- First, we'll introduce the free will and determinism philosophy debate and provide an example of free will and determinism viewpoints.
- Next, we'll highlight the difference between determinism and free will in psychology.
- Then, we'll discuss how the problem of free will and determinism is reflected in psychological theories.
Finally, we'll evaluate both perspectives of psychology's free will and determinism debate.
Fig. 1: The free will vs determinism debate is concerned with whether we have free choice when it comes to our actions or whether our behaviour is determined by factors outside of our control.
What is the Free Will and Determinism Philosophy Debate?
The free will and determinism debate is a philosophical debate that addresses the extent to which factors outside our control influence our behaviour. There are two extreme sides to the debate: either people always have free choice, or they never can control their behaviour.
Just like there are extreme sides to the debate, so too are softer sides.
The argument for free will stems from the assumption that humans have complete autonomy to make their own decisions.
On the other hand, the argument for determinism stems from the assumption that human behaviour is merely a result of internal and external forces acting upon us. Cause and effect dictate behaviour, i.e., our actions directly result from our past experiences, environment, and genetic makeup. According to this perspective, free will is an illusion.
We can differentiate between hard and soft determinism.
- Hard determinism holds that our behaviour is solely the result of factors beyond our control.
- Soft determinism allows some degree of free will. It acknowledges that some behaviours are more constrained than others, i.e., the degree of free will may vary depending on the behaviour and the situation.
Since external factors constrain individuals, their behaviour is predictable but not inevitable because they also have some free will.
Proponents of free will argue that while external factors can influence our behaviour, humans ultimately decide how and whether to respond to these factors. Consider the following example of a free-will perspective of behaviour.
If a poor person steals because they have no money to feed themselves, the free will position argues that they still decided to steal despite the external factors (e.g., poverty). The decision to steal was their own.
This can be contrasted with a deterministic understanding of the same scenario.
Proponents of determinism would argue that being born into a low-income family is an environmental constraint. Stealing food is not a choice made out of a free will but out of the need created by poverty. Poverty is the cause, and stealing is the consequence.
By looking at this scenario again, through the lens of soft determinism, we can get a more nuanced understanding of behaviour.
Proponents of soft determinism would argue that being born into a low-income family is an environmental constraint, but choosing to steal is an example of free will. This is true when other options exist, such as borrowing money or receiving support from the government.
Difference Between Determinism and Free Will in Psychology
Psychologists use the scientific method to investigate the causes and correlates of human behaviour. Behind this approach lies an assumption that our behaviour is determined or constrained by external factors.
Psychological studies support the cause-and-effect argument of determinists because it explains behaviour and shows that we may be motivated by our biology, past experiences, or environment.
That is why many theories and approaches in psychology lie closer to the deterministic side of the spectrum.
The free will perspective in psychology would assume that, since individuals have complete free will to take any action they choose, it is also impossible to predict their behaviour accurately. While this approach doesn't align with the assumptions of scientific study, it has its benefits.
- It respects the dignity of humans, seeing them as active agents who can always turn their fate around and make wise choices whenever they have the option to do so.

