Steven Castellano Proves the Stimulus Plan Will Be a Success
Steven Castellano is a senior at High Technology High School in Lincroft, New Jersey, and is one of Big Think's "10 under 25" young experts.
At High Tech, he was the vice-president of the Key Club, vice-president of the National Honor Society, and a member of the senior class council. He also served as the secretary for the New Jersey state Technology Student Association that works to promote technological literacy in schools throughout the country. He has developed a deep interest in behavioral neuroscience research throughout high school and has worked on projects investigating the effects of acupressure on alertness and visual attention skills.
His research has won first prize in the MIT THINK competition, the Delaware Valley Science Fair, the Jersey Shore Science Fair, and the New Jersey Academy of Science. In addition, Steven has been named an Intel Science Talent Search semifinalist and has presented his research to the American Junior Academy of Science division of the American Association for the Advancement of Science, the Human Factors and Ergonomics division of the Federal Aviation Administration, the Institute of Electrical and Electronics Engineers, and the Armed Forces Communications Electronics Association. Most recently, his research has been published in Imagine magazine.
In 2009, Steven and his teammates won $20,000 in the 2009 Moody's Mega Math Challenge, an applied mathematics competition sponsored by the Moody's Foundation and the Society for Industrial and Applied Mathematics. During the challenge, his team had 14 hours to analyze and submit a paper on the American Recovery and Reinvestment Act of 2009. The team was also featured on Bloomberg Radio's Taking Stock with Pimm Fox and Karen Moscow. His paper and presentation can be viewed at 2009 Winning Papers.
After graduating from High Tech, Steven plans to attend Columbia College of Columbia University to study neuroscience and physics.
Question: How did you determine the stimulus plan would be a success?
Steven Castellano: So at the Moody's Challenge basically you wake up you get your computer set up with a group of five kids and at 7 am you download a document and this is year was the stimulus package and how effective will it be. And I know the first hour I would say was the most difficult because I don't really think we've got a lot done. You're kind of just doing a lot of research and you're wondering how we're going to do this, how are you going to be able to analyze the stimulus when like economists are doing this 24/7 and they haven't reach upon conclusion and you know, you just kind of say what assumptions are we going to make and how we are going follow through with it and that first hour is probably the most nerve-wracking in that sense because you don't really know your direction and you start to plot a course that may not be successful.
So what we ultimately did was we look at how much money was being spent in each sector, if it's education, or an infrastructure and then we look at how many jobs are generally created per dollar in that sector by looking at like an average of few if you graph the total amount of revenue versus the total amount of jobs, you'll get kind of get an approximate for the rate of how money jobs per dollar you'll get and then in addition to that then we did like an infinite serious calculation in which you look at like the marginal propensity it consume and that's basically how much money a person will spend per dollar and you multiply that infinitely because as one person gets the money in the new job and they'll spend it and then I could promote more job for another sector.
So that's kind of the first analysis we did to see how many jobs will be created and we determine that there would be about 3.1 million jobs created using that analysis. We also found that in terms of like bank for your buck the most jobs per dollar it wasn't education sector because of our, as I said the total jobs for total revenue sort of analysis we did and taxes were actually, were actually the least like bank for your buck but because they are the largest part of the stimulus they did create the most jobs.
So you know, we weren't necessarily sure if we agree with the breakdown of the stimulus. We would say maybe less tax cuts and more spending on education but overall we found that it would probably create 3.1 million jobs in that sense and in addition to that, then we ask to analyze unemployment. So we look at previous trends in unemployment with the 1930s recession I think 60s recession and 1980s recession and we found that first statistically significant decreased unemployment occurred 3 years after the first statistically significant increase on federal spending and all of three of these instances. So we kind of made a linear regression because I have the least degrees of freedom for federal spending is the per cent of the GDP versus the unemployment rate. When we did this we noticed that it quickly became negative unemployment at the federal spending that Obama is proposing because it is unprecedently high.
So then we, what we did was we saw that there is Okun's law and it relates federal spending and unemployment it was like a natural algorithmic relationship, so we then apply the natural algorithmic regression toward data set and found that there was actually a stronger fit in with the linear regression and we are able to approximate that. Since it's a three year offset factor between the unemployment rate and federal spending percent of GDP is that, this federal spending in three years or reduce the unemployment rate to about 6.2 percent versus without the stimulus it would be more in the order of 9 percent so that was like our second major analysis. We also set conditions for if the 2nd stimulus will be needed. What benchmarks do we expect as far as the unemployment reaching 6 percent in three years and if we need a second stimulus, we mention the breakdown and we said that like food stamps and education spending would, would probably the most beneficial so that was our analysis and we have five of us working 14 hours straight in a crazy hectic environment but we definitely produce a pretty cool paper if you consider that a brief time spend and just like the passion that went into it and produce.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
The newly discovered galaxies are 62x bigger than the Milky Way.
- Two recently discovered radio galaxies are among the largest objects in the cosmos.
- The discovery implies that radio galaxies are more common than previously thought.
- The discovery was made while creating a radio map of the sky with a small part of a new radio array.
