At what age did women get married in the 1970s?

November 17, 2017

An odd question motivated by recent events.

========

First the disclaimer, Judge Roy Moore creeps me out … and I’m certainly no apologist for older men who hit on teenage girls. Period.

That said, two comments got me wondering.

First, a Clinton apologist was on TV saying that Bill deserved a pass for his sexual transgressions and abuses because “things were different in those days.”

Say, what?  Different how?

Separately, a friend bad-quipped about the sterotype of Southern girls marrying young – often in their early teens.

So, I started to wonder: what were things like in “those days” – specifically,in Alabama, when Judge Moore is alleged to have been hitting on teenage girls.

What I discovered certainly doesn’t make Moore any less creepy or exonerate him, but it is interesting.

More Disney: How does Mickey fingerprint me?

November 16, 2017

The tech behind biometric fingerprints
========
Note: We’ve been doing an amusement park case in my current course.  So, we’re reprising a post from the archives.
=========

In prior posts, I gushed over the technology applications at Disney World … and recounted the plausible explanations for why Mickey digitally records guests’ fingerprints when then enter the park.

Ostensibly, the purpose is fraud protection – keeping folks from passing along their partially used tickets for reuse.

Of course, there are other sorts of uses for digital fingerprints (e.g. catching bad guys) … and ways that the information can be misused.

Seriously, why not outsource TSA ops to Disney?

November 14, 2017

Disney’s technology applications are impressive.
===========
Note: We’ve been doing an amusement park case in my current course.  So, we’re reprising a post from the archives.
============

Last Spring, I took a fact-finding trip (aka. family vacation) to Disney World.

I was amazed at the way that Disney uses technology.

My first “wow” was at the entrance gate.

No surprise, there was a huge rush of “guests” entering the Magic Kingdom when the gates opened at 8 a.m.

The crowd measured into the thousands … all needing to be security-screened.

All bags and strollers had to be hand-checked … all kids – big & little – had to be ushered through metal detectors.

Nightmare, right?

Maybe at the airport, but not at Disney.

Our wait & processing time: less than 10 minutes.

Facebook’s addictive dopamine hits “exploit a vulnerability in human psychology."

November 13, 2017

Co-founder admits: ‘God only knows what it’s doing to our children’s brains’

=========

Loyal readers know that I’m not a big fan of Facebook.

Besides the obvious privacy issues, I’ve been swayed by the mounting evidence that mental health deteriorates with heavy Facebook “engagement” … and that heavy Facebook engagement is becoming the norm … especially among teens.

So, I wasn’t surprised — but, I was shocked — when Sean Parker – one of Facebook’s co-founders – “unloaded on Facebook” … confirming many suspicions and bluntly admitting that it was all part of a master plan that may have “created a monster”.

How physically fit are folks in your city?

November 10, 2017

Washington, D.C. rated as “most fit city” for 3rd year in a row.

======

Every year, the American College of Sports Medicine and the Anthem Foundation rates the “fitness” of major metro areas based on a number of health behaviors and environmental factors such as access to parks, recreational facilities and walking trails.

According to this year’s  report, Washington, D.C. topped the list again.

=======

What makes D.C. so fit?

• Lower (than target) percent currently smoking
• Lower death rate for cardiovascular disease
• Higher percent of city land area as parkland
• Higher percent bicycling or walking to work
• More dog parks per capita
• More park units per capita
• More recreation centers per capita

And, my favorite:  More farmers’ markets per capita

Say, what?

D.C.’s score got a couple of dings including  a biggie: Fewer golf courses per capita

Studies: More time on Facebook … and it’s not good for you.

November 9, 2017

“Negatively associated with overall well-being … particularly mental health”.

=========

Let’s connect a couple of recently reported studies …

First, the BLS periodically reports how Americans spend their leisure time.

According to the NYT, channeling the most recent BLS report:

The average time that users spend on Facebook is nearing an hour.

clip_image002

Putting that hour of Facebook in perspective:

That’s more than any other leisure activity surveyed … with the exception of watching television programs and movies (an average per day of 2.8 hours).

