Dubai offers a gram of gold for every kilo of weight lost

AU YEAH: GOLDEN NUDGE

au

One of our colleagues at London Business School was speaking to a doctor from Dubai about the growing obesity problem in the UAE. The doctor felt his patients had a hard time noticing they were gaining weight because their long, loose-fitting traditional garments don’t give much feedback when weight is gained. No tightening waistline to clue you in.

Whatever the cause, there seems to be a weight problem in Dubai and now the government has come up with a clever incentive: lose a kilogram of weight, get a gram of gold.

That’s about 20 bucks a pound (at current rates, for you American readers (13 quid for you Brits)), but what we like best about this nudge is that they’re not giving people 20 bucks. They’re giving gold, which is likely generating much more buzz.

A BEHAVIORAL INSIGHTS TEAM FOR THE STATES

whstp

We’ve posted before about the UK’s Behavioural Insights Team. Some recent good news is that a similar team has been approved for the United States government. What’s more: they’re hiring! The team is led by the impressive Maya U. Shankar, Senior Policy Advisor , who is a Ph.D. psychologist and Rhodes Scholar. We just chatted with Maya and feel that this team is poised to do great things.

With out further ado, the call:

Research to Results:
Strengthening Federal Capacity for Behavioral Insights

Overview:

A growing body of evidence suggests that insights from the social and behavioral sciences can be used to help design public policies that work better, cost less, and help people to achieve their goals. The practice of using behavioral insights to inform policy has seen success overseas. In 2010, UK Prime Minister David Cameron commissioned the Behavioural Insights Team (BIT, https://www.gov.uk/government/organisations/behavioural-insights-team), which through a process of rapid, iterative experimentation (“Test, Learn, Adapt”), has successfully identified and tested interventions that will further advance priorities of the British government, while saving the government at least £1 billion within the next five years (see previous Annual Reports 2010-11 and 2011-12). The federal government is currently creating a new team that will help build federal capacity to experiment with these approaches, and to scale behavioral interventions that have been rigorously evaluated, using, where possible, randomized controlled trials. The team will be staffed by 4-5 experts in behavioral science and experimental design and evaluation. It is likely that selected individuals will serve on a temporary detail under the Intergovernmental Personnel Act before returning to their home organization, which can be a university, non-profit, or state and local government. Our preference is for individuals who are willing to serve full time but we will also consider people who are only in a position to serve part-time. Moreover, several agencies are looking to recruit expert academics to sit directly within their agencies and to help inspire, design, and execute on specific policy projects, and so it is possible to serve in this capacity as well.

If you are aware of individuals with strong analytic skills, experience designing, testing, and evaluating rigorous randomized control trials, and a strong research background in fields such as social psychology, cognitive psychology, or behavioral economics, please encourage them send a CV and contact information to mshankar2@ostp.eop.gov, which will be sent to the relevant parties for consideration.

Job Responsibilities for Central Team:

* Build Capacity: Work with a broad range of federal agencies to identify new program areas that could benefit from the application of behavioral insights. Help to design, implement, and test the relevant interventions using rigorous experimental methods.

* Enhance Capacity: Provide conceptual and technical support to agencies with specific behavioral insights efforts already underway.

* Convene: Lead a multi-agency “community of practice” to identify and share promising practices and common challenges.

* Create and Provide Resources: Generate tutorials and other “how to” documents to help accelerate these efforts within agencies. Manage online library of relevant documents and media.

* Help inspire new ideas: Work with external partners to identify research findings that can inform policy and practice.

We are already working with over a dozen federal departments and agencies on newly-designed behavioral insights projects, including the Department of Labor, Department of Health and Human Services, Department of Education, Veterans Administration, Department of Treasury, Social Security Administration, Department of Housing and Urban Development, and the United States Department of Agriculture.

Below are some examples of U.S. and international policy initiatives that have benefited from the implementation of behavioral insights:

* Increasing college enrollment and retention: Providing streamlined personal assistance on the FAFSA form (e.g., pre-populating forms using tax return data and following up with a personal call) to low or moderate income individuals resulted in a 29% greater likelihood of their attending college for two consecutive years.

* Getting people back to work: Asking unemployed individuals to create a concrete plan for immediate implementation regarding how, when, and where they would pursue reemployment efforts led to a 15-20% decrease in their likelihood of claiming unemployment benefits just 13 weeks later.

