By whom? Not very likely by people targeted.

Suppose my Facebook friends share a terrible article (the one that comes to mind is one that came out a few years ago about male and female ELO distributions in chess). I can criticize my friends for sharing the article; I can criticize the authors for writing the article; I can criticize the editors for accepting the article. This shifts the social landscape slightly.

Focusing instead on 'publish or perish' seems like mistaking the proper scope of my actions, as I am not the Science Czar nor am I likely to become one.

I would suggest that the framework of influence/manipulation/memetics/control is going to be more useful here than the framework of free trade.

Influence is a more specialized description of these sorts of information markets, yes. But the point of that paragraph is that it is not just empirically the case that people will listen to each other and adopt opinions with minimal original seeing, but that it is obviously rational for them to do so in almost all contexts. The language and models of specialization and trade make that more clear.
