For fun replace 'psychology' with 'quantum physics'. Is it also not science?
1. Contradicts some natural laws
2. Is not explained by the natural world except in reference to itself (often due to changes beyond a certain scale)
3. Not necessarily testable against the empirical world (yet)
4. Always up for debate (so good there) as is psychology.
5. Falsifiable or not depending on your stance, in a similar way to psychology, in that there is a lack of complete understanding. The swan example in the wiki article could not be applied for instance because all of the facts and observations are not available (again... yet.)
As for Kahneman (and many other psychologists), if you believe that he starts with the conclusion and refuses to change it regardless of the evidence developed during the course of the investigation, you may have skipped some very important parts of Thinking Fast and Slow. The book in question goes over many examples where the outcomes do not fit what is expected and lead to discovery.
Not arguing exclusively against what you are saying, just pointing out that there are fields that utilize the scientific method, which by their very nature are not entirely beholden to the current 'laws of science' often because their laws have not been fully laid down or explored yet.
Medical science moved past simply treating based on symptoms due to a great deal of work. Who's to say psychology can not do the same? There is still much to learn.
