I participated in at least one seriously flawed psych study being done so someone could get a degree. I was not impressed.
I find the social stuff really fascinating. I seem to have an innate knack for it and I've taken college classes pertinent to that interest.
But I tend to seek out other types of information when trying to further my interest in understanding how people work. For example, negotiating, parenting and marketing are all areas that require you to understand how people work and are results oriented. You either get results or you don't.
A good test for how solid your hypothesis is: how well does it predict results? This is a general rubric. We know that Einstein's Theory of Relativity is superior to Newtonian gravity because it more accurately predicts planetary positions in the future.
Ability to predict outcomes accurately is fairly strongly tied to performance. So, to my mind, social things that are performance oriented set a higher bar than those that are generally descriptive in nature instead.
Psychology's ability to genuinely reform people with serious mental health issues is notoriously poor. This suggests it probably isn't on especially firm footing.
In addition to the above areas of interest, I also find some harder sciences, such as neurological studies, much more generally useful for understanding social phenomenon than most psych or sociology things I've seen. I've also found books written by primatologists very good.
A person I knew with a psych degree told me once that psych majors are mostly people who don't really understand people and are hoping to get a clue. Sadly, this hit a nerve for me. Some psych majors I've personally known fit that description all too well.
Maybe someday these areas of study will be better than they are currently. But their current state leaves much to be desired.