An extremely active galaxy<p> <br> </p><p>Radio galaxies are galaxies with extremely active central regions, known as nuclei, which shine incredibly brightly in some part of the electromagnetic spectrum. They are known for emitting large jets of ionized matter into intergalactic space at speeds approaching that of light. They are related to quasars and blazars. It is thought that supermassive black holes are the energy source that make these galaxies shine so brightly. </p><p>What makes these two galaxies (known as MGTC J095959.63+024608.6 and MGTC J100016.84+015133.0) so interesting is their size. Only 831 similar, "giant radio galaxies" are known to exist. As study co-author Dr. Matthew Prescott explains, these are particularly large even for <a href="https://www.forbes.com/sites/jamiecartereurope/2021/01/18/we-just-found-two-mysterious-galaxies-62-times-bigger-than-our-milky-way-say-scientists/?sh=76edf29c2892" target="_blank" rel="noopener noreferrer">giants</a>:</p><p>"These two galaxies are special because they are amongst the largest giants known, and in the top 10 percent of all giant radio galaxies. They are more than two mega-parsecs across, which is around 6.5 million light-years or about 62 times the size of the Milky Way. Yet they are fainter than others of the same size."</p><p>The smaller of the two is just over two megaparsecs across, roughly six and a half million light-years. The larger is almost another half megaparsec larger than <a href="http://www.sci-news.com/astronomy/giant-radio-galaxies-09266.html" target="_blank">that</a>. <br></p><p>Exactly how these things get to be so massive remains a mystery. Some have proposed that they are ejecting matter into unusually empty space, allowing for the jet to expand further, though some evidence contradicts this. The most commonly suggested idea is that they are simply much, much older than the previously observed radio galaxies, allowing more time for expansion to occur.</p>
How does this change our understanding of the universe?<p> While exciting and impressive on their own, the findings also suggest that there are very many more of these giant galaxies than previously supposed. If you were going off the previous estimates for how typical these galaxies are, then the odds of finding these two would be 1 in 2.7×10<sup>6. </sup>This suggests that there must be more, given that the alternative is that the scientists were impossibly lucky. </p><p> In the study, the researchers also apply this reasoning to smaller versions of these galaxies, saying:</p><p> "While our analysis has considered only enormous (>2 Mpc) objects, if radio galaxies must grow to reach this size, then we may expect to similarly uncover in our data previously undetected GRGs with smaller sizes."</p><p> Exactly how common radio galaxies and turn out to be remains to be seen. Still, it will undoubtedly be an exciting time for radio astronomy as new telescopes are turned skywards to search for them.</p>

Daydreaming can be a pleasant pastime, but people who suffer from maladaptive daydreamers are trapped by their fantasies.

One maladaptive dreamer spent hours a day dreaming he was a powerful man who could solve the world's problems.
(Photo: Pixabay)<p>Daydreaming is an indulgence of the mind and imagination, one provided courtesy of the <a href="https://www.sciencedirect.com/topics/neuroscience/default-mode-network#:~:text=The%20default%20mode%20network%20(DMN,and%20Exercise%20Psychology%20Research%2C%202016" target="_blank">default mode network</a>, a network of interacting brain regions that is active even when the conscious mind is not. But like so many of life's indulgences—wine, steak dinners, video games, and even <a href="https://www.healthline.com/health-news/why-too-much-exercise-can-be-bad-042514" target="_blank">exercise</a>—too much daydreaming can be harmful to our well-being. When daydreaming crosses that threshold, it can be considered maladaptive.</p><p>This disorder was first identified by <a href="https://haifa.academia.edu/EliSomer" target="_blank">Eli Somer</a>, a professor of clinical psychology at the University of Haifa, School of Social Work, in <a href="https://link.springer.com/article/10.1023/A:1020597026919" target="_blank" rel="noopener noreferrer">a 2002 paper</a>. That paper looked to six patients in a trauma center whose daydreaming habits replaced human interactions or interfered with their standard life functions, such as going to school or holding down a job. </p><p>Since then, other case studies have looked at <a href="https://www.healthline.com/health/mental-health/maladaptive-daydreaming#:~:text=Maladaptive%20daydreaming%20is%20a%20psychiatric,life%20events%20trigger%20day%20dreams." target="_blank" rel="noopener noreferrer">maladaptive daydreamers</a> and compiled a list of potential symptoms. These include vivid, richly-detailed daydreams; abnormally long daydreaming sessions; daydreams triggered by real-life events; daydreaming sessions that interrupt sleep; and repetitive motions or whisperings while daydreaming. On average, one study reported, maladaptive daydreamers spend <a href="https://bigthink.com/bps-research-digest/people-with-maladaptive-daydreaming-spend-an-average-of-four-hours-a-day-lost-in-their-imagination" target="_self">four hours a day</a> housed in their imaginations.</p><p>"This is not like rehearsing a conversation that you might have with a boss," <a href="https://www.cnn.com/2016/12/30/health/maladaptive-daydreaming-feature/index.html" target="_blank" rel="noopener noreferrer">Somer told CNN</a>. "This is fanciful, weaving of stories. It produces an intense sense of presence."</p><p>While such symptoms are common, though not comprehensive or guaranteed, how maladaptive daydreams manifest are naturally individual to the dreamers. