I don’t understand how you draw that conclusion from what I have said…
No. Again, I struggle to see how you conclude that…
This is my opinion:
If a user puts an ID, and mistakenly clicks the wrong taxa in the list, or mistypes the name and erroneously picks up the wrong taxon in their ID, then they should delete it outright… It does not represent what they think the observation is of …
If they change their mind, likely through the discussion on the observation or by gaining further input from outside the observation (such as looking up books or suddenly remembering a relevant character), then they should leave the original ID as withdrawn, as it still represents what they thought it was at that time, but the new ID represents what they think it is now.
If several users put different IDs, then that just represents the fact that there is dissention or difference of opinion about the ID. That dissention is either resolved via discussion, or remains to attest to the difficulty of identifying that particular type of observation.