* Improving academic performance: Students taught to view their intelligence as a “muscle” that can grow with hard work and perseverance (as compared to a “fixed trait”, such as eye-color) experienced academic boosts of a letter grade, with the largest effects often seen for low-performing students, students of color, or females in STEM-related courses.

* Increasing retirement savings: The Save More Tomorrow program 1) invites employees to pledge now to increase their savings rate later, since self-control is easier to exert for future events; 2) links planned increases in the savings rate to pay raises, in order to diminish loss aversion; and 3) leverages the power of inertia by keeping members enrolled until they reach a preset limit or elect to opt. Adoption of these auto-escalation plans has boosted annual savings by an estimated $7.4 billion.

* Increasing adoption of energy efficient measures: Offering an attic-clearance service (at full cost) to people led to a five-fold increase in their subsequent adoption of attic-insulation. Interestingly, providing additional government subsidies on attic insulation services had no such effect.

* Increasing tax compliance: Sending letters to late taxpayers that indicated a social norm –i.e., that “9 out of 10 people in Britain paid their taxes on time” – resulted in a 15 percentage point increase in response rates over a three-month period, rolling out to £30 million of extra annual revenue.

Numbers worth knowing: 142857

Filed in Encyclopedia ,Ideas
Subscribe to Decision Science News by Email (one email per week, easy unsubscribe)

ONE CRAZY NUMBER

enne

We at DSN thought it would be worth memorizing some reciprocals because we have a system for remembering numbers and because it might come in handy. So, we started writing out 1/x

1/2 = .5
1/3 = .3
1/4 = .25
1/5 = .2
1/6 = .16
1/7 = .142857
1/8 = .125
1/9 = .1
1/10 = .1

Everything seems plain, predictable, ordinary, but what’s that going on at 1/7? .142857 repeating. That’s weird. Everywhere else it’s the first or second digit right of the decimal that repeats, but then at 1/7 you get 6 unique numbers that repeat as a weird group.

Are the multiples of this number weird? They’re even weirder.

1/7 = .142857
2/7 = .285714
3/7 = .428571
4/7 = .571428
5/7 = .714285
6/7 = .857142
See what’s going on there? They’re all just rotations of the same digits, 142857. Just pop digits off the left and stick them on the right to get any of the above.

Or as this blog shows it:

14

If we keep going, we run across
22/7 = 3.142857, which is of course, very nearly (within .0013 of) pi. Weird.

100/7 = 14.2857142857, which is handy b/c it comes up a lot.

Now, we were hooked. A bit of search engine magic showed us that 142857 is kind of famous. It has its own Wikipedia page.

And it has other kooky propreties:
142+857=999 and
.142+.857 = 1

What’s more, 142857 is a Harshad number, which means it is divisible by the sum of its digits:
142857/(1+4+2+8+5+7) = 5291

What’s surely not the last oddity, if you write the numbers 1 … 9 around a circle, put a triangle connecting 3, 6, and 9 and then connect 1, 4, 2, 8, 5 and 7, you get the New-Agey enneagram pictured above.

Which airline should you be loyal to?

LOYALTY PROGRAM CHOICE BASED ON DEPARTURE COUNT

flights.alldest.sm.frompdf

If you read Decision Science News, you’re probably a professor or grad student or researcher or policy type who flies around a lot to conferences, symposia, workshops, tutorials, summer schools, and all-hands meetings. You travel the globe to give talks and work with co-authors. All this flying around is hard on you, but, you find it gets easier on you when you have status on the airlines you use through their frequent flier programs. Status allows you to choose your seat easily (which helps if you are tall), board early (which makes it easier to carry on luggage, which saves time), upgrade to business class (which helps you get work done), etc. You have found that being loyal to one airline pays off in terms of status.

But which airline should you choose to be loyal to? A simple rule would be to choose the airline that has the most departures from your home airport.

We figured this out for where we’re based: New York City. We scraped all the flights departing from NYC’s three airports (LGA=LaGuardia, JFK=John F Kennedy, EWR=Newark) for an entire week and looked at which airlines had the most departures. This was disappointing because a huge number of the flights listed were by regional airlines you never heard of like “ExpressJet” and “Chautauqua Airlines”(*). Codeshares. So, we scraped the web to figure out who these little airlines were actually flying for, the Deltas, Americans and Uniteds of the world.

