Future Bright by Martin E. Martinez

Higher intelligence is linked to higher achievement. The demands of our world and culture are calling for higher achievement to address increasingly complex problems. As individuals and societies, we should strive to increase intelligence, which is possible, to arm ourselves to overcome these challenges. This is the opinion advanced by education professor Martin E. Martinez in his book Future Bright.

Martinez builds his case by starting with the link between intelligence and achievement. He cites studies that indicate that in school, work, and personal life, achievement is positively correlated to intelligence.

He moves on to describe what intelligence is, drawing on historic and current theories and research. A significant portion of the book is devoted to defining and understanding intelligence. The prevailing model is hierarchical. A single general intelligence is linked to achievement in all areas. There are also different types of intelligence that are linked to success in clusters of specific skills. Intelligence is affected by both genetics and the environment, and by both individual and cultural factors. If you are looking for a primer on intelligence that covers a lot of ground relatively briefly, you can find it in these chapters.

The hope that Martinez offers is that intelligence is, in part, learned, and it can be increased. Two major types of intelligence, most strongly related to general intelligence, are fluid and crystalline intelligence. Fluid intelligence is related to successfully dealing with novel situations. The heart of fluid intelligence is problem solving.  Crystalline intelligence is structured knowledge, such as is attained from formal education. It is not merely an accumulation of facts; it is an organized mental repository of useful information. The primary skill for crystalline intelligence is critical thinking, the ability distinguish credible, worthy, and useful ideas.

Problems solving and critical thinking are skills that can be learned and improved. Similarly, we can learn new information. By these means fluid and crystalline intelligence, and with them general intelligence, can be increased.

Intelligence is not the only determinant of success, for many intelligent people are not successful. Another important factor is what Martinez call “effective character.” These are personality traits that Martinez suggests can be learned or improved in most people. The critical trait is conscientiousness. Conscientiousness is associated with setting and pursuing goals, working with diligence, and seeking excellence.

Martinez offers several strategies for increasing intelligence. One that is in keeping with the motivation behind this blog is to increase crystalline intelligence (structured knowledge) by reading books. A work as long a book must be structured well to be coherent from beginning to end. In addition, effective written communication presents ideas in a manner that lends itself to analysis by critical thinking. Nonfiction books are especially useful for cultivating crystalline intelligence.

Though the strategies are aimed at the individual, he discusses how some of them are adaptable to parenting and schools. Because Martinez in the early chapters suggests societal benefits to higher intelligence, it makes sense that his book would also include suggestions for policy and cultural adaptions.

The Organized Mind by Daniel J. Levitin

Modern life presents us with too much stuff and too much information to deal with. In The Organized Mind, psychologist Daniel J. Levitin explains how we can work with our mind, instead of against it, to handle information and make better decisions.

Attention is the critical resources for taking in information, making good decisions, and forming memories. The difficulty is that we only have so much attention to go around. Our attentional systems work to make us unconsciously ignore many of the signals that come our way; we would be overwhelmed if they did not. Our built in systems pay attention to change or to things that seem important. Our natural state is to have a wandering mind, broadly attentive to the environment, screening out the stable and safe, occasionally zooming in on something novel or critical.

We can also use the executive functions of our mind to focus attention where we want it. This can consume a lot of energy, but we can do it very effectively, sometimes focusing to the point where we lose track over everything else.

Both forms of attention have their strengths and limitations. In addition, it is costly to our attention bank to switch between modes or to switch focus from one subject to another. The load of information that we have to deal with can exhaust our attentional system, leading to inattention, poor memory, and bad decisions.

Levitin offers solutions to alleviate these problems and work with the strengths of our brains. The primary suggestion is to offload as much information as possible to the environment. The less we have to remember, and the fewer minor decisions we have to make, the better off we’ll be. Highly successful people use systems of habits, calendars, filing, labels, and standards to minimize the amount of information they have to carry in their memories. It is often not so important to know something as it is to be able to find it when you need it.

A related concept is to use categories and chunk up information. Our minds do this naturally. For instance, we typically don’t remember a telephone number as seven digits, but as two chunks of digits. We can apply a chunking strategy by breaking large jobs into doable tasks, or be grouping related tasks together. We can create scenes or stories in our mind (we do it anyway) to connect a string of events. Sleep seems to be important our natural chunking process, consolidating memories, connecting new information to old, and formulating new concepts.

Levitin presents many tools to organize information and things to make it easier on our brains. In my opinion, one of the most helpful tools is the fourfold table. This is a simple method to organize statistical information and assess the probabilities of certain outcomes. We have horrible intuition for understanding probabilities and assessing risks. Even people trained in statistics typically get probabilities wrong when they guess. The fourfold table, which Levitin describes in some detail with examples, allows one to break down the numbers and evaluate the most relevant probabilities.

