with any translation, there may be errors of grammar, clumsy phrases and perhaps a few missing passages, but the book will be legible. It should, at least, tell a good story.
  • the genome will have to be inscribed into a living cell.
  • “We’ve framed it in terms of conservation,”
  • MAGE (Multiplex Automated Genome Engineering). MAGE is nicknamed the “evolution machine” because it can introduce the equivalent of millions of years of genetic mutations within minutes
  • Developmental and behavioral biologists would take over, just in time to answer some difficult questions. Chicks imitate their parents’ behavior. How do you raise a passenger pigeon without parents of its own species? And how do you train band-tailed pigeons to nurture the strange spawn that emerge from their eggs; chicks that, to them, might seem monstrous: an avian Rosemary’s Baby?
  • For endangered species with tiny populations, scientists would introduce genetic diversity to offset inbreeding.
  • They will try to alter the birds’ diets, migration habits and environment. The behavior of each subsequent generation will more closely resemble that of their genetic cousins.
  • The scientific term for this type of genetic intervention is “facilitated adaptation.”
  • “There’s always this fear that somehow, if we do it, we’re going to accidentally make something horrible, because only nature can really do it right. But nature is totally random. Nature makes monsters. Nature makes threats. Many of the things that are most threatening to us are a product of nature. Revive & Restore is not going to tip the balance in any way.”
  • This optimistic, soft-focus fantasy of de-extinction, while thrilling to Ben Novak, is disturbing to many conservation biologists, who consider it a threat to their entire discipline and even to the environmental movement.
  • The first question posed by conservationists addresses the logic of bringing back an animal whose native habitat has disappeared. Why go through all the trouble just to have the animal go extinct all over again?
  • There is also anxiety about disease
  • “If you recreate a species genetically and release it, and that genotype is based on a bird from a 100-year-old environment, you probably will increase risk.”
  • For species threatened by contagion, an effort would be made to fortify their DNA with genes that make them disease-resistant
  • De-extinction also poses a rhetorical threat to conservation biologists. The specter of extinction has been the conservation movement’s most powerful argument. What if extinction begins to be seen as a temporary inconvenience?
  • De-extinction suggests that we can technofix our way out of environmental issues generally, and that’s very, very bad.
  • How will we decide which species to resurrect?
  • Philip Seddon recently published a 10-point checklist to determine the suitability of any species for revival, taking into account causes of its extinction, possible threats it might face upon resurrection and man’s ability to destroy the species “in the event of unacceptable ecological or socioeconomic impacts.”
  • But the most visceral argument against de-extinction is animal cruelty.
  • “Is it fair to do this to these animals?” Shapiro asked. “Is ‘because we feel guilty’ a good-enough reason?” Stewart Brand made a utilitarian counterargument: “We’re going to go through some suffering, because you try a lot of times, and you get ones that don’t take. On the other hand, if you can bring bucardos back, then how many would get to live that would not have gotten to live?”
  • In “How to Permit Your Mammoth,” published in The Stanford Environmental Law Journal, Norman F. Carlin asks whether revived species should be protected by the Endangered Species Act or regulated as a genetically modified organism.
  • He concludes that revived species, “as products of human ingenuity,” should be eligible for patenting.
  • The term “de-extinction” is misleading. Passenger pigeons will not rise from the grave
  • Our understanding of the passenger pigeon’s behavior derives entirely from historical accounts.
  • There is no authoritative definition of “species.” The most widely accepted definition describes a group of organisms that can procreate with one another and produce fertile offspring, but there are many exceptions.
  • Theseus’ ship, therefore, “became a standing example among the philosophers . . . one side holding that the ship remained the same, and the other contending that it was not the same.”
  • What is coming will go well beyond the resurrection of extinct species. For millenniums, we have customized our environment, our vegetables and our animals, through breeding, fertilization and pollination. Synthetic biology offers far more sophisticated tools. The creation of novel organisms, like new animals, plants and bacteria, will transform human medicine, agriculture, energy production and much else.

I feel like this meaning is ironic. Internet is such transparent space that every big hit somehow reflect people's value and opinion. --Sissi (2/16/2017)

Strikes imply an into and through movement, which sounds nicer. Our response is physical and instinctive, just as with the up/down distinction.

Q&A: Why It's Sometimes Rational to Be Irrational - Wired Science - 0 views

  • I think it’s safe to claim that magical thinking emerges from basic underlying cognitive mechanisms — shortcuts that we take, biases, heuristics.
  • A more controversial claim, which is very possible, is that magical thinking is an exaptation. An exaptation is some adaptation that emerged as a byproduct of something else, but became so useful that evolution started to select for aspects of that in addition to the initial thing.
  • Some people have argued that belief in god probably emerged from dualism, anthropomorphism and teleological reasoning. But then it became such a useful idea on its own that now we’re evolving to have a stronger belief in god, because belief in god is evolutionarily adaptive.
  • ...4 more annotations...
  • There are a lot of dangers to magical thinking.
  • It can lead to fatalism if you think your life is completely controlled by supernatural forces.
  • But if used carefully, magical thinking can have benefits, such as a sense of control or a sense of meaning in life. So I take this somewhat paradoxical stance of using irrationality rationally.
  • eling lucky is irrational because the charm or wish itself isn’t lucky. But feeling lucky gives you a sense of control, which increases your confidence and increases your performance in various challenges. So it’s rational to hold onto that irrational belief, on some level, because it can benefit you — even if the charm can’t.

