The Robert Day School is hurting CMC’s leadership efforts

Note: I wrote this last year a few days after I was rejected from the Robert Day Scholars Program. This year’s Scholars were just announced, and I thought it was worth reposting.

Let’s say you had $360,000 to give away every year to undergraduates and you wanted to encourage future leaders, or increase the net amount of business success enjoyed by undergraduates at your school. What would be the best way to spend the money?

Observation #1: It’s difficult to predict who is going to be successful and who isn’t. Arguably, 2 of the top 3 earners that CMC has produced were C students when they were here. Robin Williams went to CMC and dropped out; so did Ben Casnocha. I have heard that Robert Day himself, and Henry Kravis, were C students; George Roberts would bet on horses at Santa Anita every day after class. Clearly, the Robert Day program wants to maximize the number of future Kravises and Robert Days, but Kravis and Day probably would not have had the grades to get into the program.

We can observe which students have taken leadership roles, and which students have high status, and we can give a work sample assessment, but these are merely rough indicators – the work sample assessment has only a 0.52 correlation with future job success.

One crucial factor is luck; people have to be at the right place at the right time, and it’s hard to predict which fields are going to be huge, or which person will start the right company or strike up the right conversation at a bar, or join the right startup. Maybe we can assign a percentage chance of wild success to every student, but I would guess that the difference between students in the top GPA decile and students in the bottom GPA decile is maybe 0.4.

Observation #2: If you want students to succeed, instead of telling students they are smart, tell them they are not working hard enough. There’s a reason successful coaches don’t tell their players, “You guys are so athletic and so good. You deserve your #1 ranking and you are all surefire lottery picks. Let me buy you some pizza.” Complacency is not a good leadership trait, and successful students/athletes hear “You’re so smart” more than enough as it is. It’s not clear that, even if you could identify successful students, that giving them a large chunk of cash is ideal, if it could make them complacent. While we give scholarship money to athletes, this is largely a prize so that they want to choose our program, and we take it away if they are unmotivated, or unsuccessful.

Indeed, the students who are rejected from the cash/status giveaway program might develop a chip on their shoulder and become more motivated than the students accepted to the program. I am reminded of Michael Jordan, who was cut from his high school JV team, or CMC trustee Augie Nieto, who was told by his thesis adviser that his plan to develop a series of exercise machines would not work, and he went on to turn the thesis into the multimillion dollar LifeFitness company. There is a selection bias at play here, but it would be good to study if the Robert Day program had a measurable effect, and if so, what that effect was.

Observation #3: Leadership skills, as well as skill at becoming exceptional, can be taught. Some high status students are natural leaders and others have the decision-making skills to become leaders but maybe not the body language, or ability to inspire others. Where should we focus our attention: on making the potential stars into superstars or on sharpening the diamonds in the rough? Given the luck-based nature of success, I would be tempted to focus at the margin but it depends on your estimates of the your ability to make a difference, as well as the goal of your program.

Recommendation: The key is to design your program to send different messages to different groups. To the group of super-bright, super-driven, super-body language, super-ability to inspire students, you want to send a message that says, Don’t get complacent, no one’s looking out for you, if you want to get anywhere you need to work harder. These students are probably going to out-earn their peers, and everyone knows it; if you gave this group money, you would probably get the least bang for your buck, as well as cause resentment among other students and professors.

To the group of marginal students, who maybe aren’t as driven as the top group, you want to send an encouraging message, and spend more attention, in the hopes of boosting their leadership skills and giving them confidence and a better chance of success in the workplace. In theory, you could achieve this by setting up a status and cash-conferring scholarship for a select group of students and then deliberately choosing the candidates you think are second-best.

Either way, you’re not touching the C students who might turn out to be brilliant, or lucky, businessmen. I’d probably want to arrange lectures for everyone on how they can increase their impressiveness, and on the importance of body language. I would purchase cameras for every teacher and instruct them to film students any time they present something, and also randomly during class discussion, and then give the tape to students so that they can see the effects themselves. Given that the group who will attend lectures will self-select to be the group that needs it least, I’d want to consistently emphasize the importance of these qualities, maybe give out a cash prize for attendance or include them in the core curriculum.

