How people interpret probability through words

2 Shares

In the early 1990s, the CIA published internal survey results for how people within the organization interpreted probabilistic words such as “probable” and “little chance”. Participants were asked to attach a probability percentage to the words. Andrew Mauboussin and Michael J. Mauboussinran ran a public survey more recently to see how people interpret the words now.

The main point, like in the CIA poll, was that words matter. Some words like “usually” and “probably” are vague, whereas “always” and “never” are more certain.

I wonder what results would look like if instead of showing a word and asking probability, you flipped it around. Show probability and then ask people for a word to describe. I’d like to see that spectrum.

Street network orientation in major cities

1 Share

Using OpenStreetMap data, Geoff Boeing charted the orientation distributions of major cities:

Each of the cities above is represented by a polar histogram (aka rose diagram) depicting how its streets orient. Each bar’s direction represents the compass bearings of the streets (in that histogram bin) and its length represents the relative frequency of streets with those bearings.

So you can easily spot the gridded street networks, and then there’s Boston and Charlotte that are a bit nutty. Check out Boeing’s other chart for orientation of major non-US cities.

See also Stephen Von Worley’s color-coded maps and Seth Kadish’s charts from 2014 that showed the same thing but used Census data instead of OpenStreetMap.
