This Month in the Archives

 

Dear Reader,

In celebration of Women’s History Month, explore the contributions women made by entering the labor force during the Industrial Revolution. Not only did their employment take them out of the household, their traditional sphere, it fundamentally altered their position in society. Also, our March 2019 issue includes a fascinating and relevant article on current research in conspiracy theories, making it a good opportunity to peruse the archives of human fear. Lastly, we paid tribute to our canine companions in February so this month we will feature our feline friends.

Enjoy the journey!

Women and Wages
TelephonesBeginning in the 1880s new telephone exchanges provided an excellent job opportunity for the growing number of women working outside the home.

The ways in which women are capable of earning money has historically played a major role in confronting gender inequality.

  • May 1901: A look at women inventors approving notes patents “yielding unusually large returns.”
  • September 1974: “The Changing Status of Women in Developed Countries” examines the demographics of women trying to balance home life and work life.
  • September 1982: Industrialization has had a profound effect over the centuries on how women earn wages.
  • September 2017: It turns out that if the gap between “women’s work” and “men’s work” is closed, the whole economy benefits. Here’s how to close the gap.

 

Conspiracy Theories
ConspiraciesWhy do some people believe in “highly improbable conspiracies”? There are some specific human traits that lend a hand.

What we think we know about the world often differs from reality. The Internet is underscoring the fact that there is a greater difference for some than for others, but the problem isn’t new. Who are the people drawn to conspiracy theories?

  • February 1938: “The Paranoid Personality” notes, almost apologetically, that such people are like everyone else, only to an “inconvenient or dangerous degree.”
  • February 2003: NASA sent astronauts to the moon several times. Except a few folks truly don’t believe it.
  • September 2009: A skeptic draws a straight line between paranoia and belief.
  • April 2017: Social scientists show that “users happily embrace false information as long as it reinforces their preexisting beliefs.”

 

Deciphering the Cat
Toilet water
CatBeautiful friend—with the heart of a killer: the “blotched tabby” allele is most common in Britain and countries colonized by people from there.

Cats and humans have been allies, housemates and (occasionally) friends and roommates probably ever since agriculture brought grain and mice within our homes.

  • June 1900: Mummified cats from Egypt were assumed to be “friends to the little children.”
  • November 1977: Subtle differences in the genome of cats bear traces of human migration, commerce and preferences over the past 10,000 years.
  • March 1984: The tale of the cat winds around the story of agriculture, grain and the highly adaptable (and hungry) house mouse.
  • June 2009: The melding of genetic and archaeological data point to where and when the wild cat turned into the domestic cat.
