The biggest difference between good science and religion

| February 10, 2015 | 1 Reply

The difference between good science and any religion. Good science is proudly self-critical. The Edge 2014 annual question, answered by almost 200 writers, is this: “Ideas change, and the times we live in change. Perhaps the biggest change today is the rate of change. What established scientific idea is ready to be moved aside so that science can advance?”

Nation of skimmers rather than readers

| February 5, 2015 | 1 Reply

From the Washington Post, we learn that we are re-shaping our brains to accommodate the Internet.

Humans, they warn, seem to be developing digital brains with new circuits for skimming through the torrent of information online. This alternative way of reading is competing with traditional deep reading circuitry developed over several millennia.

About blacks, whites and the other so-called races

| December 27, 2014 | Reply

In the NYT, Carl Zimmer writes about the so-called races, based on real evidence:

In 1924, the State of Virginia attempted to define what it means to be white.

The state’s Racial Integrity Act, which barred marriages between whites and people of other races, defined whites as people “whose blood is entirely white, having no known, demonstrable or ascertainable admixture of the blood of another race.”

There was just one problem. As originally written, the law would have classified many of Virginia’s most prominent families as not white, because they claimed to be descended from Pocahontas.

So the Virginia legislature revised the act, establishing what came to be known as the “Pocahontas exception.” Virginians could be up to one-sixteenth Native American and still be white in the eyes of the law.

People who were one-sixteenth black, on the other hand, were still black.’

On average, the scientists found, people who identified as African-American had genes that were only 73.2 percent African. European genes accounted for 24 percent of their DNA, while .8 percent came from Native Americans.

Latinos, on the other hand, had genes that were on average 65.1 percent European, 18 percent Native American, and 6.2 percent African. The researchers found that European-Americans had genomes that were on average 98.6 percent European, .19 percent African, and .18 Native American.

Time to end the “war on drugs”

| November 12, 2014 | 1 Reply

What’s the drug war about? American psychosis, born of racism, but now one humongous wholly misguided attempt to put children into a protective bubble. But now there is some hope for change in the right direction, according to Ethan Nadelmann’s TED talk. He is Director of Drug Policy Alliance. Brilliant talk, concluding with a call to end the drug war.

Why there are not any civilizations without temples – Video featuring Jonathan Haidt

| October 31, 2014 | 1 Reply

Jonathan Haidt explains why there are not any civilizations without temples, starting at minute 14 of this video. This is the 2013 Boyarsky Lecture at Duke University. About 10,000 years we went from an almost instantaneous transition from hunter-gathers to Babylon. A huge part of our evolutionary development is this newly learned ability of humans to circling around sacred objects (religious and political objects are two dominant examples) in order to form teams. As we circle around, we generate a social energy that knits the social fabric, but also encourages Manichean thinking–us versus them, blinding us to our own faults and faulty thinking. No shades of gray are allowed when we are intensely groupish. This kind of groupish thinking is radically incompatible with scientific thinking. Science is squeezed out, replaced by sacred objects, groupishness and authoritarian obeisance.

At min 24, Haidt gets to the crux of his talk. Those of us who focus on the “care” (empathy) foundation of morality, often circle about it bonding with others like us, rejecting and denigrating the impulses and ideas that tend to drive those who are politically conservative.

I love this story about Indonesian macaques who borrowed a camera and took their own photos. It brings together intellectual property law and animal rights into one conversation.

Progress on the origin of life?

| October 13, 2014 | 1 Reply

From News.Mic:

One of the most challenging questions in basic biology and the history of evolution and life stems from the unknown origin of the first cells billions of years ago. Though many pieces of the puzzle have been put together, this origin story remains somewhat murky. But a team of researchers from the University of Cambridge believe they’ve accidentally stumbled on an answer, and a very compelling one at that.
