justaddwater57··on Lyft’s plan to take control of its maps and its future
Agreed. A lot of drivers in NYC (where I'm also based) seem to have multiple devices in the car. Maybe there's some flawed data gathering if a driver still is using the native Lyft app but running navigation on a separate device?
justaddwater57··on What college rankings really tell us
Interesting that Tulane is called out here as an example:

"One common statistic used to evaluate colleges, for example, is called “graduation rate performance,” which compares a school’s actual graduation rate with its predicted graduation rate given the socioeconomic status and the test scores of its incoming freshman class.... Tulane, given the qualifications of the students that it admits, ought to have a graduation rate of eighty-seven per cent; its actual 2009 graduation rate was seventy-three per cent. That shortfall suggests that something is amiss at Tulane."

Anyone else think that those numbers for the 2009 graduating class has anything to do with the fact that Hurricane Katrina hit during the first few weeks of '09's freshman year, forcing students at Tulane (which is located in New Orleans) to take leaves of absences or transfers?

Just goes to show, in addition to inherent biases, rankings also don't capture extenuating circumstances that can have drastic short term effects that go unnoticed.
