 Behaviourists were also concerned with the lack of statistical information collected with a particular interest in certain behaviours and a perceived bias from subjects whilst relaying their stories.Lloyd Morgan, a British psychologist and student of Romanes, removed the anecdotal methodologies from his work to avoid criticism and to ensure an objective systematic speculation and research approach.He was in favour of associating the mental states of animals by interpreting animal behaviour through introspection, though he was cautious of how humans over-intellectualise animal behaviour, as in the case of Clever Hans.
