A PACKING LIST AND MORE

Esquire recently posted some of Anthony Bourdain’s travel tips. Some good stuff there. Seeing the list reminded the editorial team at Decision Science News that we’ve always wanted to do a post on this. We travel a lot.

A PACKING LIST SAVES US TIME AND PREVENTS ERRORS

This packing list is based on one that David Allen (of Getting Things Done fame) shared. We’ve modified it to suit our needs. We pack from a list every trip. It gets packing time down to 20 minutes and zero errors. Here is the PDF (source for editing), ready to print four-per-page.

GETTING A PHONE WITH FREE GLOBAL DATA WAS GAME CHANGING

Since we moved from Verizon to t-mobile, our phone now works everywhere in the world and gets free data everywhere in the world. Much better than schlepping around a second unlocked phone and switching sim cards.

INFLATABLE NECK PILLOWS MAKE US FEEL GOOD

For a long time, we looked at those silly looking people with their neck pillows and felt superior. Then we tried one. They really make you feel better. We’ve tried four kinds, including some expensive ones, but our favorite is the Samsonite Inflatable Neck Pillow.  It folds up to an impossibly small size and disappears so you won’t look a doofus marching around the airport with one tied to your bag.

IT’S NOT THE JET LAG, IT’S THE SLEEP DEPRIVATION

More information.

BOARDING TIME CAN BE UP TO 10 MINUTES BEFORE THE PUBLISHED BOARDING TIME

This matters if you have status with the airline and get to board first. If you show up at the time on the ticket, you may be boarding with group 4.

WE PREVENT LIQUIDS FROM LEAKING THIS WAY

Two things. 1) Squeeze a little air out 2) Put a little square of plastic wrap over the mouth of the bottle. Screw the cap on. Voila.

WE LIKE RETRACTABLE USB CORDS

Like these. Keeps things tidy and untangled. Apologize to the squirrels who were nesting in your bag.

WE LIKE INTERNATIONAL PLUG ADAPTERS WITH BUILT-IN USB PORTS

Like these. Use your computer and charge your phone at the same time. Amaze your friends with what you can charge in one outlet, anywhere in the world.

WE LIKE COMPRESSION BAGS

Like these. They make your stuff, especially winter stuff, take up less space. And they act as laundry bags for the return trip. And they will keep a wet bathing suit from getting the rest of your stuff wet. And you don’t need a vacuum cleaner to use them. Just seal and roll. The air escapes through magical one-way valves. Not recommended for things that wrinkle easily. BTW, dry cleaning bags do a pretty good job of keeping things wrinkle free.

MEMORIZING OUR PASSPORT NUMBER WAS WORTH IT

If you travel internationally a lot, this is more useful than it sounds. You get asked for it surprisingly often, and you never feel like digging up your passport when filling out forms. We even have advice on how to remember long numbers. Lock it in once and you’re good for life.

SWIM DON’T RUN

And avoid packing an extra pair of shoes for exercise. We read about this in an interview once.

WE TRY NOT TO BOOK FLIGHTS THAT DEPART BETWEEN 11AM and 10PM

This helps us avoid flight delays.

 WE ALWAYS RETURN HOME WITH ZERO FOREIGN COINS

And this is how we do it.

If you have tips, feel free to share them in the comments.

A DOZEN YEARS OF ESCAPE DATA FROM NEW YORK STATE

Click to enlarge

The recent prison break in upstate New York got us wondering how long prison escapes tend to last. We found some data on prison escapes in New York State. See the dot plot above.

We then found a table in the Atlantic, which cites this paper, on perhaps more skillful inmates who managed to stay on the run a bit longer, though 80% of them were back in prison inside a week.

The upshot from both analyses is the same: if you escape from prison, you’re probably going to be re-captured within a day.

CORRELATION WITH REPUBLICAN VOTING IN THE 2012 PRESIDENTIAL ELECTION

Click to see a larger, stripped down version

In light of the good news today that the Supreme Court ruled that same-sex couples have the right to marry in the United States, we thought we’d look at when same-sex marriage laws became effective by state (if they did at all) before today.