The result is above. In short:

  • If you live in NJ, go with United
  • If you’re a LaGuardia/JFK flyer, go with Delta

This surprised us. We thought American had the most out of the New York airports. Once again, a little data analysis provides big insight.

What do you do if you discover you want to switch loyalties? We’ve heard (but not tried it) that you can get status on one airline with proof of status on another airline. We hear you need to fly a certain amount in 6 months or they revoke it.

Now, suppose you don’t care about all destinations, but just places you are likely to fly. Well, we don’t know much about you in particular, DSN reader, but we might assume you tend to go where the people are. So, we redid the analysis restricting to the following airports, which fall within the major metropolitan areas of the US and Canada:

New York, NY
Newark, NJ
Los Angeles, CA
Long Beach, CA
Chicago, IL
Washington, DC
San Francisco, CA
Oakland, CA
San Jose, CA
Boston, MA
Philadelphia, PA
Dallas, TX
Miami, FL
Houston, TX
Atlanta, GA
Detroit, MI
Seattle, WA
Phoenix, AZ
Minneapolis, MN
Cleveland, OH
Denver, CO
San Diego, CA
Portland, OR
Orlando, FL
Saint Louis, MO
Tampa, FL
Pittsburgh, PA
Toronto, ON
Montreal, QC
Vancouver, BC

And here is that result:

flights.topmetro.sm.frompdf

Much the same.

As a side note, this was a lot of work after the kid went to bed. And it still isn’t perfect. Flight data are messy. Tools used (an incomplete list):

(*) Here are the raw results before merging the codeshare flights with the big airlines. EWR, JFK and LGA combined, only airlines with more than 200 departures per week:

Heuristics for dodging Swiss customs

CUES CUSTOMS OFFICERS USE

cues

When leaving an international airport, you usually see many people walking straight through customs, but occasionally see a passenger whose suitcases are being searched by customs officers. How do the customs officers decide which people to stop? It must be a case of cue-based inference. This leads to two natural questions. What are the cues? How are they used?

By interviewing the chief customs officer at a major international airport, Thorsten Pachur and Gianmarco Marinello found out what the common cues are in a paper called Expert intuitions: How to model the decision strategies of airport customs officers?:

  • flight origin
  • gender
  • nationality
  • age
  • amount of luggage
  • eye contact with officer
  • clothing
  • speed of gait

Which cue values point in which direction? For smuggling drugs, the relationships go like this (positive values are more indicative of a drug smuggler).

tab1

Customs officers have beliefs about the predictiveness of these cues. The bar graph at the top shows how diagnostic officers felt each cue to be (on a scale where 1=not diagnostic and 100=highly diagnostic). As you can see experts and novices have different opinions about the validities of cues (e.g., experts know that eye contact tells you nothing, which is good news for me since I rarely make it, like, ever).

Now, you’re a customs officer. Here’s your task:

task

On analyzing many such decisions made by actual customs officers, Pachur and Marinello can predict which strategy people are using to decide:

  • WADD – Weighted additive (combine everything after giving each cue a weight)
  • EQW – Equal weight (combine everything but give every cue equal weight)
  • TTB – Take The Best (use Gigerenzer and Goldstein’s 1996 Take-The-Best heuristic)
  • Guess – Guess

As in many such studies, those who have done the task a lot (experts) drop into a lexicographic TTB strategy:

ABSTRACT

How does expertise impact the selection of decision strategies? We asked airport customs officers and a novice control group to decide which passengers (describedon several cue dimensions) they would submit to a search. Additionally, participants estimated the validities of the different cues. Then we modeled the decisions using compensatory strategies, which integrate many cues, and a noncompensatory heuristic, which relies on one-reason decision making. The majority of the customs officers were best described by the noncompensatory heuristic, whereas the majority of the novices were best described by a compensatory strategy. We also found that the experts’ subjective cue validity estimates showed a higher dispersion across the cues and that differences in cue dispersion partially mediated differences in strategy use between experts and novices. Our results suggest that experts often rely on one-reason decision making and that expert–novice differences in strategy selection may reflect a response to the internal representation of the environment.