Rationally Speaking: Razoring Ockham's razor - 0 views

  • Philosophers often refer to this as the principle of economy, while scientists tend to call it parsimony. Skeptics invoke it every time they wish to dismiss out of hand claims of unusual phenomena
  • The obvious question to ask about Ockham’s razor is: why? On what basis are we justified to think that, as a matter of general practice, the simplest hypothesis is the most likely one to be true? Setting aside the surprisingly difficult task of operationally defining “simpler” in the context of scientific hypotheses (it can be done, but only in certain domains, and it ain’t straightforward), there doesn’t seem to be any particular logical or metaphysical reason to believe that the universe is a simple as it could be.
  • Pierre Duhem suggested in 1908 that, as Sober puts it: “it is wrong to think that hypothesis H makes predictions about observation O; it is the conjunction of H&A [where A is a set of auxiliary hypotheses] that issues in testable consequences.”
  • ...5 more annotations...
  • The history of science is replete with examples of simpler (“more elegant,” if you are aesthetically inclined) hypotheses that had to yield to more clumsy and complicated ones.
  • This is both why there is no such thing as a “crucial” experiment in science (you always need to repeat them under a variety of conditions), and why naive Popperian falsificationism is wrong (you can never falsify a hypothesis directly, only the H&A complex can be falsified).
  • The Duhem thesis explains why Sober is right, I think, in maintaining that the razor works (when it does) given certain background assumptions that are bound to be discipline- and problem-specific.
  • So, Ockham’s razor is a sharp but not universal tool, and needs to be wielded with the proper care due to the specific circumstances.
  • There is no shortcut for a serious investigation of the world, including the spelling out of our auxiliary, and often unexplored, hypotheses and assumptions.

The Limits of Empathy - NYTimes.com - 0 views

  • People who are empathetic are more sensitive to the perspectives and sufferings of others. They are more likely to make compassionate moral judgments.
  • The problem comes when we try to turn feeling into action. Empathy makes you more aware of other people’s suffering, but it’s not clear it actually motivates you to take moral action or prevents you from taking immoral action. In the early days of the Holocaust, Nazi prison guards sometimes wept as they mowed down Jewish women and children, but they still did it.
  • These days empathy has become a shortcut. It has become a way to experience delicious moral emotions without confronting the weaknesses in our nature that prevent us from actually acting upon them
  • ...7 more annotations...
  • “These studies suggest that empathy is not a major player when it comes to moral motivation. Its contribution is negligible in children, modest in adults, and nonexistent when costs are significant.” Other scholars have called empathy a “fragile flower,” easily crushed by self-concern.
  • empathy often leads people astray. It influences people to care more about cute victims than ugly victims. It leads to nepotism. It subverts justice; juries give lighter sentences to defendants that show sadness.
  • Empathy orients you toward moral action, but it doesn’t seem to help much when that action comes at a personal cost. You may feel a pang for the homeless guy on the other side of the street, but the odds are that you are not going to cross the street to give him a dollar.
  • It has become a way to experience the illusion of moral progress without having to do the nasty work of making moral judgments. In a culture that is inarticulate about moral categories and touchy about giving offense, teaching empathy is a safe way for schools and other institutions to seem virtuous without risking controversy or hurting anybody’s feelings.
  • People who actually perform pro-social action don’t only feel for those who are suffering, they feel compelled to act by a sense of duty. Their lives are structured by sacred codes.
  • Think of anybody you admire. They probably have some talent for fellow-feeling, but it is overshadowed by their sense of obligation to some religious, military, social or philosophic code. They would feel a sense of shame or guilt if they didn’t live up to the code. The code tells them when they deserve public admiration or dishonor.
  • The code isn’t just a set of rules. It’s a source of identity. It’s pursued with joy. It arouses the strongest emotions and attachments. Empathy is a sideshow. If you want to make the world a better place, help people debate, understand, reform, revere and enact their codes. Accept that codes conflict.

How our brain assess bargains - 0 views

  • The 'supermarket shoppers' were brain-scanned to test their reactions to promotions and special offers in a major cutting-edge project by UK-based SBXL, one of Europe's leading shopping behaviour specialists and Bangor University's respected School of Psychology.
  • We know from other research that people are not as good at making rational decisions as they might expect, often using "rules of thumb" and educated guesses to evaluate decisions. Using brain imaging techniques we hope to get a better understanding of how the brain responds to special offers and how this may influence the decisions we make. This also gives us the chance to do some research on how we make decisions in a real world context."
  • Our data also agrees with previous research suggesting that as offers, or decisions get more complex, instead of working things out, our brains take shortcuts, and may guess that an offer is good. Interestingly, in our study people were just as good at selecting good complex offers from bad as they were for less complex ones, suggesting this guessing method may be as good in some cases as "working it out"."

  • "It turns out we are not as good at picking good offers as you might expect, with the average shopper in our experiment only picking 60% of good offers compared to bad. We also found that age had a strong negative affect on the ability to choose good offers, with older people less able to choose good offers over bad ones. We find this latter effect very interesting and would like to do some more research to find out why this may be the case."
  • The advantage of using fMRI to image the brain while actively making shopping decisions is that it enables us to see how the whole brain responds, including the 'deeper' areas of the brain, such as those associated with emotion and desire. This lets us understand more about what makes an offer appealing: in some cases the choice appears to be more rational, and in other cases we can see emotional circuitry getting involved in the decision-making process".
  • In particular we are interested in how factors we are unconsciously aware of can override what might be considered the optimal choice based on conscious judgements. We hope this partnership with SBXL will lead to further research in this area."
