  • Imagine you are trying to infer the structure of a tree by only know the positions of its leaves. Now imagine doing the same, but only 1/100 of the leaves are above ground.

    It’s only a small fraction living organisms which remain alive today. Most species and families which have ever been are extinct. And most are so old we could never do DNA work on them. Among the living, we can do some good DNA work and that’s made a huge difference. But then go back far enough and there are just massive nonconformities.




  • Data is not magical, however much you wish it to be.

    I’ve built maps estimating how much of your lawn you are watering at at 15cm pixel resolution. Techniques to count how many cars per driveway are parked at evening hours. How much water, per hour, being used by every address in a county.

    I have seen dashboards developed by collaborators who have access to near real time data regarding the physical positions of hundreds of millions of devices.

    Just because its the highest resolution data that you know about, doesn’t mean its the highest resolution data which exists.


  • I think for this map to be salvaged you need to fix the denominator and not use political boundaries for aggregation. Hexagons or raster because the entire point is to make it arbitrary. The formula would need to be something like (Auto Deaths per capita)/(Road Miles Traveled Per capita), or maybe (Auto Deaths per capita)/(Sum of length of roads per cell).

    Regardless, its still a population map because the denominator gets really small in rural areas, and the map still doesn’t tell us anything about how safe or dangerous roads are.