Subway riders’ quirks

A TRAIN OF DECISIONS

sw

The New York Times reports on a report, written by the MTA, about the decisions of subway riders:

Now, the daily seating calculations of subway riders have been recorded for academic use, as part of an observational study conducted by researchers of the Metropolitan Transportation Authority. A draft of their report, published on the Web site of the Transportation Research Board, drew on data collected over three weeks in late winter 2012.

It’s full of gems, such as:

“Customers do change seats as seats become available due to passengers disembarking,” the report said, in language riders would be unlikely to use: “but seat-change maneuvers incur utility costs (movement effort, and risk of desired seat becoming occupied midmaneuver).”

When a subway car has more passengers than seats, the study found that an average of 10 percent or more of the seats were not taken. And even when a subway car is less than half-filled, the authors found that a small percentage of riders would inevitably choose to stand.

Riders prefer seats near a door, the authors said, and demonstrate “disdain for bench spots between two other seats.”

2013 guide to the American Marketing Association job market interviews for aspiring professors

Filed in Gossip ,Jobs
Subscribe to Decision Science News by Email (one email per week, easy unsubscribe)

EVERYTHING YOU EVER WANTED TO KNOW ABOUT THE AMA INTERVIEWS (2013 edition)

PhD students in Marketing, Psychology, and Economics should send their “packets” out by the fourth of July in the hopes of lining up interviews at the annual AMA Summer Educator’s Conference. Each year DSN reprints this sort of “what to expect while you’re applying” guide, first published here by Dan Goldstein in 2005. This year, Dave Hardisty and Abby Sussman have co-authored this guide with Dan to bring it up to date 2013. “I” will refer to Dan in what follows.

SHARE YOUR OWN AMA TIPS
I am more than happy to publish AMA tips, updated information, or just AMA horror stories as part of this post. You can reach me at dan at dangoldstein dot com and let me know if you want to be anonymous or nonymous.

WHY AM I WRITING THIS?
I have seen the Marketing job market turn happy grad students into quivering masses of fear. I want to share experiences and provide a bit of advice to make the whole process less mysterious.

WHY SHOULD ANYONE LISTEN TO ME?
Dan went on the AMA job market in the mid 2000s. Dave and Abby, who thoroughly revised this guide, went on in 2012. As a professor, Dan’s conducted a bunch of AMA interviews and been a part of dozens of hiring decisions. Together, we’ve been on the candidate end many AMA interviews, and experienced numerous campus visits, face-to-face interviews, offers, and rejections.

HOW TO GET INTO THE AMA JOB MARKET
First, at least a couple months before the conference, find where it will be. It’s called the American Marketing Association Summer Educator’s Conference. Strange name, we know. Insiders just call it “The AMA”. Get yourself a room in the conference hotel, preferably on the floor where the express elevator meets the local elevator for the upper floors. You’ll be hanging out on this floor waiting to change elevators anyway, so you might as well start there. Next, create a list of schools at which you would like a job. You can find the top 100 schools ranked by journal publications at: http://jindal.utdallas.edu/the-utd-top-100-business-school-research-rankings . Next, apply to each one you’d go to. In the past, this involved physically mailing application packets, but these days nearly everything is electronic. Some schools have online application portals, and others will take applications by email. How do you find out which one? Hopefully, the school you are applying to will have posted a job at ELMAR (see http://ama-academics.communityzero.com/elmar; and subscribe to their mailing list) or elsewhere, which will specify how to submit your application. Other times, you’ll need to get in touch with a department administrator to find out how to apply. It’s a good idea to apply to schools you like even if they say they aren’t hiring. Sometimes things change suddenly (a tenured faculty member unexpectedly moves to another school), and the only thing you risk is your time.

On this topic, one recent market participant wrote us saying: “Sometimes during an AMA interview the people you are interviewing with might tell you up front that they are not planning to hire someone in CB (consumer behavior) and that they are just interviewing you because they wanted to hear about your work (or, more generally, to get to know the star candidates on the market). This happened to me with at least one school, and it almost makes you NOT want to try seriously (i.e., to use that interview as a “break” from the more consequential interviews). However, I would strongly advise candidates to take all their interviews seriously, even with schools that claim not to be hiring CB candidates. First of all, the interview is an opportunity for schools to learn about candidates’ research and therefore an additional opportunity to invest in one’s reputation. But, more importantly, sometimes they end up changing their minds and giving you a fly-out anyway, despite what they initially said about not hiring CB candidates (this happened to me).”

http://www.marketingphdjobs.com/ has general information about the Marketing job market, including a job board showing who is advertising jobs. This site also has information about the times when jobs are announced. Different schools require different materials for the application, involving some combination of: cover letter, CV, teaching statement (and/or teaching evaluations), research statement, letters of recommendation (roughly three), your “job talk” paper, and one or two additional publications.

