negatives

• ignores role of genes and biology
• humanistic approach is not objective as it relies on subjective experiences.
• cannot be tested or falsified
• not scientific- actively against using empirical methods
• Humanism assumes that everyone's experience is valid which may not always be true.
• idiographic approaches lack generalisability and cant be used to create generalised laws about behaviour
• lacks objectivity, humanists believe we are all unique so there can never be an 'objective truth'. This means they cannot make claims about what is right or wrong.
• quite westernised concept- other countries focus on the good of the community (collectivist) not the individual (individualistic)
• criticised for being too idealistic
• humanism ignores social influences- people dont exist in isolation but within society
• limited evidence for hierarchy of needs
• assumes everyone has the ability to self actualise
• cannot explain abnormal psychology as it assumes humans have free will
