The Memory of Expertise (2011)

Llamas! I mean, sheep. I used to know a lot about these critters, back in the 1990s when I took this picture.

I was saddened last weekend to miss Dragon*Con’s Skeptrack in Atlanta—usually a highlight of my year—due to family and professional obligations. I knew months in advance that I wouldn’t be able to go, but there were a number of panels on topics close to my heart (on the scope of skepticism, its history, and its future) in which I would have loved to participate. (Luckily, I was able to watch some of those streaming live, completely for free—something some of you may wish to note for next year.)

But for my family and I, there was a major silver lining: the 144th Saanich Fair! Western Canada’s longest running agricultural fair, the Saanich Fair has been a tradition in my family since—well, since about the 110th Saanich Fair. There’s a special kind of life satisfaction that can only arise when you gaze in wonder upon prize pumpkins and blue ribbon pies. It casts a powerful nostalgic spell. The scents of hay, dust, and manure. The cooing rows of fancy pigeons, each more Darwinian than the last. Teams of draft horses. Supporting the Lions Club through the delicious means of volunteer-sold midway hotdogs. Hearing the screams of teenagers spun, flipped, shaken, and dangled upside down for no good reason. It’s all so familiar and magical—the pleasure of being transported back to childhood (especially now that I have a child of my own to share it with).

But that sense of time travel is an illusion. Which brings me to my topic for today: the fading of expertise. Read more

As many skeptics know by now, legendary skeptical trailblazer James Randi set off a firestorm last week with two Swift blog posts about global warming. His first post carried his strong suspicion that consensus science on climate change is incorrect, while his followup post wondered “whether we can properly assign the cause to anthropogenic influences.”

Skeptical bloggers were swift to respond. Critics (including PZ Myers, Orac, Sean Carroll, and James Hrynyshyn) chastised Randi for speaking outside his domain expertise; for dissenting from current consensus science; and for lending his name to the disreputable “Oregon Petition Project.” Others, like Phil Plait, corrected Randi while sensibly reminding us that “anyone, everyone, is capable of making mistakes.” And, inevitably, global warming deniers seized upon the event. (One headline, at Britain’s Telegraph.co.uk, gleefully crowed “James Randi forced to recant by Warmist thugs for showing wrong kind of scepticism.”) Read more
