I don’t think we fully realize the suggestion bias we have when we open an observation that already has an identification. The mental path of least resistance is to say, “Oh, I see how that thing could be that species,” rather than look closely at the picture and go through the rigors of identifying from scratch.
I wouldn’t want to remove the ability to see comments and observations in an observation, but for those who want the challenge, I propose:
Create an optional setting that hides existing comments and identifications from search views and in observation pages, and a button in each of those places to show them. For the search returns, a button in the corner of the thumbnail; for the observation pages, a button at the head of the comments/identification feed.
My hypothesis is that using this setting would cut down on erroneous Research Grade identifications by removing suggestion bias.
(As an aside, since iNat happens in a database, it has the capability to track the results, which would be a great research/thesis project for any sociology researchers out there.)
