Fact-resistant humans are threatening the ability of Earth to sustain life

Andy Borowitz reports that "Scientists have discovered a powerful new strain of fact-resistant humans who are threatening the ability of Earth to sustain life."


Actually, we DO understand the psychology of this phenomenon.  We know that human cognition which includes storytelling and logical thinking did not evolve to discern TRUTH but simply to enhance the probability of survival and reproductive success.  Right?  We are exquisitely tuned to detect inauthentic or flawed STORIES, not whether or not the stories are based on or contradict hard evidence.  On the contrary, to conserve energy under severe cognitive load, we basically delegate reasoning from evidence and first principles — which is HARD — to much more subconscious heuristics that are predisposed to select those stories framed to confirm existing beliefs and to filter out those stories which contradict them.  It’s called ‘confirmation bias.'

Borowitz is right:  shocks required to break through confirmation bias could include hunger, thirst or even respiration.

Remembering Carl Sagan and his Legacy of Critical Thinking

It's hard to believe that Carl Sagan died 20 years ago.  But it's worth remembering his death because it's worth remembering his life, his belief in and dedication to public engagement with science.  In this last interview with Charlie Rose he articulates the two arguments that motivated him throughout his life to continuously seek new ways to communicate science to everyone.  First, he reminded us that science is power, surely the defining power of our time.
We live in an age based on science and technology with formidable scientific powers.... If we don't understand it ... then who is making all the decisions ... that are going to determine the world our children are going to live in?

Reason, Truth, Lies, Empiricism and Belief in the Age of the Internet

In the March issue of The New Yorker Jill Lepore posted an amusing rant on reason, truth, lies, empiricism and belief in the "Age of the Internet."

She asks a good question:  How do we know?  And what is the role of evidence?  Reason?

Lepore observes in this season dominated by the Republican debates and largely negative advertising based almost exclusively on unsubstantiated opinion and belief:
  1. "Tump doesn’t reason... He wants combat." 
  2. "Cruz’s appeal is to the judgment of God. 'Father God, please . . . awaken the body of Christ, that we might pull back from the abyss,' he preached on the campaign trail."
  3. "Rubio’s appeal is to Google."

Is it Christmas Everywhere in the Universe?

Is it Christmas everywhere in the Universe?  

Dennis Overbye, one of my favorite science journalists, has taken a stab at this question in a light-hearted and fun way in this article in the Times, asking himself, "would an alien know it is Christmas?"  I love how he manages to stimulate our thinking by posing some interesting questions with a few answers but without writing a treatise on the philosophy of science and religion.  How exactly does he do it?

A Journalist Asks "How Do We Know"

Dean Miller, the Director of the Center for News Literacy at Stony Brook University posted this warning on his New York Time blog.  News literacy, whether you are a producer or consumer of news, is based on skepticism and, perhaps more than anything else, a healthy awareness of your own bias.

But it seemed odd to me that he could ask the question "how do we know" and feel obligated to restrict his assessment of veracity to the text itself and not even mention objective sources or empirical evidence outside of the story.  Is that the best we can do?

Robotics Scientists Meet to Discuss Ethics

In October a group of leading robotics scientists and engineers met to discuss the ethical implications of their work.  Until recently a vast majority of industrial robots have been confined to cages where they work and humans are unwelcome.  Increasingly, however, we find robotic applications in our human world.  They are "aware" of us, sensing our presence, our identities, our activity and inferring from those data our intentions and goals.  And these robots act in our world too, based on their own objectives and what they can sense from their surroundings, including present human beings.
