““The anti-precog has to be present when the precog is in the process of deciding, not after. The anti-precog makes all futures seem equally real to the precog; he aborts his talent to choose at all. A precog is instantly aware when an anti-precog is nearby because his entire relation to the future is altered. In the case of telepaths a similar impairment—” “She goes back in time,” G. G. Ashwood said. Joe stared at him. “Back in time,” G.G. repeated, savoring this; his eyes shot shafts of significance to every part of Joe Chip’s kitchen. “The precog affected by her still sees one predominant future; like you said, the one luminous possibility. And he chooses it, and he’s right. But why is it right? Why is it luminous? Because this girl—” He shrugged in her direction. “Pat controls the future; that one luminous possibility is luminous because she’s gone into the past and changed it. By changing it she changes the present, which includes the precog; he’s affected without knowing it and his talent seems to work, whereas it really doesn’t. So that’s one advantage of her anti-talent over other anti-precog talents. The other—and greater—is that she can cancel out the precog’s decision after he’s made it.””
