Here's a good post about this [0], including this gem: > Schiltz is a psi believer [... but Wiseman] is a psi skeptic [...] > The idea was to plan an experiment together, with both of them agreeing on every single tiny detail. They would then go to a laboratory and set it up, again both keeping close eyes on one another. Finally, they would conduct the experiment in a series of different batches. [...] > The results? Schlitz’s trials found strong evidence of psychic powers, Wiseman’s trials found no evidence whatsoever. Running experiments and collecting data is necessary, but not sufficient. Bias and other failures are extremely hard to avoid. Saying "it's not science" is (derogatory) shorthand for the assertion that their results are due to failures in their process, as opposed to being reflective of reality. 0: http://slatestarcodex.com/2014/04/28/the-control-group-is-out-of-control/ http://slatestarcodex.com/2014/04/28/the-control-group-is-ou...
