2 – How to Build Knowledge Scientifically?
Why Should I Care?
How research is conducted can affect the results of a scientific project. It is important to understand the scientific method, since so much knowledge is derived from science. You have heard the saying, “The Devil is in the details.”
Definitions
Variable:
Any aspect or characteristic that varies from case to case, or over time.
Empirical data:
Data are sets of observations that were obtained from natural life. Empirical means that the data is not artificial or hypothetical.
Anecdotal data:
One or very few observations will be considered an anecdote, or anecdotal. Scientists won't base knowledge on small sample data sets.
Hypothesis:
A statement that focuses on the possible relationships between variables, expressed in a way that involves testing through observation.
Theory:
A logically coherent set of ideas that accounts for the empirical patterns discovered by empirical research.
Objects of Observation
Most variables measured in a social science research study would fall into the following categories. This is what scientists measure when they are
Personal Characteristic: height, skin color, eye color, shoe size, etc.
Socio-Demographic Characteristic: religion, gender, age, language, income, etc.
Opinion: political, hockey, moral, legal, cultural, artistic
Motivations: interests, goals, objectives, influences
Ideology: schools of thought, political parties, philosophies
Biases / Prejudice: culture, education, prior experience
Preferences: taste, needs, wants, cultural preferences
Personality: outgoing, resentful, loyal, personal values, upringing and grooming.
Personal History / Background: events, people, deaths, immigration
Family Dynamics: rank in the family, role, age, etc.
Cultural History: events, people, history class, family politics
Perception / Self-Perception: how you are perceived, how you perceive yourself
Aptitude /Ability: running, jumping, typing, reading, speaking, calculating, etc.
Behaviour: actions, verbal, non-verbal.
Intention: honesty, lying, mischief, morality.
Action: cowardice, bravery, brazenness, audacity, etc.
Level of Knowledge: test, quiz, recall, response time, memory.
History of Science
Science is a rather young development in human history. The scientific method, as applied in university research, really took off in the 18th century AD. This is not that long ago, if you consider that agriculture and cities appeared in about 8,000 years BCE.
However, there are debates as to which thinkers were the first scientists, such as Aristotle, who is credited with breakthrough studies in biology (Lo Presti, 2014). According to Harris (2020), "many experts recognize Ibn al-Haytham, who lived in present-day Iraq between 965 and 1039 C.E., as the first scientist. He invented the pinhole camera, discovered the laws of refraction and studied a number of natural phenomena, such as rainbows and eclipses."

During this period, the Arab world produced many innovations, such as the invention of algebra.
In terms of developing a very rigorous scientific method, many look to William Gilbert, a lesser-known British scientist credited with discoveries in magnetism. His work was extremely meticulous in his experiments, which set the bar for design and methodology in science.
The question has to do with their methods. Did they use hypothesis testing and observations, or did they use arguments? If they used arguments, like Thales in Ancient Greece, then they aren't considered true scientists.
Another point of contention is over the creation of the first university, which will accelerate the use of the scientific method. According to the British Broadcasting Corporation (BBC), the University of Al-Karaouine (also written as Al-Quaraouiyine and Al-Qarawiyyin) was founded in 859 AD and is "considered by UNESCO and the Guinness Book of World Records to be the oldest continually operating university in the world." The university was established at the very beginnings of Morocco’s oldest imperial city, Fez, which speaks to the utility of education and science to the development of cities (Griffiths & Buttery, 2018).
In Europe, the oldest, and still operating, university seems to be that of Bologna, Italy, which started as a law school in the year 1180 (Verger, 2003). This said, these were rocky times. During the medieval period, religious zealots burned many libraries on the continent. Thanks to Irish monks, the written works dating back to Ancient Greece and Rome had been transcribed and protected on the Éire Island, naturally isolated by the sea (Cahill, 1996).
Elements at the heart of science from its beginnings:
- Transparency
- In objective observation this is what I recorded
- In method this is how I recorded it
- Logic explanations are of reason
- Repeatability someone else could redo the whole thing and compare results
What is the Research Process?
There are 8 steps to the research process.
Step 1: Choose a topic 5 W
Step 2: Review the literature What do we know / ignore?
Step 3: Formulate the problem Question or Hypothesis
Step 4: Organize research design Pick and Create the instrument
Step 5: Gather data Observe and Record
Step 6: Analyze data Crunch the numbers, facts
Step 7: Interpret data Compare to flaws, caveats
Step 8: Communicate results Write article, conference
Formal theories are used to build steps 1, 2, 3 and 4.
The latter steps aim to verify the validity of the theories with empirical data.

How Research Begins
Research does not begin in the lab, or in a fieldwork activity. It might begin with a newspaper clipping, a conversation with a colleague, a movie, a book, an observation as a parent, a conversation with your grand-father, etc…
Personal experience – Nazi Germany, Racial Discrimination, Family Environment, etc. may lead some people who suffered these events to study these topics as researchers.
However, personal experience can also bias your approach. You may misinterpret the ideas and opinions of people that have another age, gender, ethnicity, mother tongue, income, social class, education, etc.
Values of Modern Research
Objectivity: gathering data honestly, even if discoveries contradict cherished personal beliefs
Empirical Verification: research does not depend on personal experience, intuition, faith in authority, or tradition to provide answers to their questions.
Cooperation: science builds on past research (for free) and lays the foundation of future research (for free). Scientists work together on science (for free).
Transparency of Method: communicate method and results clearly, honestly, and in enough detail that other researchers can fully understand how the research was carried out, and the data interpreted.
