Human Computation & The Joy of Work

Sherry Leung sent me a link a very interesting site this week. Free Rice is a charity site that engages the user with a progressively more challenging vocabulary quiz.  For each correct answer, the site's sponsors will donate 10 grains of rice to the United Nations.  When you combine feeding your brain with a wholesome distraction and the warm feeling of watching your rice bowl fill up, it's pretty addictive.  And it's hard work!

This got me thinking more generally about the power of the "human computer" to accomplish other tasks, and I rediscovered Luis von Ahn, an Assistant Professor at Carnegie Mellon.  He was obsessed with all the human computational time "wasted" playing Solitaire, etc., and suggested that image recognition and tagging could be done by humans if it was placed in the context of a competitive game. This was the inspiration for the ESP Game, later licensed by Google Image Labeler.

The CAPTCHA technology was another von Ahn innovation (he's a MacArthur Fellow).  That's the maddening distorted text challenge boxes used to defeat spam bots.  He decided that this too was wasted human energy, and recently introduced reCAPTCHA.  Instead of serving up random letters, your challenge phrases are now snippets of text from a project to digitize old books.  You are providing the human intelligence where OCR has failed. 

I think there is some kind of metaphor here in terms of other experiences we create for consumers.  We are so scared of making the customer do any work- everything is supposed to be seamless and easy.  But sometimes, as the adage goes, hard work is its own reward.  Especially when you can create something of value for the customer.

Interesting post - at thehungersite.com, you can donate 1.6 cups of food - free - just for clicking once on the site. In 2006, visitors donated more than 52,000,000 cups of food to the needy. Since 1999, visitors to the site have given more than 300,000,000 cups of staple food. It's worth a click every day.

Call me cynical, but it's also a good way to get clicks on your site. Do any of these sites offer actual proof they're actually making the donations they say they are? Complete transparency is so important in social media.

If these folks offer proof of their gifts, then I guess I'm the dumb one. (Wouldn't be the first time.)

It never occurred to me that there might be something going on at these clicks-for-donations sites. But it seems like it would be more trouble than its worth to try and cheat the public.

If there's any obfuscation, it's often that a donor will set a cap on the total amount they will donate (e.g. Red), rather than failing to give anything at all.
