Wundt

• Weakness of introspection is people believed that wundts methods were fundamentally unreliable. FE behaviourist suggested that his methods relied on ‘non observable‘ methods. Although you could report on conscious experiences the processes themselves were unobservable.TMB approach failed due to lack of reliability of methods with other psychologists unable to replicate hide other results in other labs. Therefore wasn’t was unable to provide objective evidence whereas behaviourists could.
• another weakness of introspection is that is not accurate examination of one’s unconscious mental state. FE Nisbett and Wilson suggested that a person may be implicitly racist which influences ways they react to members of different ethnic groups but not consciously aware that they are.TMB introspection would not uncover implicit stereotypes so we have little knowledge of preocesses underlying our behaviour and attitudes. Therefore it doesn’t accurately measure people‘s behaviours and lacks validity
