STS Notes: Science, Technology and Society
What is Science, Technology and Society?
- STS is the study of how social, political and cultural values affect scientific research and technological innovation, and how these in turn affect society, politics and culture.
- Science, Technology and Society are interlinked: science provides knowledge; technology applies that knowledge to solve problems; society shapes and is shaped by both.
- The course frame from the slides emphasizes understanding concepts, the scope of STS, and preparedness in studying STS.
The Essence of Science
- Science is not merely a list of equations or a catalog of facts; it is a way of thinking and a method to acquire knowledge.
- It seeks to unravel mysteries from the subatomic to the cosmic, and it is a dynamic process that evolves with accumulating knowledge.
- It encompasses many disciplines (physics, biology, psychology, astronomy, etc.).
- The essence lies in questions that drive exploration and inquiry as much as in answers.
- The systematic approach to modern science emerged during the Renaissance and Enlightenment, including the rise of the scientific method: observation, experimentation, hypothesis testing, and evidence-based conclusions.
- Science’s impact on society has grown exponentially; technological advancements have propelled science further in recent decades.
The Royal Society and Nullius in Verba
- The phrase on the slide: "Nullius in verba" translates to "on the word of no one" and is tied to the scientific method as a principle of evidence-based verification.
- The Royal Society motto embodies the commitment to verify statements by experiment and to withstand domination by authority when evidence contradicts claims.
- The idea: question authority and rely on empirical evidence.
Chapter 1: The Essence of Science (Key Points)
- Science is a method for acquiring knowledge about the natural world.
- It involves observation, experimentation, and exploration as means to knowledge.
- It is a dynamic and evolving process.
- Covers diverse disciplines and emphasizes asking questions as much as answering them.
Chapter 1: The Essence of Science – The Scientific Method
- The Scientific Method is a repeatable framework for investigating natural phenomena.
- Core steps often include: ask a question, do background research, construct a hypothesis, test with an experiment, analyze data, draw conclusions, report results.
- There are multiple versions of the method; all start from identifying a problem or question based on observations.
- The method emphasizes transparency and critique via peer review and publication to validate results.
- A common demonstration of scientific ethos is peer-review: anonymous critique by other scientists to weed out invalid methods or conclusions.
The Scientific Method: Process and Steps
- Basic sequence often taught:
- Ask a question
- Do background research
- Construct a hypothesis
- Test your hypothesis by doing an experiment
- Analyze your data and draw a conclusion
- Report your results (Was your hypothesis correct?)
- An additional emphasis: communicate findings through papers, presentations, or journals.
- A related model often taught:
1) Observe/Ask
2) Question
3) Research the problem
4) Develop hypothesis
5) Experimentation or hypothesis testing
6) Analyze data and draw a conclusion
7) Communicate findings/conclusions - Note: There is not a single universal sequence; variations exist, but all begin with identifying a problem through observation and questions.
- What is a hypothesis? An educated guess based on observations and knowledge of the topic.
- It is stated as a possible answer to a question.
- Common format: "If … , then … ." example: IF I water three plants with different sodas, THEN the plant that receives Sprite will grow the tallest.
Variables in Scientific Experiments
- A variable is anything that can change during an experiment.
- Independent Variable (IV): the factor that is deliberately changed/manipulated by the experimenter. IV
- Dependent Variable (DV): the factor that is measured/observed as a result of the manipulation. DV
- Controlled Variables (CV) or Constants: factors kept constant to ensure a fair test; everything except the IV should stay the same. CV
- Example: In a speed-reading study, the monetary incentive (Php 250) might be the IV; reading performance is the DV; a control group with no incentive is used to compare.
- Simple visualization:
- IV → DV (causal link)
- CVs kept constant
Independent, Dependent, and Controlled Variables (Definitions and Visuals)
- Independent Variable: the one thing you change in an experiment. IV
- Dependent Variable: what you measure in response to the IV. DV
- Controlled Variable: what you keep the same to ensure a fair test. CV
- Visualizing relation: IV (manipulated) causes DV (measured); CVs stay constant.
Inductive vs. Deductive Reasoning in Science
- Inductive Reasoning (bottom-up):
- Observation → Pattern → Tentative Hypothesis → Theory
- Deductive Reasoning (top-down):
- Theory → Hypothesis → Observation → Confirmation
- Both are essential in scientific inquiry: use inductive reasoning to formulate theories and deductive reasoning to test them.
Technology: Definition, Etymology, and Role
- Definition: Technology is the application of scientific knowledge, laws, and principles to produce services, materials, tools, and machines aimed at solving real-world problems.
- Etymology: Comes from the Greek word "techne" meaning art, skill, or cunning of hand; technology is the application (doing) of science.
- Technology represents the human attempt to change the world by creating products that make life easier.
- Technology is the use or application of scientific knowledge for practical purposes.
- A technological tool augments human senses or abilities and makes them more powerful (e.g., glasses or contact lenses to improve vision).
- Tools are characterized by their ability to extend human capabilities to achieve practical goals.
