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.

: 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.

: 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.

: 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.

: 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.

: how likely a card is preferred. Verbal accessibility : how likely a card is chosen when asked to name one.

: 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.
