New Data

Participant 3

  • Predicted prices would go down, but not enough.
  • Based theory on switch to alternative fuels due to pollution and government regulation.
  • New explanation used old one with an additional statement (warmer weather leading to lower demand).
  • Made constant confidence estimates for forecasts.
  • Made forecasts with similar pattern to prior data.


  • Confused by the similarity judgments; this needs to be rephrased.
  • I think the P(Theory) question is not specific enough. People seem to think it is asking "how likely is it that your explanation describes a relevant causal factor" rather than "your explanation describes all the relevant causal factors"


  • Changed similarity question to: "How similar are the actual prices of coal between 1980 and 2010 to what you would predict based on Explanation Two?"
