What makes Arm C2 different

  • • Eight of the nine boxes are Arm C1, word for word.
  • • Two extras went into one box, and no new arrow was added.
  • • Guess the payoff of an answer, and reuse the saved first question.

More clever, and worse

  • • Right 68 times out of 144, where C1 got 77
  • • Wrongly flagged a must-report disease 37 times, where C1 did 30
  • • One tested behaviour fell from 12 right out of 24, to 6

We kept it as a warning

  • • Not promoted. The drop belongs on the box, not in a footnote.
  • • The sealed pack ran C1 only, so this is rehearsal evidence
  • • Research only. Nothing is deployed.
