The Great Science Communicator

"Astronomer Carl Sagan had a 'consumer tested' method for busting pseudoscience. Here’s how it worked.

"In chapter 12 (The Fine Art of Baloney Detection) of Sagan’s ‘The Demon Haunted World,'' he lays out a method for detecting and debunking pseudoscience. Whether tackling astrology, channeling, creationism, homeopathy, or alien abductions, Sagan’s ‘Baloney Detection Kit’ can handle the challenge. Scientists utilize the tools in this kit as a regular part of their work, and I think it’s time we learn how to use them in our day-to-day lives."

Carl Sagan: Prophet Of Doom Or Hope

"Did Carl Sagan see 2020 coming 25 years ago? Here's why some people think he did.

"A certain excerpt from The Demon Haunted World has gone viral countless times in the last few years, often being called prophetic and frightening. What does it really mean, though? Did Carl Sagan predict the future? Science denial, conspiracy theories, power disparities, media influence, and authoritarianism were all things he showed great concern over, but did he have sufficient reason for concern in his own time? "This Demon Haunted World review and discussion is my way of continuing the mission of Carl Sagan, Ann Druyan, and their peers. As Sagan wrote just before his internet-famous words in DHW, 'Not explaining science seems to me perverse. When you're in love, you want to tell the world.'"

The Wisdom Of Carl Sagan

“Science is a way to call the bluff of those who only pretend to knowledge… It can tell us when we’re being lied to. It provides a mid-course correction to our mistakes.”
