Running in your sleep

Did you ever wake up suddenly because while you were having a dream because your body actually moved a bit? This poor dog was apparently having a running dream when his body kicked in . . . such a rude awakening! What protects us from physically acting out our dreams and hurting ourselves? The body functions to paralyze itself during REM sleep to protect us from self-damage that would occur if we acted out scenes from our dreams. [Via hahahaimontheinternet]

Color-coded history

Consider this description of a significant and tragic event in American history:

[Occurring in May and July 1917, this event] was an outbreak of labor and racially motivated violence against blacks that caused an estimated 100 deaths and extensive property damage in [an American industrial city]. It was the worst incident of labor-related violence in 20th century American history, and one of the worst race riots in U.S. history. It gained national attention. The local Chamber of Commerce called for the resignation of the Police Chief. At the end of the month, ten thousand people marched in silent protest in New York City over the riots, which contributed to the radicalization of many.

[paraphrased from Wikipedia]

Do you know anything about the event described above? The above passage describes the East St. Louis race riot that occurred on Monday, July 2, 1917. I learned about this riot for the first time tonight when I had the opportunity to hear a talk by Harper Barnes, a St. Louis journalist who has recently written a book called Never Been a Time: The 1917 Race Riot That Sparked the Civil Rights Movement. [caption id="attachment_5419" align="alignright" width="150" caption="Harper Barnes - Photo by Erich Vieth"]Harper Barnes - Photo by Erich Vieth[/caption] In 1914, the first world war was heating up and so were the heavy industries. East St. Louis, Illinois, located right across the Mississippi River from St. Louis, Missouri, was the home of large aluminum and steel plants. To backtrack, through the 1910s, one-half million blacks who had resided in the rural South moved up to northern cities. Employers made use of these blacks as strikebreakers. The blacks certainly wouldn't have felt much loyalty toward the unions, because the white unions banned black workers.

Scandanavia’s non-believers

The NYT just published an article ("Scandanavian Nonbelievers, Which Is Not to Say Atheists") describing new research examining religious attitudes in Sweden and Denmark. Most of the people interviewed had been baptized and don't consider themselves to be "atheists." On the other hand, they aren't religious--they've simply moved on from religion:

[Researcher Phil] Zuckerman found what he terms “benign indifference” and even “utter obliviousness.” The key word in his description of their benign indifference is “nice.” Religion, in their view, is “nice.” Jesus “was a nice man who taught some nice things.” The Bible “is full of nice stories and good morals, isn’t it?”

Beyond niceness came utter obliviousness . . . “In Denmark,” a pastor told Mr. Zuckerman, “the word ‘God’ is one of the most embarrassing words you can say. You would rather go naked through the city than talk about God.”

My growing impatience with creationists: a side by side comparison of evolutionary biology and creationism

Over the past three years of writing for DI, I have discussed evolution with many creationists who have posted comments at this site. These exchanges have been good for me. They have forced me to think harder about exactly what it is that I understand about evolution and what evidence supports my understanding. These exchanges have also helped me to understand the concerns and mental gymnastics of creationists. I now find myself getting increasingly impatient with the creationists, however. It was initially interesting to banter with creationists because I enjoyed the challenge of trying to understand why they claimed the things they claimed. I’m now getting annoyed with these creationists arguments, and it mostly has to do with the refusal of creationists to acknowledge relevant scientific observations from the real world. My frustration also stems from the anti-scientific mindset of creationists. As a group, creationists refuse to argue even-handedly. They become skeptical only when it suits their immediate needs—they don’t apply skepticism equally both to their own claims and to the claims of those with whom they disagree. As a group, they scurry to find disingenuous arguments to support points that they actually learned in churches, not in science books. Many of them are consciously dishonest, and when you call attention to their obvious untruths, they try to change the subject. There are exceptions to this rule. There are some creationists who aren’t consciously being dishonest, but those creationists tend to be so incredibly ignorant of the principles of the scientific theory of evolution that they lack the ability to meaningfully criticize evolution. Their arguments are aimed at things that no competent scientist has ever claimed. For numerous excellent examples of this problem, see these videos by AronRa here and here. It is well-established that humans are susceptible to committing errors caused by the confirmation bias. We seek out evidence that supports our current beliefs. Scientists are imminently aware of this danger and they work hard to design experiments to counteract this bias. Creationists (who don’t even try to run experiments) excel at feeding their confirmation biases. They proudly exclude evidence that threatens their opinions. Creationists come to mind when I consider David Hume’s quote: “Reason is and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.” [A Treatise of Human Nature, (2nd Ed.), Book II, Part I, Section III (“Of the influencing motives of the will”) (1739)].

Incompetent people don’t realize that they are incompetent

Based on a new study reported by the NYT, people who do things badly

are usually supremely confident of their abilities -- more confident, in fact, than people who do things well.

Humor-impaired joke-tellers rated themselves as funny . . .

One reason that the ignorant also tend to be the blissfully self-assured, the researchers believe, is that the skills required for competence often are the same skills necessary to recognize competence.

It would seem, then, that you shouldn't ever ask someone whether they are good at what they do. This is a good reason to downplay the importance of oral interviews.
