It's hard to tell honestly. I studied psychology for two years in uni, and I dropped out rather disillusioned about the field. Some of my least favorite aspects included:

  - Acknowledgement by our professors that P-hacking (pruning datasets to get the desired results) was not just common, but rampant

  - One of our classes being thrown in limbo for several months after we found out that a bunch of foundational research underpinning it was entirely made up (See: Diederik Stapel).

  - Experiencing first-hand just how unreproducible most research in our faculty was (SPSS was the norm, R was the exception, Python was unused).

  - Learning that most psychology research is conducted on white psychology students in their early/mid-twenties in the EU and US. But the findings are broadly generalized across populations and cultures.

  - Learning that the DSM-IV classified homosexuality as a mental disorder. Though the DSM-V has since dropped this. 

The DSM-V is still incredibly hostile towards trans people through a game of internal power politics and cherry-picked research. It's really bad honestly.

Though I do generally hold psychologists in high regard (therapy is good), I'm not particularly impressed by psychology as a science. And in turn don't necessarily trust the DSM all that much.
