8 Inductive Reasoning

  1. In inductive reasoning, conclusions are inferred from evidence but are never guaranteed to be
    correct. Their degree of certainty is based on a continuum of weak to strong evidence. Strong
    inductive arguments are based on a substantial number of observations, diversity of evidence,
    and representativeness of the observations.
  2. Inductive reasoning is often compared to deductive reasoning. Both of these forms of
    reasoning are central to critical thinking and involve evidence, logic, and working memory.
    However, induction and deduction differ in the types of evidence on which they are based
    and how they are evaluated. In addition, inductive conclusions go beyond the evidence or
    premises and are educated guesses; deductively valid conclusions follow directly from the
    premises and are guaranteed to be logically true.
  3. Inductive reasoning is widely used in everyday life. Humans often automatically make
    predictions about what will happen next based on what occurred in the past. In addition,
    this form of reasoning plays an important role in other cognitive activities, such as decisionmaking,
    categorization, and similarity judgments.
  4. The availability heuristic is a cognitive short-cut used when people easily retrieve information
    from memory and perceive it as relevant evidence for the likelihood of a phenomenon.
    Although this heuristic is sometimes useful, it can undermine the diversity of evidence needed
    for strong inductive arguments. It can also result in illusionary correlations.
  5. Confirmation bias also limits the diversity of evidence. This bias occurs when people use
    enumerative induction and only seek observations that support their hypotheses. Eliminative
    induction is more informative because it is based on seeking evidence that both confirms and
    disconfirms a tentative hypothesis.
  6. The representative heuristic allows us to infer the probability of an event by assuming it is
    similar to a prototype event. However, this heuristic can result in weak inductive arguments if
    base rate and sample size are not considered.
  7. There are several forms of inductive reasoning, including category-based inductions, causal
    inductions, analogical reasoning, and insight. At some level, they are all based on finding
    similarities in a situation.
  8. Category-based induction involves generalizing a property of one category member to a
    member of another category. Premise typicality, premise-conclusion similarity, premise
    diversity, and premise monotonicity are taxonomic relations used by novices when reasoning
    inductively about a relevant domain. In contrast, experts in a domain apply causal, ecological,
    or thematic relations.
  9. Causal induction involves predicting what causes outcomes. If a hypothesized cause and
    effect are both present at the same time and absent at the same time, a causal induction is
    confirmed. If one is present when the other is not, the induction is disconfirmed. When
    causal relations are indicated in category-based problems, they over-ride the use of taxonomic
    relations in making inductive generalizations.
  10. Analogical reasoning involves comparing two domains in order to infer a quality they have
    in common. Relational similarity is necessary for this form of reasoning, although surface
    similarity can foster the mapping of relations between the domains.
  11. Insight involves perceiving information in a new way, which often requires cognitive restructuring
    of our mental representations. It is often accompanied by a subjective feeling of “Aha”
    or not consciously knowing how one arrived at the new perception. Functional fixedness or
    fixation on unproductive procedures can hinder this form of inductive reasoning.
  12. Inductive reasoning begins early in life and there is evidence of both continuity and change
    in its development. Cognitive changes and a larger knowledge base allow older children to
    perform more complex category-based inferences, causal inductions, and analogical reasoning,
    while becoming more susceptible to functional fixedness.
