The Senators' Sons Problem

Posted: 30 Nov 2014 09:56 AM PST

Imagine you have to take a test in a room along with 50 other people. I will administer the test, and it will be objective – perhaps just straightforward math problems – and I will grade it anonymously. A very valuable prize goes to each test taker who makes it into the top 5% among the people taking the exam, silently and independently, in the same room with you. You do have a choice, however. You can take the exam in either of two identical rooms, each of which contains the same number of test takers. The only difference between the rooms is the criterion used to select the other test takers. Individuals chosen based on academic merit are in one room. The other room is filled with senators' sons. Against which group would you prefer to compete?


I have noticed that people prefer to compete against the senators' sons. Presumably, privileged though they may be, the senators' sons are easier rivals than a group chosen according to their ability. People seem to feel uncomfortable giving this answer in a public setting, perhaps because someone there might be a senator's son and could take offense (although he may not understand the insult). But keep in mind that we prefer to compete against the senators' sons not because we think that they all are weak performers. Any one senator's son might be quite sharp. Rather, our intuition is that the privileged group is weaker on average than the average of the merit-based group. This is the senators' sons problem: Privilege and merit sometimes are negatively correlated. But why?

Behind the senators sons' problem is a process known as "selection". In most contests, you have to qualify in order to play – as when people try to get into a school or a company, or when firms vie to get into markets or to do business in different countries. Criteria have to be set up to select who gets into these contests and who does not. When merit is the criterion, those who play must be capable. When some other criterion is used, such as privilege (as in the case of senators' sons), then for them being capable is optional. And when merit is optional, average levels of merit will be lower.

In life, both merit and privilege together decide who gets to play. If you lack privilege, you better be good. If you lack merit, but are well connected, then you may be able to play too. In situations like this, merit and privilege are negatively correlated: The senators' sons problem. So if you see someone succeed despite lacking connections, club memberships, and fancy titles, they must be good at what they do. Similarly, if a foreign company excels despite government policies favoring domestic firms, then the foreign firm must be impressive. The same process happens in entrepreneurship, too. Big, established firms rely on their reputation to get business, while start-ups have to prove that they are capable. Consequently, most start-ups fail; those that survive are then especially competitive. In each of these examples, those who make it without privilege had to be good.

I think we all realize that the senators' sons problem is at work in many areas of life, which is why so many people try to deny their own privileged backgrounds. How we all wish we were a "self-made man." People who claim this are really wanting to say "I'm no senator's son." After all, if we got ahead without privilege, then we must be really capable.

So here is the question for you and your organization. How much do you rely on privilege to win in your markets? How much of your performance is based on merit? And, inside your organization, do you reward privilege or merit? In my view, great leaders build companies that win on merit - and inside their firms create systems that reward merit.


For an academic study showing how this idea plays a role in competition, see my paper on compensatory fitness.

"I'd rather be vaguely right than precisely wrong." That's my favorite quote from British economist John Maynard Keynes; it took me a long time to truly appreciate its importance. Math and physics are rooted in equations that spit out precise answers; vagueness there is dangerous — for the right reasons. That is why they are called exact sciences. Investing, despite being taught as an almost exact science, is far from it. It is a craft that falls somewhere between art and science.

A few months ago, while analyzing a company, I asked an executive of a Fortune 500 company what his company's cost of capital was. The answer I got was, "Well, the beta of our stock is 0.6, and our cost of debt is 3.25 percent, so the cost of capital is 6.35 percent." Warren Buffett was asked about Berkshire Hathaway's cost of capital at his recent annual meeting. The Berkshire CEO's answer was vague — "It is what can be produced by our second-best idea" — but it was right.

I am often asked by students if I recommend studying for the Chartered Financial Analyst designation. In the past I always responded with an unequivocal yes. There were many reasons for that: The CFA charter is like getting a master's degree in finance and investing at a fraction of the cost, and it is valued just as much. Employers like it because it is standardized, and they know what you had to learn. The CFA covers a lot of material, from ethics to financial derivatives.

Lately, however, I have found myself qualifying my yes answer. If you are looking to do the CFA for self-education, I wouldn't bother. The reason for that is simple: The CFA curriculum spends too much time on Modern Portfolio Theory (MPT). That is the nonsensical set of formulas used by the Fortune 500 executive to compute his company's cost of capital. (I have to qualify this: I finished my CFA in 2000. Maybe the CFA curriculum has changed since then.)

I've been in the investment industry for almost 20 years. I have had thousands of conversations with other investors about stocks, but I have yet to have one conversation in which beta or Modern Portfolio Theory was mentioned as part of the analytical framework — not even once. You hear MPT and beta in the same sentence with other words such as "useless," "theoretical" and "garbage." If you were to ask what the beta of any company in my portfolio is, I would have no answer for you; I have simply never looked. But ask me about the return on capital or debt of any stock in the portfolio, and I'll be right in the ballpark.

MPT — a Noble Prize–winning theory — has lots of flaws. Beta, a mostly random number, is sitting right in the middle of the calculation of MPT. The theory assumes investors are rational — no, that is not a typo. If you are not laughing, you should be: A recent study by Boston-based research firm Dalbar found that the average (rational) investor in U.S. stock mutual funds received an annual return of 3.7 percent during the past 30 years, significantly underperforming the funds in which they invested (they bought high and sold low), as well as the S&P 500 index, which returned 11.1 percent a year during that period. MPT defines risk as volatility, whereas rational people would say that permanent loss of capital is the real risk.

These are not all the flaws, but it would take too much time to go through them. The central flaw of MPT, though, is that it's a theory with few practical implications. This analytical portfolio framework is used not by analysts or portfolio managers but only by academics and an army of consultants (neither group invests for a living). In other words, by studying MPT your brain cells have died for nothing.

Imagine you are living in the 16th century. Nicolaus Copernicus has already more or less proved that the world is round, but the new textbooks have not yet come out, and the world-is-a-ball theory is not being widely taught. So teachers, who rarely step outside the walls of their own institutions, confidently declare to their students that the world is flat, whereas those who meanwhile roam this wonderful planet more widely (let's call them entrepreneurs and investors) know perfectly well that it is round. This is pretty much what is happening today with the divide between real-world and academic investment professionals.

If you learn anything by going to the Berkshire Hathaway annual meeting, it is the incredible power of incentives. Berkshire vice chairman Charlie Munger is big on that idea. Teachers will teach what is teachable; they'll default to solving a mathematical equation (while stuffing it with arbitrary numbers for the most part), because that is what they know how to do. They can learn MPT by reading their predecessors' textbooks, and therefore that is what they'll teach, too. The beauty of MPT, at least from a teaching perspective, is that it turns investing into a math problem, with elegant equations that always spit out precise, albeit random numbers.

But please don't tell anyone I said this, because as an investor I'd love for MPT to be taught starting in kindergarten. It would make my job easier: I'd be competing against imbeciles who still believe the world is flat. However, as a well-wishing person dispensing advice, I'd say, spend as little time as you can studying MPT.

P.S. Today I wanted to share with you a composition from "Side by Side" a 1994 recording of Oscar Peterson (piano) playing together with one and only Itzhak Perlman (violin) (listen to it here). I think owned this CD recording for twenty years (for all young fellows out there reading this, it is a great CD to impress girls, a side from the fact that it is wonderful music). While looking for this piece I stumbled on a wonderful concert recorded in 1980 – Oscar Peterson (piano), Joe Pass (guitar), and Count Basie (piano). (listen to it here).
