Our studies on the psychology of card magic measured seven specific factors:

  • Visibility sensitivity: how well a card is detected among other cards. Higher values mean easier detecting.
  • Visibility bias: how likely a card is declared present compared to absent. Lower values mean more likely to be declared present when detecting.
  • Memorability sensitivity: how well a card is remembered among other cards. Higher values mean easier remembering.
  • Memorability bias: how likely a card is declared present compared to absent. Lower values mean more likely to be declared present when remembering.
  • Likability: how likely a card is preferred.
  • Verbal accessibility: how likely a card is chosen when asked to name one.
  • Visual accessibility: how likely a card is chosen when asked to visualise one.

Below are the average data for each card, from the Ace of Spades (AS) to the King of Diamonds (KD). Click on a column heading to sort by that column.
