H567/02 Section B - Free will, determinism, reductionism and holism

Choice and causes

Hard determinism treats behaviour as fully determined, leaving no genuinely free choice. Soft determinism recognises causal influences while allowing meaningful choice when a person can act according to their reasons without coercion. A strong free-will position emphasises the person's ability to choose among alternatives, rather than merely execute a caused response.

Biological determinism emphasises inherited or physiological causes; environmental determinism emphasises learned associations, consequences or situational pressures. Psychic determinism in Freud's account emphasises unconscious motives and earlier conflicts. These are different proposed causes, not interchangeable labels.

Prediction is relevant to determinism but not conclusive. A statistical tendency can reflect causal influences without making every person's action inevitable. Equally, an unexpected action or refusal does not demonstrate that it was uncaused: beliefs, past experiences or other influences may explain it. A person's feeling of choosing provides evidence about experience, but does not by itself settle the origins of that choice.

Applications reflect these positions. A deterministic explanation of repeated misconduct encourages investigation of modifiable triggers and learning history. A free-will account supports opportunities for reflection and personal responsibility. A soft-determinist application could offer genuine choices while reducing coercion and recognising constraints. These are explanatory implications, not legal conclusions about an individual.

Evidence, pressure and agency

Milgram (1963) found that many men continued administering apparent shocks when a credible experimenter told them to proceed. Distress alongside obedience suggests that authority can constrain behaviour despite personal discomfort. However, some stopped. The baseline study did not manipulate a comparison condition, and refusal may itself have causes. Thus it supports strong social influence without proving hard determinism.

In Bocchiaro et al. (2012), students were asked to write a positive recruitment statement for a supposedly harmful sensory-deprivation study while omitting its negative effects. They could refuse or report concerns using a research-committee form. Most obeyed, while others disobeyed or reported the request. The gap between predicted and actual behaviour challenges reliance on what people say they would freely choose. Refusal and reporting show available alternatives, but the study did not isolate a metaphysically free decision from personal and situational causes. A standardised authority scenario is not an experiment manipulating a causal IV merely because the original title uses “experimental”. OCR guide, pp11–15.

Casey et al. (2011) linked earlier delay ability to adult responses and brain activation during an emotional inhibition task. That makes biological influences relevant to self-control. Yet selective performance differences in tempting contexts and a non-randomised delay grouping do not show that every action is fixed by the brain, or that a person cannot improve. Original study.

A workplace could therefore combine independent confidential reporting with practice in challenging instructions. This changes the pressures under which choices are made instead of assuming either complete personal freedom or unavoidable obedience. Evaluating the proposal requires checking whether people actually use the route safely, not simply whether it exists.

Reductionism, holism and levels of explanation

Biological reductionism might explain a behaviour mainly through neural circuits. Environmental reductionism might explain it mainly through reinforcement. A narrower task may also reduce a broad construct, such as intelligence or self-control, to one measurement. The criticism concerns whether important explanatory information is lost, not merely whether a study used numbers.

Holism is more than listing many factors. A holistic explanation should specify how personal history, biological capacities and relationships combine, so that the whole pattern is understood. A multi-level explanation can retain useful evidence about parts while considering their interaction. Studying a neural mechanism need not mean claiming that it is the only cause.
