Critical Thinking - An Upgrade For Your Mind

Identify and break down arguments by distinguishing premises from conclusions, recognizing giveaway words like therefore, and understanding premises support the conclusion, and learn three key ways an argument can fail.

Distinguish arguments from explanations and disagreements by identifying premises and a conclusion that support a claim; learn to avoid confusing explanations or mere disputes.

Identify what makes an argument strong or weak by examining premises and conclusion, false premises, faulty logic, and fallacies like hasty generalization and question begging.

Explore how the slippery slope fallacy claims one step leads inevitably to extreme outcomes in medical, legal, and safety debates. If inevitability isn't shown, the argument remains fallacious.

False dilemmas present two options to manipulate decisions, often hiding a viable third path, as shown by tv-store, defense-budget, and 'you're with us or against us' examples.

The post hoc fallacy traps reasoning by assuming causation from sequence after this, therefore because of this; evaluate coincidental events and seek alternative or common causes.

Identify and avoid the straw man fallacy by recognizing when others distort or quote out of context, then attack the actual argument rather than a weakened version.

Explore how defeaters undermine our beliefs by challenging initial grounds, distinguishing undercutting defeaters from rebutting defeaters. Use examples like water distortion and scarecrows to see when to stop believing.

Examine when beliefs based on appearance or testimony are reasonable, and why some beliefs must be supported by argument; identify positive grounds for doubting appearances.

Explore how the power of suggestion shapes perception, memory, and behavior through the placebo effect. See how expectations influence pain, energy, and even memory and perception in everyday examples.

Examine the gambler's fallacy, where people overlook independence in random events like Monte Carlo roulette or coin flips, assuming next outcomes change; each trial stays 50/50, with implications for investing.

Examine confirmation bias by counting both hits and misses and looking for evidence against the hypothesis, avoiding cherry picking that misleads belief about Sarah's shooting ability.

Examine how subtle question wording after an event shapes memory, triggering the misinformation effect and altering eyewitness speed estimates and recall of details.

Explore how the Barnum effect makes horoscopes seem accurate by applying a Petiot's chart case study to reveal cognitive bias and illusory insight.

Explore six debiasing strategies—bias awareness, red teams, anonymous voting, premortems, defend judgment, and psychological safety—to counter cognitive biases like anchoring and confirmation bias.

Distinguish deductive from inductive reasoning by showing how premises support or guarantee conclusions, compare validity and cogency, and explore enumerative induction and the argument to the best explanation.

Explore how inductive and deductive reasoning drive scientific claims, contrasting guarantee versus support, and learn how scientists test, falsify, and combine both approaches to explain observed phenomena.

Explore what counts as evidence and how empirical data, strong or weak, shifts our probability of truth, while examining cognitive dissonance and real-world examples like rain, swans, and aliens.

Explore why bloodletting persisted for two thousand years, tied to barbers and the red and white striped pole, despite weak evidence and the need to test benefits.

Explore how controlled, double-blind trials guard against the placebo effect in medical testing, illustrated by bloodletting studies and Clever Hans, and discuss the experimenter effect and belief perseverance.

Explore cognitive dissonance as the discomfort from heavily invested beliefs when they're contradicted, illustrated by Festinger's UFO cult prophecy and the urge to explain away evidence.

Explore how people explain away evidence to defend strong beliefs, recognize cognitive dissonance, and avoid intellectual black holes that trap reasoning.

Develop independent critical thinkers who resist false ideologies, question rather than conform, and apply reasoning to moral choices, guided by non-authoritarian upbringings and proactive discussion.
