Tell me again why Duncan was good, but charter-advocate DeVos is bad …

February 8, 2017

Math scores dropped since 2009 … U.S. now trails 39 countries.

Strikes me that Duncan is an easy act for DeVos to follow as Education Secretary..

=========

The Program for International Student Assessment (PISA) recently released its 2015 survey results for math “literacy” … and, the results aren’t pretty.

The average for 15-year-old U.S. students slipped to 470 on the PISA scale … down about 3.5% from 2009 … ranking the U.S. #40 among developed nations (see list at end of this post) … 20 points lower than the average of the 35 OECD (Organization for Economic Co-operation and Development) countries.

The scores differential versus the OECD countries is roughly equal for the average, 25th percentile and 90th percentile … refuting claims that “our” best are head-to-head competitive with the the rest of the world’s best.

Is financial stress making Americans dumber?

January 27, 2017

Connecting some research “dots” suggests that may be the case.

======

A recent Bankrate.com survey says that 40% of respondents or their immediate family ran into a major unexpected expense last year.

image

That’s a problem since most Americans (63%) don’t have enough budget-cushion or savings to cover an unexpected $1,000 expense (think, medical bill, house or car repair).

According to the poll, only 37% said they would be able to take the money directly from savings; the rest said they would try to cut expenses (24%), use their credit cards (15%) or borrow money from friends & family (15%). About 1 in 10 had no idea what they’d do.

Predictably, those with higher incomes were most likely to say they would be able to tap savings for emergencies or divert some discretionary spending.

75% of people in households making less than $50,000 a year and 2/3s of those making between $50,000 and $100,000 would have difficulty coming up with $1,000 to cover an unexpected bill.

Even for the wealthiest 20% — households making more than $100,000 a year — more than 1 in 3 say they would have  some difficulty coming up with $1,000. Source

======

Obviously, the threat of a large, unexpected expense is emotionally daunting to most Americans.

“It definitely adds stress to everyday life. It hangs over you.”

To make matters worse, there is some evidence that the financial stress may impair “cognitive functioning” – that is, dent a person’s IQ.

Maybe we’re just not that smart …

January 13, 2017

Yesterday, we reported that the U.S. is, on average, #40 in the world in mathematics.

Usual punditry is that schools are bad … blame it on the teachers.

But, I wondered: is it a bad production process (the schools) … or could it be the raw material going into the process (i.e. innate brain power).

So, the question of the day: how does the U.S. rank on IQ versus other countries?

Ouch: U.S. math scores continue to drop

Maybe Hillary should run for governor of California … here’s why.

December 16, 2016

She landslided California, but lost the combined popular vote in the other 49 states (& DC).

========

Dems are still carping that Trump’s ascendency is illegitimate since Hillary won the popular vote.

And, everybody knows that Hillary won big in California.

But, I was a bit surprised by how big her California win was … and its implications.

Bottom line: Clinton won the national popular vote by 2.8 million votes … buoyed by a 4.3 million edge in California.

Think about that for a second.

image

======

Yes, Clinton won California big time … but, Trump won the combined popular vote  of the other 49 states (& DC)

The MSM repeatedly observes that Trump followers drag their knuckles … and that Hillary dominated among the intelligensia.

So was Clinton’s success in California simply explained by Californians being smarter than the rest of the country?

Quick quiz: how does the average Californian’s IQ rack up against residents of other states?

The answer may surprise you ….

IQ scores are rising … here’s why.

June 21, 2016

Simple hypothesis: more folks are reading the Homa Files.

A more complex answer is offered by James Flynn is his book “Are We Getting Smarter? Rising IQ in the 21st Century”.

Shocker: Women are brighter and more clever than men …

June 20, 2016

According to UK’s Daily Mail

Recent IQ research indicates that women are brighter than men … more clever … and better at multi-tasking.

Since IQ testing began a century ago, women have been as much as five points behind.

image

But that gap has been narrowing in recent years and this year women have moved ahead.

In the last 100 years the IQ scores of both  men and women have risen but women’s have risen faster.’

Women are cleverer than men.

One indication: they’re better at multi-tasking.

I’ve often said that the Lord shouldn’t have taken that 7th day off … she still had some work to do designing us guys.

Even if you’re smart, you might not be logical …

October 16, 2014

Jacked from researchers at the Univ. of Toronto …

“Although intelligence as measured by IQ tests is important, so is the ability to think rationally about problems.

The surprise is that less intelligent people usually perform just as well as highly intelligent people on problems that test rationality.”

Below is a question to test if you’re a rational (i.e. logical) thinker … or just smart

image


Question

The XYZ virus causes a disease in one in every 1,000 people.

A test always correctly indicates if a person is infected.

The test has a false-positive rate of five per cent.

In other words, the test wrongly indicates that the XYZ virus is present in five per cent of the cases in which the person does not have the virus.

What is the probability that an individual testing positive actually has the XYZ virus?

Answer

Most people say 95 % … but the answer is 2%.

If one in 1,000 people has the disease, 999 don’t.

But with a five per cent false-positive rate, the test will show that almost 50 of them are infected (5% X 999 = 49.95 = approx. 50).

Of 51 patients testing positive, only one will actually be infected.

And, 1 divided by 51 is about 2%

“The math here isn’t especially hard. But thinking the problem through is tricky.”

IQ scores are rising … here’s why.

October 3, 2012

Simple answer: more folks are reading the Homa Files.

A more complex answer is offered by James Flynn is his book “Are We Getting Smarter? Rising IQ in the 21st Century”.

Here’s an excerpt from the WSJ review

image

* * * * *

From the early 1900s to today, Americans have gained three IQ points per decade.

In 1910, scored against today’s norms, our ancestors would have had an average IQ of 50 to 70.

Our mean IQ today is 130 to 150, depending on the test.

Our ancestors weren’t dumb compared with us, of course. They had the same practical intelligence and ability to deal with the everyday world that we do.

Our lives are utterly different from those led by most Americans before 1910.

The average American went to school for less than six years and then worked long hours in factories, shops or agriculture.

The only artificial images they saw were drawings or photographs.

Aside from basic arithmetic, nonverbal symbols were restricted to musical notation (for an elite) and playing cards.

Their minds were focused on ownership, the useful, the beneficial and the harmful.

Rising IQ scores show how the modern world, particularly education, has changed the human mind itself and set us apart from our ancestors.

Our ancestors lived in a much simpler world, and most had no formal schooling beyond the sixth grade.

Modern people do so well on these tests because … we are the first of our species to live in a world dominated by categories, hypotheticals, nonverbal symbols and visual images that paint alternative realities.

A century ago, people mostly used their minds to manipulate the concrete world for utilitarian advantage.

Our minds now tend toward logical analysis of abstract symbols.

Today we tend to classify things … take the hypothetical seriously …and easily discern symbolic relationships.

Since 1950, there have been large gains on vocabulary and information.

More words mean that more concepts are conveyed.

More information means that more connections are perceived.

Better analysis of hypothetical situations means more innovation.

A greater pool of those capable of understanding abstractions, more contact with people who enjoy playing with ideas, the enhancement of leisure— all of these developments have benefited society.

Our mental abilities have grown, simply enough, through a wider acquaintance with the world’s possibilities.

Thanks to AR for feeding the lead.