It’s more time than people spend reading (19 minutes); participating in sports or exercise (17 minutes); or social events (four minutes).

It’s almost as much time as people spend eating and drinking (1.07 hours). NYT

========

And, a recent study published by the Harvard Business Review indicates that all that Facebook time is unhealthy.

Happy? Sad? Excited? … Facebook can tell.

November 8, 2017

And, has been caught doing just that.

=======

It always amazes me what people post on Facebook. Their daily activities, their deepest emotions – you name it.

By now, every Facebook user should know that FB sifts through their content – posts, pictures, links, emojis – to determine, for example, what topics are hot; what people are doing; which brands people are buying, recommending, trashing or considering; whether users are feeling happy, sad, scared, excited.

The latter is called “sentiment analysis” using computer algorithms to take users’ “emotional pulse”.

Of course, FB promises that they’ll protect users’ privacy and would never even consider divulging that information to outsiders, say, advertisers or political campaigns.

image

Bad news for believers: FB was caught “sharing” sentiment analysis data.

=========

According to USA Today

Documents leaked to a newspaper, The Australian, indicate that Facebook executives prepared a report for one of the country’s top banks.

The report described how Facebook gleans psychological insights into the mood shifts of millions of young people in Australia and New Zealand by monitoring their status updates and photos.

The 23-page report showed Facebook’s ability to detect when users as young as 14 are feeling emotions such as defeat, stress, anxiety or being overwhelmed … and. other information on young people’s emotional well-being such as when they exhibit “nervous-excitement” are “conquering fears“.

FB claimed that it can track how emotions fluctuate during the week.

Anticipatory emotions are more likely to be expressed early in the week.

Reflective emotions increase on the weekend.

Monday-Thursday is about building confidence.

The weekend is for broadcasting achievements.

At a relatively benign level, advertisers can use that information to target ads to certain age groups … and they can time them to run on a certain day.

That’s apparently what FB got caught doing – revealing anonymous and aggregated data – to a potential advertising client.

========

Let’s go a step further…

According to the article: “Facebook has also come under heavy scrutiny in the past for secretly conducting research that manipulated the emotions of users by altering what they see in their News Feed without their consent.”

So, it doesn’t take much creativity to imagine the collection and dissemination of individuals’ sentiment data that could be used to target advertising to specific individuals at specific times – say, when they’re feeling down and are vulnerable to buying certain products geared to giving them a pick-me-up, say, some new clothes, a fancy car or miracle drug.

Pretty unnerving, right?

Of course, FB assures users that it would never consider divulging that sort of data.

Yeah, right.

========

Connecting dots

In a prior post, we reported on a study that concluded time on Facebook can be hazardous to your mental health.

For details see Studies: More time on Facebook … and it’s not good for you.

So, being on Facebook can make you emotionally vulnerable.

Facebook can determine when you’re vulnerable.

Facebook can sell that info to advertisers.

But, FB assures us that it won’t sell that data.

Whew … that’s a relief.

Are you a nice person?

November 3, 2017

You probably over-rate your “niceness” … but that’s OK.

=======

According to the UK Independent

You may consider yourself to be a nice person, but  a new study concludes that you’re probably not as nice as you think.

Psychologists at the University of London have discovered that 98 per cent of British people think they’re part of the nicest 50 per cent of the population.

Participants in the study were given a list of “nice” behaviors and asked which ones they do.

They claimed to do easy stuff like giving directions to lost souls, holding doors open or giving Granny their seat on the bus.

clip_image002

But, their niceness had limits …

The respondents stopped short of giving money to needy strangers (less than 1 in 5) or helping Granny cross the street (about 1 in 4).

Still, there’s some very good news …

All of the info I’ve collected says I’m right … so there!

November 2, 2017

Dan Lovallo, a professor and decision-making researcher says, “Confirmation bias is probably the single biggest problem in business, because even the most sophisticated people get it wrong. People go out and they’re collecting the data, and they don’t realize they’re cooking the books.”

What’s this “confirmation bias” that Lovello is talking about?

No surprise, people tend to seek out information that supports their existing beliefs.

