Please submit only once. RECENTLY, AT THE LONDON 2012 OLYMPIC Games, a famous Austrian swimmer found a creative explanation for his moderate success: He argued that intelligent athletes have a disadvantage in competitions because they tend to think too much. In an attempt to prove his claim, he pointed to an intelligent alpine skier who only won four World Cup races and an—in his opinion— rather unintelligent one who won more than 50. This might be an extreme example, but we encounter causal oversimplification and faulty generalizations so often in our daily lives that we barely notice them anymore. What makes matters worse is that politicians throughout the world—be it intentional or not—use logical fallacies as tools to justify unmoral actions and gain votes, inciting rac- 40 ism, sexism, and fear as collateral damage along the way. Their success is based on the lack of a basic understanding of logical fallacies and critical thinking. Much more than from a specific scientific concept, our society would benefit from knowledge of (and training in) scientific reasoning. The Austrian swimmer—although apparently hindered by his intelligence— managed to win 34 medals at major events throughout his very successful career.

E-mail: [email protected] I AM AN ENVIRONMENTAL TOXICOLOGIST, and I wish that people understood the concepts of hazard and risk and the differences between the two. Chemicals are hazardous—even things we might think of as benign or “natural”—but they only cause a problem when they reach a concentration that is associated with a hazard. Risk [is a measure of both] hazard and exposure. I am frustrated by news and social media outlets that incite fear of “hazardous chemicals” in the general public without ever considering the level to which exposure is occurring.

In your inaugural address, announce the biggest challenge facing your country today and how you will use science to address it. NextGen Speaks logical debate about development justice, achieving emissions reductions in established industries, and the blind pursuit of governance rigor…. Scientific perspectives have been largely overlooked. We need offsets that contribute to genuine sustainable outcomes, but we also need to make progress on climate change mitigation, and offsets enable a more economically palatable transition.

This mindset allows many to safely ignore evolution, or, worse, reject it entirely.... [T]he misunderstanding that evolution occurs primarily on a geologic time scale has impeded societal endeavors such as human medicine, harvest of natural resources, and conservation efforts. But times are changing. Physicians are updating antibiotic dosage suggestions to curb the evolution of drug-resistant pathogens. Fisheries management agencies are applying life history theory to effectively manage wild stock. Conservation groups are realizing the importance of conserving genetic variation in threatened species…. A public grasp of one of the biggest ideas in contemporary evolutionary biology is within reach. CREDITS: (ILLUSTRATION) JOE SUTLIFF/JOESUTLIFF.COM; PHOTOS COURTESY OF THE AUTHORS STEPHEN P.

It frustrates me to no end that available, effective inventions to combat disease aren’t always used due to media reporting and mass hysteria.

E-mail: [email protected] MÁTÉ VARGA what exists in our nuclear DNA, one has to grapple with a startling idea: Life as we know it would not exist without these small organelles, once mere foreign bodies inside our single-celled ancestors. For all our arrogance, humans are not independent from other life on this planet; the story of the natural world is not only about the struggle of individual species but about the relationships between them. Understanding our interconnectedness provides plenty of food for thought—and thoughtful citizens make thoughtful stewards. Department of Genetics, Eötvös Loránd University, Budapest, H-1117, Hungary. E-mail: [email protected] [I WISH NON-SCIENTISTS understood] the idea that one of the biggest threats to public health is the rise in the drug-resistant pathogens. Due to increased global trade and travels, these pathogens can spread easily. Our global research system is necessary and timely. We never know when local problems and solutions may become global, and every part of the world has a contribution to make.

E-mail: [email protected] I WORK IN THE FIELD of medical genetics and genetic counseling, an area where the contact with the nonscientific public is very intense. It would be great if we could better explain concepts related to risk of recurrence, recessive inheritance, and de novo mutations…. Sometimes it is very difficult to alleviate the sense of guilt that parents of malformed children experience…. …I WORK WITH DIFFERENT SPECIES OF fungi, many of which are pathogens.…I wish more people, non-scientists as well as some prominent scientists, understood that organisms that cause disease are defined as pathogens only in relation to the organisms they affect.…Pests causing infestations and epidemics are usually an integral part of the ecosystem. Often, we overlook the fact that diseases occurring at a larger scale are caused by an ecosystem imbalance.… [M]any times, imbalances are caused by anthropogenic factors and are indicators of our own shortsighted harmful activities that lead to medical and EDUARDO PREUSSER DE MATTOS I WISH THE PUBLIC UNDERSTOOD THE ENDOsymbiotic theory. In realizing that mitochondria have a radically different genome than …THE IDEA OF EVERincreasing complexity is rooted in a strong adherence to the old Aristotelean world view of hierarchical classification of living things, which still permeates our everyday thinking. But in this case, it is time to let it go. The past two decades provided plenty of evidence that the endless variety of forms surrounding us is the product of just a handful of signaling pathways and gene regulatory modules, which are used iteratively over and over during development. Just as the imaginative combination of a limited number of Lego bricks can create a dazzling array of forms, so can changes in the regulation of key genes create new pigmentation patterns, new appendages or new behaviors. If people came to terms with this concept, most likely they would accept more readily our place in nature as just one branch on the Tree of Life….

E-mail: [email protected] I AM IN SCIENCE POLICY AND I WISH EVERYone had a better understanding that science itself is not politicized or inherently supportive of one party or another. Too many people, I think, believe that science serves only a particular viewpoint or political argument. In reality, science is the underlying foundation on which to make policy decisions that may or may not hinge on the science itself. With a better understanding of that, I hope people would not be as quick to criticize scientific reports and the scientists who produce them based solely on the conclusions.

E-mail: anish.goel@ boeing.com …A CLEAR UNDERSTANDING OF PHARMAcogenomics would lead to safer prescriptions, reduced risk of adverse side effects, minimized healthcare cost, and improved clinical outcomes. In addition, a better understanding of this concept will encourage the public to participate in clinical trials in order to bridge the knowledge gap among clinicians, scientists, and the non-medical community. This will pave the way for the advancement of medicine and improvement of standard practice. MICHAEL O. BACLIG Research and Biotechnology Division, St. Luke’s Medical Center, Quezon City, 1102, Philippines. E-mail: mobaclig@ stluke.com.ph [I WISH NON-SCIENTISTS UNDERSTOOD] THE concept of gene-environment interaction that could predispose us to the progression of certain diseases. Diseases are often multifaceted in nature, and studying merely genetics or simple in vitro models is not sufficient in recapitulating the environmental factors that we are exposed to across the years…. If everyone can take a small step to mitigate possible deleterious geneenvironment interactions by altering their lifestyles, we can potentially reduce our healthcare costs even without discovering novel treatments to delay or reverse the progression of the diseases plaguing the developed world.

STUDENT, ONE OF THE MOST challenging—and sometimes discouraging—things for me to explain to a non- scientist is why I chose to be a scientist, and why my research matters. The satisfaction and joy I have when accomplishing a hardearned research project, adding valuable data to a longterm study, or discovering a new question to explore can be intangible to a non-scientist. I don’t expect non-scientists to fully understand why I chose my career path, but the notion that science is a critical component to understanding our world, now more than ever, seems lost on many….

But, using scientific observations combined with sophisticated models, we can determine a range of what could happen and what most likely will happen….
