I recently read a paper, which showed a mathematical model for performance scaling of research groups in different scientific branches. I'm aware you were originally asking for smaller "cognitive tasks" and project-like group-processes in the comments, but output and quality of publications/patents is probably anyway a better and more objective measure on a ...

It's a big topic. The relationship between group size and performance on a cognitive task is going to vary by several factors. Here are a few thoughts: The form of interdependence adopted by the group on the task will matter. When everyone can just work independently (e.g., taking calls in a call centre), then it makes sense that output would increase ...

The following are just my thoughts on what seems to make sense from first principles. I don't have a detailed understanding of what is standard practice in the wisdom of crowds literature. I've also only given what you've written a basic read. I.e., enough to understand the broad question, but not enough to follow exactly what you've done. Let $y_i$ be the ...

The fMRI Data Center (www.fmridc.org) was one such repository. About ten years ago it was a requirement for publication in the Journal of Cognitive Neuroscience that you submit your full fMRI dataset to the fMRIDC. This requirement was only around for a few years, but they ended up having 120+ datasets before the grant funding ran out. The archive is ...

This might be better suited as a comment, but I'm not allowed to post such. I went through the nice list collected by Craig Bennett: nitrc.org: Data has been preprocessed, but there is no complete list of what has been done, and how the data has been collected. Maybe the information is hidden in the previous publications. Anyway, I would not use it for ...
