Q

What are the characteristics of science?

A
  1. It is about the natural world and natural processes.
  2. Its aim is to explain how the world works (fact-finding practices).
  3. The explanations are empirically testable.
  4. The explanations can be proven wrong also even though they are thoroughly tested.

Q

Why is demarcation of science important?

A
  1. For many years, various research areas have exaggerated their scientific status and proclaimed to provide knowledge that is scientific even though it is not.
  2. Science is an important source of knowledge in our everyday life and it guides our decisions, e.g. when developing/prescribing medicine.

Q

What is pseudo-science?

A
  • Knowledge that claims to be scientific, but it isn’t.
  • Unwilling to recognise the data/observations that refute their explanations.
  • Its aim is to acquire the credibility of scientific knowledge.
  • It appears outwardly to be science, e.g. apply scientific methods, arranging conferences, journals and associations that share many of the superficial characteristics of science, but do not satisfy the quality criteria.

Q

Why is cognitive science a science?

A
  • Concerned with natural processes because it aims at finding explanations of the organisation of the mind and its mental processes.
  • Raises and investigates natural questions, e.g. how do we perceive objects in the environment?
  • Experimental approach (measuring, testing, neuroimaging, reaction times, eye gazes, digit span task)
  • Rediscovering itself as a field, acknowledging insufficient approaches, e.g. shift from behaviourism to cognitive revolution.

Q

Why is cognitive science not a science?

A
  • Investigates concepts that can be difficult to both define and measure. E.g. measuring memory, happiness, anxiety.
  • The variables are human beings = individual differences.
  • Replication crisis: unable to replicate results from fundamental studies.

Q

All pseudo-science is non-science. True or false?

Q

All non-science is pseudo-science. True or false?

A

False! Knowledge can be non-scientific without claiming to be scientific.

E.g. a cloud is non-science, but it is not pretending to be science, so it is not pseudoscience.

Q

What is epistemology?

A

The theory / study of human knowledge and how knowledge is acquired.
Considered a branch of philosophy.
Questions such as “What is knowledge?”, “How is knowledge acquired?”, “What do people know?”, “How do we know what we know?”

Q

What is ontology?

A

The branch of philosophy that studies the nature of human beings existence as individual, in society and in the universe.
It is also known as the theory of objects. It seeks to distinguish different types of objects (e.g. concrete/abstract, real/ideal, independent/dependent) and their relationships.

Q

What is “a priori knowledge”?

A
  • A priori knowledge is knowledge that can be justified without appeal to experience of the world.
  • Truth by definition, rather than truth by experience.
  • Universal and necessary knowledge, not by accident. E.g. mathematics.
  • Introduced by the German philosopher Immanuel Kant (1724-1804).

Q

According to A.A. Derksen, what are the three major reasons why demarcation is sometimes difficult?

A
  1. Science changes over time.
  2. Science is heterogenous (i.e. forskelligartet)
  3. Established science itself is not free of the defect characteristics of pseudoscience.

Q

How did logical positivists define the demarcation problem?

A

The problem of finding a criterion that distinguishes science from metaphysics.

17
Q

How would logical positivists solve the demarcation problem?

A

Distinguish meaningful statements (i.e. science) from non-sense statements (i.e. non-science).

Meaningful statements are either:

1) definitions that are necessarily true.
1) verifiable empirical statements, i.e. statements about the world that are meaningful if they live up to the verification criterion.

18
Q

What is the solution to the demarcation problem according to inductionism?

A

The verification principle!
Statements are scientific if they can be verified as true/false (‘conclusively decidable’).

19
Q

What is Popper’s solution to the demarcation problem?

A

Falsificationism!
A system is scientific if it is falsifiable, i.e. capable of being tested by experience and refuted/falsified by experience.

20
Q

According to Kuhn, when should the demarcation take place?

A

The demarcation should only take place in the period of normal science. It is only at this point, you are able to find the characteristics by which science can be distinguished from non-science.

21
Q

What is the difference between logical falsifiability and practical falsifiability?

A

Logical falsifiability only has to do with the logical structure of sentences and classes of sentences. A statements can be falsifiable although it is not in practice possible to falsify it.

Practical falsifiability has to do with falsifying a statement based on actual experience, measurement, observation of a phenomena.

22
Q

What is Kuhn’s demarcation criterion?

A

The capability of puzzle-solving.
When a result contradicts the existing paradigm, it becomes a puzzle for the researcher.

Example astronomy vs. astrology:
Astronomy has been a puzzle-solving activity and is therefore a science.
On the other hand, astrology do not have such puzzles in their discipline and astrology has therefore never been a science.

23
Q

What are the two forms of pseudo-science?

A
  1. Pseudo-theory promotion: Main goal is to promote a particular theory of their own, e.g. homeopathy, astrology, ancient astronaut theories.
  2. Science denialism: Driven by a desire to fight down some scientific theory of branch of science, e.g. holocaust denial, vaccination denialism, climate science denialism.
24
Q

What is homeopathy?

A
  • Disease caused by holistic changes in the body/mind.
  • Disease diagnosed by “homeopathic consultations” including symptom histories, psychological interviews, personality typing.
  • A medical system based on the belief that the body can cure itself.
  • Treatment: A ‘potentised’ compound. Potentiation means that there is no molecules of the compound left. The compound in larger amounts would cause the condition that is being treated.
25
Q

Who are some of the major historical figures in the tradition of a priori?

A

Plato, Descartes and Kant.
