The Fraud of Agriculture
Scholars once proclaimed that the agricultural revolution was a great leap forward for humanity. They told a tale of progress fuelled by human brain power.Evolution gradually produced ever more intelligent people. Eventually, people were so smart that they were able to decipher nature’s secrets, enabling them to tame sheep and cultivate wheat. As soon as this happened, they cheerfully abandoned the gruelling, dangerous, and often spartan life of hunter-gatherers, settling down to enjoy the ...22 MAR 2017 by ideonexus
Myths About Learning Quiz
True or false: When it comes to learning, metacognition (e.g., thinking about thinking) can be just as important as intelligence. RIGHT!

Abuse of Science in Politics
North Carolina provides a recent example of science-based policy. The science itself was a study of voting habits among the population of the state. In 2013, North Carolina passed new voting restrictions. To inform those restrictions, the legislature commissioned a study on voting habits by race, and then wrote into law a series of restrictions that specifically targeted African Americans. (Last month, a Federal Court struck down these restrictions, claiming that “the new provisions target ...02 SEP 2016 by ideonexus
Neil DeGrasse Tyson's Rationalia
In Rationalia, the Constitution stipulates that a body of convincing evidence needs to exist in support of an idea before any Policy can established based on it. In such a country, data gathering, careful observations, and experimentation would be happening all the time, influencing practically every aspect of our modern lives. As a result, Rationalia would lead the world in discovery, because discovery would be built into the DNA of how the government operates, and how its citizens think....08 JUL 2016 by ideonexus
Exercise Releases Brain-Healthy Proteins
We all know that exercise is important for a strong and healthy body. Less appreciated is that exercise seems also to be important for a strong and healthy mind, boosting memory and learning, while possibly delaying age-related cognitive decline [1]. How is this so? Researchers have assembled a growing body of evidence that suggests skeletal muscle cells secrete proteins and other factors into the blood during exercise that have a regenerative effect on the brain. Now, an NIH-supported study...23 MAY 2015 by ideonexus
Invisible Pink Unicorn
It is common when discussing the Invisible Pink Unicorn to point out that because she is invisible, no one can prove that she does not exist (or indeed that she is not pink). This is a parody of similar theistic claims about God—that God, as creator of the universe, is not subject to its laws and thus not physically detecting him tells us nothing about his existence or lack thereof. The Invisible Pink Unicorn is an illustration which attempts to demonstrate the absurdity of citing attribute...Folksonomies: secularism

Resveratrol and SIRT1
For the last decade, the science of aging has increasingly focused on sirtuins, a group of genes that are believed to protect many organisms, including mammals, against diseases of aging. Mounting evidence has demonstrated that resveratrol, a compound found in the skin of grapes as well as in peanuts and berries, increases the activity of a specific sirtuin, SIRT1, that protects the body from diseases by revving up the mitochondria, a kind of cellular battery that slowly runs down as we age. ...Folksonomies: longevity supplements

The Ability to Spell Correctly Should Not be Valued
Because the absurdities and intricacies of our pres- ent spelling hav made a mastery of them the most dif- ficult and long-continued task of the average student, a false value has been placed on spelling ability. "Cor- rectness" in reality, mere conformity in spelling is too generally assumed to be an indication of su- perior education, whereas as has been shown it is only evidence of a natural or a specially traind eye-memory.08 MAR 2015 by ideonexus
Professors Come from a Select Few Universities
The evidence is not only anecdotal. A recent study by Aaron Clauset, Samuel Arbesman, and Daniel B. Larremore shows that “a quarter of all universities account for 71 to 86 percent of all tenure-track faculty in the U.S. and Canada in these three fields. Just 18 elite universities produce half of all computer science professors, 16 schools produce half of all business professors, and eight schools account for half of all history professors.” This study follows the discovery by political s...03 MAR 2014 by ideonexus
Science and Democracy are Synergistic
The values of science and tha values of democracy are concordant, in many cases indistinguishable. Science confers power on anyone who takes the trouble to learn it. Science thrives on the free exchange of ideas; its values are antithetical to secrecy. Science holds to no special vantage points or privileged positions. Both science and democracy encourage unconventional opinions and vigorous debate. Both demand adeguate reason, coherent argument, rigorous standards of evidence and hones...The two concepts support one another.
