Zen in the Art of Citizen Science

When it comes to online participation in collective endeavors, 99% of us typically take a free ride.

From Wikipedia and YouTube to simple forum discussions, there is a persistent pattern known as the 90-9-1 principle. This means, for example, that of Wikipedia users, 90% only view content, 9% edit existing content, and 1% actually create new content. Inequity in effort, of vastly more people accessing collective information than contributing to it, is a persistent feature of online engagement.

Large-scale citizen-science projects, such as where ordinary people assist in genuine scientific research, when facilitated by the Internet, may not be exempt from the 1% rule of thumb. Despite the promise of app and web development to assist citizen scientists in data submission, the “build it and they will come” approaches fail because not enough people contribute to make such projects useful. Are there examples of online citizen-science projects that succeed on a big scale despite unequal participation? If so, how?

For answers, let’s take a look at eBird, a free, online citizen-science project run by the Cornell Lab of Ornithology. eBird began in 2002 and quickly became a global network within which bird watchers contribute their bird observations to a central database. Over 2.5 million people have engaged with eBird. Of those, 150,000 have submitted data (6%) and 25,000 (1%) have submitted 99% of data. The 1% includes the world’s best birders as well as less skilled but highly dedicated backyard bird watchers. For everyone else, eBird is free information, and there is lots of it.

Is eBird successful?

eBird is successful scientifically. Since 2006, eBird has grown 40% ever year, which makes it one of the fastest growing biodiversity datasets in existence. It has amassed over 140 million bird observations, with observations from every country on the planet. Researchers have written over 90 peer-reviewed publications using eBird.

eBird is successful for conservation. The last two State of the Birds reports, which relied on eBird data to examine species occurrence, habitat types, and land ownership at a level of detail never achieved before, inform decisions of the US Fish & Wildlife Service and the US Forest Service. The Nature Conservancy uses eBird data to identify which rice farmers in the Central Valley of California they should ask to flood their fields at the particular right time for migrating waterfowl.

eBird is successfully engaging bird watchers. eBird doesn’t ignore the 99% who don’t submit data. The most frequent use of the eBird database is by handheld apps that people use to figure out where to go birdwatching.

Recently I was scheduled to give an opening provocation for a workshop on technology for citizen science at the British Ecological Society meeting in London. A “provocation” is intended to provoke thoughts, emotions, and epiphanies in order to instigate deep discussion, in this case about how to use technology to make citizen science successful. Are more apps for submitting data really the answer? Should we try to break the 1% rule or engage the 99% in other ways? To prepare, I went to Steve Kelling, the head honcho of eBird. In Jack Nicolson style, he can deliver a one-liner that blankets a room in thought, which is then invariably followed by a succession of light-bulb moments of understanding. When I asked Kelling to explain the success of eBird, he sagely said, “When eBird stopped doing citizen science, it got successful.” (score!).

How could eBird succeed at citizen science by not doing citizen science?

Kelling’s counter-intuitive riddle reveals the Zen in the art of citizen science.
