Improving Your Memory (Essential Managers) by David Thomas

I know the book author and have heard him speak on this topic several times.  The book contains the key elements of his presentations but you really should hear him in person if you get the chance.


Memory-training techniques will certainly improve your IQ – by broadening your vocabulary, for example. Another way to increase your score is to practise doing the test: each time you do an IQ test, you learn from the questions asked, so your memory builds up a bank of experience that it can call upon in the future.Read more at location 99
Also fundamental to memory training is the brain’s natural propensity to organize information in patterns. Look for patterns and, if order is not paramount, reorganize the information. For example, when you have a list, look for words beginning with the same letter. See if things fit into categories: perhaps five things are items of stationery and four are household objects. Are any of the things the same colour? By breaking a large group of things into several smaller ones, you make it easier to assimilate.Read more at location 355

Most new information is lost within one day if you do not go over it an hour after learning it. Only by reviewing at regular intervals will you maintain long-term recall. As you become proficient at memorizing and recalling, you will feel confident enough to set new targets.Read more at location 1047

Mistakes were Made (but not by me) by Carol Tavris, Elliot Aronson


Similar to some of the material in the Psychopath Test I read in November in a strange way, this book looks at our in-built tendency to judge others by different standards than those we use on ourselves.
How our memory is not what it seems at all, how it reconstructs the past so it fits with our view of the world and of ourselves.
How the well meaning social services teams construct abuse that never happened.  How judges and prosecutors cannot accept that innocent men were imprisoned (or given the death penalty)

Perhaps my favourite quote is the last in this blog from a Chinese philosopher more than 2500 years ago - we really haven't come that far since then!

“There is probably no such thing as a conscious hypocrite.” It seems unlikely that Newt Gingrich said to himself, “My, what a hypocrite I am. There I was, all riled up about Bill Clinton’s sexual affair, while I was having an extramarital affair of my own right here in town.” Similarly, the prominent evangelist Ted Haggard seemed oblivious to the hypocrisy of publicly fulminating against homosexuality while enjoying his own sexual relationship with a male prostitute.Read more at location 174

So powerful is the need for consonance that when people are forced to look at disconfirming evidence, they will find a way to criticize, distort, or dismiss it so that they can maintain or even strengthen their existing belief. This mental contortion is called the “confirmation bias.”Read more at location 384
see.” Self-justification, therefore, is not only about protecting high self-esteem; it’s also about protecting low self-esteem if that is how a person sees himself.Read more at location 612
people will bend over backward to reduce dissonance in a way that is favorable to them and their team. The specific ways vary, but our efforts at self-justification are all designed to serve our need to feel good about what we have done, what we believe, and who we are.Read more at location 726
Just as we can identify hypocrisy in everyone but ourselves, just as it’s obvious that others can be influenced by money but not ourselves, so we can see prejudices in everyone else but ourselves. Thanks to our ego-preserving blind spots, we cannot possibly have a prejudice, which is an irrational or mean-spirited feeling about all members of another group. Because we are not irrational or mean spirited, any negative feelings we have about another group are justified; our dislikes are rational and well founded. It’s theirs we need to suppress.Read more at location 998
Once people have a prejudice, just as once they have a political ideology, they do not easily drop it, even if the evidence indisputably contradicts a core justification for it. Rather, they come up with another justification to preserve their belief or course of action.Read more at location 1073

Fortunately, we can also better understand the conditions under which prejudices diminish: when the economic competition subsides, when the truce is signed, when the profession is integrated, when they become more familiar and comfortable, when we are in a position to realize that they aren’t so different from us.Read more at location 1142
We need a few trusted naysayers in our lives, critics who are willing to puncture our protective bubble of self-justifications and yank us back to reality if we veer too far off. This is especially important for people in positions of power.Read more at location 1152

Many judges, jurors, and police officers prefer certainties to science. Law professor D. Michael Risinger and attorney Jeffrey L.

in the way each side tells the same story. Perpetrators, whether individuals or nations, write versions of history in which their behavior was justified and provoked by the other side; their behavior was sensible and meaningful; if they made mistakes or went too far, at least everything turned out for the best in the long run; and it’s all in the past now anyway. Victims tend to write accounts of the same history in which they describe the perpetrator’s actions as arbitrary and meaningless, or else intentionally malicious and brutal; in which their own retaliation was impeccably appropriate and morally justified; and in which nothing turned out for the best. In fact, everything turned out for the worst, and we are still irritated about it.Read more at location 3248
The implications of these studies are ominous: Combine perpetrators who have high self-esteem and victims who are helpless, and you have a recipe for the escalation of brutality.

The moral of our story is easy to say, and difficult to execute. When you screw up, try saying this: “I made a mistake. I need to understand what went wrong. I don’t want to make the same mistake again.” Dweck’s research is heartening because it suggests that at all ages, people can learn to see mistakes not as terrible personal failings to be denied or justified, but as inevitable aspects of life that help us grow, and grow up.Read more at location 3855
As the Chinese philosopher Lao Tzu (“Old Master”) observed more than twenty-five-hundred years ago: A great nation is like a great man: When he makes a mistake, he realizes it. Having realized it, he admits it. Having admitted it, he corrects it. He considers those who point out his faults as his most benevolent teachers.Read more at location 3882

The Social Animal: A Story of How Success Happens by David Brooks


A very interesting approach to writing a book that looks at what are the secrets for a happy and successful life - it follows teh story of two individuals from birth through to death and how they come from very different backgrounds, eventually marry and spend a life together.  The story itself is not a completely happy one (I won't spoil the ending) but it really makes you think about how much we can really mould future generations, given where individuals start from.