It’s useful to have your advisor (or if that’s not feasible, his/her assistant) send an e-mail with your materials directly to their colleagues at each of your top choice schools. Ideally you would have your letter writers e-mail their recommendations directly to your advisor so the information is aggregated. This will not take the place of applying through a school’s official online system, but will bring attention to your application before it arrives. This is also useful for schools that are slow to set up their official application, or who are uncertain about whether they’ll be hiring. Some candidates will send hard copies of these packets to all of the schools, although this practice seems to be dwindling.

Note that the CV for AMA takes a special format, including an extended abstract of your “job talk” paper, so you should find an example to model your CV after. It’s helpful if your letters of recommendation come from faculty in marketing. You need to demonstrate your commitment to the field of marketing, so it’s also ideal to have publications in marketing journals, or at least something under review at a marketing journal.

It’s invaluable to have an “application buddy” who is also on the job market. You can share notes about who is hiring, how to apply at each place, etc. It also just makes the whole process more fun, to have a friend along for the ride.

With the advent of electronic submissions, the “marginal cost” of additional submissions is extremely low, and schools are facing a flood of applications. Last year, the median number of applications sent by each candidate was 60, and this will probably increase next year. Each school can only interview a limited number of candidates at AMA (perhaps 20 or 30), so they need to be selective: they are not necessarily looking for the best candidates, but rather the best candidates that would accept an offer from their school (over and above offers from other schools). For this reason, “lower tier” schools will often not give interviews to “upper tier” candidates, because they believe that there is little chance the upper tier candidate would actually accept an offer from them. Therefore, you need to find a way to communicate why you are interested in that school in particular. The best way is if you have a contact at that school (or your advisor has a contact). You should let them know that their school is a high priority for you, and why. Another strategy is to get the word out that you are targeting a particular region (such as the west coast or midwest) or type of school (big city vs rural location, small vs large school, etc). Thus, even though your real priority is probably to get a job *anywhere*, it’s good to specialize a bit to give yourself a competitive advantage. Likewise, once you get an AMA interview or a fly-out, it’s good to have a host of reasons prepared to explain why you are excited about that school in particular. Keep in mind that information about your preferences that you tell to one school may get back to other schools as well. For that reason, it’s best to come up with unique reasons why you like each school that do not detract from your ability to credibly like others.

If you are submitting by email, it’s a good idea to follow up and confirm that they have all your application materials. Sometimes email applications get lost (this happened to a friend of ours at his top-choice school), and once the AMA interviews are scheduled, it may be too late.

As for deadlines: the rough deadline is July 4th, but there is a lot of variability. A few schools have earlier deadlines and will have scheduled all their interviews by the 4th, whereas other schools will be behind schedule and won’t even post a job opening until after the 4th. Within reason (beginning mid-June), there’s an advantage to submitting materials sooner rather than later. Ethan Pew adds “July 4 is still largely the target for sending out packets, however schools seem to be moving to more of a just-in-time process. [In 2011], 53 positions were announced between July 4 and AMA. There were also 24 positions announced the last week in June — and presumably those schools didn’t expect packets by July 4. In total, those 77 positions accounted for 40% of the jobs announced prior to AMA last year.”

THEN WHAT?
Wait to get calls or emails from schools wishing to set up AMA interviews with you. These calls may come in as late as one week before the conference. Often they come when you are sitting outside having a drink with friends. Some schools will not invite you for totally unknown reasons. You may get interviews from the top 10 schools and rejected from the 30th-ranked one. Don’t sweat it. Again, this is the land of total and absolute unpredictability that you’re entering into. Also, know that just because you get an interview doesn’t mean they have a job. Sometimes schools don’t know until the last minute if they’ll have funding for a post. Still, you’ll want to meet with them anyway. Other times, schools are quite certain they have two positions, but then later university politics shift and they turn out to have none.