Noting that same sex marriage is a dividing issue between the left and right in the US, we thought we’d compare the date of when same-sex marriage laws become effective in each state with each state’s Republican (two-party) vote share in 2012. Results are below.

Click to enlarge

Note that California’s same-sex marriage law was effective in 2008, then it was overturned, and then made effective again in 2013. We went with the earlier date because you’ve got to chose something.

The next question is “what about the states that were added by the Supreme Court decision today”? We made a second plot, below, in which we put today’s date for those states in the “effective date” column. The result is pretty much the same. See at the top of the post the ribbom plot contributed by David Lallemant in the comments.

It is interesting to note that none of the plurality Romney-voting states had same sex marriage laws in effect before 2014.

A couple last things. You probably want to see the data, because the graph can be hard to read.

CREATE: CROWDSOURCING EVIDENCE, ARGUMENTATION, THINKING AND EVALUATION

The Intelligence Advanced Research Projects Activity (IARPA) will host a Proposers’ Day Conference for the Crowdsourcing Evidence, Argumentation, Thinking and Evaluation (CREATE) Program on June 30, 2015, in anticipation of the release of a new solicitation in support of the Program. The Conference will be held from 9:00 AM to 4:00 PM EDT in the Washington, DC metropolitan area. The purpose of the Conference will be to provide introductory information on CREATE and the research problems that the Program aims to address, to respond to questions from potential proposers, and to provide a forum for potential proposers to present their capabilities and identify potential team partners. This announcement serves as a pre-solicitation notice and is issued solely for information and planning purposes. The Proposers’ Day Conference does not constitute a formal solicitation for proposals or proposal abstracts. Conference attendance is voluntary and is not required to propose to future solicitations (if any) associated with this Program. IARPA will not provide reimbursement for any costs incurred to participate in this Proposers’ Day.

BACKGROUND AND PROGRAM GOALS
CREATE aims to improve analytic thinking by combining structured reasoning techniques with crowdsourcing. CREATE will develop and test methods to help dispersed groups of individuals identify and evaluate the structure and content of arguments in relation to alternative hypotheses. Intelligence analysts, along with professionals in other fields, assess competing hypotheses in light of multiple considerations, including reasons, evidence and assumptions. Reasons and evidence often differ in credibility and diagnosticity. CREATE will develop (1) structured methods to elicit and aggregate the elements of an argument and (2) ways to crowdsource the use of these methods, so that many individuals can collectively develop and refine an argument. The methods will be capable of treating reasoning involving quantitative and qualitative information. The CREATE Program expects to draw upon the strengths of academia and industry through collaborative teaming. It is anticipated that teams will be multidisciplinary and might include social and behavioral scientists, experts in informal logic, and computer scientists.

REGISTRATION INFORMATION
Attendees must register no later than 6:00 pm EDT, June 23, 2015 at

https://events.signup4.com/CREATEPDRegistration_June2015.

Directions to the Conference facility and other materials will be provided upon registration. No walk-in registrations will be allowed.

Due to space limitations, attendance will be limited to the first 250 registrants. If there are more registrants than available seats, priority will be given to the first two registrants from each organization. All attendees will be required to present government-issued photo identification to enter the event. Non-U.S. citizens will be required to present passports.

ADDITIONAL INFORMATION
The afternoon will include unclassified presentations and poster sessions to provide an opportunity for attendees to present their organizations’ capabilities and to explore teaming arrangements. Attendees who wish to present organization capabilities for teaming opportunities may submit a request through the registration website. Details on the presentation and poster formats, and the procedure for submitting a request to present, will be provided after approval to register for the Conference has been granted. Time available for presentations and posters will be limited. Therefore, presentations will be limited to the first 15 registered respondents who request an oral presentation, and posters will be limited to the first 15 registered respondents who request a poster presentation. These presentations are not intended to solicit feedback from the Government, and Government personnel will not be present during the presentations.

