Not to suffer from 'ad hominem' but are you on the Austim Spectrum Disorder spectrum?
Because if so, I'll understand that it would take a huge amount of work to try to show to you that things aren't just black and white.
"Psychology isn't real science": Please explain to me how this is the case. Things are rarely black and white. The sciences lies on multiple spectrums based on how you categorise them. E.g. Math is generally known as the 'purist' science...but there is huge differentiation between math and say biology.
Specific to psychology, there was this amazing graph (that it is killing me that I cant find) that clearly showed where comparative place to other sciences based on things like (laws vs theories, peer evaluated articles, dependence on citation etc etc). The graph showed that psychology is closer compared to other STEM disciplines than other social sciences.
I quickly found a link to a pdf deck that provides data on the issue (although its a horribly constructed presentation)

If that doesnt work try googling (Is Psychological Science a STEM Discipline?) its a presentation from psychology.ucdavis.edu.
So yeah, psychology = science.
Unfortunately psychology suffers from a rich history of pseudoscience and questionable ethics. This has had a lasting effect on how people construe psychology (you'd be surprised with how many people think that Freudian based practices are still wide spread). The domain of psychology is broad, with many sub disciplines (as the study of behaviour and mental processes of humans, its going to be varied; just as biology is broken up into its relevant domains).
Now. Often people might join these two things together in some way to come to a negative generalised understanding of what psychology is. E.g. "Well, like, I met this paranormal psychologist, who was also really interested in Freud's theories and like, and I once heard that like, one psychologist named zimbardo did some fucked up studies......I think psychology is a load of shite, its not a real science'.
Another example would be 'I played Final Fantasy X-2. The storyline sucked and the job Thief sucked too. Therefore, I hate all Final Fantasy games/ All RPGs/ etc'
You quoted my post, and then wrote alot about percentage based gains and then said..."It doesn't tell us why we do things, and therefore can't be used to change what things we do with certainty."
I really don't know what to say to this except, durh? As you mentioned humans are incredibly complex, of course there is going to be variance. Does it make it any less legitimate to study something that doesn't have certainties? If you are looking to understand the complexities of behaviour in yes or no/ black or white you aren't going to find it, and as a discipline psychology doesn't claim to answer such things in such a manner.
I personally find it exciting to try to consider the different variables involved in complicated behaviours (such as drug abuse, or non-optimal medication adherence). For example, today I'm looking into how prior buprenorphine treatment experiences may influence current or prospective buprenorphine treatment outcomes. E.g. How does having experience of using the drug and going through the treatment process effect how you will go through it again.
I'd also wonder about your understanding of what neuroscience is. Psychology and neuroscience aren't either/ or. Within Psychology (or within Neuroscience) there are overlapping branches (Cognitive neuroscience for example).
I'd posit that you saw the word 'neuro' and the word 'science' and came to the conclusion that it must be a really good science because it has the word neuro in it.
