Bullshit

Bullshit is language, data, or other forms of presentation intended to distract, confuse, or mislead an audience — characterized by a blatant disregard for truth rather than an attempt to assert a specific falsehood. Unlike lying (which cares about truth enough to contradict it), bullshit is indifferent to the truth entirely. It aims to persuade, impress, overwhelm, or intimidate, not to accurately represent the world.

How It Appears Per Course

PHIL 252

Introduced in Unit 1 as the central adversary of critical thinking. Expanded in Unit 2 with a full taxonomy. The course treats bullshit detection as a practical skill requiring specific methods — argument analysis, cogency evaluation, and questioning the source.

Bullshit requires a Theory of Mind (understanding that others have perspectives) because it is designed to manipulate what others believe. It also obeys Brandolini’s Principle: it takes far more energy to refute bullshit than to produce it, which explains why misinformation spreads faster than corrections.

Taxonomy of Bullshit and Misinformation

TermDefinition
Bullshit (general)Claims with blatant disregard for truth, designed to distract/overwhelm/impress
Nonsense BullshitMeaningless academic/technical language “so cloaked in rhetoric that no one can critique it”
Persuasive BullshitConveys an exaggerated sense of competence or authority
Evasive BullshitAvoids directly answering a question the speaker prefers not to address
MisinformationFalse claims not deliberately designed to deceive
DisinformationFalsehoods spread deliberately, often through trusted networks
Firehose StrategyFlooding channels with contradictory claims to exhaust fact-checking
Community EpistemologyTruth determined by group identity, not evidence (related to confirmation bias)
Black BoxScientific claims too complex for non-experts to evaluate — exploited by bad-faith actors

Language Manipulation Tactics (Unit 1)

  • Implicature: the gap between literal meaning and what a statement is used to mean
  • Paltering: misleading without technically lying
  • Weasel Wording: exploiting implicature to avoid responsibility (e.g., “job creators”)

Social Signalling and Bullshit

Research by Judith Donath: news on social media is often shared not to inform, but as a marker of identity — signalling group membership. In this case, the person sharing is indifferent to the truth of the content; its value is social, not epistemic.

Cross-Course Connections

CriticalThinking — critical thinking is the antidote
Argument — formalizing reasoning into public arguments is how we resist bullshit
Bias — community epistemology and confirmation bias enable bullshit to spread
DataVisualization — new-school bullshit uses data graphics to mislead

Key Points for Exam/Study

  • Bullshit ≠ lying: the liar cares about truth (to contradict it); the bullshitter is indifferent to truth
  • Brandolini’s Principle explains the asymmetric spread of misinformation
  • Two “flavours”: Old-School (fancy empty language) and New-School (misleading data)
  • Firehose Strategy: not trying to convince of a specific falsehood, but to create confusion about what is true
  • Three questions to always ask: Who is telling me this? How do they know? What’s in it for them?

Spotting Bullshit: Six Tools (Bergstrom & West, Ch. 10)

Six practical tools from Calling Bullshit (2021) for identifying misleading claims in media and everyday life:

#ToolThe Rule
1Question the sourceWho is telling me this? How do they know? What are they trying to sell?
2Beware unfair comparisonsComparisons are only valid if the entities being compared are directly comparable
3Too good/bad to be true? Dig to the sourceSocial media amplifies extreme, shocking claims — the most viral posts are often the most distorted
4Think in orders of magnitude (Fermi estimation)Back-of-envelope approximations to check plausibility; being off by 50% still keeps you within tenfold of the truth
5Avoid confirmation biasThe tendency to notice, believe, and share information consistent with preexisting beliefs — “the chief source of bullshit you have to contend with is yourself” (Neil Postman)
6Consider multiple hypothesesJust because someone has an explanation for a pattern doesn’t mean it’s the explanation

Illusory truth effect: The more often you see something, the more likely you are to believe it. Repeated exposure creates a false sense of credibility.

Online bullshit checklist:

  • Corroborate and triangulate (check multiple independent sources)
  • Dig back to the origin story; read the full article, not just the headline
  • Use reverse image lookup (TinEye, Google Images)
  • Use fact-checking sites: Snopes.com, PolitiFact.com, FactCheck.org
  • Be aware of deepfakes and synthetic media
  • “Think more, share less”

Refuting Bullshit (Bergstrom & West, Ch. 11)

ConceptDefinitionExample
Calling bullshitA performative utterance repudiating something objectionable; scope is broader than bullshit — you can call bullshit on lies, treachery, trickery, injusticeFinding a reputable source that refutes a rumour; citing Snopes
Reductio ad absurdumRefuting a claim by deriving an absurdity from its logical extension or from the denial of itWomen’s running times: if the trend continued, they’d eventually run 100m in 0 seconds
Null modelA model showing what we would observe in a simple system where not much is going on; tests whether alternate explanations fit the same dataThe fastest runner isn’t necessarily the oldest — it’s the one in the largest sample; the age effect disappears when sample size is controlled
