The traditional view of science as objective and evidence-based

The traditional perspective on science presents it as a distinct method of understanding the world, rooted in objectivity and empirical evidence. This view contrasts science with other belief systems, such as religion, by highlighting its reliance on testable theories rather than unchallengeable doctrines.

Core principles of the traditional view of science

• Neutrality of scientists - Scientists are seen as impartial observers, uninfluenced by personal biases or preconceptions.
• Evidence-driven conclusions - Scientific theories and findings are grounded in observable data, prioritising facts over assumptions.
• Openness to revision - Science is considered an open system where incorrect ideas are discarded, and more accurate explanations are adopted based on new evidence.

Challenges to the objectivity of science

Despite the traditional view, some scholars have questioned whether science is as objective as claimed. These critiques suggest that scientists are influenced by existing theories and may not always approach evidence with complete neutrality.

Michael E. Lynch's study on scientific bias

• Method - In 1985, Lynch conducted research on scientists working with laboratory rats, observing their interactions and decision-making processes.
• Results - He found that scientists were often guided by pre-existing theories, more so than anticipated, when interpreting their findings.
• Conclusions - When unexpected results or anomalies arose, scientists frequently attributed them to errors in data or imagery rather than considering them as potential evidence for a new hypothesis.

Science as a belief system compared to religion

Some thinkers argue that science shares characteristics with belief systems like religion, challenging the notion that it is fundamentally different. This perspective frames science as a structured set of ideas that can resist change in ways similar to religious doctrines.

Polanyi's model of belief systems applied to science

• Circularity of beliefs - Scientific ideas often reinforce each other within the system, and challenges to one idea are defended by referencing others to maintain the overall framework.
• Explanations for contradictions - When evidence contradicts a scientific belief, explanations are provided to dismiss the discrepancy, much like anomalies observed in Lynch's study were explained away.
• Rejection of alternatives - Science can exhibit intolerance towards competing belief systems, such as a broad dismissal of religious perspectives, mirroring the exclusivity seen in other ideologies.

Postmodernist and ideological critiques

• Lyotard's view on metanarratives - Lyotard (1984) describes science as a metanarrative, claiming a monopoly on truth and offering explanations for all phenomena, akin to an overarching ideology.
• Marxist and feminist perspectives - Certain critics argue that scientific knowledge can be manipulated to reinforce capitalist and patriarchal structures, suggesting it serves specific societal interests rather than pure truth.

Sociology as a scientific discipline

Positivist thinkers advocate for sociology to be treated as a science, asserting that it can uncover objective truths about society through systematic methods. This approach aims to establish sociology as a field governed by empirical analysis and social laws.

Positivist approach to sociology

• Comte's belief in scientific sociology - Auguste Comte proposed that sociology involves collecting and classifying data about the social world to derive conclusions about the laws that govern human behaviour.
• Durkheim's multivariate analysis - Emile Durkheim used multivariate analysis to identify 'social facts' by isolating the effects of independent variables (causal factors) on a dependent variable (the outcome being studied).
  • For example, in studying educational attainment, independent variables might include parental income and school resources, while the dependent variable is student performance.
• Inductive method - Early positivists used an inductive approach, starting with data collection and analysis to form a hypothesis, which is then tested. If results are consistent across repeated studies, the hypothesis is accepted as a social fact.

Popper's deductive approach and falsification principle

Karl Popper challenged traditional scientific methods, proposing a different framework for how science should operate. His ideas focus on testing theories through attempts to disprove them, rather than seeking confirmation.

Key elements of Popper's scientific method

• Deductive approach - Unlike the inductive method, Popper's deductive approach begins with a theory or hypothesis, which may originate from inspiration or intuition, followed by targeted investigation to test it.
• Rejection of permanent laws - Popper (1959, 1963) argued that no social or scientific law is immutable; any theory can be disproved (falsified) at any time, regardless of how often it has been supported by past evidence.
• Example of falsification - Popper illustrated his point with the statement 'all swans are white,' which holds until a black swan is observed, demonstrating that theories must remain open to disproof.
• Aim of science - He suggested that the primary goal of science, including social science, should be to actively attempt to falsify theories, distinguishing it from belief systems like religion that resist such challenges.

The social context of scientific work

Scientific theories are not created in isolation but are influenced by the societal and cultural environment in which scientists operate. This perspective emphasises that science is partly a social construct shaped by external values.

Roger Gomm's analysis of science in context

• Method - Gomm (1982) examined the development of scientific theories, using Charles Darwin's theory of evolution as a case study.
• Results - He argued that Darwin's concepts of natural selection and 'survival of the fittest' were not fully supported by all available evidence, yet Darwin did not attempt to falsify aspects of his theory.
• Conclusions - Gomm suggested that Darwin's theories aligned with Victorian capitalist ideologies of individualism and free-market economics, influencing his reluctance to challenge his own ideas. This indicates that scientific work is shaped by the social context of its time.

Kuhn's concept of scientific paradigms

Thomas Kuhn introduced the idea that scientific progress is not always a linear accumulation of knowledge but is instead governed by overarching frameworks that shape research and interpretation at specific points in history.

Kuhn's paradigm theory

Kuhn (1962) described a paradigm as a set of widely accepted ideas, methods, and assumptions within which scientists work, defining what is considered valid or true at a given time.

Paradigm theory:

• Scientists typically seek evidence that supports the current paradigm, similar to Polanyi's concept of circularity in belief systems, rather than challenging the framework itself.
• When anomalies or contradictory evidence become too significant to ignore, a scientific revolution occurs, leading to a paradigm shift and the establishment of a new set of guiding principles for scientific enquiry.
• After a shift, a new 'normal science paradigm' is adopted, and the process of working within and eventually challenging this framework begins anew.