You know, liberals watch MSNBC, read the NY Times listen to BBC podcasts; conservatives watch FOX, read the WSJ and listen to Rush.

Behavioral psychologists call the he dynamic “confirmation bias”.

In socio-politics, the confirmation bias tends to harden polarized positions. People just gather debate fodder rather than probing both sides of issues.

In the realm of decision making, confirmation bias has a dysfunctional effect: it leads to bad decisions.

Should you put your extracurricular activities and interests on your resume?

November 1, 2017

More than you think, they may impact your chances of getting an interview.

=======

Interesting study reported in HBR

The study investigated whether applicants got invited to interview at highly prestigious law firms (though the findings are probably generalizable to other top-notch professional firms).

Here’s the drill:

Imagine four applicants, all of whom attend the same, selective second-tier law school.

They all have phenomenal grade point averages, are on law review, and have identical, highly relevant work experiences.

The only differences are whether they are male or female and if their extracurricular activities suggest they come from a higher-class or lower-class background.

Who gets invited to interview?

More specifically, the researchers used a technique — known as the resume audit method — randomly assigning different items to the resumes and sending applications to real employers to see how they affect the probability of being called back for a job interview.

All applicants were from 2nd tier schools (where top firms don’t typically do on campus interviewing).

All educational, academic, and work-related achievements were identical between the fictitious candidates.

To test gender effects, the applicants were first-named James or Julia.

To “signal” social status, last names were either prestigious sounding “Cabot” or more common “Clark” … and commonly used and and often required portions of resumes were varied: awards and extracurricular activities:

The experiment confirmed some expectations, but there were also surprises …

Michigan State University bans whiteboards … say, what?

October 31, 2017

This one gave me a false-positive flashback …

========

First, the flashback…

When we moved into our new business school building a decade ago (yeah, it has been that long), I was assigned a new office.

It was at the end of a corridor (as far away from the academic action as they could put me) with a clear view of the building’s commercially-sized air conditioners and the Jesuit graveyard (no kidding).

One complete wall in the office was floor-to-ceiling with book shelves.

Since I only had 6 books (5 of them borrowed), I took out all but the top book shelf (which was suitable for displaying memorabilia) and installed a self-purchased whiteboard (a necessity, right?).

clip_image002

In short order, I got visit from the Dean.

One of my colleagues had ratted me out for making an unauthorized alteration to my office.

Apparently, my whiteboard had violated some common law community standards.

I got off with a slap on the wrist (remember, Gtown is a Catholic school) … but still have occasional nightmares.

=======

OK, fast forward to today in Lansing, Michigan where whiteboards are now officially contraband.

Girl wins golf tourney … denied trophy.

Penalized for being a girl … say, what?

Let’s go to the Commonwealth of Massachusetts for this one.

According to reports, Emily Nash, an 8th grader, won a teen boy’s golf tournament.

As allowed by rules, she entered the tournament as part of her high school’s team (since girl’s don’t play fall golf in her school district).

She shot from the same tees as the boys.

And, she shot 75 … which was 4 strokes better than the 2nd place finisher.

Not bad, right?

It’s time to do away with SALT.

Among the provisions of the GOP’s tax-cutting plan that has drawn intense opposition (mostly from Democrats) is the elimination of state and local tax (SALT) deductions for folks who itemize their deductions (versus taking the standard deduction).

All else equal, eliminating the SALT deduction would income taxes paid to the federal government by about $180 billion each year … providing some wiggle room for cutting income taxes in other ways.

Gates, Zuckerberg … and the limits on educational philanthropy.

October 24, 2017

Both threw much money at education with disappointing results.

========

Two related reports hit over the weekend.

The first announced that the Gates Foundation would spend more than $1.7 billion over the next five years to pay for new initiatives in K-12 public education. The plan is a “redirection” of prior initiatives. More on that later.

As the Washington Post observed, Gates’ prior mega-contributions to improve K-12 education “didn’t go so well, but the man, if anything, is persistent.”

clip_image002

The second story dealt with Mark Zuckerberg’s $100 million donation to improving Newark NJ’s schools. A report was released indicating disappointing results. More on that later, too.

