Why Traffic Lights Signal Democracy

Question: What’s the most unexpected insight to emerge from your current work?


Rachel Maines: Well, actually I'm working on a book about building codes, which sounds deadly dull compared to the other things that I've done, but what I'm interested in is injury epidemiology, which my second book's about, “Asbestos and Fire,” and I'm interested in how all the rules that go with our built environment, building codes, if you go out, if you go out and walk around in New York City or anywhere, just sometime when you're not thinking about anything else, take note of how much of the built environment has to do with protecting ourselves against danger. The curbs on the street, the lines that are painted on the street, the traffic signals, the signs. These are all aspects of the built environment that help keep our death rate down. And parts of the world where they don't do that kind of thing or where they don't read the signs or pay attention to them and they're, unfortunately, a lot of places like that. They have the signs and they don't read them or pay attention, they have a much higher death rate. And it's a much more serious and somber subject than these other three. I sort of go back and forth between death and destruction and fun and games and, you know, it kind of keeps life interesting. I think that the most fascinating thing about the work that I'm doing now, that strikes me, I think the most interesting insight, is that it's not so much having a democracy that makes those codes, those building codes and safety codes work, it's the habit of democracy. That it just, you know, making your country a democracy, you know, doesn't inculcate that habit, but we're accustomed to, like, you know, in elementary school when we learn Robert’s Rules Of Order, right? And so we're accustomed to the parliamentary procedure, and kids in Britain, same thing, you know, they know all about that.


And by the time, you know, a few generations have gone by, you're used to the idea that you don't run red lights. You don't, you know, ignore signs that say wrong way. You know, you don't cross the yellow lines if you want to stay alive. And that somehow is a part, although it's an ordering and some people would say a kind of hegemony over people's lives, it really does seem to be a tool of keeping people alive in democracy. It's an elaborate way of putting it, but I'm sure you see what I mean, that it's a lifesaver. And keeping people alive is one of the functions of democracies.

Childhood sleeping problems may signal mental disorders later in life

Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.

Personal Growth
  • We spend 40 percent of our childhoods asleep, a time for cognitive growth and development.
  • A recent study found an association between irregular sleep patterns in childhood and either psychotic experiences or borderline personality disorder during teenage years.
  • The researchers hope their findings can help identify at-risk youth to improve early intervention.

    Why do people believe in conspiracy theories?

    Are we genetically inclined for superstition or just fearful of the truth?

    • From secret societies to faked moon landings, one thing that humanity seems to have an endless supply of is conspiracy theories. In this compilation, physicist Michio Kaku, science communicator Bill Nye, psychologist Sarah Rose Cavanagh, skeptic Michael Shermer, and actor and playwright John Cameron Mitchell consider the nature of truth and why some groups believe the things they do.
    • "I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking," argues Kaku. The theoretical physicist says that science goes against "natural thinking," and that the superstition gene persists because, one out of ten times, it actually worked and saved us.
    • Other theories shared include the idea of cognitive dissonance, the dangerous power of fear to inhibit critical thinking, and Hollywood's romanticization of conspiracies. Because conspiracy theories are so diverse and multifaceted, combating them has not been an easy task for science.

    COVID-19 brain study to explore long-term effects of the virus

    A growing body of research suggests COVID-19 can cause serious neurological problems.

    • The new study seeks to track the health of 50,000 people who have tested positive for COVID-19.
    • The study aims to explore whether the disease causes cognitive impairment and other conditions.
    • Recent research suggests that COVID-19 can, directly or indirectly, cause brain dysfunction, strokes, nerve damage and other neurological problems.
