One of the most basic assumptions about intention is that it operates according to a generally accepted sense of cause and effect: if A causes B, then A must have happened first. This assumption reflects one of our deepest beliefs, that time is a one-way, forward-moving arrow. What we do today cannot affect what happened yesterday.
However, a sizeable body of the scientific evidence about intention violates these basic assumptions about causation. Research has demonstrated clear instances of time-reversed effects, where effect precedes cause. Indeed, some of the largest effects occur when intention is sent out of strict time sequence.