This Proposers’ Day is intended for participants who are eligible to compete on the anticipated BAA. Other Government Agencies, Federally Funded Research and Development Centers (FFRDCs), University Affiliated Research Centers (UARCs), or any other similar organizations that have a special relationship with the Government, that gives them access to privileged or proprietary information, or access to Government equipment or real property, will not be eligible to submit proposals to the anticipated BAA nor participate as team members under proposals submitted by eligible entities. While such entities are not prohibited from attending the Proposers’ Day, due to space limitations, preference will be given first to those organizations that are eligible to compete.

INCOME PERCENTILES AND INCOMES PAINT DIFFERENT PICTURES

The amazing team at the New York Times have a “You Draw It” feature in The Upshot in which readers try their hands at drawing a graph. The graph should show the probability of a child going to college based on their parents’ percentile in the income distribution.

As a cool added feature, after people took their guesses, they could see, in shades of red, the other guesses people had taken and compare it to the actual graph.

SPOILER ALERT: You can see the true answer at the bottom of this post. If you want to try your hand at guessing, click through to the NY Times and guess before proceeding.

One way to interpret this relationship is that for every percentile increase in parental income, the probability of college enrollment increases by a constant amount, which might seem somewhat surprising. Even the NY Times editors were surprised by this linear relationship, and the data they collected showed that other people were, too.

Jake Hofman and I wondered “what if people didn’t take the X-axis literally, what if they thought about it as something like log income or income (instead of percentile in the income distribution)?” Percentiles are tricky. They’re buckets with equal numbers of people, but those people can have very different incomes. What would the graph look like if the X-axis were income? Would this relationship be more intuitive to readers?

Jake scraped some income percentile data from whatsmypercent.com and we eyeballed the probability data from the chart at the NY Times. This enabled us to look at the probability of going to college based on income, which tells somewhat of a different story. In these plots, the size of the each point corresponds to the number of people in it.

The change you get by adding $10,000 a family’s income matters considerably for those earning between $10,000 and $100,000 (which the vast majority of Americans do), and matters much less outside that range. At the same time, it’s considerably more difficult for lower income parents to increase their income by this amount.

R CODE FOR YOUR CODING PLEASURE

THE SMART MONEY SENSED SOMETHING WAS UP

As you probably know, the well-known Science article on attitudes toward gay marriage by LaCour and Green has been called into question (even by its second author) and will likely be retracted by the journal.

We were amazed and impressed to learn today that statistician Andrew Gelman had a sense that something was up with the article soon after it was published. In a December comment in the Washington Post, Gelman was flabbergasted by the size of the claimed result:

What stunned me about these results was not just the effect itself—although I agree that it’s interesting in any case—but the size of the observed differences. They’re huge: an immediate effect of 0.4 on a five-point scale and, after nine months, an effect of 0.8.

A difference of 0.8 on a five-point scale . . . wow! You rarely see this sort of thing. Just do the math. On a 1-5 scale, the maximum theoretically possible change would be 4. But, considering that lots of people are already at “4” or “5” on the scale, it’s hard to imagine an average change of more than 2. And that would be massive. So we’re talking about a causal effect that’s a full 40% of what is pretty much the maximum change imaginable. Wow, indeed.

and

And this got me wondering, how could this happen? After all, it’s hard to change people’s opinions, even if you try really hard. And then these canvassers were getting such amazing results, just by telling a personal story?

and

I say all this not to “debunk” or dismiss LaCour and Green’s work: I think their experiment is really cool, and it’s amazing they found such strong and consistent effects. What I’m trying to do here is understand these findings in light of all the other things we know about public opinion.

That said, Gelman didn’t cry foul. He accepted the result as real and tried to come up with reasons why it might have happened. But he sensed something was unusual, even back in December, and we’re quite impressed by that.