It reviews teh evidence about what can (and what cannot) make a difference to peoples lives.


And over the past generations we have seen big policies yield disappointing results. Since 1983 we’ve reformed the education system again and again, yet more than a quarter of high-school students drop out, even though all rational incentives tell them not to. We’ve tried to close the gap between white and black achievement, but have failed. We’ve spent a generation enrolling more young people in college without understanding why so many don’t graduate.Read more at location 127 •
Janine Willis and Alexander Todorov of Princeton have found that people can make snap judgments about a person’s trustworthiness, competence, aggressiveness and likability within the first tenth of a second. These sorts of first glimpses are astonishingly accurate in predicting how people will feel about each other months later. People rarely revise their first impression, they just become more confident that they are right. In other research, Todorov gave his subjects microsecond glimpses of the faces of competing politicians. His research subjects could predict, with 70 percent accuracy, who would win the election between the two candidates.Read more at location 284 •
As Geoffrey Miller notes in The Mating Mind, people tend to choose spouses of similar intelligence, and the easiest way to measure someone else’s intelligence is through their vocabulary. People with an 80 IQ will know words such as “fabric,” “enormous,” and “conceal” but not words such as “sentence,” “consume,” and “commerce.” People with 90 IQs will know the latter three words, but probably not “designate,” “ponder,” or “reluctant.” So people who are getting to know each other subconsciously measure to see if their vocabularies mesh, and they adapt to the other person’s level.Read more at location 327 •

The truth is, starting even before we are born, we inherit a great river of knowledge, a great flow of patterns coming from many ages and many sources. The information that comes from deep in the evolutionary past, we call genetics. The information revealed thousands of years ago, we call religion. The information passed along from hundreds of years ago, we call culture. The information passed along from decades ago, we call family, and the information offered years, months, days, or hours ago, we call education and advice. But it is all information, and it all flows from the dead through us and to the unborn.Read more at location 647 •
This activity of blending neural patterns is called imagination. It seems easy but it is phenomenally complex.

If there is one thing developmental psychologists have learned over the years, it is that parents don’t have to be brilliant psychologists to succeed. They don’t have to be supremely gifted teachers. Most of the stuff parents do with flashcards and special drills and tutorials to hone their kids into perfect achievement machines don’t have any effect at all. Instead, parents just have to be good enough. They have to provide their kids with stable and predictable rhythms. They need to be able to fall in tune with their kids’ needs, combining warmth and discipline. They need to establish the secure emotional bonds that kids can fall back upon in the face of stress. They need to be there to provide living examples of how to cope with the problems of the world so that their children can develop unconscious models in their heads.Read more at location 1097 •

The people in the executive suites believed that the school existed to fulfill some socially productive process of information transmission—usually involving science projects on poster boards. But in reality, of course, high school is a machine for social sorting.

Of course, Ms. Taylor wanted to impart knowledge, the sort of stuff that shows up on tests. But within weeks, students forget 90 percent of the knowledge they learn in class anyway. The only point of being a teacher is to do more than impart facts; it’s to shape the way students perceive the world, to help a student absorb the rules of a discipline. The teachers who do that get remembered.Read more at location 1438 •

Incognito, the secret lives of the brain by David Eagleman


A very readable book outlining the advances in understanding mind and brains.  The essence is that the conscious part (the part we call me) is actually a very thin layer on top of our existence.  Almost all of what we do is unconscious, our conscious sense of self just rationalises what we have just done to make sense of it for future occasions.  The only time we really use our conscious self is when setting goal sor long-term plans, but even then we are driven by our unconscious experience and desires.

The fact that what we think we preceive, is actually a construction of our brains and is quite often not so strongly connected with pyhsical external reality.  The book does have some philosophical implications for freewill, mentions them but doesn't really answer the problems it raises.

The first thing we learn from studying our own circuitry is a simple lesson: most of what we do and think and feel is not under our conscious control.Read more at location 84 •

From the natural laboratory of evolution comes a related phenomenon in humans. At least 15 percent of human females possess a genetic mutation that gives them an extra (fourth) type of color photoreceptor—and this allows them to discriminate between colors that look identical to the majority of us with a mere three types of color photoreceptors.36 Two color swatches that look identical to the majority of people would be clearly distinguishable to these ladies. (No one has yet determined what percentage of fashion arguments is caused by this mutation.)Read more at location 692 •
The bottom line is that time is a mental construction, not an accurate barometer of what’s happening “out there.” Here’s a way to prove to yourself that something strange is going on with time: look at your own eyes in a mirror and move your point of focus back and forth so that you’re looking at your right eye, then at your left eye, and back again. Your eyes take tens of milliseconds to move from one position to the other, but—here’s the mystery—you never see them move. What happens to the gaps in time while your eyes are moving? Why doesn’t your brain care about the small absences of visual input?Read more at location 829 •
consciousness tends to interfere with most tasks (remember the unhappy centipede in the ditch)—but it can be helpful when setting goals and training the robot.

The chicken/shovel experiment led Gazzaniga and LeDoux to conclude that the left hemisphere acts as an “interpreter,” watching the actions and behaviors of the body and assigning a coherent narrative to these events. And the left hemisphere works this way even in normal, intact brains. Hidden programs drive actions, and the left hemisphere makes justifications. This idea of retrospective storytelling suggests that we come to know our own attitudes and emotions, at least partially, by inferring them from observations of our own behavior.Read more at location 2166 •
Minds seek patterns.

Human programmers approach a problem by assuming there’s a best way to solve it, or that there’s a way it should be solved by the robot.
