Risk Visualization Theater

How to better communicate election forecasts — in one simple chart
Justin Gross | Monkey Cage blog [Washington Post]
November 29, 2016

Most folks were surprised by the results of the 2016 Presidential election and this was in part due to some of the rosy forecasts by some of the poll aggregators, like Huffington Post. But, even when a site had a forecast with a 30% chance of Trump winning, most people have trouble understanding that a Trump victory was possible. The explanation:

But certain representations of probability are more readily grasped than others. In particular, we have trouble understanding risk in terms of the “percent chance” but we do better when simple raw numbers of different outcomes are depicted visually.

Solution: Show the risk as a “Risk Visualization Theater.” Below are the representations of forecasts of victory for Trump via FiveThirtyEight, NYT Upshot, and Huffington Post Pollster. The filled theater seats (in black) represent the chance of a Trump victory. Clearly, the chance of that event happening don’t look so remote in the far left depiction, but look very unlikely as one moves to the right.

Missing girls in China maybe weren’t missing after all

China has had a highly unbalanced sex ratio at birth for years leading to an estimate of 30 to 60 million missing girls. The traditional explanation was male preference, exacerbated by the one-child policy, which led to sex selective abortion and/or infanticide. New research presents evidence that maybe the missing girls were never missing after all.

Using the TravelTime platform and some simple code, researchers can map how far people can travel in 30 minutes by public transportation from a specific address. This is more realistic than radius circles because these don’t take into account roads, bus routes, etc.

The TravelTime platform includes several countries, including US coasts.

Altmetrics: What are they and/or should I care?

Altmetrics are metrics and qualitative data that are complementary to citation-based metrics. Some argue that these metrics should be considered in tenure decisions, along with the more traditional metrics of publishing in a high impact journal with many citations. Almetrics cover a wider range of materials than just those in professional journals – websites, blogs, materials in repositories like figshare or GitHub. It also covers more than citations, such as views and downloads.

This blogpost from the Altmetric site, shows how Altmetrics can be incorporated into a traditional tenure document.

And an even more informative article on Altmetrics is a summary written by Yan Fu in a PSC news report:
