For quite a while, the U.S. was focused on other parts of the world. Wars in the Middle East, the Greek crisis, and North Korea all made headlines and were front of mind for many investors. Recently, though, that view has largely faded. We are still at war in Afghanistan, but no one seems to be talking about. A hard Brexit is looming, same thing. Attention has returned to what is happening here in the U.S.

I am very pleased to announce that my book, Crash-Test Investing, is finally available for sale on Amazon. Right now, only the paperback version is available, but we are working on the Kindle version. You should buy a copy for every room in your house, all your friends and family, and all the rooms in their houses. Go ahead—I’ll wait! Unless you’re a Commonwealth advisor, in which case you’ll be getting a copy at our National Conference.

Before doing that, however, you might ask yourself these questions: Why do we need another book on investing? And what do I have to offer that made it worth my time to write?

I will be away with my family in Iceland for the next 10 days and will be turning over the blog to my colleagues for that time. We have some very interesting pieces lined up, and I expect you will find them both entertaining and useful. But before I go, here is one last post—a book review!

Yesterday, I wrote about mistakes I’ve made in the past and how I am using that experience to avoid being as wrong—at least in the same way—in the future. So, you can certainly see why a book with “How Not to Be Wrong” as the title appeals to me. The subtitle, “The Power of Mathematical Thinking,” is also attractive, as math is one of the great organizing principles of my profession. On the face of it, this sounds like exactly what anyone in my position should be looking for.

One of the ways I am trying to control my screen-induced ADD is by making myself sit down and read more. It has been surprisingly difficult, as I have apparently largely lost my ability to sit down and concentrate on a book for a period of time. Now that I think of it, this is something that may have been due more to my small son than to screens. In any event, now that he is old enough that we can sit and read together, I am making the effort to relearn concentration.

I don’t read too many books where I find myself repeatedly stopping to underline something while thinking I didn’t know that! There are even fewer that I keep on my shelf in order to reference the list of sources in the back. Connectography: Mapping the Future of Global Civilization, by Parag Khanna, earns both of those distinctions.

It also changed how I look at the world.

Ben Bernanke wrote The Courage to Act to lay out his view, from inside the belly of the beast, of what happened during the 2008 financial crisis. It is worth reading—you will not find a clearer, more informed, and even essentially dispassionate account of the biggest economic crisis in the past several generations. I highly recommend it to anyone who has an interest in understanding not only what happened but why.

One of my particular interests in investing is how to make better decisions. I’ve written before about biases and problems we face, and much of the current research is in fields such as behavioral finance, with a focus on how to avoid mistakes that seem to be hardwired into our brains.

As I’ve noted over the past couple of days, Europe is back in the headlines. The confrontation between Greece and Germany has once again captured the world’s attention with the real prospect that the eurozone could break down.

One of the fundamental principles of economics is “rationality”—the notion that all actors in a market have similar information, preferences, and abilities to project the future.

Like all economists, I know this isn’t really true, yet it still influences how I view the world. So the extent to which Daniel Kahneman proves this idea false—not just at the aggregate level, but at the individual level—comes as something of a shock.
