Psychology had to be a science studying behaviour and mind of living beings.
There is a separate part of it studying specifically human behaviour and mind.
However, there is absolutely no any definition of how exactly human behaviour and mind different from non-human ones and how to separate one from another.
So, psychology can't even give an answer to the very basic question that obviously should precede any further study - is some person mind and behaviour human or non-human?
Psychology could have been very useful instrument to detect those with non-human behaviour and mind among us with scientific precision, but it was purposedly turned into pseudoscience bullshit to not even allow that question.
A simulation? Where would the server be? Is it real? What of the data inside? Server real, data fake?
No answers found in that theory so far.
Agree on the rest, although sadism is practiced by animals on those other animals not bound by the same moral law (a cat and mouse have 2 different sets of moral law for each other's kin, for example, and it's 'good' for the cat to use the mouse as target practice)
