How to Dispel Your Illusions

A book review of "Thinking, Fast and Slow, author -Daniel Kahneman " written by Freeman Dyson



Cognitive illusions are the main theme of his book. A cognitive illusion is a false belief that we intuitively accept as true. The illusion of validity is a false belief in the reliability of our own judgment.

LA Review of Books: The Educational Lottery by Steven Brint

On the four kinds of heretics attacking the gospel of education. "In short, we will need to turn our backs on assumptions of our most fervent boosters of universal higher education: that access alone is the primary purpose, and that when students and teachers are co-present, education occurs. The challenge will be to reweave the uneven and tattered undergraduate experience in more durable and vivid patterns."

Politics, Pizzas and Pessimism

Amplify’d from www.nytimes.com


The disconnect between the seriousness of our angst and the silliness of our politics — between how big our problems are and how hopeless or just plain stuck the people who are supposed to address them seem — defies belief. Right now the system isn’t working, and a recognition of that is one of the ties that bind Occupy Wall Street and the Tea Party. They don’t identify the same villains or promote the same solutions. But they’re flowers of a shared frustration.

The Path Not Taken

But a funny thing happened on the way to economic Armageddon: Iceland’s very desperation made conventional behavior impossible, freeing the nation to break the rules. Where everyone else bailed out the bankers and made the public pay the price, Iceland let the banks go bust and actually expanded its social safety net. Where everyone else was fixated on trying to placate international investors, Iceland imposed temporary controls on the movement of capital to give itself room to maneuver.

Global Warming May Push Seaweeds Over the Edge

Amplify’d from www.livescience.com
Australian seaweeds are threatened by global warming.



Continued warming in the oceans around Australia could have dramatic effects on the seaweed that live in these waters, pushing their ranges south, and eventually, off the continental shelf. Changes in seaweed communities could have dramatic effects on other living things, since seaweeds provide habitat and food. Above, the Australian seaweed Pterocladia retangularis.

Is ‘complexity’ the key to economic growth?

Amplify’d from www.washingtonpost.com




Is ‘complexity’ the key to economic growth?

Meanwhile, if Hausmann and Hidalgo’s theory is actually right, then the future looks relatively limp for the United States. The authors note that the best way to predict a country’s future growth is to look at the gap between economic complexity and current earnings. On this score, China, India and Thailand have the highest expected growth in the years ahead. The United States, by contrast, ranks 91st. Economies that have already taken full advantage of their existing complexity, like the United States, have few remaining opportunities to move up further. This sounds unduly pessimistic, though it jibes pretty well with Tyler Cowen’s “great stagnation” thesis.

Trends in the Distribution of Household Income Between 1979 and 2007

Amplify’d from www.cbo.gov

CBO finds that, between 1979 and 2007, income grew by:


  • 275 percent for the top 1 percent of households,

  • 65 percent for the next 19 percent,

  • Just under 40 percent for the next 60 percent, and

  • 18 percent for the bottom 20 percent.

homepage graphic

The share of income going to higher-income households rose, while the share going to lower-income households fell.


  • The top fifth of the population saw a 10-percentage-point increase in their share of after-tax income.

  • Most of that growth went to the top 1 percent of the population.

  • All other groups saw their shares decline by 2 to 3 percentage points.

Actually Tax Cuts Don't Seem to Have Much Impact on Economic Growth...

Amplify’d from www.huffingtonpost.com

My point, and I do have one -- is that ideology is a poor substitute for pragmatic approaches to complicated problems. In fact the evidence that tax rates influence economic growth in any way is equivocal at best. A myriad of other factors are involved. Simply reducing tax rates, and primarily for the wealthy, may hinder -- rather than enhance our economic recovery.

A Generation of CEOs Who Don't Know How to Raise Wages

Amplify’d from www.huffingtonpost.com

This inability to raise wages is also reflected in the data. There is no major occupation group that has seen substantial increases in real wages over the last decade. Even college graduates as a group (excluding those with a post-graduate degree) have not seen an increase in real wages over the last decade. This indicates either there is no problem of skills shortages or that companies are increasingly being run by CEOs who do not know how to increase wages.

Safety Regulators Don’t Add Costs. They Decide Who Pays Them.

...many of those who insist on cost-benefit analysis have no interest whatsoever in making regulation more focused and rational. In their world, costs to business are the only measure; benefits to consumers somehow never make it to the table. Unfortunately, that’s misleading and unfair. Someone always pays.

Amplify’d from www.nytimes.com


Anyone who insists that regulations necessarily impose new costs on society shouldn’t be taken seriously. The costs are already there, in the form of deaths and injuries — and are often as much of a drag on our economy as any safety rule. So the real issue is who should bear the costs.

Waterboarding

Is "simulated drowning" - drowning someone "not enough to kill them"? How is the art of this skill acquired? If the subject is "not dead" then what effects are expected? [] "...causing an almost immediate gag reflex and creating the sensation that the captive is drowning. Waterboarding can cause extreme pain, dry drowning, damage to lungs, brain damage from oxygen deprivation, other physical injuries including broken bones due to struggling against restraints, lasting psychological damage and, if uninterrupted, death. Adverse physical consequences can manifest themselves months after the event, while psychological effects can last for years." []

Rabbit-Hole Economics

Amplify’d from www.nytimes.com


The Great Recession should have been a huge wake-up call. Nothing like this was supposed to be possible in the modern world. Everyone, and I mean everyone, should be engaged in serious soul-searching, asking how much of what he or she thought was true actually isn’t.


But the G.O.P. has responded to the crisis not by rethinking its dogma but by adopting an even cruder version of that dogma, becoming a caricature of itself. During the debate, the hosts played a clip of Ronald Reagan calling for increased revenue; today, no politician hoping to get anywhere in Reagan’s party would dare say such a thing.


It’s a terrible thing when an individual loses his or her grip on reality. But it’s much worse when the same thing happens to a whole political party, one that already has the power to block anything the president proposes — and which may soon control the whole government.

Lake Erie's Toxic Algae Bloom Seen From Space: Green Scum Rampant In The Great Lakes (PHOTOS)

While the algae doesn't directly kill fish, it's still not good. As the algae dies, it's broken down by bacteria which uses oxygen from the water. This oxygen removal creates areas where fish can't survive. In addition, if consumed, it can also create flu-like symptoms in people or even kill pets.

What Parkinson’s Teaches Us About the Brain

Amplify’d from well.blogs.nytimes.com

Why forced exercise would have a greater effect on brain functioning than gentler regimens isn’t clear. Scientists have speculated that in animal experiments, being forced to work out may cause the release of stress-linked hormones in rodents’ brains, which then prompt various reactions in the cells and tissues. But Dr. Alberts suspects that in Parkinson’s patients, the answer may be simple mathematics. More pedal strokes per minute cause more muscle contractions than fewer pedal strokes, which, in consequence, generate more nervous-system messages to the brain. There, he thinks, biochemical reactions occur in response to the messages, and the more messages, the greater the response.
