  • Skeptics accept new ideas as long as their methods support them
  • We have separate memory stores for facts, truthfulness of those facts, and fact sources; this is why we sometime jumble where we heard what
  • Memories are subject to co-fusion, confabulation, and co-opting from others
  • Confidence and vividness have little bearing on accuracy
  • Only the eye’s fovea captures details, it is the size of a postage stamp at an arm’s length, all other details are made up
  • The brain does pre and post processing, enhancing the image based on what we think we are looking at
  • Pareidolia is the brain trying to make sense of noise
  • Beware of defenses that are created on the fly
  • When ranking things we want, if our first choice is not available, we tend to skip the third. Maybe because we already had to dismiss the second when picking the first.
  • “If you torture the data long enough, it will confess to anything.” Ronald Coase
  • Anomaly hunting goes wrong when we ask “what are the odds [this] happening?”. The good question is “What are the odds that any anomaly would happen?”
  • Random data is “clumpy”; expect to see weird things together
  • P values indicates the quality of the data, not the truthiness of the hypothesis
  • Hybrid seeds cannot be replanted because they will have unpredictable gene expression
  • We tend to confuse the knowledge of experts with our own knowledge