When the schools call to set up an AMA interview, you will have some flexibility in scheduling. Should you put your top schools at the beginning of the weekend, the end, or somewhere in the middle? Common advice is to put your less preferred schools on the beginning of the first day, because this gives you a chance to practice before the “important” ones. Then you can put your top choice schools early (say 10am, not 8) on the second day of the conference, so you’ve had some time to practice, but you and the interviewers can still be fresh and energized. While it’s nice to schedule strategically, it’s very difficult since you have no idea which schools you’ll ultimately be hearing from, and calls come in over time. Don’t worry if it’s not possible to schedule everything perfectly- there’s no real magic to this. For example, the beginning of the weekend is also when interviewers will be freshest, and a primacy effect could help you: in fact, we know a candidate that put his top school first, and eventually got a job offer from them.

After the AMA, you’ll hopefully get “fly-outs,” that is, offers to come and visit the campus and give a talk. This means you’ve made the top five or so. Offers for fly-outs generally come within a week or two of AMA. Actual job offers start in late October, and the market has generally cleared by Thanksgiving. There’s a second job market that happens after all the schools realize they’ve made offers to the same person. Some schools over-correct for this and don’t make offers to amazing people who would have come. We need some kind of market mechanism to work out this part of the system.

THE “IT’S ALL ABOUT FRIENDSHIP” RULE
Keep in mind that you will leave this process with 1 or 0 jobs. Therefore, when talking to a person, the most likely thing is that he or she will not be your colleague in the future. You should then think of each opportunity as a chance to make a friend. You’ll need friends to collaborate, to get tenure, get grants, and to go on the market again if you’re not happy with what you get. It’s a good idea to send thank-you emails after AMA, to maintain contact, show your interest in the school, and express your appreciation. After all, the AMA interviewers have sacrificed their weekend to talk to you.

HOW DO YOU FIND OUT IN WHICH ROOM TO INTERVIEW?
The schools will send you e-mails either a few days in advance, or the night before telling you which room to go to. Many profs ask the hotel to make their room number public, but for some reason many hotel operators will still not give you the room number.

HOW TO TREAT YOURSELF WHILE THERE
My sponsor gave me the advice of not going out at night and getting room service for breakfast and dinner. This worked for me. Also, the ridiculously high price of a room-service breakfast made me feel like I was sparing no expense, which I found strangely motivating. However, as this guide has gotten more popular, many people are ordering room service breakfast, and there were reports at last year’s AMA that the hotel was overwhelmed with orders and breakfasts were delivered quite late as a result.

HOW DO THE ACTUAL AMA INTERVIEWS GO?
At the pre-arranged time you will knock on their hotel room door. You will be let into a suite (p=.4) or a normal hotel room (p=.5, but see below). In the latter case, there will be professors with long and illustrious titles—people you once imagined as dignified—sitting on beds in their socks. The other people in the room may not look at you when you walk in because they will be looking for a precious few seconds at your CV. For at least some people in the room, this may be the first time they have concentrated on your CV. Yikes is right. Put the important stuff early in your CV so nobody can miss it. You can expect anywhere between one and nine faculty members to show up usually it will be between three to five. Some of them may take cell phone calls in the middle of your interview. Don’t take It personally.

THE SEAT OF HONOR
There will be one armchair in the room. Someone will motion towards the armchair, smile, and say, “You get the seat of honor!” This will happen at every school, at every interview, for three days. I promise.

THE TIME COURSE
Allow extra time to get to your interview: all the candidates are traveling from one room to another at the same time, and the elevators can get pretty backed up. When you arrive, there will be two minutes of pleasant chit-chat. They will propose that you talk first and they talk next. There will be a little table next to the chair on which you will put your flip book of slides. You will present for 30 minutes, taking their questions as they come. Usually 20 minutes of scripted material will take you through the full time since you’ll be interrupted the whole way through. But you should be prepared to talk for up to 35-40 minutes for quiet groups, or sessions where only one faculty member shows up. They will be very nice. When done, they will ask you if you have anything to ask them. You of course do not. You hate this question. You make something up. Don’t worry, they too have a spiel, and all you need to do is find a way to get them started on it. By the time they are done, it’s time for you to leave. The whole experience will feel like it went rather well.

