Have you ever taken an IQ test? Think about the results. Did you do well? You might have gotten a high score, but, often, intelligence doesn’t have anything to do with rationality. There is a marked difference between the two, although we often conflate them. We talk with York University associate professor Maggie Toplak and Boston University professor Carey Morewedge about why even smart people do irrational things.

Obsessed with work, insensitive, socially detached, and neglectful of family and friends. Those may not be the most endearing qualities, but they are just a few of the common characteristics that longtime innovation researcher, Melissa Schilling found when studying some of the world’s most famous and prolific inventors in the fields of science and technology.

Schilling, a professor of management and organizations at New York University’s Stern School of Business, explores the ingenuity of eight outstanding innovators, including Albert Einstein, Marie Curie, Steve Jobs, Elon Musk and more. She’s the author of, “Quirky: The Remarkable Story of the Traits, Foibles, and Genius of Breakthrough Innovators Who Changed the World.”

We all know the legacy that Sputnik had on U.S. science education. Washington poured more than a billion dollars into overhauling the U.S. science curriculum. But television was transformed too. According to Ingrid Ockert, a Haas Fellow at the Science History Institute and a NASA History Fellow, the television show “Continental Classroom” was launched as a direct response to the Sputnik challenge. Five days a week, “Continental Classroom” was broadcast into American homes to encourage and inspire budding scientific minds.

From “Watch Mr. Wizard” to “Mythbusters,” lots of Americans have grown up watching various science television programs. Ockert walks us through how science has changed television, and how television has influenced science.

Are you a self-proclaimed germaphobe like President Trump? Well, if you think your home is sparkling clean, try walking around with a microscope. According to Rob Dunn, a professor of Applied Ecology at both North Carolina State University and the Natural History Museum of Denmark, we are surrounded by thousands of tiny species, living on every imaginable surface. And while some bacteria can be harmful, most just humbly co-exist with us... and some are more helpful than we know.

In his book, “Never Home Alone: From Microbes to Milipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live,” Dunn takes a safari through our homes, introducing us to these invisible creatures and explaining how, despite our fervent efforts to sanitize the world, we may be negatively affecting our own health.

In 21st century America, citizens assert their individual rights loud and clear. Media coverage shows that Americans defend, debate, and demand individual liberties, including freedom of speech and the right to bear arms. Yet just over 100 years ago, Americans valued the greater good of the country more than their personal freedoms, according to Christopher Capozzola, the author of “Uncle Sam Wants You: World War I and the Making of the Modern American Citizen.” Capozzola explains that the change from prioritizing one’s country to one’s self occurred during World War I. As the federal government gained more power during the First World War, its growing control was countered by a demand to protect individual rights, Capozzola says. The changing relationship between citizen and country would powerfully shape the society we now live in.

In a modern-day Mexican standoff, the U.S. and China are confronting each other over trade practices. The United States believes China has been luring away jobs and stealing American technology. But what if the issue isn’t that China is stealing innovations, but that it is out-innovating us? George Yip, a professor of marketing and strategy at Imperial College Business School in London thinks that the Chinese are no longer mere imitators but have become serious innovators in their own right.

Ian Bremmer, president of Eurasia Group and GZERO Media, believes that the U.S. government has some valid complaints, but that China is nonetheless becoming increasingly competitive in the innovation game.

Yip and Bremmer discuss China’s increasing dominance on the global stage, and consider what’s at stake for the U.S.

Spiders and grizzlies and snakes, oh my! Ask someone what they are afraid of, and the answer is likely to be something like a plane crash or shark attack. But the authors of the book “Worried?: Science Investigates Some of Life’s Common Concerns,” Eric Chudler and Lise Johnson explain why they believe we often waste our energy worrying about the wrong things. Chudler, a neuroscientist at the University of Washington and Johnson, an assistant professor of physician assistant studies at Rocky Vista University, say that we feel stressed out about things that are highly unlikely to happen. Instead, we should be more focused on seemingly mundane threats, they explain. Chudler and Johnson talk to us about the risk behind everything from aluminum to red wine, and share ways to take control of the things we fear.

If you’re reading this on your smartphone, it might be time to reevaluate how much time you spend in front of a screen. Author Cal Newport offers a road map toward digital minimalism.

Then, how did American capitalism become so unequal? And where is it headed? Washington Post columnist Steven Pearlstein thinks it’s time for a change.

Think you might need a digital detox? You’re not alone. It’s becoming more and more of a trend to take time away from our online lives. Cal Newport author of “Digital Minimalism: Choosing a Focused life in a Noisy World” shares his approach to avoiding digital distraction and reclaiming time. He discusses how to be more intentional about how you use technology, and more aware about how technology uses you. We’ll discuss everything from the neuroscience of the human brain to how to do your own 30-day digital detox.

Capitalism is a recurring theme among the ever-growing list of Democratic presidential candidates. But many Americans of all political stripes have concerns about our free market economy and whether it is working for them, according to Steven Pearlstein, a Pulitzer-Prize winning columnist for The Washington Post and author of "Can American Capitalism Survive: Why Greed Is Not Good, Opportunity Is Not Equal, and Fairness Won't Make Us Poor."

We talk with Pearlstein about the importance of fairness in economic growth, and consider some ways to reinvent capitalism.