========

I commend both Gates and Zuckerberg for throwing a massive amount of money at improving education. Their intentions seem good and the amounts of money are, as we say in academia, statistically significant.

Interesting study reported in The Atlantic

A pair of psychologists – Betty Hart and Todd Risley –  got curious about why some 3 and 4 year old kids are more academically ready than others.

“They devised a novel (and exhaustive) methodology: for more than three years, they sampled the actual words spoken to young children from 42 families at 3 different socioeconomic levels: (1) welfare homes, (2) working-class homes, and (3) professionals’ homes. Then they tallied the quantity and quality of the words spoken to the kids. “

How much does “healthcare” really matter?

October 16, 2017

For a long time I’ve railed that politicos and pundits confuse “healthcare” with “health insurance” – trying to fix health insurance (by throwing money at it) … rather than getting to the efficacy and efficiency roots of healthcare delivery.

Here’s another twist to the story.

I stumbled on a report from the Kaiser Foundation: Beyond Health Care: The Role of Social Determinants.

It’s punch line:

“Though health care is essential to health, research demonstrates that it is a relatively weak health determinant.”

More specifically, Kaiser concludes that healthcare has only about a 10% impact on the risk of premature death … dwarfed by genetics (30%) and individual behavior (40%).

Said differently, health behaviors, such as smoking and diet and exercise, are the most important determinants of premature death

clip_image002

And, as the title of the article’s title suggest, there’s a social component (20%) that’s double the impact of healthcare per se …

Fun fact: another apparent partisan divide …

Yesterday, we posted a Pew survey finding:

“Each party has become more ideologically homogeneous, and more hostile toward the opinions of members of the other party.”

Oh, my.

On a slightly lighter side, the nation is even divided on housing preferences:

“Overall, Americans are equally divided between wanting to live in a community with larger houses farther apart, where schools, shops and restaurants are not nearby (48%), and those who want to live in smaller houses closer together but within walking distance to schools and shops (47%).”

College: Making Freshman year (almost) free …

Let more students earn AP credits by putting “boilerplate” courses online and beefing-up certification testing.

A article posted on Real Clear Politics caught my eye.

The author Steven Klinsky, is credentialed as a businessman and education reformer, chairman of Harvard’s Public Education Policy Group and founder of the Modern States Education Alliance (MSEA).

He observes that (1) traditional brick & mortar colleges are increasingly unaffordable, (2) that “the tuition cost for many online courses has been set every bit as high (or sometimes higher!) than for the same course delivered in the physical classroom” and (3) that increasingly popular MOOCs can deliver quality content but no college credits—just “certificates of completion”.

So, as a private citizen and philanthropist, Mr. Klinsky has been trying to “square the circle” with MSEA’s “Freshman Year for Free” program.

Memo to Michelin: Shove your stars …

3-star chef wants out of the rankings

==========

According to the NY Times

Sébastien Bras, one of France’s most celebrated chefs, has stunned the French culinary world with an unlikely plea: Take my three Michelin stars away.

Mr. Bras is fed up with the pressure of maintaining those stars. He says he is seeking nothing less than culinary “liberation” and “a new meaning to my life.”

While the stars confer cachet and financial security, Mr. Bras’s audacious move is also reflective of a new generation of chefs, some of whom are eager to escape from the punishing strain of unpredictable rankings and malicious food critics.

“Three stars mean that everything must be perfect, at any time, in every plate. One must be passionate, a genius, but mostly a workaholic, because you have to be working in your restaurant from 7 a.m. to 2 a.m. every day, nonstop.”

There’s also an economic angle …

To put it mildly, the dogs stopped eating the dog food.

As reported in the WSJ

In early 2015 General Mills reformulated iconic Trix cereal to make it all-natural – replacing Red Dye #40, Blue Dye #1 and Yellow Dye #6 with radishes, purple carrots and turmeric.

Besides producing a bland color, the juices and extracts gave the cereal a different taste.

Natural-ingredient haters flooded the company with calls, emails and social-media posts:

“I genuinely feel bad that my kids will never got to experience the old Trix cereal.”

“My kids think the color of the new Trix cereal quite depressing.”

