On Wednesday I posted the full list of the almost 900 posts submitted to Open Lab. As part of the process that I'm using to distribute the posts to my awesome reviewers, I've assigned each post a primary category. (Clearly, many of the posts can easily fit into more than one category, but based on the post, the blog's general content - as far as I know or can tell - or whatever other information is available to me, I've picked one to be primary.)

Here's the breakdown of the posts by category (click to enlarge):

Some trends are obvious and expected, such as that there are more life science posts than physical science posts. I was somewhat surprised by the extent to which the Psychology/Behavior/Cognition category surpassed the Biology category. What trends do you see? Anything expected or surprising?
