RePost: How to Solve Problems

In Cultural Literacy E.D. Hirsch discusses the importance of a wealth of shared background knowledge in teaching in learning. “The more you know, the more you can learn.” He argues that as you acquire information—even through simple memorization—you create frameworks, or “schemata”, for integrating future learning. The more schemata you possess, the less effort is required to integrate new information, making it easier to learn overall.

It follows that there is great benefit to having a diversified set of schemata; the more subjects we know, the easier it is to learn. This is part of the basis for liberal education.This diversified set not only allows us easier access to broad knowledge, it also allows us to make connections that we wouldn’t have otherwise made, and understand things in different (and sometimes unusual) ways.

RePost: Secondhand Smoke Stole My Wallet

pickpocketI love reading Michael Crichton’s speeches about science and global warming. He blows me away. recently I’ve been reading “Aliens Cause Global Warming“, which has a lot to say about scientific “consensus” and junk science. Included is this statement about secondhand smoke:

In 1993, the EPA announced that second-hand smoke was “responsible for approximately 3,000 lung cancer deaths each year in nonsmoking adults,” and that it ” impairs the respiratory health of hundreds of thousands of people.” In a 1994 pamphlet the EPA said that the eleven studies it based its decision on were not by themselves conclusive, and that they collectively assigned second-hand smoke a risk factor of 1.19. (For reference, a risk factor below 3.0 is too small for action by the EPA. or for publication in the New England Journal of Medicine, for example.) Furthermore, since there was no statistical association at the 95% confidence limits, the EPA lowered the limit to 90%. They then classified second hand smoke as a Group A Carcinogen.

This was openly fraudulent science, but it formed the basis for bans on smoking in restaurants, offices, and airports. California banned public smoking in 1995. Soon, no claim was too extreme. By 1998, the Christian Science Monitor was saying that “Second-hand smoke is the nation’s third-leading preventable cause of death.” The American Cancer Society announced that 53,000 people died each year of second-hand smoke. The evidence for this claim is nonexistent.

Misusing Binet

Alfred Binet: Inventor of Intelligence

Alfred Binet: Inventor of Intelligence

Alfred Binet, a self-taught psychologist, created the scale which is now one of the best known measures of intelligence. In 1904 a French child psychology society began looking into determining which students would qualify for special education, and Binet – who had “published more than 200 books, articles, and reviews in what now would be called experimental, developmental, educational, social, and differential psychology” – responded the government’s appointment of the society to develop a measure by creating his scale.

According to a teacher’s resource provided by Indiana University, Binet made it clear that “intellectual development progressed at variable rates, could be impacted by the environment and was therefore not based solely on genetics, was malleable rather than fixed, and could only be used on children with comparable background.” But his test and scale soon made it into the hands of Henry H. Goddard, an American eugenicist.

Goddard was among many at the time who, like Francis Galton, believed that the best way to raise national averages in health and intelligence would be to prevent the “feeble-minded” and others not up to their standards from reproducing. Methods of included contraception, forced sterilization, and abortion. “Eugenicists claimed IQ tests could quantify innate human ability in a single measurement, despite the objections of the tests’ creator, Alfred Binet.[Wiki]

The test has now come to be used on a single scale for people from all cultures and socioeconomic backgrounds around the world. The test was never meant to compare even children from the same neighborhood from different economic classes, yet it is being used to compare Aborigines to European aristocrats.

It’s clearly time that a new standard for intellectual measure be developed, the only question is whether the reward will be greater to create it, or prevent it.

Physicalism in Science (Updated)

Physicalism: the metaphysical position that everything which exists has a physical property; that is, that there are no kinds of things other than physical things.

While contemplating the opening salvo of The God Delusion, I started thinking about the ideas of naturalism, materialism, and physicalism in relation to the scientific search to disprove the existence of God. After a while something was nagging at me…it just didn’t fit, logically.

Many people argue that the basis for Christian belief is circular. See Ryan’s second comment on my God Delusion chapter one post. The explanation I’ve heard most often is that the Bible says God is real, and since the Bible says it’s God’s word, it’s true. If all you’re basing your belief on is blind acceptance that the Bible is the truth, then it is quite circular.

But it finally clicked for me yesterday that this crusade undertaken by Richard Dawkins and many other scientists, to effectively disprove the existence of God through science is equally circular. Read more