“It’s basically a salad now.”

“My childhood fading away with the colors of Trix cereal.”

“Americans’ love affair with processed foods is enduring, however, despite a decade of finger-wagging from nutritionists, influential celebrities and trendy grocery chains.”

So, General Mills has decided to reintroduce Classic Trix, artificial flavorings and all, and will start selling it on supermarket shelves alongside the more wholesome version in October.

Answer: Are you smarter than a 10th grader?

September 25, 2017

Here’s the ANSWER to to last week’s math challenge

=========

Last week, we touted Chicago’s Noble Network of Charter Schools … specifically, its intensive math curriculum

And, we presented a challenge question (taken from the 10th grade curriculum) …

==========

Noble Charter HS – Math Challenge Question

The rectangle shown below is divided into four green squares, seven gold squares, four orange squares, and one blue rectangle.

If the perimeter of the blue rectangle is 20 cm, what is the perimeter of the larger rectangle?

Explain your reasoning.

Question: Are you smarter than a 10th grader?

September 22, 2017

A math success story … and a challenge (for you).

==========

Earlier in the week, we posted results of a report ranking U.S. high school students #40 in math literacy among developed nations.

A friend reminded me that those are averages … and there are some bright lights.

One such bright light is shining at Chicago’s Noble Network of Charter Schools.

Noble is comprised of a growing network of high quality public high schools located in Chicago’s communities of greatest need.

Noble has 18 campuses educating 12,000 students.

True to its mission, 98% of the students are minorities and 89% low income.

Here’s the kicker …

According to Stanford’s Center for Research on Education Outcomes:

Students at The Noble Network of Charter Schools receive the equivalent of nearly two years’ worth of math in each single year. Source

What kind of math are they working on?

Here’s a problem from the 10th grade curriculum …. try it.

How much of an “iGen” are you?

September 21, 2017

There’s a whole new generation out there, folks.

=========

In yesterday’s post, we highlighted iGen – a recent book by Jean Twenge – a psychology prof specializing in “generational research”.

Millennials  are yesterday’s news.

The new generation is iGen – born after the introduction of the Internet … and now living connected to their iPhones.

Prof. Twenge observes that the cultural and personal impacts of the “i” technology revolution are a mixed bag – some good and some bad.

More on that in later posts.

Disruptive innovation: How the iPhone has shaped a new generation.

September 20, 2017

A new book says that not all of the “shaping” has been good.

============

A week or so ago, when Apple celebrated the 10th Anniversary of the iPhone and launch of iPhone X, CEO Tim Cook boasted:

Having sold over one billion units and enabling millions of apps that have become essential to people’s daily routine …

The iPhone redefined how consumers live, work, communicate, and entertain.

I chalked it up as marketing hype, but then …

I started reading a recently released book (coincidence?) called iGen: Why Today’s Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy–and Completely Unprepared for Adulthood.

The author is Jean Twenge, a psychology prof with a specialty in “generational differences” who is credited with coining the newest generation “iGen”.

Prof Twenge agrees with Cook’s basic claim that the iPhone has redefined life.

But, she argues, not all of the redefinition is positive … specifically highlighting the decline in in-person social interaction and a sharp rise in mental health issues among iGens.

Let’s start at the beginning ….

More distressing news on the math front …

September 19, 2017

Last week, we praised algebra, logic and Latin as basic learning skills.

In praise of math, logic, and Latin … say, what?

Yesterday, we reported that U.S. high schoolers math scores are continuing to drop … and that the U.S. now ranks #40 among developed countries.

Ouch: U.S. math scores continue to drop

Now there’s discouraging news out of California: Algebra is under siege.

clip_image002

In 2009, the California Community Colleges system began requiring demonstrated math competency at the level “typically known as Intermediate Algebra … or another mathematics course at the same level, with the same rigor.”

What was the result, and what do educators plan to do about it?

Ouch: U.S. math scores continue to drop

September 18, 2017

U.S. now trails 39 countries …

=========

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.

Do you carry your iPhone in your pocket?

September 15, 2017

Frequently causes a problem  … with an easy fix

==========

I was at near-panic stage a couple of night’s ago.

