Value of shared first authorships in a postdoc if in second place
I never truly understood what it actually means to be shared first author but placed in second place. Is there actually a difference between shared first and first and second author, if the order is pretty much still as if the first author were one?
I have just started my first postdoc where a couple of papers will likely have my PI as first first, and I will be co-first placed in second place. I am wondering about the value of these authorships. For context, the data are already there and I will be doing all the remaining work on the respective projects.
Thank you!
