Don’t, don’t, don’t, don’t . . . We’re brothers of the same mind, unblind

Hype can be irritating but sometimes it’s necessary to get people’s attention (as in the example pictured above). So I think it’s important to keep these two things separate: (a) reactions (positive or negative) to the hype, and (b) attitudes about the subject of the hype. Overall, I like the idea of “data science” and […] The post Don’t, don’t, don’t, don’t . . . We’re brothers of the same…

Saying things that are out of place

Basbøll points us to a column by Michael Shermer, a journalist and self-described skeptic who’s written a lot about skepticism, atheism, etc. Recently, though, Shermer wrote of an event that “shook [his] skepticism to its core”—it was a story about an old radio that didn’t work, then briefly started to work again, then stopped working.
