Some call Mary Shelley’s famous novel Frankenstein the first science fiction novel. Her theme is repeated in many later stories. Someone creates a powerful being or force only to see the creation become a weapon of destruction.

The printing press, popularized by Johannes Gutenberg in the 15th century, was an amazing technological advance. It made possible the creation of reading material cheap enough for ordinary people to buy. All sorts of information became available. Everything from the Bible to new scientific theories to incendiary tracts was produced and consumed.

From that time, ordinary people had access to ideas and to the pleasures of reading. Countless lives have been saved through accessible knowledge.

However, cheap printing also made possible the spread of false information like the infamous Protocols of the Elders of Zion, a hoax purporting to prove a Jewish plot to dominate the world. This type of easily accessible lying contributed to the murder of millions in World War II.

The digital age has multiplied the Gutenberg effect many times over. Warnings of hurricanes and other disasters wake us from sleep, pinged from our mobiles. Supreme Court decisions and election results are known instantly.

But anyone with an email account or a twitter handle can spread stories, verified or not, sending them off like so much tree pollen in a spring wind.

Efforts at some kind of control over hate material and outright lying are necessary but have limited success.

In truth, the only controls over this digital flood are we the consumers. We can be tempted by Frankenstein rumors or we can choose trusted sources for our information.
