Your assessment of psychology is flawed in several ways. The main concern of psychological research isn't to help someone. It's to understand how/why organisms think and behave under certain conditions. Psychological research can be conducted using the scientific method like any other science field. To say "Psychology", as a whole, is similar to snake oil, ignores thousands of perfectly sound findings. Fraud is certainly not unique to the field of psychology. Nor are the pressures to publish positive findings.

Your final thoughts about 'life outcomes from genetics' is incoherent.