PREDICTING IF YOU WILL GET A FLY-OUT
It’s impossible to tell from how it seems to have gone whether they will give you a fly-out or not. Again, this is the land of staggering and high-impact uncertainty. They might not invite you because you were too bad (and they don’t want you), or because you were too good (and they think they don’t stand a chance of getting you and they don’t want to waste a precious fly-out on you). The latter fact means that “playing hard to get” is a bad idea. Interviewers will be friendly because everyone wants you to like their school, regardless of whether or not they will invite you for a fly-out.

DO INTERVIEWS DEVIATE FROM THAT MODEL?
Yes.
Sometimes instead of a hotel room, they will have a private meeting room (p=.075). Sometimes they will have a private meeting room with fruit, coffee, and bottled water (p=.025). Sometimes, they will fall asleep while you are speaking (p=.05). Sometimes they will be rude to you (p=.025). Sometimes a key person will miss an early interview due to a hangover (p=.025). Sometimes, if it’s the end of the day, they will offer you alcohol (p=.18, conditional on it being the end of the day).

HOW YOU THINK THE PROCESS WORKS
The committee has read your CV and cover letter and looked at your pubs. They know your topic and can instantly appreciate that what you are doing is important. They know the value of each journal you have published in and each prize you’ve won. They know your advisor and the strengths she or he instills into each student. They ignore what they’re supposed to ignore and assume everything they’re supposed to assume. They’ll attach a very small weight to the interview and fly you out based on your record, which is the right thing to do according to a mountain of research on interviews.

HOW THE PROCESS REALLY WORKS
The interviewers will have looked at your CV for about one minute a couple months ago, and for a few seconds as you walked in the room. They will never have read your entire cover letter, and they will have forgotten most of what they did read. They could care less about your advisor and will get quite annoyed that you didn’t cite their advisor. They’ll pay attention to everything they’re supposed to ignore and assume nothing except what you repeat five times. Flouting 50 years of research in judgment and decision-making, they’ll attach a small weight to your CV and fly you out based on the interview and their gut feeling.

IF ENGLISH IS NOT YOUR MOTHER TONGUE
Your ability to speak English well won’t get you a good job, but your inability to do so will eliminate you from consideration at every top school. Understand that business schools put a premium on teaching. If the interviewers don’t think you can communicate in the classroom, they’re probably not going to take a chance on you. If you are just starting out and your spoken English is shaky, my advice is to work on it as hard as you are working on anything else. Hire a dialect coach (expensive) or an english-speaking actor or improviser (cheaper) to work with you on your English pronunciation. In the Internet age, it’s quite easy to download samples of English conversational speech, for instance from podcasts, for free. It’s also very easy to get a cheap headset and a free audio recorder (like Audacity) with which to practice.

TWO WAYS TO GIVE YOUR SPIEL
1) The plow. You start at the first slide and go through them until the last slide. Stop when interrupted and get back on track.
2) The volley. Keep the slides closed and just talk with the people about your topic. Get them to converse with you, to ask you questions, to ask for clarifications. When you need to show them something, open up the presentation and show them just that slide.
I did the plow the first year and the volley the second year. I got four times more fly-outs the second year. Econometricians are working hard to determine if there was causality. I would not attempt the volley unless you are generally considered to be good with words.
A middle ground is to have a shorter presentation prepared, with many backup slides that you can turn to in response to audience interest or specific questions. This helps the audience understand that you’ve thought about the project deeply, that your responsive to their specific interests and feedback, and that there’s more to support your argument than the prearranged script, but it’s easier for some to execute than a straight volley.
What do you use to show your slides? Many candidates print out slides and put them into a presentation binder, such as one of these: http://tinyurl.com/c46ob64 . Insert two copies of each slide into the binder so you can see a copy from the back, and the audience can see another from the front. Hand-outs are also a good idea, as a supplement to your slides. Bring lots of hand-outs, because it’s common to let them keep one copy. Keep in mind that AMA slides are not the same as a typical PowerPoint presentation. People should be able to read your slides from the back of the room. I recommend no smaller than size 40 font, and larger is better.

Lately, people have talked about showing slides on an iPad, but I don’t know anyone that has actually done this.

