Despite my expression is clear-cut, I don’t want to make a big issue with the discussion about coarse IDs.
Sorry for this long response. Drafting a solution is long.
What is the big issue?
We need observations to be identified (the iNat added value) but there are too few identifications (all requiring some expertise, academic or empirical, and time) and there are more and more incoming observations. Yet, CV is available to help identifiers and has considerably improved for years.
The big issue is the difficulty for identifiers to find the observations they can ID efficiently. The big issue is the lack of support for CV-based filtering in the iNat web pages that filter observations (“Explore” and “Identify” pages). Imagine a checkbox to enable CV-based filtering in your search queries, so that you can find all observations of birds, with or without IDs. CV-based filtering by iNat (the true solution) would be better than phylogenetic projects (the palliative). It would require storing precomputed CV suggestions in the database, to make them readily usable for filtering.
Phylogenetic-projects-based CV-based filtering is not well enough integrated, as someone said, but it is usable right now. BTW, would you say that the unidentified observations are well integrated in iNat (not mentioning the placeholder)?
What’s my point with the discussion about the coarse IDs?
My point is to suggest you to use the palliative solution, until a better solution comes from iNat (if it comes), because our resources are limited and because we do need a more efficient identification work. For the same reason, my point is also to prevent wasting time.
I never said that coarse IDs are “bad” besides the placeholder issue. Moreover, as @DianaStuder mentioned, we are working on a solution to the placeholder issue, presently operating at small scale, and very promising. Will you like it? Made possible thanks to our expertise, will and efforts : I precise that not for self-promotion but to make you aware that you should not wait too long for a solution from iNat to some issues.
Lacking CV-based filtering, we are discussing the benefits of adding coarse identifications, concluding that you need these coarse IDs. Be aware that you express this need after considering the solution you got, and after being teached that some key aspects of the solution won’t change. This is a considerable bias in the vision.
With CV-based filtering, most coarse IDs become useless. (Just as computers, scanners and printers made carbon paper unnecessary in most circumstances). Of course, if a CV-based search for animals yields 5% of plants, we would ASAP identify these 5% as plants, to let the ID-based filtering have precedence over the CV-base filtering. When I say that 95% are useless, I mean that 5% are necessary. CV-based filtering can spare the tedious 95%.
