A weakness of Wundt's research

-Some aspects would be considered unscientific by today's standards -Relied on ppts self-reporting their private mental thoughts, this is subjective and influence by personal persepctive. As well as this, they may have hide what they actually were thinking -Ppts may not have the same thoughts are everyone else they were testing, establishing would not have been possible -Suggest that some of Wundt's early efforts to study the mind were naive and would not meet the criteria of scientific enquiry