Conclusion: If I’m in a position to have $360,000 to give away every year, I’m probably interested in showing that I care about future leaders by giving away money, and less interested in actually increasing the number or success of future leaders, e.g. how the program is designed. At the margin, of course.

If I’m so negative about the effects of the Robert Day School on the student body, then why would I bother to apply? It’s usually easier to change organizations from within, and given that the opportunity exists, it would be silly to turn it down. I would like to see more CMC students become future leaders, as they are my peers, and it will make me feel prouder to affiliate with CMC. That said, being a rejected applicant, it will be difficult to suggest and implement any changes to the program, as most of my suggestions will be taken as sour grapes.

  • Cambridge reports that 10-year returns fell from a miserable -4.2% to a downright horrid -4.64% over the relevant period. Five-year returns fell from 4.3% to 4.25%.
  • we exploit variation in the living conditions experienced by Yemenite children after being airlifted to Israel in 1949. We find that children who were placed in a more modern environment (i.e. with better sanitary and infrastructure conditions) were more likely to obtain higher education, marry at an older age, have fewer children, and work at age 55. They were also more likely to be assimilated into Israeli society, to be less religious, and have more worldly tastes in music and food. However, these effects are found mainly for women, and not for men. We also find an effect on the next generation – children who lived in a better environment grew up to have children with more education.

Watson and Jeopardy

My roommates and I usually catch Jeopardy at least once a week, so we were of course excited to watch Watson, the IBM machine, take on Ken Jennings and Brad Rutter in Jeopardy. So far, Watson's done extremely well, getting 13 straight answers right last night, and finishing way ahead of the competition at the end of the game yesterday. In particular I was intrigued by a few things:
  • In case you haven't watched football with me, I generally annoy everyone else in the room the entire game by urging the team with the ball to be more aggressive: pass more, go for it on 4th down, and stop kicking field goals. The data backs me up. Similarly when I watch Jeopardy, I get upset when players land on the Daily Double - the one chance they have to win a ton of money very quickly - and bet very conservatively, throwing away their chance to leave their competition in the dust. So I was intrigued by this comment from Ken Jennings on Watson's performance:
    Daily Doubles aren't distributed randomly...basically, it had thousands of old Jeopardy games in its head and knew where to look. And got very lucky. Most players go top-down, but some hunt for Daily Doubles like Watson. Brad Rutter calls this an arms race: if one player does it, you have to join in to keep up.
    Clearly Watson, as a computer that can compute expected value and forecast his expected winning percentage, has figured out that the Daily Doubles are valuable - he routinely picks questions in the $800 and $1000 row to start the game, and bets big - $6000 at one point - on the question. This play is forcing the other players in the game to improve their strategies. Hopefully this trend will extend to normal games of Jeopardy, as it increases the variance and makes the game more fun to watch. However, Jeopardy's normally a one-off game so it's possible player strategy won't improve.
  • Lots of people make the mistake of assuming a person is "smart" because they are good at Jeopardy. I don't think Jeopardy is a very good measure of intelligence; it measures your knowledge of obscure trivia, as well as your ability to recall it, but there's more to intelligence than an encyclopedia. It's possible this skill is correlated with intelligence (maybe intelligent people read widely, or have better recall), but Jeopardy skill doesn't prove intelligence per se. It's good to see people realizing Watson knows a lot but isn't "smart" - it can't recognize when another contestant gave the same answer, for example.
  • Watson's buzzer pressing mechanism is lightning fast, so it wins the buzzer on every question where it computes the answer by the time Trebek finishes reading the question. I thought this was unfair, but then realized putting an artificial damper on Watson's reaction time would be stupid - if it's a better Jeopardy player under the current rules, then great, and if it's unfair, they should change the rules so everyone gets an equal shot at the question, or use some other mechanism to award first crack at an answer.
