Inference to the best explanation

Definition

Inference to the best explanation is a reasoning process where one evaluates various hypotheses or explanations and concludes that the one which best accounts for the available evidence is likely true. This method is essential in understanding how we form beliefs based on incomplete information and makes connections to broader themes in justifying inductive reasoning and scientific realism.

5 Must Know Facts For Your Next Test

1. Inference to the best explanation helps justify induction by suggesting that some hypotheses are more plausible based on how well they explain observed data.
2. In scientific contexts, this method supports scientific realism, as it posits that our best scientific theories accurately depict unobservable phenomena.
3. This reasoning method often considers criteria such as simplicity, scope, and explanatory power when evaluating competing explanations.
4. Inference to the best explanation is crucial in scientific practices where evidence is incomplete, guiding researchers toward the most viable theories.
5. Philosophers debate the reliability of this inference, as it involves subjective judgment about which explanation is indeed the 'best'.

Review Questions

• How does inference to the best explanation serve as a justification for inductive reasoning?
  • Inference to the best explanation acts as a justification for inductive reasoning by helping individuals determine which hypotheses provide the most coherent account of observed phenomena. By evaluating different explanations based on their ability to account for existing evidence, people can make reasoned predictions about future occurrences. This approach enhances the reliability of inductive reasoning since it encourages choosing those hypotheses that are not only plausible but also comprehensive in explaining data.
• Discuss how inference to the best explanation relates to scientific realism and the no-miracles argument.
  • Inference to the best explanation underpins scientific realism through the no-miracles argument, which asserts that the success of scientific theories would be inexplicable if those theories were false. By claiming that our best scientific explanations correspond to reality, this reasoning aligns with a realist perspective that treats successful scientific theories as reliable descriptions of both observable and unobservable aspects of the world. Therefore, this inference provides a foundation for believing in the truth of scientific theories because they offer the best explanations for empirical data.
• Evaluate the implications of relying on inference to the best explanation within scientific inquiry and its potential limitations.
  • Relying on inference to the best explanation within scientific inquiry has significant implications, including guiding researchers toward developing robust theories based on available evidence. However, this approach also faces limitations, such as subjectivity in determining which explanation is truly 'best,' potentially leading to biases. Additionally, when evidence is scarce or ambiguous, different scientists might reach contrasting conclusions based on their interpretations. Thus, while it is a valuable tool for theory development, care must be taken to ensure rigorous testing and validation of explanations.
