 Rational Ignorance

Of course, it is a cliché of our times that we suffer from information overload because of the ubiquity of electronic media. And for fifty years, cognitive scientists have been harping on the limitations of the brain in processing information. Some have argued that Grice’s cooperative maxims are a way to manage the flow of information in a conversation, maximizing the rate of transmission of usable knowledge. But the ultimate reason our speech is so indirect may lie in a different danger ...

 Rolling Triggers and Social Multipliers Explain the Flynn...

The most potent facet of our environment is other people. When something, perhaps the popularity basketball got from television, triggered greater participation in basketball, the average performance rose as individuals played more and got better. Initially, a few people learn to shoot with either hand, then others imitate them. The rise in average performance feeds back into a new challenge for each individual. Those who want to excel have to learn to pass with either hand and this spreads a...

 Flynn-Dickens Model for IQ Gains

Take those born with genes that make them a bit taller and quicker than average. When they start school, they are likely to be a bit better at basketball. The advantage may be modest but then reciprocal causation between the talent advantage and environment kicks in. Because you are better at basketball, you are likely to enjoy it more and play it more than someone who is bit slow or short or overweight. That makes you better still. Your genetic advantage is upgrading your environment, the am...

If g-factor is inherited, then how do we explain the Flynn Effect? This model suggests genetic advantages translates into environmental advantage, the environment feeds back to become more challenging.

 An Algorithm for Predicting Longevity

For the test, participants exercised on a treadmill at increasing speed and incline. While they were exercising, the researches measured peak heart rate (%MPHR) and their ability to withstand physical exertion. On that latter point, they measured metabolic equivalents, or METs, which gauges how much energy the body expends during exercise. The more intense the exercise, the higher the METs (e.g. slow walking = ~2 METs, whereas running = ~8 METs). [...] FIT Treadmill Score = %MPHR 12(M...

You can get your MPHR for your age here. I found a chart of METS here for various exercises.

Activity METS Activity METS
Aerobic Dancing 6.0 Running 12 min/mile 8.5
Backpacking 7.0 Racquetball 8.0
Badminton 7.0 Rugby 8.3
Basketball 6.0 Skating ice/roller 7.0
Bicycling - 24mph 5.0 Skiing cross country 8.0
Calisthenics 4.5 Soccer 8.0
Golf 5.0 Softball 5.0
Gymnastics 5.5 Swimming 6.0
Handball 8.0 Tennis 7.0
Hockey 8.0 Volleyball 4.0
Horse riding 3.5 Walking 3.5
Running 8 min/mile 12.5 Weight lifting 4.5

Bruce Protocol

Stage Minutes % grade km/h MPH METS
1 3 10 2.7 1.7 5
2 3 12 4.0 2.5 7
3 3 14 5.4 3.4 10
4 3 16 6.7 4.2 13
5 3 18 8.0 5.0 15
6 3 20 8.8 5.5 18
7 3 22 9.6 6.0 20

Total Durations = 21 minutes

So, if I'm understanding this correctly. If I reach a 160 heart rate out of 179.0 MPHR predicted for my 41 years of age while running 12 minute miles worth 8.5 METS. My score would be:

83.7 12(8.5) - 4(41) = 21.7

The same heart rate for my age running 8 minute miles:

83.7 12(8.5) - 4(41) = 69.7

 How Coaches and Teachers Differ

Traditionally, coaches and teachers operate quite differently when working with groups of children. Coaches tend to teach for success. For example, suppose a coach is teaching the skill of dribbling a basketball. He or she first shows the children exactly what good, proper dribbling looks like. The demonstration may then be expanded by showing some exceptional, fancy-footwork-type dribbling that the kids may aspire to learn with extra effort. The coach shows common errors made when dribbling ...

Coaches encourage learning through collaboration and practice, while teachers make the mistake of focusing on testable results and 'fairness.' Coaching seems like the preferable strategy.

 The Sacrifices Necessary to be a Sports Star

But it’s better for us not to know the kinds of sacrifices the professional-grade athlete has made to get so very good at one particular thing... the actual facts of the sacrifices repel us when we see them: basketball geniuses who cannot read, sprinters who dope themselves, defensive tackles who shoot up with bovine hormones until they collapse or explode. We prefer not to consider closely the shockingly vapid and primitive comments uttered by athletes in post-contest interviews or to cons...

A disturbing revelation. Possibly an overstatement or anecdotal, but the idea that total devotion to kinesthetic intelligence comes at the cost of other forms of intellect makes sense.

 Teaching a Child About Death

My dad used to take naps next to my daughter on the bed and I remember seeing them in there—my father with his oxygen machine and my daughter curled up next to him—and it was all so dreamy and loving and cute. And so, it was a big deal when he died. And my daughter had questions. When she asked “What happens after we die?” I said, “To be honest, darling—we decompose.” And she wanted to know what that meant. A bird had died in our backyard and so we watched how it disappeared a ...

Now, back to the family cat or dog in labor. By quietly, even sneakily, approaching we observe additional factors involved. 1. The need for darkness and solitude. Bright lights are indeed disturbing. My attempts to take photographs of dogs and cats have been foiled by the indignant laboring mothers retreating to dark secluded place usually physically out of reach of annoying human beings—such as far under the house or barn. 2. The need for quiet becomes obvious. Any loud or unexpected n...

 The Hypocrisy of Elitism

At the same time, children with special abilities and skills need to be nourished and encouraged. They are a national treasure. Challenging programmes for the 'gifted' are sometimes decried as 'elitism'. Why aren't intensive practice sessions for varsity football, baseball and basketball players and interschool competition deemed elitism? After all, only the most gifted athletes participate. There is a self-defeating double-standard at work here, nationwide.
