RESEARCH CHAPTER 1
1. Introduction to Epistemology
Epistemology is the study of different ways of knowing about the world. To progress, society must constantly generate new knowledge, which involves formulating questions and finding answers to better understand ourselves and our environment. While social scientists use systematic rational thought and observation, other methods also exist, with the scientific method offering clear advantages but requiring consideration for other adaptable methods due to social reality's complexity.
2. Non-Scientific Methods of Acquiring Knowledge
Several ways exist to gain knowledge that do not adhere to the scientific method:
2.1. Method of Authority
Description: Reliance on the knowledge and 'wisdom' of prominent individuals or caregivers recognized for their superior grasp of their environment. Their statements are often accepted without question.
Examples: Parents/caregivers for children, elderly in traditional societies, kings, heads of churches, technocrats, or specialists (e.g., cardiologists, computer experts).
Dangers: Individuals in authority may use strategies to preserve their position, such as masking ignorance with rituals, using specialized jargon, or emphasizing their unique position. This can hide superficiality, underlying ideology, and weaknesses in arguments.
2.2. Mystical Method
Description: A variation of the method of authority, where knowledge correctness is attributed to a supernatural source. 'Knowledge producers' are seen as authorities due to their ability to transmit truth imparted by supernatural forces.
Examples: Traditional healers and diviners in traditional African societies.
Credibility: Strongly related to the audience's level of education and general knowledge. Such methods lose influence when better, alternative explanations (e.g., scientific ones) emerge, as seen in the historical shift from believing the Earth is flat or the center of the solar system.
2.3. Intuitive Method
Description: Making judgments based on what 'feels' right, often without the ability to logically explain these feelings to others.
Example: A doctor arriving at a patient's diagnosis based on an intuitive feeling, potentially overriding laboratory test results.
Problem: Lack of transparency and communicability. Criteria used for conclusions are not clear, leading to differing conclusions by others and difficulty in replication.
2.4. Conventional Wisdom
Description: A variation of the intuitive method, reflecting 'common sense' understandings widely accepted as true.
Problem: Statements are often general, lack specific applicability details, and can be contradictory (e.g., 'opposites attract' vs. 'birds of a feather flock together'; 'out of sight, out of mind' vs. 'absence makes the heart grow fonder'). There is no systematic way to determine accuracy.
2.5. Rationalistic Method
Description: Knowledge acquired through human reason and logical thought, discovering laws purely through intellectual processes without relying on observation of reality or sensory input.
Example: Pure mathematics, where laws are discovered based on axioms.
Application: Successful in natural sciences but has made little progress in social sciences.
2.6. Empirical Method
Description: Knowledge is founded on facts observed in nature, emphasizing objectivity and limiting knowledge to what is perceivable by our senses.
Extreme Empiricism: Knowledge stops at observation; reasons for differences (e.g., why wood floats but iron sinks) are not considered if unobservable.
Problem: Disregards interpretations, speculation, and relationships between facts, potentially introducing subjectivity and distorting data. Critics argue that facts are meaningless without established relationships and explanations.
2.7. Inadequacy of Extreme Methods
Both the rationalistic and empirical methods, when taken to extremes, are inadequate on their own. The scientific method integrates their advantages.
3. The Scientific Method and its Properties
Science is defined as the building of knowledge through a particular methodology: the scientific method, or scientific research. It is a systematic investigation using specific principles. All sciences are united by this common method, not by their subject matter.
3.1. Process of Knowing: Synthesis of Rationalism and Empiricism
Quantitative Research: Aims to describe, explain, predict, and intervene.
Description: Accurate depiction of the object/relationship/situation using the empirical method (objective observation).
Explanation: Statement of relationships between facts, often expressed as a law, derived from rationalistic reasoning.
Prediction: The explanation should allow for foretelling future events under well-defined conditions.
Testing: Correctness of the explanation is tested against reality using the empirical approach (sensory perception).
Intelligent Intervention: Correct explanations enabling prediction should lead to changes that improve a situation.
Qualitative Research: Focuses on observation and recording events when little is known about a situation. A priori explanations are rare, and explanations are inferred at the end from collected data.
3.2. Properties of the Scientific Method (Assumptions)
Existence of natural and social laws: Science presumes order and regularity in natural and social events. Laws exist independently of the observer and describe how phenomena interact.
Laws can be discovered by human beings: Humans can discover the biological, psychological, sociological, economic, and political laws that govern them and their environment. These are observations of regularities, not legal statutes.
Natural phenomena have natural causes: No supernatural powers or unexplainable forces are needed to explain events.
Parsimony of ideas: Explanations should be based on as few assumptions as possible; simpler explanations are superior if equally valid.
New knowledge is accumulated gradually and sequentially: Advances in science occur through new instruments and approaches, often demonstrating limitations of previous knowledge.
Knowledge and truth are founded on evidence: Specific, commonly accepted rules define evidence, often derived from observations (sometimes with sophisticated instruments). Scientific claims require evidence; without it, they remain conjecture.
Scientific statements must be distinguished from common-sense statements: Common sense is often contradictory and lacks systematic investigation or specification of preconditions for validity.
Scientific observation is objective: Results are independent of a single observer, corresponding to descriptions made by anyone examining the same phenomenon. Measurable properties increase objectivity.
Scientific observation is systematic: All possibilities are considered one at a time, in a logical order (e.g., controlled experiments in chemistry, careful design in painkiller tests, structured educational interventions). If conditions are not fully known (especially in social sciences), probabilistic explanations are used, asserting an event will occur more often under certain conditions.
3.3. Properties of Scientific Research (Fundamental Characteristics)
Empirical: Aims to understand reality through observation at every step (collecting facts, testing explanations, assessing predictions/interventions). Reality is assumed to exist outside the observer. Quantitative methods aim for detachment; qualitative methods acknowledge and transparently account for biases.
Systematic and logical: Observations must be systematic, and a logical order must be followed (e.g., predictions follow description and explanation; questionnaire design follows variable analysis).
Replicable and transmittable: Due to objective observation and logical explanation, anyone in the same circumstances can observe the same event and arrive at the same explanation/prediction. Research steps and knowledge can be communicated (e.g., through reports/journals), fostering transparency, criticism, and skepticism.
Reductive: Reduces the complexity of reality by focusing on essential relationships and omitting non-essential details. Use with caution, as improper selection of variables to exclude can lead to significant bias.
Falsifiable: A scientific claim or theory must be stated in a way that allows it to be demonstrated as false through empirical scrutiny. It must make testable predictions about what should and should not happen. If forbidden events occur, the theory is untenable and must be rejected or modified. A useful theory forbids some events from occurring, making it robust against evidence.
