Key Terms to Review (18)

Causal explanation: A causal explanation is a type of explanation that identifies the cause-and-effect relationships between events or phenomena. It seeks to clarify how one event leads to another, providing insight into the mechanisms and processes at play. This type of explanation is fundamental in understanding scientific inquiry, where establishing causal links is crucial for validating theories and testing hypotheses.
Constructivism: Constructivism is a philosophical viewpoint that posits knowledge and meaning are actively constructed by individuals rather than passively received from the environment. This perspective emphasizes the role of social processes, interactions, and cultural contexts in shaping understanding, suggesting that scientific knowledge is not an objective reflection of reality but is instead created through human activities and experiences.
Deductive vs. Inductive Reasoning: Deductive reasoning is a logical process where conclusions are drawn from general principles or premises, leading to a specific conclusion that must be true if the premises are true. In contrast, inductive reasoning involves making generalizations based on specific observations or evidence, leading to conclusions that may be probable but not guaranteed. Understanding these reasoning types is crucial for evaluating scientific practices and arguments, as they shape how hypotheses are formed, tested, and interpreted.
Demarcation Criteria: Demarcation criteria are the principles or standards used to distinguish between scientific and non-scientific claims or theories. These criteria help establish what qualifies as science, guiding the evaluation of methodologies, hypotheses, and the empirical basis of theories. Understanding these criteria is essential for assessing the validity and reliability of scientific practice, as well as distinguishing legitimate scientific inquiry from pseudoscience.
Empiricism: Empiricism is the philosophical standpoint that emphasizes the role of sensory experience in the formation of knowledge, asserting that knowledge is primarily derived from observation and experimentation. This approach connects closely with the practices of scientific inquiry, highlighting the importance of empirical evidence in validating theories and claims.
Falsifiability: Falsifiability is the principle that for a theory to be considered scientific, it must be able to be tested and potentially disproven by empirical evidence. This concept emphasizes the importance of observation and experimentation in science, ensuring that claims can be challenged and evaluated through rigorous methods.
Hypothetico-deductive method: The hypothetico-deductive method is a scientific approach that involves forming hypotheses and testing them through experiments and observations to draw conclusions. This method serves as a bridge between theoretical concepts and empirical validation, highlighting the dynamic interplay between philosophical inquiry and practical scientific investigation.
Karl Popper: Karl Popper was a 20th-century philosopher of science known for his contributions to the philosophy of science and the principle of falsifiability. His work challenged the traditional views of scientific method, advocating that scientific theories should be tested and potentially refuted rather than confirmed, emphasizing the dynamic nature of scientific inquiry.
Normal Science: Normal science refers to the regular, day-to-day research and activities conducted by scientists that operate within the established frameworks and theories of a particular scientific paradigm. It is characterized by the puzzle-solving activities that arise from shared assumptions and methodologies within a community, allowing scientists to refine and expand knowledge without challenging the foundational theories. This concept is central to understanding how science progresses gradually through established practices rather than through sudden upheavals.
Paradigm Shift: A paradigm shift refers to a fundamental change in the underlying assumptions and methodologies that define a scientific discipline. This concept is crucial for understanding how scientific fields evolve, as it signifies the transition from one framework of thought to another, often reshaping the way scientific inquiry is conducted and what is considered valid knowledge.
Predictive Power: Predictive power refers to the ability of a theory or model to accurately forecast outcomes based on prior observations and data. This concept is crucial because it highlights how effectively scientific theories can anticipate future events or results, thus providing a measure of their reliability and usefulness in both understanding and experimenting within the natural world. A high predictive power strengthens the credibility of scientific claims and informs the relationship between observation and experimentation.
Pseudoscience: Pseudoscience refers to beliefs, practices, or claims that are presented as scientific but lack the rigor, reliability, and empirical support that characterize genuine scientific endeavors. It often employs misleading methodologies and fails to adhere to the principles of scientific inquiry, leading to confusion between legitimate science and unproven ideas.
Rationalism: Rationalism is a philosophical viewpoint emphasizing reason as the primary source of knowledge and truth, suggesting that certain truths can be known through intellectual deduction rather than sensory experience. This perspective often contrasts with empiricism, as it posits that knowledge can be obtained independently of empirical evidence. Rationalism has significant implications for the relationship between philosophy and scientific practice, the demarcation problem regarding the distinction between science and non-science, and the historical development of philosophical thought within the science context.
Responsible research: Responsible research refers to the ethical and principled approach to conducting scientific inquiry, ensuring that research is conducted with integrity, transparency, and accountability. It emphasizes the importance of considering the societal impacts of research and adhering to ethical guidelines throughout the research process, which includes not only the pursuit of knowledge but also the moral implications of that knowledge in practice.
Scientific Integrity: Scientific integrity refers to the adherence to ethical principles and professional standards in the conduct of scientific research. It emphasizes honesty, transparency, and accountability in the generation and dissemination of scientific knowledge. Upholding scientific integrity is crucial for maintaining public trust in science and for ensuring that scientific findings are reliable and reproducible.
Scientific Realism: Scientific realism is the philosophical position that scientific theories aim to describe the world accurately, asserting that unobservable entities posited by these theories, such as electrons or black holes, truly exist. This perspective emphasizes that successful scientific explanations and predictions reflect an objective reality, connecting deeply with various aspects of scientific inquiry and understanding.
Theoretical vs. Observational: Theoretical refers to concepts, models, and frameworks developed through reasoning and speculation, while observational pertains to data and evidence gathered through direct experience or experimentation. Understanding the distinction between these two is crucial as it highlights the interplay between abstract reasoning and empirical investigation in science.
Thomas Kuhn: Thomas Kuhn was an influential philosopher of science known for his concept of 'paradigm shifts,' which describe fundamental changes in scientific thought and practice. His work highlights the importance of historical context in science, illustrating how scientific progress does not occur linearly but through revolutions that redefine the frameworks within which scientists operate.
