New Think: The Use of Lateral Thinking in the Generation of New Ideas by Edward de Bono

It's 19th century England, and you're the beautiful daughter of a man deeply in debt. The man's moneylender, an old and repulsive man, offers a deal: Let me marry your daughter and I'll forgive all the debt. You'll be spared going to prison, and your daughter won't starve.

The man and his daughter were horrified. To convince them, the moneylender proposed letting fate decide the matter. He told them he would put a black pebble and a white pebble in a bag, and the girl would pick one of the pebbles at random. If she chose the white pebble, the debt would be cancelled and she could stay with her father. If she chose the black pebble, she would become the moneylender's wife and the debt would be cancelled.

Seeing no alternative, they reluctantly agreed. As they were standing on a path strewn with pebbles, the moneylender bent to pick up two to put into the bag.

Unfortunately, the alert girl saw to her horror that he selected two black pebbles to put into the bag.

**************************
If you were this girl, what would you do?

And this is how New Think: The Use of Lateral Thinking in the Generation of New Ideas begins. Author Edward de Bono compares and contrasts what he calls vertical thinking (traditional thought processes which use logic and reasonable assumptions, seen by many as the only form of "respectable" thinking) to what he calls lateral thinking, which involves looking at a subject in unusual, illogical and even irrational ways to arrive at more creative solutions.

If lateral thinking, rather than vertical thinking, is the source of most of the world's brilliant insights and inventions, how can you train yourself to use it to your advantage, especially when it seems this type of thinking often occurs by accident or pure chance? de Bono describes several techniques you can use, such as chance, games, random associations and other approaches, to harvest ideas and achieve greater creativity.

There are some true jewels of insight in this brief 156-page book. Unfortunately, you've got to wade through quite a bit of passive voice and convoluted phrasing to get to them. I wish that this author, who is such a champion of counterintuitive thinking, had just this once reached a more traditional conclusion: that his ideas would find a larger audience if they were better organized and more clearly articulated.

Furthermore, many of these concepts are described much more engagingly in books like Blink and The Black Swan. I'd start with those books first, and if the subject matter truly interests you, then you can move on to New Think.

***************************
Here's the conclusion to the story of the moneylender and the beautiful daughter:

The daughter gritted her teeth, reached into the bag, and pulled out a pebble. But before she opened her hand and looked at it, she casually dropped it on the ground, where it was immediately lost among all the other pebbles on the path.

"Oh, how clumsy of me!" she said. "But never mind--if you look into the bag you will be able to tell which pebble I took by the color of the one that is left."

The banker, unable to protest because it would prove his dishonesty, had no choice but to cancel the debt and let the girl stay with her father.

Reminiscences of a Stock Operator by Edwin Lefevre [fictionalized bio of Jesse Livermore]

"History repeats itself all the time in Wall Street." A fictionalized biography of Jesse Livermore, one of history's most famous speculators. This is an enriching book, worth reading every decade or so across your investment career. And it's a genuinely fun read, conveying the free-wheeling investment culture of the days before the Securities and Exchange Act. When you're young and beginning to invest, this book thrills you with all the bravado of speculating. When you're older, after you've seen a few things and learned many of the manipulations and other techniques the investment industry uses to extract money from you, the book becomes more of a cautionary tale of things not to do, traps not to step in, things to avoid. This is the third time I've read this book (I'm now in my fourth decade as an investor, so I guess that makes me one reading behind schedule), and what struck me most this time around was Livermore's self-admitted weaknesses:...

The Retirement Myth by Craig S. Karpel

A 1995-era book for Boomers by a pre-Boomer (the author is technically a tail-end Silent, but he writes and thinks like a Boomer) who is dismayed at the Boomers' complete unpreparedness as they Boom their way towards an imaginary retirement in a system the author thinks is about to collapse.  Let's get the bottom line out of the way. This is a bad and boring book with incontinent logic.  Then why read it? You  don't have to, and shouldn't. But I often review bad books as an intellectual exercise: to think about what is wrong with a book, what should and should not have been done in writing it, where the errors (of, say, conception, of structure, of logic, of rhetoric) are, and so on. And with books that make predictions, it's a glorious opportunity to practice epistemic humility to read that book after its predictions should have (but didn't) come true. Finally, you can mine even the worst books for useful insights--or in this case contra-insights, since the in...

Confessions of a Medical Heretic by Robert S. Mendelsohn, MD

"I have written this book precisely to scare and to radicalize people before they are hurt. Let this book be your radicalizing experience." The more I come into contact with modern medicine, the more I've watched my elders' lives intersect with it, the more I've observed the field's neomania and accompanying iatrogenic harms, the more I realize that everyone--everyone!--should read the following four books: H. Gilbert Welch: Less Medicine, More Health Ivan Illich: Medical Nemesis Dr. John Sarno: The Divided Mind Robert S. Mendelsohn: Confessions of a Medical Heretic While reading these works, it will be worth noting your internal reaction to them. Do you agree? Do you strongly reject? Why? And what might this indicate about your attachment to your existing beliefs about medicine? In Confession of a Medical Heretic , author Dr. Robert Mendelsohn frames up modern medicine as a type of religion, complete with priests (read: doctors), sacraments, rituals, and even...
