I think the degree of supportiveness among peers varies considerably across disciplines. Peers in some fields are extremely competitive and hyper-critical of each other, despite being capable researchers, and they unwittingly undermine the reputation of their entire field. Peers in some other fields support each other, giving constructive comments when reviewing papers and grant proposals, ... always searching for the silver lining in a cloudy submission. These fields prosper. It is an interesting question in Game Theory, what strategy is optimal for academic peers.
