I think this might also have been mentioned in Unlocking the Emotional Brain, though I’m not entirely sure if it was or if I just figured it out after reading it. Namely, that if one’s fear is “doing X will inevitably cause Y to happen”, then finding counterevidence can be relatively easy. You just need to find a single instance where it doesn’t happen. But if the fear is “doing X might cause Y to happen”, then Y simply failing to happen won’t trigger reconsolidation.
