Mange kliniske enheter bruker mange penger på å lære opp klinikere i nye metoder gjennom dyre kurs, bøker og veiledning. Mange av disse metodene mangler god dokumentasjon både med tanke på ønskede og uønskede effekter, sier Jan Ivar Røssberg.

(+) – Vi trenger ikke flere terapier. Vi trenger å finne ut hva som virker for hvem
Helsevesenet bruker altfor mye penger på å implementere nye metoder og behandlinger, før vi i det hele tatt har testet hvor godt de fungerer, sier overlege Jan Ivar Røssberg.

Very elegantly stated re conspiracy theorists: they don’t know what the don’t know, essentially:
“…a lower ability to accurately evaluate one’s knowledge”

Why are some people more prone to believe in conspiracy theories? Part of the answer may lie in metacognition, i.e., the ability to correctly estimate one's own knowledge about topics.

In psychotherapy, there are principles and there are preferences.
People tend to mistake their personal preferences for principles.
We have 400+ therapeutic modalities because of preferences, not principles.

Agree wholeheartedly that waitlist is not acceptable as a “placebo” condition. But I would take it further; waitlist is, perhaps with a few exceptions, never an adequate and acceptable control condition in trials examining treatments for mental disorders.
🧠 Takeaways for the field:
1️⃣ WL controls are no longer acceptable as “placebo”
2️⃣ Meta-analyses must stop lumping all “control conditions” together.
3️⃣ The “all psychotherapies are equal” myth needs retiring. The Dodo bird can finally rest in peace.

As most things in clinical psychology, the evidence for and the effectiveness of deliberate practice is exaggerated.
It turns out that the enthusiasm for the value of deliberate practice in psychotherapy training as an effective means of improving psychotherapy outcomes is not currently supported by a strong evidence base.

Must-read from the founders of @retractionwatch.com - about 85% of science is research waste, less than 50% of preclinical cancer research is replicable, and predatory publishers thrive: science has a serious quality control problem, and we're all in trouble.
