Leveraging The Long Tail

Psychology tends to get to data from a medium number of trials, about 100, from a medium number of subjects, about 30. Occasionally, psychology, particularly perception and sensation research, will get a large number of trials, say 10,000, from a few subjects, say 4 (including the first author).

What happens if you go to the edge. How about a large number of trials (a million trials would be a good start) from one person? How about 1 trial from a large number of people (again, I would start with a million)? Those edges are easier than ever to access via the internet. Using the "long tail" of the internet has been prototyped in science by the Galaxy Zoo project. It is time for psychology to join the game.