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6426361/" target="_blank" rel="noopener noreferrer">In one case study</a>, researchers analyzed the diary of a man codenamed "Peter." Peter described investing as many as 14 hours a day online. The news and images he happened upon would trigger related fantasies. For example, he may envision himself as a multimillionaire genius who could prevent bad news from occurring or self-insert himself into the power fantasies of superhero movies or police procedurals for hours at a time.</p><p>"When I felt this pain as a child, I started imagining how things could be different. I created stories which never happened. To suppress that pain I would hug my pillow or quilt, thinking I was being comforted by someone else," Peter wrote.</p><p>In an interview with CNN, Cordellia Rose described her maladaptive daydreaming like a drug and noted that her daydreams developed into intricate storylines that could last for years. These stories proved so distracted that she was unable to complete everyday tasks such as driving lessons.</p><p>"You get hooked on it, because it can be like an action movie in your head that's so gripping that you cannot turn off," Rose told CNN. "This [condition] needs to be public, because these are people suffering, and badly."</p><p>To be clear, maladaptive dreaming is not a <a href="https://www.webmd.com/schizophrenia/guide/what-is-psychosis#1" target="_blank" rel="noopener noreferrer">psychotic disorder</a> like schizophrenia. Daydreamers such as Peter and Rose are aware that their fantasies are as unreal as they may be unrealistic. Because of this, many maladaptive dreamers understand the difficulties they face and the real-life losses they have endured for the sake of their fantasies. </p>
More research needed<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="6fdb8ca5dcc87c58b441d9c7cd766f35"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/vI7b4_-MA8g?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Researchers don't have a <a href="https://www.medicalnewstoday.com/articles/319400" target="_blank" rel="noopener noreferrer">standard diagnosis or treatment for maladaptive daydreaming</a> because they aren't yet sure it's a unique psychological condition. Maladaptive daydreaming has not been included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition—blessedly abbreviated as the DMS-5—the definitive book on mental disorders. To date, there isn't enough evidence to determine if maladaptive daydreaming is a separate condition or a manifestation of an already listed disorder.</p><p>Somer has developed a <a href="https://www.sciencedirect.com/science/article/abs/pii/S1053810015300611" target="_blank" rel="noopener noreferrer">14-point scale</a> to help people determine whether they are experiencing maladaptive-daydreaming symptoms, but the results only indicate whether an individual should seek help. They provide no formal diagnosis.</p><p>Also, maladaptive daydreaming is often expressed alongside other conditions, such as anxiety disorders, <a href="https://www.psychiatryadvisor.com/home/topics/anxiety/ptsd-trauma-and-stressor-related/high-prevalence-of-maladaptive-daydreaming-among-patients-with-dissociative-disorders/" target="_blank" rel="noopener noreferrer">dissociative disorders</a>, attention deficit disorders, and obsessive-compulsive disorders. And the researchers of Peter's case study noticed a striking similarity between his condition and those with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164585/" target="_blank" rel="noopener noreferrer">behavioral addition response</a>—including analogous responses with preoccupation, mood modification, tolerance, and withdrawal. It may be that maladaptive daydreaming is an expression of these, or other, disorders.</p><p>It's worth noting that similar empirical hurdles exist for other well-known, though not formalized, disorders. Orthorexia, sex addiction, misophonia, internet addiction, and parental alienation syndrome are all <a href="https://www.verywellmind.com/whats-missing-from-the-dsm-4145344#:~:text=This%20diagnosis%20covered%20patients%20who,%22%20or%20%22unspecified%20disorder.%22" target="_blank" rel="noopener noreferrer">likewise absent from the DSM-5</a>. For maladaptive daydreaming and these other conditions, it's simply a case of more evidence and research needed before a determination can be made.</p>
A growing understanding of maladaptive daydreaming<p>The question of labeling is a tricky one—not only from a medical point-of-view but also a prosocial one. Some people find having a recognized condition validating; they feel it promotes social acceptance and makes seeking treatment easier. Others find such labels stigmatizing and restricting.</p><p>But the question of how to label something is an academic one. It isn't to say that the experience doesn't exist. It does, and whether maladaptive daydreaming ultimately enters the DSM-5 or not, awareness is growing. <a href="https://daydreamresearch.wixsite.com/md-research/links" target="_blank">Online communities</a> now exist to give support and spread awareness. And regardless of a condition's presence in the medical literature, if symptoms disrupt work, school, or social lives, help should be sought.</p><p>Thanks to the efforts of psychologists and the community, maladaptive daydreaming, unlike Thurber's literary creation, is no longer "inscrutable to the last." And those who suffer it are no longer relegated to a firing-squad of their own mind but can find they help the need.</p>

Psychologists point to specific reasons that make it hard for us to admit our wrongdoing.
- Admitting mistakes can be very difficult for our ego and self-image, say psychologists.
- Refusing to own up to guilt boosts the ego and can feel more satisfying.
- Not acknowledging you are wrong can lead to psychological issues and ruined relationships.
