From mine, it shouldn’t be. I see people hazarding guesses, and all it accomplishes is that it now takes three additional IDs to get to RG instead of just two. If a person really knows that little about nature, I had rather they take some time to learn rather than just randomly hazarding guesses.
I concur. The guesses I see, it looks like they ignored CV and just went with their gut.
When I don’t know something, I give it a broader ID that I do know. If I don’t know what that grass is, I’m not going to guess “Timothy Grass”; I’m going to say “Grasses.” When someone guesses, I have no reason to think that it is the “not knowing” type of ignorance; evidence suggests that it is the worse kind of ignorance, i.e., the “knowing what ain’t so.”
