Metadata matters!
If you submit a preprint to PsyArXiv, to ensure smooth acceptance, don't forget to fill out the metadata correctly.

I propose a behavioral conceptualization of personality functioning (PF) that reframes the construct in terms of learned self-related repertoires rather than inferred inner structures.

We might be at a stage where systematic reviews without checks of trustworthiness become a problem in itself - even a danger to patients, as these reviews are considered as highest level of evidence and the foundation of guidelines and clinical practice
Currently busy with updating a systematic review and have the impression that the flood of "clinical studies" from certain countries is intensifying - results too good to be true: enduring effects (usually uncommon), no drop-out, perfectly balanced sample sizes etc.
