Critical Thinking & Compliance Notes
What is critical thinking?
Definition used in the course: Critical thinking is the use of cognitive skills or strategies that increase the probability of a desirable outcome; it is purposeful, reasoned, and goal-directed thinking applied across contexts, not limited to philosophy.
Broad scope: Applies to solving problems, formulating inferences, calculating likelihoods, and making decisions; used in various domains (e.g., philosophy, planning a dinner party).
Disposition vs. skills: Requires both a disposition to engage in effortful thinking and formal knowledge of thinking strategies; not just innate ability.
Why does critical thinking matter?
Psychological evidence: Unreflective thinking yields systematic errors; people are credibly described as credulous and prone to relying on System 1 thinking.
System 1 vs System 2 (Kahneman-inspired view):
System 1: Fast, automatic, effortless; good in simple contexts but prone to systematic errors in complex contexts.
System 2: Slow, effortful, deliberate; improves accuracy but requires effort and training to use well.
Implication: Many errors arise because people don’t engage System 2 reasoning when it matters; developing a disposition to step back and reason is beneficial.
Goal: Become at least Level 1 critical thinkers (disposition to question and engage System 2) and aim for Level 2 (formal strategies) and beyond.
Levels of critical thinking
Level 1: Disposition to engage in effortful, directed reasoning; may rely on informal strategies; can solve simple problems but lacks formal strategies.
Level 2: Disposition plus basic formal strategies; knows how to assess whether an argument is good and how to reconstruct arguments; can apply discipline-specific critical thinking techniques.
Level 3: Highest level; not only skilled but also critically attuned to authority; questions reasons behind claims and evaluates sources; Socrates is presented as a model here.
Socrates and the Socratic ideal
Socrates as a model of Level 3 critical thinking: seeks reasons behind every claim offered by authorities; challenges prevailing views; does not uncritically defer to authority.
Deferral to authority matters: knowing when to defer and when to resist is essential; not all authorities are reliable, and context matters.
What is the point of deference to authority?
Authority can be reliable but should be evaluated: know whether an authority is credible, has expertise in the relevant field, and whether the consensus among experts supports the claim.
Distinction between epistemic authority and rhetorical appeal: it’s legitimate to rely on experts within their domain, but one should still critically examine the grounds for the claim.
Knowledge is social: we rely on others for information, so knowing when to defer and when to challenge is crucial for epistemic accuracy.
Argument reconstruction and evaluation (the core skill)
Why reconstruct arguments?
Stops you from accepting what you read at face value; helps you see structure and assess grounds.
Key components:
Conclusion: what the argument is trying to establish.
Premises: the supporting claims offered for the conclusion.
How to identify conclusions:
Ask: What is the argument trying to establish? What follows from the premises?
Look for indicator words: therefore, hence, thus, consequently, so, etc.
How to identify premises:
Look for claims offered in support of the conclusion.
Indicator words: since, given that, as shown by, because, for, etc.
Standard form representation:
Premises:
1) …
2) …
Supporting line
Conclusion: …
Acceptability of premises vs. support for the conclusion:
Two questions:
Are the premises rationally acceptable?
Do the premises, taken together, provide adequate support for the conclusion?
Cogent vs not cogent:
A cogent argument has acceptable premises and premises that provide adequate non-deductive support for the conclusion (or deductive support if applicable).
Premise acceptability criteria (summary):
Cogent sub-argument for the premise; known a priori; common knowledge; reliable testimony; proper authority; etc. (with caveats about circularity, usefulness, and context).
Deductive vs non-deductive support
Deductive support (gold standard):
If the premises are true, the conclusion must be true.
Example: All men are mortal. Socrates is a man. Therefore, Socrates is mortal.
Formally: If P1, P2, …, Pn then C; with truth of P1..Pn guarantees C.
Non-deductive support: premises aim to provide strong but not guaranteed support for the conclusion.
Inductive: supports typically what is the case (probabilistic).
Abductive: follows from the best explanation of the observed facts.
Even with true premises, the conclusion may be false; the strength comes from how well the premises support the conclusion.