The Organized Mind is not a how-to manual, though it has many strategies for organizing based on how the brain works. Levitin discusses the structure and function of parts of the brain, but is not excessively technical. A reader could skim these sections without too much loss. A reader could also focus on a particular aspect of organizing (business, time, and even social life) based on the way the book is organized, though the first few chapters have a lot of information that is background for the other sections.

The Big Thirst by Charles Fishman

More than 1 billion people do not have access to clean drinking water.  Australia has suffered a decade-long, continent-wide drought.  Even seemingly water rich places, like Atlanta, Georgia, can’t get enough water.  Many are talking of a global water crisis.  Except, as Charles Fishman aptly states it in The Big Thirst, “There is no global water crisis, there are a thousand water crises, each distinct.”

I think the story of Atlanta and Lake Lanier, as told recounted by Fishman, is especially instructive.  Lake Lanier on the Chatahoochee River is the source of 75 percent of the water used by Atlanta, 5 million gallons a day.  A drought in 2007-2008 brought the level of the lake dangerously low, prompting downstream states to sue over the amount of water Atlanta was taking.  The federal court declared that Atlanta had been illegally receiving water from the lake and had to find another source.  Atlanta has a lot of resources, barely tapped conservation efforts, reuse, and alternative supplies, but with a lack of political will, leadership, and vision, it leaders threw up their hands in impotent defiance of the court and whined they must have Lake Lanier water.  When the lake was built, Atlanta passed on paying for a piece of it thinking it would never be needed, and now they think they can’t live without it.


Part of the point Fishman makes it that water crises are more often than not political crises.  There is a lack of political will and sense of necessity, even though the problems can be plain and the solutions within reach.  The Big Thirst includes examples from around the world (the United States, India, and especially Australia) where people are facing water problems.  Happily, many of them have taken a more realistic and reasonable approach than Atlanta.

Fishman is going for something deeper, though.  Our political and economic stumbling in the area of water management stems for our cultural relationship with water.  It is obviously necessary for life.  We also consider it beautiful, it is part of our landscape, and in some places it has important religious significance.  Even so, we have difficulty understanding the value of water, comparing one use to another, assigning responsibility for its distribution and quality, acknowledging the infrastructure needed to have water when and where it is needed.  It the West, where for the last century we have enjoyed incredible access to abundant water, we hardly ever think about water unless we have some professional connection to it.

We can’t continue to be mindless of water.  The systems of water abundance we built in the last century aren’t sustainable without major ongoing investment.  In light of climate change, they may be altogether unsustainable.  Even without climate change, much of our water policy dates to a time of unusual water abundance.

Fishman encourages water mindfulness.  We need to reconnect to water.  In part, this reconnecting means understanding what it means to have water in our homes and in our streams.  It is also connecting to how critical water is to food, energy, commerce, health, and almost every aspect of life.  Our decisions about water need to be rooted in reality.

Readings from Your Best Life Now by Joel Osteen

Daily Readings from Your Best Life Now, is a daily devotional adapted from Joel Osteen’s breakout bestseller Your Best Life Now. The primary divisions of the book follow that of the source material. Likewise, the body of each short chapters is adapted closely from the original material. However, this book is organized differently. It is divided into 90 chapters, each one kept short in order to fit into a daily reading schedule.

At the top of each chapter is a reference to a passage of scripture. The chapters in the book are not expositions on the scripture; Osteen is plain in the introduction that that was not his intention. Osteen’s books, like his televised sermons, are topical rather than expositional. I thought that the connection between the scripture reading and the chapters were sometimes tenuous.

I’ll admit I took much longer than 90 days to finish this book (I probably first opened it shortly after it was published in 2005). That may have injured my sense of the book as a whole, but I think that the book was written with the hope that each chapter would be able to stand on its own as a sermonette of encouragement.

Encouragement is a good word for the book. It’s the theme through every part from encouragement to dream bigger to encouragement to press on in the hard times.

That leads also to what I think is the weakness of the book, and Osteen’s ouvre in general. It seems to draw from the theme and concepts of self-help as much (or more) as from the Bible. Even in the introduction, Osteen speaks in one sentence of wanting people to draw near to God and in the next of helping readers “unlock the doors of a fuller life.” These are not mutually exclusive pursuits, but that depends a lot on your concept of a fuller life.

I don’t mean to be too critical of Osteen. Obviously, I read several of his books and books by his predecessors as preachers of positivity in popular culture, Robert H. Schuller and Norman Vincent Peale. I have felt encourage by reading the books of these men, but I also leave there books feeling like something much deeper is missing.
