Big Think, the YouTube for intellectuals, is devoting the next 30 days to highlighting the most dangerous among ideas. Here's how the editors describe the theme:

Throughout the month of August, Big Think will introduce a different "dangerous idea" each day. Brace yourself: these ideas may at first seem shocking or counter-intuitive--but they are worth our attention, even if we end up rejecting them. Every idea in the series will be supported by contributions from leading experts, from the world's top theoretical physicist Stephen Hawking, to prolific legal scholar Judge Richard Posner, to Nobel Prize-winning economist Gary Becker, to linguist and philosopher Noam Chomsky.


Today's dangerous idea is posed by bioethicist Jacob Appel who suggests that the government should supplement our drinking water with lithium, which some studies suggest might lower suicide rates. You can watch Appel pitch his dangerous idea below and read more about his proposal--along with the arguments against-- at Big Think's Dangerous Ideas blog.

What do readers think? My own feeling is that in a world of Glenn Beck conspiracy theories and widespread government distrust, that at least in the short term, the political dangers of the idea outweigh the possible public health benefits.




UPDATE: Big Think sent along this news release detailing upcoming Dangerous Ideas.


BigThink.com Declares August "The Month of Thinking Dangerously"

New York, NY, August 2, 2010 - Had Copernicus been too terrified to
publish his theory of heliocentrism, how long would it have taken
people to realize that Earth, in fact, revolves around the Sun? Had
U.S. Secretary of State William Seward folded to public scrutiny and
not purchased Alaska from Russia in 1867 for two cents an acre,
America would face a worse oil crisis today -- and may have faced a
nuclear threat on North American soil during the Cold War. In the
spirit of those who are brave enough to advance seemingly radical
ideas, Big Think presents "The Month of Thinking Dangerously."

Throughout the month of August, Big Think will introduce a different
"dangerous idea" each day. Brace yourself: these ideas may at first
seem shocking or counter-intuitive -- but they are worth our
attention, even if we end up rejecting them. Every idea in the series
will be supported by contributions from leading experts, from the
world's top theoretical physicist Stephen Hawking, to prolific legal
scholar Judge Richard Posner, to Nobel Prize-winning economist Gary
Becker, to linguist and philosopher Noam Chomsky. Kicking off the
first week of the series, Big Think announces its first five dangerous
ideas:

1. Drug Our Drinking Water (August 2)

When the government added fluoride to our drinking water in the 1940s,
it was hailed as a great public health success. Why shouldn't the
government add a trace amount of lithium--which has been shown to
limit suicide -- to our water as well? It may save 12,000 lives a
year.

2. Sell Your Kidneys (August 3)

As an adult you're capable of making your own economic decisions about
your livelihood -- why shouldn't you have the right to sell one of you
kidneys?

3. Erase Traumatic Memories and Achieve Your Own "Eternal Sunshine" (August 4)

Scientists have already been able to eliminate certain memories in
mice and are expected to be able to the same in humans. Shouldn't each
of us have the right to wipe traumatic events from our mind to ensure
a happier life?

4. Blot Out the Sun -- Or Face Extinction (August 5)

Nobel Prize-winning chemist Paul Crutzen argues that adding "about 3
million tons per year of sulfur" to the atmosphere would lower average
temperature at the Earth's surface by about 4 degrees Fahrenheit.

5. Abandon Earth -- Or Face Extinction (August 6)

"It will be difficult enough to avoid disaster on planet Earth in the
next hundred years, let alone the next thousand, or million. The human
race shouldn't have all its eggs in one basket, or on one planet,"
says Stephen Hawking. It's time to abandon Earth.

These are just five of the 30 dangerous ideas in Big Think's latest series.