Examples in class:
John’s car in driveway, lights on; John is probably home (non-deductive support; best explanation offered by premises is that John is home).
Variants with missing premises illustrate how the best explanation or additional premises strengthen the case.
Concrete and practical examples used in the session
The bat and ball problem (System 1 vs System 2):
Problem: A bat and a ball cost $1.10 together; the bat costs $1 more than the ball. How much does the ball cost?
Common (System 1) answer: 10 cents.
Correct algebra (System 2):
Let ball price be x, bat price is x+1.00, total: x + (x+1.00) = 1.10
Solve: 2x + 1.00 = 1.10 \ 2x = 0.10 \ x = 0.05
Ball cost: 0.05; Bat cost: 1.05; Total: 1.10.
Lesson: System 1 yields an intuitive but incorrect answer; algebraic reasoning (System 2) yields the correct result.
Level distinctions in practice:
Level 1: Students can identify the basic problem and use informal strategies.
Level 2: Students learn formal strategies for reasoning and argument evaluation.
Level 3: Ability to question authority and to assess the reliability of authorities with a robust framework.
Formal training in critical thinking strategies
Why formal strategies matter:
They help you check if you are relying on automatic heuristics and give you tools for structured evaluation.
How philosophy and the arts/humanities influence thinking:
Emphasis on learning to identify good vs. bad arguments and to evaluate reasons.
Sciences emphasize formal and specific strategies for evaluating claims.
Practical aim:
Develop fluency in identifying premises, conclusions, and the type of support offered; reconstruct arguments; and assess their cogency.
Why study critical thinking in society
Benefits include resisting deception and manipulation; not being duped by misinformation, government missteps, or conspiracies.
Socratic virtue: pursue reasons for beliefs, not mere acceptance of claims from authorities; yet do not swing to wholesale distrust of all authorities.
Balancing act: critical thinking should avoid both uncritical deference and ungrounded conspiracy thinking.
Epistemic authorities and evaluating sources
Socratic stance: defer to authorities only when they can give reasons that you can evaluate; seek the reasons behind claims.
When to defer and when to question: depends on reliability, expertise, and consensus within the relevant field.
Common pitfalls:
Appealing to authority as a substitute for reasoning.
Over-skepticism that erodes credible knowledge by rejecting legitimate expertise.
A practical strategy for evaluating authorities (typical framework):
Is X reliable and credible in this context? Any biases or conflicts of interest?
Does the claim fall within X’s area of expertise or specialization (K)?
Do experts in K largely agree about P? Is X an outlier?
If there is consensus, treat P accordingly; if there is disagreement, check further.
If X is not an expert in the relevant field, be cautious.
Fallacy to avoid: appealing to authority without meeting these criteria (appeal to authority fallacy).
Real-world concerns: beware conspiratorial thinking that undermines trust in legitimate institutions; seek a balanced approach.
Conspiracy theories: what goes wrong and why trust matters
Conspiracy theories often claim hidden plots and imply that evidence you would expect to see is itself evidence for the conspiracy.
Typical errors:
If new evidence appears, the conspiracy theorist rejects it as part of the cover-up rather than updating beliefs.
A belief in a broad, all-encompassing conspiracy that includes trusted institutions (media, experts).
Consequences: loss of trust in credible sources can lead to isolation from the shared search for truth and civil discourse.
The value of trust: society benefits from credible epistemic sources and shared methods of inquiry; critical thinking helps maintain a healthy balance.
Strategies and exercises in the course
Argument identification, reconstruction, and evaluation
Stop, identify premises and conclusion, and reconstruct in standard form.
Evaluate the acceptability of premises and whether they provide adequate support for the conclusion.
Distinguish deductive vs non-deductive support; understand how to test for cogency.
Practice activity (encouraged collaboration): work through five arguments on a handout; reconstruct, assess acceptability, identify type of support, and judge cogency.
Discussion of epistemic authorities and conspiracy theories as a capstone for evaluating sources and balancing skepticism with trust.
