I'm not explaining everything but a true scientific hypothesis is something that can be tested by statistics, research, or some scientific method. A hypothesis that isn't testable isn't much of a hypothesis.
You were ironic because you keep talking about true science, and how psychology often brings poor research to the table. Yet here you are talking about the same thing you complain about. That's irony.
Feel free to be done with me. You are the one constantly quoting posts and responding with paragraph of borderline nonsense at times. I'm not saying you are right it wrong, and I think it's cool how into your theories you are, and how you love learning. But you need to start being more open to all research, don't discount entire fields, and for the love of god learn how to be more brief
