It seems to be common in some fields to have papers with multiple co-first authors. How is this viewed in the general academic community? Do you think this is a just system to ensure that everyone gets due credit for a project or just a way to grab credit and just prevent authorship disputes within groups?
Full disclosure: I shared co-first authorship with two other authors on one of my papers (there were five authors total) and the listed order of the three first authors was literally determined by drawing from a deck of cards.
