Grandma Moses vs. Philip K. Dick (2); Gandhi advances

Yesterday’s most relevant comment came from Ben: Gandhi would have a far more interesting things to say about the current state of world politics, etc. The issues that Gandhi was known for (de-colonization, passive resistance) remain immensely relevant but with very different parameters than the 1920’s-1940’s. By contrast, Mother Teresa’s main mission (serving the poor) […] The post Grandma Moses vs. Philip K. Dick (2); Gandhi advances appeared first on…

Mohandas Gandhi (1) vs. Mother Teresa (4); Hobbes advances

March 15, 2015

For yesterday, we didn’t get much in the way of comments, so I’ll have to go with this comment by Jonathan: Hobbes is the Arnold Schwarzenegger of philosophers. Any time someone feels he’s been killed off, he’ll be back. Tolstoy is the Buster Keaton of novelists. Widely admired, widely studied, and just about obsolete in […] The post Mohandas Gandhi (1) vs. Mother Teresa (4); Hobbes advances appeared first on…

First off, I just want to say I made a mistake yesterday dropping Alan Turing in favor of Ed Wood. As Zbicyclist put it, “Ed Wood’s best thoughts are probably on the screen.” And that’s not good at all! So, sorry for eliminating one of the exciting speakers from the list. I’m also thinking of […] The post Thomas Hobbes vs. Leo Tolstoy; Rock advances appeared first on Statistical Modeling,…

De-weaponizing reproducibility

A couple of weeks ago Roger and I went to a conference on statistical reproducibility held at the National Academy of Sciences. The discussion was pretty wide ranging and I love that the thinking about reproducibility is coming back to statistics. There was pretty widespread support for the idea that prevention is the right way to approach
