Asking directly, because I could not find a straight answer: Why plausible mechanism is not evidence of effect

What changes if the standard account of plausible mechanism is wrong? I ask because I have been treating it as settled and I noticed this week that I could not say why.

Working through the consequences rather than the evidence, since others here are better placed on the evidence.

BPC-157's published evidence is overwhelmingly preclinical and mostly rodent. That is not a dismissal — it is the state of the literature, and any discussion that starts elsewhere is starting from something that is not there.

Picking up post #2: that is the part I would want checked first.

Publication patterns in the BPC-157 literature: a large proportion of the evidence comes from one research group. That is not necessarily wrong — one group can do excellent work — but it is worth noting when evaluating the breadth of support for a claim.

That has held every time I have looked, which is not the same as always.

an.kirchner, post #5: Reframing plausible mechanism slightly, because I think the disagreement is about the question rather than the answer. If the question is "does it happen", yes. If it is "how often", nobody here knows. Go to post

The documentation on plausible mechanism is better than this thread and I say that as someone who has posted in the thread.

Agreed on all of that, and I have nothing to add to it.