Examples of Free Will and Determinism
Let's look at psychological theories and how they are placed on the free will and determinism spectrum.
Humanistic Approach
One approach in psychology based on the belief in free will is humanistic psychology, founded by figures like Maslow and Rogers. The humanistic approach places the responsibility for people's actions on them.
Free will is the foundation of this approach, as humanistic psychology sees people as having the potential to take control of their destiny to reach self-actualisation (one's full potential).
- The process of self-actualisation will often require people to reflect on and subsequently change their behaviours in a way that best aligns with their subjective values and needs. To make these changes, we need to have the ability to make free choices.
The humanistic approach in psychology supports the concept of free will in humans.
Biological Approach
The biological approach in psychology studies how biological predictors influence our behaviour or psychological outcomes.
Biological determinism is the view that our biology is responsible for our behaviour. Biology includes our DNA, brain processes, and hormones, among other things.
According to the biological approach, our internal biological processes can determine our behaviour. Our actions are not carried out because of free will but are triggered by our neurochemical activity, nervous system and hormones.
If anxiety runs in the family, a person may be predisposed to suffer from anxiety. In stressful situations, the predisposed person’s nervous system may trigger specific responses that indicate anxiety, such as nail biting, rocking, or hyperventilation.
The biological perspective is also reflected in John Bowlby's monotropic theory of attachment, which argues that humans are innately programmed to form an attachment to a primary caregiver.
He also noted that losing this attachment in the crucial first years of life can lead to long-term social, emotional, and cognitive damage and delinquent activity. On this basis, criminal activity can be predicted by past experiences such as maternal deprivation.
The biological approach in psychology supports biological determinism, which examines the influence of biology on behaviour.
Psychodynamic Approach
Sigmund Freud believed all behaviours had a ‘root’ motivation from the unconscious mind. Our choices are motivated by the unconscious rather than free will. This view is referred to as psychic determinism.
Psychic determinism views our behaviour as a result of preexisting mental or cognitive complexes; unconscious feelings such as fears, desires, and conflicts. These may have arisen during childhood or traumatic experiences.
Lorna experienced a car accident 7 years ago. Now she keeps postponing her driving lessons. At funfairs, she avoids bumper cars, saying she prefers rollercoasters. Psychic determinists would state that she is acting upon her unconscious fear of cars (specifically, the fear of crashing).
Freud’s theories about the Oedipus and Electra complexes in boys and girls explain how psychic determinism views behaviour. When boys and girls experience the Oedipus or Electra complex, they are likely to exhibit behaviours motivated by the desire to replace their parents of the same sex.
For example, boys may copy their father’s behaviour and act hostile towards him because of their unconscious desire to replace him.
The psychodynamic approach in psychology supports psychic determinism, which studies the influence of the unconscious on behaviour.
Learning Approach
Both behaviourism and Social Cognitive Theory can be used as examples of environmental determinism. Behaviourism focuses on the impact of learning from past experiences on our future behaviour, while the Social Cognitive Theory highlights the influence of the social environment we grow up in.
Environmental determinism views that external influences, such as past experiences, and the models in our lives and society, shape our behaviour. Our choices are the result of what we observe and what we are rewarded for during our upbringing.
If a child is punished for getting a bad mark by, for example, getting assigned extra homework, they are likely to be motivated to study more to avoid the punishment in the future.
Behaviourism would argue that learning, namely punishment and reward, influences a child’s future behaviour.
Several studies have demonstrated the influence of external factors on behaviour.
- Bandura’s Bobo doll study (1961) shows that children can exhibit physically and verbally aggressive behaviour when they see an adult doing the same thing. Bandura emphasises that behaviour emerges through observation and imitation.
- Skinner's animal studies have suggested that animal behaviour can be explained by conditioning and reinforcement.
The learning approach in psychology supports environmental determinism, examining the influence of external factors on behaviour.

Free Will and Determinism - Key takeaways
- The free will and determinism debate is a philosophical debate that addresses the extent to which factors outside our control influence our behaviour.
- The argument for free will stems from the assumption that humans have complete autonomy to make their own decisions.
- Determinism proposes that human behaviour is merely a result of internal and external forces acting upon us. There is hard and soft determinism and biological, environmental, and psychic determinism to consider.
- Humanistic psychology is founded on free will, while biological, psychodynamic and learning approaches can be considered deterministic.
- Each perspective within the debate has important implications for how we view morality, study behaviour and implement punishment as part of the justice system.

Frequently Asked Questions about Free Will and Determinism
What is free will and determinism?
The argument for free will stems from the assumption that humans have complete autonomy to make their own decisions. The argument for determinism stems from the assumption that human behaviour is merely a result of internal and external forces acting upon us.
Are determinism and free will reconcilable?
The two sides of the debate are very different; however, soft determinism appears to reconcile some assumptions behind both perspectives.
What is an example of determinism?
An example of determinism is the idea that our behaviour can be predicted by biological factors like our genes, brain structure, neurotransmitter activity or hormones.
What is free will in philosophy?
In philosophy, free will is the idea that humans can always make their own choices and that external factors do not constrain them.
What is the main difference between determinism and free will?
Determinists argue that we don't really have control over our behaviour because external factors constrain us. Proponents of free will argue that ultimately we have the autonomy to make our own decisions despite any constraints.
