How Wikipedia destroyed the greatest reference book of all time?

Here’s the law: Any project, if broken down into sufficiently small, predictable parts, can be accomplished for awfully close to free.

Jimmy Wales led the tiny team at Wikipedia that destroyed the greatest reference book of all time. And almost all of them worked for free.

The Encyclopaedia Britannica was started in 1770 and is maintained by a staff of more than a hundred full-time editors. Over the last 250 years, it has probably cost more than a hundred million dollars to build and edit.

Wikipedia, on the other hand, is many times bigger, far more popular, and significantly more up-to-date, and it was built for almost free. No single person could have done this. No team of a thousand, in fact. But by breaking the development of articles into millions of one-sentence or one-paragraph projects, Wikipedia took advantage of the law of the Mechanical Turk. Instead of relying on a handful of well-paid people calling themselves professionals, Wikipedia thrives by using the loosely coordinated work of millions of knowledgeable people, each happy to contribute a tiny slice of the whole.

Dan Ariely: “If you want to demotivate your employees, just ignore them and their efforts”

We created a sheet of paper with a random sequence of letters on it and asked the participants to find instances where the letter S was followed by another letter S. We told them that each sheet contained ten instances of consecutive Ss and that they would have to find all ten instances in order to complete a sheet. We also told them about the payment scheme: they would be paid $0.55 for the first completed page, $0.50 for the second, and so on (for the twelfth page and thereafter, they would receive nothing).

In the first condition (which we called acknowledged), we asked the students to write their names on each sheet prior to starting the task and then to find the ten instances of consecutive Ss. Once they finished a page, they handed it to the experimenter, who looked over the sheet from top to bottom, nodded in a positive way, and placed it upside down on top of a large pile of completed sheets. The instructions for the ignored condition were basically the same, but we didn’t ask participants to write their names at the top of the sheet. After completing the task, they handed the sheet to the experimenter, who placed it on top of a high stack of papers without even a sidelong glance. In the third, ominously named shredded condition, we did something even more extreme. Once the participant handed in their sheet, instead of adding it to a stack of papers, the experimenter immediately fed the paper into a shredder, right before the participant’s eyes, without even looking at it.

We were impressed by the difference a simple acknowledgment made. Based on [a previous] experiment, we expected the participants in the acknowledged condition to be the most productive. And indeed, they completed many more sheets of letters than their fellow participants in the shredded condition. When we looked at how many of the participants continued searching for letter pairs after they reached the pittance payment of 10 cents (which was also the tenth sheet), we found that about half (49 percent) of those in the acknowledged condition went on to complete ten sheets or more, whereas only 17 percent in the shredded condition completed ten sheets or more. Indeed, it appeared that finding pairs of letters can be either enjoyable and interesting (if your effort is acknowledged) or a pain (if your labor is shredded).

But what about the participants in the ignored condition? Their labor was not destroyed, but neither did they receive any form of feedback about their work. How many sheets would those individuals complete? Would their output be similar to that of the individuals in the acknowledged condition? Would they take the lack of reaction badly and produce an output similar to that of the individuals in the shredded condition? Or would the results of those in the ignored condition fall somewhere between the other two?

The results showed that participants in the acknowledged condition completed on average 9.03 sheets of letters; those in the shredded condition completed 6.34 sheets; and those in the ignored condition (drumroll, please) completed 6.77 sheets (and only 18 percent of them completed ten sheets or more). The amount of work produced in the ignored condition was much, much closer to the performance in the shredded condition than to that in the acknowledged condition.

This experiment taught us that sucking the meaning out of work is surprisingly easy. If you’re a manager who really wants to demotivate your employees, destroy their work in front of their eyes. Or, if you want to be a little subtler about it, just ignore them and their efforts. On the other hand, if you want to motivate people working with you and for you, it would be useful to pay attention to them, their effort, and the fruits of their labor.

Throw less at the problem

When things aren’t working, the natural inclination is to throw more at the problem. More people, time, and money. All that ends up doing is making the problem bigger. The right way to go is the opposite direction: Cut back.

So do less. Your project won’t suffer nearly as much as you fear. In fact, there’s is a good chance it’ll end up even better. You’ll be forced to make though calls and sort out what truly matters.

Eight queens puzzle made with jQuery

The eight queens puzzle is the problem of placing eight chess queens on an 8×8 chessboard so that none of them can capture any other using the standard chess queen’s moves. The queens must be placed in such a way that no two queens attack each other. Thus, a solution requires that no two queens share the same row, column, or diagonal.

The puzzle was originally proposed in 1848 by the chess player Max Bezzel, and over the years, many mathematicians, including Gauss, have worked on this puzzle and its generalized n-queens problem.

I had to create a C++ version of this program and I thought it should be fun to make a web version of the puzzle, so I made it with jQuery and CSS. You can play it clicking in the next link: eight queens puzzle.

The game’s code is open through Creative Commons By-SA (like the rest of this blog), and the queen image is from Wikimedia Commons (under GFDL). Enjoy it!
