Behavior and psychology is about predicting and analysing human behaviour.
However it is my belief that the "human element" makes such analysis open to large error
Perhaps i should explain what i mean by the human element.
It is a fact that no two human being are the same, it is clear that i differ from the the person next to me, this is clear from appearance but also from a one minute conversation with us. The inability to fix any variable from person to person is reallt what i mean by the human error
This is not to say that psychology is without it's uses. however i believe that any study produced on the subject is open to scrutiny because like, how accurate can any study be when it is impossible to hold the subject to a constant.
just look at a thermodynamic equation of state.
how accurate can any differential be if it is impossible to keep the constant..constant e.g if (dT/dP)v is evaluated how accurate can it be if v is impossivble to be kept constant
