I do not think so. Most researchers are likely to be good. However, a few researchers might adopt other means for publication which when detected not only brings disgrace to them but apperently also to the institutions in which they work.
Publication of false result may have a good connection with predatory journals. Chances of it is minimum in standard journals, even it also doesn't guarantee 100% true. Also, the observed results/ theory which we are using and assuming true today may become a special case of a new theory in near future.
I agree with Subir and Dibakar. It depends on the journal in question. some journals are only for financial gains others are for the quality of the publication.
