Curated lists of wild ideas in the sciences which anyone can submit to. The ideas are condensed, associated, and duplicated submissions paraphrased and combined. The purpose is to accumulate ideas that are new or unexplored in a format that attempts to prevent novel ideas from becoming lost in the crowd of repetitive thoughts. Then provide recognition for persons who successfully disprove ideas in the lists. Recognition for proofs can be acquired elsewhere.
There are lists of ideas that people can currently post to, but they are not curated to reduce duplication. Another function of the curator would be to properly index the entries by subject areas. "If you cannot find it, you don't have it, and you cannot use it." Properly formatted, recorded, indexed, and retrievable ideas can be searched quickly by new thinkers. Reducing duplication of efforts and helping researchers to connect with others interested in exploring in similar directions are further benefits.
How much would this cost to establish and maintain? How could it be financed over the long term? How often would you be likely to check your ideas against a list like this?
