Free Will and Determinism

  • Free will is the idea that we are self-determining
    • Humans are free to choose thoughts/actions
    • Biological/environmental influences on behaviour but we can reject them
    • Behaviour has no cause/is unpredictable
    • View of the humanistic approach
  • Determinism: behaviour is shaped/controlled by internal and external forces
    • Hard determinism
      • Behaviour is completely out of our control
      • All human behaviour has a cause that should be possible to identify
      • All behaviour is predictable
      • Compatible with the aims of science
    • Soft determinism
      • All behaviour has a cause
      • People have conscious mental control over behaviour (James 1890)
      • Behaviour is predictable to an extent
      • Some free will to make choices
  • Biological determinism
    • The biological approach
    • Control from internal biological factors
      • Physiological processes are not under conscious control
        • g. influence of the ANS on stress/anxiety
      • Genetic factors may determine many behaviours/characteristics
        • g. mental disorders
      • Hormones may determine behaviour
        • g. role of testosterone in aggressive behaviour
  • Environmental determinism
    • Popularised by behaviourist approach
    • Skinner: all behaviour is the result of conditioning
    • Experience of choice is just the total sum of reinforcement contingencies that have acted upon us during our lives
    • Illusion of free will but behaviour is shaped by environmental events/agents of socialisation
      • g. parents, teachers, institutions
  • Psychic determinism
    • Freud: emphasis on biological drives/instincts underpinning psychological responses
    • Determined/directed by unconscious conflicts repressed in childhood
      • g. even a ‘slip of the tongue’ can be determined by the unconscious
  • Science seeks causal explanations
    • Basic principle: every event has a cause that can explained with general laws
      • Allows scientists to predict/control events
    • One thing is determined by another
    • Lab experiments
      • Researchers remove extraneous variables to demonstrate a causal effect
  • Determinism: consistent with aims of science
    • Human behaviour is orderly/obeys laws
      • Greater scientific credibility
    • Prediction/control of human behaviour has led to the development of treatments/therapies
      • g. psychoactive drugs to manage schizophrenia
    • Experience of schizophrenia suggests some behaviours are determined
      • Loss of control over thoughts/behaviour
      • No one chooses to have schizophrenia
  • Hard determinism: not consistent with legal system
    • Offenders held morally accountable for their actions
    • Only instructed to act with leniency in extreme circumstances
      • g. Law of Diminished Responsibility in cases of mental illness
    • Determinism is not falsifiable
      • Based on the idea that causes of behaviour will always exist, even though they may not have been found yet
      • Impossible to disprove
      • Not as scientific as it first appears
  • Free will: we make choices in everyday life
    • Everyday experience gives us the impression that we are constantly making choices
    • Gives free will face validity
      • It makes logical sense
    • Even if we do not have free will, thinking we do might have a positive impact on the mind/behaviour
      • g. Roberts et al (2000)
        • Adolescents with strong beliefs in in fatalism were more at risk from depression
