A fairly recent answer here offering havening as a therapy has only upvotes. But a quick internet search found a rather brief and contested Wikipedia page alleging havening is pseudo-scientific.
So what's the status of this technique/therapy in psychology? E.g are there meta-analyses showing that it's effective? And how is the quality of primary research assessed in this area? E.g. is the sub-field reasonably free of publication bias (which nowadays is also assessed in the better-off meta-analyses)?