HOW TO ACT
Make no mistake, you are an actor auditioning for a part. There will be no energy in the room when you arrive. You have to be like Santa Claus bringing in a large sack of energy. The interviewers will be tired. They’ve been listening to people in a stuffy hotel room from dawn till dusk for days. If you do an average job, you lose: You have to be two standard deviations above the mean to get a fly-out. So audition for the part, and make yourself stand out. If you want to learn how actors audition, read Audition by Michael Shurtleff.

SOCIAL SKILLS MATTER
From the candidate’s point of view, everything is about the CV and the correctness of the mathematical proofs in the job market paper. However, for better or for worse, extra-academic qualities matter. Here are two examples. 1) The Social Lubricant factor. Departments get visitors all the time: guest speakers, visiting professors, job candidates, etc. Some departments are a bunch of folks who stare at their shoes when introduced to a new person. These departments have a real problem: they have nobody on board who can make visitors feel at ease, and sooner or later word starts to spread about how socially awkward the people at University X are. To fix such problems, departments sometimes hire socially-skilled types who know how to make people comfortable in conversation, and who know how to ask good questions during talks. Also, interviewers assume that people who can talk a good game will be star teachers. 2) The Soft Sell factor. Many people succeed in academia not because they are often right, but also because they are masters of making other people feel like they aren’t wrong. Defensiveness or determination to embarrass when responding to critique is an effective way to blow an interview.

HAVE A QUIRK
One of the biggest risks facing you is that you will be forgotten. Make sure the interviewers know something unusual about you. My quirk is that I worked internationally as an actor and theater director for over a decade; I even had a bit part in a Conan O’Brien sketch on TV. It has nothing to do my research, but people always bring up this odd little fact when I do campus visits. Some bits of trivia are just more memorable than others.

DON’T GIVE UP
Never think it’s hopeless. Just because you’re not two SDs above the mean at the school of your dreams, it does not mean you’re not the dream candidate of another perfectly good school.
Many candidates don’t realize the following: The students are competing for schools but the schools are also competing for students. If you strike out, you can just try again next year. I know a person in Psychology who got 70 rejections in one year. I know a person in Marketing who was told he didn’t place in the top 60 candidates at the 20th ranked school. The subsequent year, both people got hired by top 5 departments. One of them is ridiculously famous and considered among the smartest people in Marketing!

RUMORS
Gossip can mess with your chances. Gossip that you are doing well can hurt you because schools will be afraid to invite you if they think you won’t come. Gossip that you are doing poorly can hurt you because schools that like you will be afraid to invite you if they think no one else does. Sometimes people will ask a prof at your school if you would come to their school, and the prof will then ask you. To heck with that. Just say that if they want to talk to you, they should talk with you directly.

The danger of rumors can be summed up by the following story. At ACR in 2003, I was having a beer with someone who confessed, “you know, my friend X at school Y told me that they want to hire you, but they’re afraid your wife won’t move to Z”. I was single.

Kurzban: Are All Dictator Game Results Artifacts?

DARN THAT IS INTERESTING

Rob Kurzban has an interesting write up of this article on the dictator game here.

ABSTRACT

Economic experiments are increasingly being used in a number of research areas and are a major source of data guiding the debate surrounding the nature of human prosociality. The degree to which experiment behavior accurately reflects external behavior, however, has long been debated. A number of recent studies have revealed just how remarkably sensitive participants are to cues of a lack of anonymity. Similarly, others have suggested that the very structure of the experimental context induces participants to choose prosocial options. In order to truly create anonymous conditions and to eliminate the effects of experimental contexts, participants must not be aware of their participation. Here, I present the results of a natural-field Dictator Game in which participants are presented with a believable endowment and provided an opportunity to divide the endowment with a stranger without knowing that they are taking part in an experiment. No participants gave any portion of the endowment to the stranger. Baseline frequencies of prosocial behaviors exhibited under experimental contexts might therefore be substantially inflated compared to those exhibited under natural contexts.

A WHOLE BOOK ABOUT IT

If you’ve ever wondered about The Heuristics Debate, this is the book for you.

If you have no interest in heuristics, you’ll probably be happier with another book. How about one of these?

Wait, sorry, those were all about heuristics too. If you are not into heuristics, maybe you’d like this book instead:
