I get a lot of emails wondering what books I read, so I decided to make a list of them.
Here are 50 of my favorite books in personal finance, social psychology, entrepreneurship, and design. Each one has been pretty influential to me. Check them out.
Note: This damn Amazon thing was the easiest way out there, but it still doesn’t work perfectly. If the box below doesn’t show up properly, here’s a full link: http://astore.amazon.com/iwillteachyou-20.

I’m thrilled to announce that I’ve signed a book deal with Workman Publishing for the I Will Teach You To Be Rich book.
Yes! First, I have to say thanks to everyone who reads iwillteachyoutoberich. Every time I get a comment or an email, I hope you know how happy I am. It’s the reason I plaster my email address everywhere.
My agent, Lisa DiMona of Lark Productions, is the most positive person I’ve ever worked with–and she can close deals. Thanks, Lisa! I also look forward to working with Susan Bolotin, my editor at Workman, to make this book something you’ll love. And yes–there will be lots of new stuff.
Finally, thanks to my parents, who always told me, “Why don’t you write that up? How about submitting it to the newspaper? What’s the worst that could happen?”
More details to come later. But for now, thanks!!

I have an odd goal today. By the end of this post, I hope you’ll have a healthy distaste for financial “experts” and magazines, Wall Street’s hype, and the random people you hear pontificating about what the market will do next week. Basically, I hope you start scoffing at everyone after today.
But first, a little background. Today, I’m reviewing chapter 13 of The Bogleheads’ Guide to Investing, one of the most excellent books on investing anywhere. If you’re looking for a book to get started investing, I recommend this one–it has no hype, just sensible advice for long-term investing, based on John Bogle’s ideas (he founded the Vanguard Group).

Also, here’s an interesting twist: Each chapter is being reviewed by a different blogger, so you can get to know some of the other bloggers in the personal-finance community. Check out the full list here.
Chapter 13 is called Performance Chasing and Market Timing, so let’s get to it.
Everyone’s got an opinion, and when it comes to investments, it seems the louder someone shouts or the bigger font a magazine uses, the more attention it gets. Too bad iwillteachyoutoberich readers are too smart to get swayed by this idiotic hype. I’ve said it before and I’ll say it again: There’s a difference between being sexy and being rich.
That’s why when I’m reading some blog’s comments and I see people absolutely sure about which direction interest rates are going, or whether we’re in a bubble, or how likely P/E ratios are to stabilize to pre-2000 levels, I just ignore them (or mock them). We love to talk. But that doesn’t make us right.
So today, before we get to some actual data, I thought I’d ask when the last time you saw one of these things happen was:
If so, then you know the odd confidence that comes along with these predictions. Unfortunately, most people–experts included–are usually wrong.
Why We Can’t Time The Market
We’re really bad at predicting what’s going to happen next. The chapter goes into great detail about market timing, or trying to guess what the market will do, so I’ll just summarize some of the key points here. We’ve talked about hindsight bias, a psychological phenomenon in which things seem clearer in retrospect and we think we knew it all along. This applies to personal finance, too. As the Bogleheads authors write, they launched a contest in 2002 to predict the closing price of the Wilshire 5000 Index (it’s kind of like the S&P 500). The contest included “177 predictions [and] the forecasts of 11 major Wall Street brokerage firms. Here’s what happened:
Stunning. And that was just the direction of the market. It turns out we also chase performance, meaning we buy when things are high and sell when they’re low.
Unfortunately, we often use heuristics to make our own decisions about which funds to invest in, decisions which are usually biased. Take the Janus “Ratings & Rankings page,” which lists impressive rankings for their many funds. Wow! I better invest right now!
Not so fast. There’s a little thing called survivorship bias, which is “the tendency for failed companies to be excluded for performance studies due to the fact that they no longer exist.” This can profoundly affect the performance rates you read about in financial magazines. An analogy helped me understand when I first learned about survivorship bias, and fortunately someone named Patri Friedman has written about it (using examples of poker and mutual funds). “There is a particularly clever scam,” he writes:
Get a list of email addresses of people interested in sports betting. Say you have 32,000. Email 16,000 of them to say that the home team will win this week’s big team, and 16,000 to say the home team will lose. Now, half of the people will have gotten the correct prediction, and the next week, you do the same thing with them. After 5 weeks, you’ll have 1,000 email addresses of people who have seen you pick the winner five times in a row!. Now you pitch your 1-900 number or paid email list subscription to this amazed group.
Are The Financial Experts Right?
This part of the chapter was my favorite. It shows just how much faith we put in financial “experts” who actually aren’t very good at predicting the future (it’s really hard), are subject to hugely distorting cognitive biases, and are rarely held accountable for their calls. Some examples from the book:
Further Thoughts
This chapter isn’t perfect. I know of many more persuasive stories on market timing that could have gone into the book, but the authors didn’t include it. Also, even though the book was published in 2006, it’s impossible to keep up with the current news online. That’s why stories like this one, about code-breaking contest in which a group of three women who beat engineering and cryptanalysis experts from places like the NSA, couldn’t make it. If it were up to me, I would have included a recent New Yorker article on experts (one of the best I’ve ever read), and another from researcher Susan Blackmore. These disparate articles help to poke holes in our theories about experts and point out, quite convincingly, that just because someone’s an expert doesn’t mean he’s right. In fact, it’s often quite the contrary.
Still, I love this chapter and I love this book. You won’t find a size 81-font headline screaming at you about THIS YEAR’S BIGGEST OPPORTUNITIES!!! You won’t find some sexy angle on investing. You will find a sensible way to invest–one that, unfortunately, won’t seem very extraordinary to your friends. But frankly, once I’m educated about risks, investing, and the research, I don’t give a damn what other people think when I’m working towards my financial goals. By the way, the chapter had a lot of points about people not being very smart predicting what’s next.
That’s partially true and partially not. We’re not very good at predicting short-term results, which I’ve always said. But we can set up diversified systems (like index funds in different sectors, for example) that mitigate our lack of predictive power and actually work to get us superior returns. Even after you read this chapter, you’ll see that it’s not all doom and gloom about investing. There are ways to make significant amounts of money. They just don’t involve chasing the best-performing fund or investing in the stock du jour. With this book (and a few other good ones), you can use actual, real data to see what results in the best return. Instead of just being a blowhard who talks loudly about globalization this, and real-estate bubble that, you can look for trends that help you understand what’s going on–and, yes, what to do next.
Special note: JLP from AllFinancialMatters was happy enough to coordinate the publishers sending me a review copy of this book, which I’m giving away to a random commenter on this post. (I already had a copy before they sent this to me.)
What now?

It’s about $16 and, if you apply what you learn, it could make you thousands of times that money back.
