Is there formal data demonstrating that academic pressures (e.g. "publish or perish") has been increasing over time? Did anybody draw a rough calendar of which laws and rules changed at which time, resulting in the rise of such academic pressure?
In some universities of my (current) country of residence (Chile), various bibliometrics-based restrictions (as opposed to checking the content of a research or research proposal) are exerted on academics and students to insure they publish (e.g. an academic needs to have published 7 journal articles in "Web of Science" journals in the last 5 years in order to be allowed to direct a PhD student; a PhD student must have published two such journal articles before being allowed to defend; a Master student must have submitted two such journal articles before being allowed to defend), in addition to various incentives (e.g. bonus salary money from various entities for each article published into such a journal). Such coercive measures and incentives have increased over time (e.g. the threshold to be allowed to guide PhD students used to be 5 articles in the last 5 years, the monetary amounts paid for each publication is regularly increased, etc.).
World-wide, the "publish and perish" pressure of academia has been cited as a cause for various cases of scientific fraud, and it is my understanding that it is seen as having increased over time, but I could not find any formal claim to that.
For a study of malpractices encouraged by "publish or perish" policies, I would like to document formally whether academic policies have increased the pressure to publish on academics, and whether such change of policies can be correlated with observable changes in academic behaviors (e.g. as was done in the article Citation gaming induced by bibliometric evaluation: A country-level comparative analysis for Italian publications regarding one Italian regulation).
