Tessier-Lavigne debacle underlines case for more transparent authorship

Excellent article and well done Paul for raising this. However, Institutions do not sufficiently enforce the ethics of authorship and indeed reward those who appear to publish prolifically but who clearly have no contribution to the paper nor expertise in the area. Multi-author consortia need to be investigated: where author/collaborator lists run to hundreds or even thousands, it stretches credulity to call all of the named authors. Yet, I have seen careers flourish on this sort of behaviour.