I tried to insert my battery charger into the lightning connector port (pictured below) like I always do … but it wouldn’t go in all the way and the phone wouldn’t charge.

 

image

Oh no.

What to do?

First I tried another charger cable … figured that might be the problem since I sometimes buy accessories from OEMs instead of Apple.

No luck.

Then started to wonder where to take it for repairs:  Verizon (where I bought it)? Apple store (since it’s a iPhone)?

Concluded that it would be an out-of-warranty repair at the Apple store.

That can’t be good.

Then I decided to Google the problem …

Free college for all?

September 14, 2017

Idea falls flat with voters

=========

Interesting article in left-leaning Politico: Teflon Don confounds Democrats

Based on research, conducted by private firms and for Democratic campaign arms, Politico analysts have concluded:

Democrats tried attacking Donald Trump as unfit for the presidency. They’ve made the case that he’s ineffective. They’ve argued that Trump is using the presidency to enrich himself. They repeatedly claim that his campaign was in cahoots with Russia. None of it is working.

image

And, many of the proposals Democrats are pushing fall flat in focus groups and polling.

Many of the ideas party leaders have latched on to in an attempt to appeal to their lost voters — free college tuition, raising the minimum wage to $15, even Medicaid for all — test poorly among voters outside the base.

Of course, the results re: free college tuition caught my eye …

#11 – Why I’m lukewarm to climate change…

September 13, 2017

Reason #11 – Celebs who “never let a serious crisis go to waste.”

=========

For the record: I’m neither a denier nor a zealot …  so, according to British writer (& phrase-coiner) Matt Ridley, I’m a “lukewarmer”.

And, I’ve personally had the eyes of 2 hurricanes literally pass right over my house, so I’m aware of their devastating potential.

I have friends and family in Houston and scattered around Florida. They and other hurricane victims have my deepest sympathy.

Moving on …

========

Earlier in the summer, I posted a series The 10 reasons why I’m lukewarm to climate change…

Last night’s celebrity phone-a-thon for Harvey & Irma victims prompts me to add to the list.

======

Reason #11- Celebs who ““Never let a serious crisis go to waste.”

The quote is generally attributed to Rahm Emmanuel – former of Obama chief-of-staff and currently Mayor of murder- riddled Chicago.

Last night, the credo was put into action.

At 8 o’clock, I tuned in the see the semi-finals of my favorite TV show: America’s Got Talent.

Imagine my disappointment when I saw that the show was being delayed (to past my bed time) for a celebrity fund-raiser.

OK, I figured … let’s watch an hour of pros sing and dance.

Cue the first act: Little Stevie Wonder … err, I mean Stevie Wonder … err again, I mean Steven Wonder … whatever.

clip_image002

Pre-ambling his ditty, Mr. Wonder preached:

“It just loves. As we should begin to love and value our planet.”

So far, so good.

Then the pivot:

Anyone who believes that there is no such thing as global warming must be blind or unintelligent.”

He made a lightning-fast pivot from the hurricane disasters to climate change.

Conveniently, ignoring a few facts …

Is financial stress making Americans dumber?

September 12, 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.

In praise of math, logic, and Latin … say, what?

September 11, 2017

Classical educators argued that these disciplines are the building blocks of reasoning, problem-solving and critical thinking.

=======

The courses that I teach contain a heavy dose of problem-solving skills.

Early on, I assert my belief that that problem-solving skills can be taught – and, more importantly, learned – and set about to prove the point.

=======

I’ve been doing some summer reading on the topic of reasoning & problem-solving and learned:

“For twenty-six hundred years many philosophers and educators have been confident that reasoning could be taught.”

There are 5 clues of “authentic” intelligence …

September 8, 2017

For openers, high IQ and bilingual aren’t on the list.

Interesting piece that I spotted on the DailyMail

Everybody tries to act smart, right?

You know … long words, dramatic pauses, furled brows, grasped chins.

Psyche researchers dismiss most of these antics as shallow fakery and have identified 5 behavioral traits that authentically mark true intelligence.

Test yourself ….and start using the markers to smoke out faux-smarties.