Society: Definition and Its Relation to STS
- Society comes from the Latin word "socius" meaning a friendly association with others.
- It is a large group of people who live together in an organized way, making decisions and sharing work.
- In STS, society is the arena where science and technology are created, implemented, and evaluated, and where ethical, cultural, and political considerations come into play.
How Science, Technology, and Society Interact
- Science explores knowledge for understanding the natural world.
- Technology uses scientific knowledge to solve problems and improve life; it informs and demands more from science.
- Society uses and benefits from technology and science; it also drives demand for new knowledge and devices.
- A common way to summarize interactions:
- Science explores for the purpose of KNOWING
- Technology explores for the purpose of making USEFUL things
- Society informs and demands more from both, seeking better living conditions
- The overarching dynamic is a cycle of seeking knowledge, applying it, and addressing societal needs and constraints.
The Nature of Science: Key Characteristics (Chapter 2)
- Science is a method for learning about the natural world.
- Knowledge is gained through observation, experimentation, and exploration.
- Attributes of science:
- Empirical: based on observation and experience. Empirical
- Objective: free from personal bias. Objective
- Non-dogmatic: open to revision. Nonext−dogmatic
- Self-correcting: willing to revise theories with new evidence. Selfext−correcting
- Systematic: follows a structured method. Systematic
- Transparent: methods and data are open for scrutiny. Transparent
- These attributes guide how science is conducted and evaluated.
The Process of Science: Basic vs Applied Science
- Basic Science: aims to gain knowledge for its own sake; understanding how the world works; often produces foundational theories (e.g., cell biology, DNA structure, inheritance, molecules).
- Applied Science: uses scientific knowledge to solve specific, practical problems and create technologies; examples include surgical techniques, windmills, solar panels, gene therapy.
The Scientific Method (A Working Overview)
- Steps often presented:
- Ask a question
- Do background research
- Construct a hypothesis
- Test your hypothesis by doing an experiment
- Analyze your data and draw a conclusion
- Report your results (Was your hypothesis correct?)
- A variant includes a separate step: communicate results and conclusions.
- Emphasizes transparency and critique through peer-review and publication.
The Scientific Method: A More Detailed View
- The method is a process used to find answers about the natural world.
- It is not a rigid formula; multiple versions exist with different numbers of steps, but all begin with problem identification via observation.
- Elements like observation, experimentation, data analysis, and communication are central across versions.
- A hypothesis is an educated guess based on observations and existing knowledge.
- It is stated as a possible answer to a question.
- Example format: IF [condition], THEN [expected outcome].
- Example: IF I water three plants with different sodas, THEN the plant that receives Sprite will grow the tallest.
The Role of Observation, Research, and Experimentation
- Observing or asking a question to state the problem.
- Researching the problem through reading, seeking advice, and making observations.
- Developing a hypothesis to predict outcomes.
- Planning and conducting experiments to test the hypothesis.
- Analyzing data and drawing conclusions.
- Communicating findings through reports or presentations.
Transparency and Peer Review in Scientific Work
- Scientific work is expected to be transparent and open to critique.
- New knowledge is vetted through peer-review and publication to ensure quality and reproducibility.
- Peer-review acts as a filter to remove invalid methods or conclusions.
Stepwise Example: Speed-Reading Study (Illustrative)
- Independent Variable (IV): Monetary incentive (e.g., Php 250) IV
- Dependent Variable (DV): Performance on reading test DV
- Controlled Variables (CV): Other factors kept constant (e.g., test duration, environment)
- Result: Compare performance with and without incentive to see if incentive affects outcomes.
Inductive vs Deductive Reasoning: A Quick recap
- Inductive Reasoning (bottom-up): Observation → Pattern → Tentative Hypothesis → Theory
- Deductive Reasoning (top-down): Theory → Hypothesis → Observation → Confirmation
- Use both: Inductive to generate theories; Deductive to test and verify them.
Summary: STS Relationships and Goals
- STS applies methods from history, philosophy, and sociology to study science and technology and to judge their value and place in society.
- STS emerged from questions about science-technology’s dynamic interactions with society.
- STS aims to bridge humanities and natural science to address moral, ethical, and existential dilemmas raised by science and technology.
- The overall goal is to understand how science, technology, and society influence each other and to guide responsible, ethical use of knowledge.
Interaction Models: How they influence each other in practice
- Science informs Technology (through discoveries and theories).
- Technology informs Society (through new tools, capabilities, and social changes).
- Society informs Science and Technology (through needs, ethics, policies, funding, and cultural values).
- The cycle: Science explores for knowledge → Technology uses knowledge to make life better → Society experiences impacts and demands more from science and tech.
Ethical, Philosophical, and Practical Implications (STS lens)
- Ethical questions about manipulation of nature, privacy, equity, and access to technology.
- Philosophical questions about the nature of knowledge, truth, and the role of human values in scientific practice.
- Practical implications include policy-making, regulation, education, and responsible innovation.
