The Eight Phases · 5 of 8

Phase 5: Installation

Desensitization empties the negative. Installation fills the space with something the client can actually stand on.

Once a target's disturbance has dropped to zero, there's an opening. The memory network, no longer flooded with the old charge, has room for a more accurate belief to settle in. Phase 5, installation, is where that happens — and skipping or rushing it leaves the work half done.

Re-checking the positive cognition

You return to the positive cognition named back in Phase 3 and ask whether it still fits. Often it has evolved — the client who wanted to believe "I'm safe now" may, after desensitization, land on something truer, like "I can protect myself." You honor the shift. Then you pair the memory with the chosen PC and run sets of bilateral stimulation, checking the VOC each time.

The negative belief was installed by an experience. So is the positive one — you're just letting the brain finish the sentence.

Toward a felt 7

The aim is a VOC of 7 — the belief felt as fully true in the body, not merely conceded in the head. You keep adding sets while the VOC climbs. If it stalls short of 7, that's diagnostic: usually a residual channel or a blocking belief that Phase 4 didn't fully clear. You return to desensitization on that fragment, then come back.

Ecological validity

Sometimes a 7 isn't appropriate, and forcing it would be dishonest to the client's reality. "I'm completely safe everywhere" is not a belief you want to install in someone whose environment carries genuine risk. A grounded VOC of 6 that respects real-world conditions beats a hollow 7. Good installation is truthful, not just positive.

When installation is complete

With the PC strong and the VOC as high as reality allows, you move to Phase 6: Body Scan to check whether the body agrees with what the mind now believes. Installation depends on a clean Phase 4; if the positive won't hold, the negative usually isn't fully cleared.

For clinicians

Reinforce the new belief daily

Rewire's positive-cognition check-ins let clients keep noticing what's now true — quietly strengthening Phase 5 gains between visits.
