[Agnosco]

For anyone interested in this field should take a look at the work of Ulrik William Nash. I had the pleasure of completing a course led by Ulrik as well as writing an internal paper with him as my supervisor:

His main paper on wisdom of crowds and skew, which is rigorous (free): https://journals.plos.org/plosone/article?id=10.1371/journal...

Short presentation: https://www.youtube.com/watch?v=yqTbzSHi-UQ

The paper above is worth reading for anyone interested in the utilization of collective wisdom.
