The "friends-of-friends" network guarantees that influential academic figures can effectively mark their own homework, distorting the scientific record and -- for good measure -- undermining the principle of evidence-based clinical practice
An inherent class system empowers privileged professionals to punch down hard on patients who have the temerity to challenge the quality of their clinical work.
In psych fields, this includes the power to dismiss critics as mentally unwell.
Dismissals by psych professionals are frequently couched in centuries-old tropes relating to "hysteria", a proving-the-negative proposition that plays on stereotypes of feminine weakness and irrationality
Even out-and-out pseudoscience will get published in major journals if the authors are deemed to be VIPs ("Very Important Professionals"). Status is more important than science.
Editors, many of whom happily boast about standards, don't seem to care
Sometimes the favouritism is not even concealed. In-group papers get soft-soaped and happily published, while critical ones are not even sent out for review

Ultimately, what is needed is a highly structured, even mechanised, system of review that focuses on objective data and truly independent adjudication. Risk of bias should be presumed to be high, and safeguards implemented accordingly.
And as we go, public scrutiny and analysis are absolutely essential. Not just clinical info and statistics, but also critical evaluations of how information gets produced and why it comes to be promulgated.
