Have you ever noticed that when something important is missing in your life, your brain can only seem to focus on that missing thing? On this week's Radio Replay, we bring you a March 2017 story about the phenomenon of scarcity, and how it can blind us to the big picture. Then, we go to the opposite end of the spectrum to look at the perils of excess. We'll bring you an October 2016 conversation with Brooke Harrington, a sociologist who wanted to know what it's like to be one of the richest people on the planet.

"Be the change you wish to see in the world." It's a popular quote that's made its way onto coffee mugs and bumper stickers — but it's not the easiest principle to live. On this week's Hidden Brain, we meet Royce and Jessica James, a couple who decided to raise their daughter in a gender-neutral way. It was far harder than they ever could have imagined.

There is one truth that has endured through the first two years of Donald Trump's presidency: he has kept the support of the core voters who propelled him to the White House. This week on Hidden Brain, we explore two competing perspectives on the motivations of Trump supporters, and what they can tell us about the state of our union.

We often assume our life experiences are the root of our political ideologies. But what if there is something deeper at play?

You've certainly heard some variation of the phrase "be a man." But what does that even mean? On this episode of Hidden Brain, we discuss masculinity.

Nearly a quarter century ago, a group of women accused a prominent playwright of sexual misconduct. For the most part, the allegations went nowhere. In 2017, in the midst of the #MeToo movement, more women came forward to accuse the same playwright of misconduct. This time, everyone listened. On this episode — originally broadcast in February 2018 — we explore the story through the lens of social science research and ask, "Why Now?" What has changed in our minds and in our culture so that allegations of sexual harassment and assault are being taken more seriously than they were in the past? A note: This story includes descriptions of sexual harassment and assault. It may not be suitable for all listeners.

When Randy Gardner was 17, he won a world record for going eleven days without sleeping. On this Radio Replay, Randy shares insights from that experience and warns others against copying his stunt. Later in the program, we speak with neuroscientist Matthew Walker about the mind and body benefits of eight full hours of sleep.

After a disaster happens, we want to know whether something could have been done to avoid it. Did anyone see this coming? Many times, the answer is yes. So why didn't the warnings lead to action? This week, we explore the psychology of warnings with a visit to a smelly Alaskan tunnel, a gory (and fictional) murder plot, and even some ABBA.

If you live in a big city, you may have noticed new buildings popping up — a high-rise here, a skyscraper there. The concrete jungles that we've built over the past century have allowed millions of us to live in close proximity, and modern economies to flourish. But what have we given up by moving away from the forest environments in which humans first evolved? This week, we discuss this topic with psychologist Ming Kuo, who has studied the effects of nature for more than 30 years.

Have you ever had a job where you had to stop and ask yourself: what am I doing here? If I quit tomorrow, would anyone even notice? This week on Hidden Brain, we talk with anthropologist David Graeber about the rise of what he calls "bullshit jobs," and how these positions affect the people who hold them.
