Ever wondered if science is really as objective as it... Show more







Think about how you view the world - those basic ideas about fairness, success, and how society works are your ideology. Political viewpoints like socialism or conservatism are ideologies too, but some thinkers argue they can distort reality.
Karl Popper had a controversial take: he said ideology is any "closed system of thought" that refuses to consider opposing evidence. By this definition, even some religions, Marxism, and feminism could be ideologies because they reject challenges to their core beliefs.
Meanwhile, science tries to be different by using empiricism (learning through observation) and objectivity (removing personal bias). Scientists test theories repeatedly through experiments, building knowledge over time - what we call cumulative learning.
Key Insight: Science has massive power to change our world - from curing diseases to creating weapons of mass destruction. This shows why understanding how knowledge is created matters so much.

Here's what makes science special, according to Popper: it's genuinely open to criticism. Real scientists actually try to falsify (disprove) existing theories rather than just prove themselves right. This keeps them honest and objective.
Newton captured this perfectly when he said he "stood on the shoulders of giants" - scientific knowledge builds on previous discoveries. Each generation improves on the last, which is why we can never accept any scientific explanation as completely true forever.
Merton's CUDOS method explains how science works as a community: Communism (sharing knowledge), Universalism (judging ideas objectively), Disinterestedness (seeking truth for its own sake), and Organised Scepticism (questioning everything).
However, Popper rejected sociology as a "pseudo-science" because concepts like "false class consciousness" are too abstract to measure directly. This criticism still shapes debates about whether sociology can ever be truly scientific.
Remember: Stephen Hawking said all his discoveries about the universe are "provisional" - meaning other scientists will improve on them later.

Unlike science, closed belief systems like religion claim to have perfect, unchangeable truth. They use clever tactics to protect themselves from contradictory evidence, as Polanyi identified.
Take the Azande people and their witchcraft beliefs. When their poison oracle (benge) fails to work properly, they don't question the system - they just blame incorrect usage. This shows the three defence mechanisms: circularity (explaining ideas using other ideas from the same system), subsidiary explanations (making excuses when things go wrong), and denial of legitimacy (refusing to consider alternatives).
Deductive research starts with a theory and tests it (like studying whether racial bias affects university admissions). Inductive research starts with data and builds theories from patterns (like Durkheim's study of suicide rates among different religious groups).
Even science isn't immune to closed thinking. When Dr. Velikovsky proposed alternative theories about Earth's origins in 1950, the scientific community boycotted his work without even reading it properly.
Think About It: The Azande understand HOW events happen (snake bite from stepping on a snake) but use witchcraft to explain WHY they happen at that specific moment.

Thomas Kuhn revolutionised how we think about science by showing it's not just steady progress - it goes through dramatic paradigm shifts. Most of the time, scientists work within established assumptions, doing "normal science" .
But occasionally, so much contradictory evidence builds up that the entire paradigm collapses and gets replaced. Think about how we went from believing the Earth was flat to accepting it's round - that's a paradigm shift.
Kuhn identified three stages: pre-science (no dominant theory), normal science (everyone follows the established paradigm), and revolutionary science (the paradigm gets challenged). Sociology might still be in the pre-science stage since we have loads of competing theories.
Knorr-Cetina argues science and sociology are fundamentally different anyway. Science studies matter without consciousness , while sociology studies humans who actively make meaning from their experiences.
Reality Check: Scientists who challenge existing paradigms often get ignored or ridiculed, while those who make discoveries within the accepted framework get rewarded and promoted.

Marxists see ideology as the ruling class's tool for maintaining power. They spread ideas like "inequality is natural" or "poor people are just lazy" to create false consciousness among workers. This stops the working class from realising they're being exploited.
Gramsci called this ideological dominance hegemony. However, he believed workers have "dual consciousness" - they're influenced by ruling class ideas but also develop their own understanding through experiencing exploitation. This gives hope for eventual revolution.
Karl Mannheim took a different approach, arguing that all belief systems are partial viewpoints. Ideological thought supports the privileged and maintains the status quo, while utopian thought comes from the underprivileged and pushes for change.
Feminists focus on how patriarchal ideology maintains gender inequality. Pauline Marks showed how 19th-century science was used to exclude women from education, with male doctors claiming it would create "puny and unfeminine females." Many religions also promoted ideas about women being inferior or "unclean."
Critical Point: Some critics argue it's not ideology but economic factors (like fear of unemployment) that really keep workers from rebelling against capitalism.

Both science and religion are belief systems that try to explain how the world works, but they do it in very different ways. Religion might explain illness as "God's will," while science offers medical explanations based on evidence.
One major similarity is funding dependence. Science relies heavily on corporate sponsors, which can create bias when researchers need specific results to keep their funding. Religion similarly depends on donations from believers, using this money to build communities through activities like youth clubs.
Both systems also operate within paradigms - sets of assumptions that new ideas must fit into to be accepted. The scientific community might reject "radical science" theories that don't fit their worldview, just as religious institutions might dismiss fossil evidence because it contradicts creation stories.
This means neither system is as purely objective as it claims to be. Both require new theories and members to conform to existing frameworks, which can limit genuine innovation and critical thinking.
Essay Tip: When comparing belief systems, always consider how power structures and funding influence what gets accepted as "truth" in each system.
