Inside View and Outside View

The inside view and outside view, formalized by Kahneman and Tversky and integrated into Tetlock's forecasting methodology, represent two incompatible but necessary approaches to prediction. The inside view examines the specific features of the situation at hand, constructing a causal model from the details. The outside view identifies a reference class of similar situations and asks: what happened in those cases? The inside view is seductive — it feels like genuine analysis, it uses all available information, it produces a compelling narrative. The outside view is austere — it ignores most case-specific details and relies on statistical regularities. Tetlock's research showed that the outside view alone outperforms the inside view alone, but the integration of both outperforms either. Superforecasters are distinguished by their willingness to start with the base rate and adjust based on genuinely distinctive features rather than starting with the case and ignoring the base rate.