Practical implications and takeaways
Half the work of thinking critically happens simply by pausing and engaging System 2 reasoning; the other half involves learning and applying formal strategies.
Being a Level 2 thinker requires both disposition and formal training; Level 3 requires careful evaluation of authorities and sources.
Critical thinking is not just for philosophy; it improves performance across disciplines and everyday decision-making.
Always consider whether you should defer to credible authorities, and what the grounds for that deferral are.
Summary references to core ideas and terms
Critical thinking: purposeful, reasoned, goal-directed thinking applied across contexts.
System 1 vs System 2: fast/automatic vs slow/deliberate reasoning.
Level 1, 2, 3 critical thinkers: increasing depth of thinking strategies and attitude toward authority.
Argument reconstruction: identify premises, conclusion, and represent in standard form.
Premises: claims offered in support of the conclusion; conclude rational acceptability and adequate support.
Deductive vs non-deductive: deductive guarantees; non-deductive provides strong but non-necessary support; inductive vs abductive distinctions.
Epistemic authorities: evaluating reliability, expertise, consensus, and potential biases.
Conspiracy theories: risks of distrust without justification; maintaining trust while being critical.
Compliance unit: student visa information (ECOE, visa, and related requirements)
Key terms:
ECOE (Electronic Confirmation of Enrollment): Issued by the university for student visa purposes.
Student visa: Granted by the Department of Home Affairs to allow onshore study; has strict conditions and duration.
Weibo: The Australian Government platform (not a social media site) for visa status checks; students should verify visa details there.
Important relationships:
ECOE does not equal student visa; visa status can differ from COE and ECOE.
Visa status can be checked via the Weibo platform; changes in visa status should be reported and managed.
Key requirements for student visa holders:
Maintain a valid ECOE, comply with visa conditions, complete on time, and apply for a new visa before expiry.
Failure to comply can lead to visa cancellation and disruption of study plans.
Financial and risk considerations:
Visa application fees have risen: last year 1600; this year 2000; potential extension costs around 700; total near 2700 (without living costs).
Completing on time is crucial to avoid extensions and additional costs.
Full-time enrollment requirements (Condition A20): three-layer structure:
Enroll full-time in an approved course (per teaching period); maintain the same AQF level; monitor attendance and course progress.
Examples: switching from an honours degree to a lower AQF level (e.g., graduate certificate) may require a new student visa.
If unable to study full-time, students can apply for a reduced study load or suspension under documented compassionate or compelling reasons.
Full-time definition and credit points:
Two teaching periods per year; minimum 24 credit points per period to be considered full-time (18 in green sessions + 6 in orange sessions, or a total of 24 per period).
Reduced load can affect current visa duration and may require a new student visa to complete the program.
Work restrictions (Condition 2):
Students may work up to 48 hours per fortnight when enrolled; some intensive sessions may count as study and restrict work hours.
Certain work (e.g., Uber driving) has been scrutinized; DHS can audit and penalize for working over the limit.
Overseas Student Health Cover (OSHC):
Mandatory for student visa holders; ensures access to medical services; not available through Medicare for international students.
Address and identity requirements:
Must inform the university of current address within 7 days; enables university to contact and assist if attendance issues arise.
Other administrative notes:
If visa status changes (e.g., to permanent residency or to another visa type), update the Department of Home Affairs; still subject to student visa conditions if staying on a student visa.
When applying for COE and visa renewals, provide updated information; request COE no earlier than 3 months before visa end date to avoid errors.
Onshore visa applications are preferred; if offshore, bridging visas may not be granted, potentially interrupting study.
Use university email for official communications; ensure USI (Unique Student Identifier) is obtained for graduation eligibility.
Read compliance newsletters and monitor important dates (census dates, deadlines) to avoid penalties.
Final practical advice:
Seek early help from faculty for course planning and degree checks to avoid delays and extra costs.
Maintain honest and timely communication with DHA case officers and university compliance staff; provide requested documents promptly to avoid refusals or delays.
Treat information from compliance units as a reliable source of guidance for visa-related issues.
