I flagged the comment:
"Most of the things are done." No they're not. Not even close. You are so far from being done that it is impossible to know just how incredibly far from being done you are. ( en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect )
left under a new user's first question because of the negative connotations that the Dunning–Kruger effect carries. I see its use in this particular comment as borderline snark, and certainly in no way a helpful comment to proved a welcoming environment to a new user.
@Ghedipunk when leaving your comment, the message "Devarsh Newar is a new contributor. Be nice, and check out our Code of Conduct" appeared right above where you were typing, perhaps you missed that? [uhoh]
Thank you, @uhoh, for calling my attention to the Code of Conduct once again. I've reviewed it, and I stand by my statement. The most helpful that anyone can be, in light of these 3 (unpunctuated) sentences, is to point out that they demonstrate a clear and undeniable inconsistency: One can not be ignorant of any of the fundamental equations of rocketry, and also have most "things" done for a trans-Martian trip except the formula[s]. This person is at the low end of the Dunning--Kruger Effect, and the most humane thing to do is to make sure they are educated.
Yes, I can throw a wall of text at them, but that isn't helpful or nice. Rather, the nicest thing that I can conceive of is to ask them to go find a resource that isn't strangers online who are seeking Fake Internet Points (tm), but people who care about them as themselves, and to realize that they don't have as firm a grasp on the topic as they may believe that they have.
We have a lot of positive and welcoming ways to help new users with their first questions, I don't see how this is one of them. The question can be answered, editied, helpful comments left, etc.
The follow-on comments just confirm that the intended purpose of the first comment seems to be to "do people a favor by showing them just how ignorant they are".
I don't think this is a valid justification, or a good way to greet new users.
However, iinstead of the Dunning–Kruger borderline-snark comment being deleted, my flag was declined.
I think the comment should be deleted because it may make the OP feel bad, and because it shows other users that we can say borderline-condescending things to new users when we like. This comment is basically "what's wrong with you is..."-ing the OP. They've come to the site asking questions.
In what way is leaving this comment intact benefitting the OP, or improving the quality of the site? Conversely, in what ways might it encourage more "what's wrong with you is..."ing?
