Expertise as exception handlingPosted: April 24, 2014 at 5:03 pm in cognition, sports
A few months ago, I wrote a post claiming that expertise was doing difficult tasks consistently and Rif challenged me on that. And I’ve been thinking about it over the past few months and have another model I’m going to throw out there: expertise as exception handling.
One example of this is my experience as both a skier and a snowboarder. I am an expert skier, having skied on and off since I was a kid, and an intermediate snowboarder, having picked it up a couple years ago. I spent most of the winter skiing in anticipation of skiing trips to Japan and Baldface. After I got back from Baldface, I got on the snowboard for the first time in a year, and it was interesting to see how my mindset changed. On my skis, I am confident I can handle any terrain and conditions, even people cutting me off while I’m speeding down the hill. On the snowboard, I can comfortably go down any groomed run, no matter how steep, but as soon as the conditions are uneven (e.g. moguls) or off-piste or if people around me do something unexpected, I freak out because I don’t know how to adjust quickly.
Another example comes from volleyball, where a previous post noted how better teammates put me in a better position to succeed. If I’m given a good set, I can hit it down. If a ball is spiked right to me, I can dig it. However, if the ball is a little off, I’m not as reliable. Meanwhile, the expert players can take a ball hit out of their reach, and if they can get one knuckle on the ball, they’ll pop it up perfectly to their partner. And if the set is five feet off the net, they find a way to hit it down anyway.
A last example comes from bridge. I’m an intermediate bridge player at best, but I am subscribed to the bridge players list at Google. The discussions on that list are often around rare hands, where there’s no standard play or bid to cover the situation. The experts on the list debate about how to handle such situations, and many of them have arcane bidding systems to cover all sorts of unusual hands. These are situations I could never figure out how to handle with my basic understanding and the standard bidding system, but they have played enough to figure out how to handle these corner cases.
In all of these examples, the difference between the intermediate player and the expert is that the expert can handle a wider variety of rare situations. The intermediate may be almost as good as the expert the majority of the time, but in unusual situations, the greater experience of the expert allows them to do something when the intermediate is frozen by uncertainty.
This also explains why mere repetition is not enough to acquire expertise. Mastery requires deliberate practice, where one is continually and deliberately testing the edge of one’s ability. By setting up artificial practice situations which don’t come up normally, one gains the ability to handle these exceptional situations whereas repeating the standard situations would not help. It was described once to me as the difference between ten years of experience, and the same year of experience ten times.
I don’t think my advice changes from my last post on expertise, which suggested that deliberate practice was how to gain consistency, but I like this model better. Expertise is learning about how to handle anything that an activity can throw at you, and do it with confidence because you’ve seen it all before. This is also consistent with Gary Klein’s Recognition-Primed Decision Model. Build up your intuition and expertise by getting oneself into more difficult and rare situations so that you can handle them better in the future.
