a new idea, bred from Faith × Placebo
Fidivacua aperta·the Open Trust
From Latin fides, trust, and vacuus, empty, and apertus, open; an open trust in something empty.
Its kinds · Roget, 1852: Formation of Ideas · Wilkins, 1668: Spiritual Action · WordNet, 1990: Act · Llull, 1308: E · Man
Trust given knowingly to something empty can still change the one who gives it, because what acts is the act of trusting, not its object.
You can trust what you know to be empty, and it still holds you.
behavior Holds out an empty shell with great care, and glows only while it is being held.
What would you keep doing if you were told it was only a gesture?
Each organ answers one question about the idea. The framed one, its kernel, is the dominant organ: the being's class, the one the idea could not lose and stay itself.

❦ dominant organinherited from FaithWhich premise, if it were false, would kill this idea?
Trust given to something one knows to be empty still acts, because what changes the one who trusts is the act of trusting, not what it is given to.3, 2

Open label
inherited from PlaceboWhat sets it apart from what it is not, and how does it keep that distinction?
It is set apart from faith by knowing its object is empty, and from pretence by meaning it; it lives in the trust that survives being told the truth.3

Healing ritual
inherited from FaithWhat must it feed on to work? What has to be present, noticed or supplied?
It feeds on a gesture of trust made openly, a pill taken as a pill, a charm carried as a charm, a rite kept by someone who no longer believes its story.2

Fig. 4. Mechanism
Response expectancy
inherited from PlaceboHow does it turn what it takes in into what it gives out?
Committing to the gesture sets up an expectation that body and mind answer, even when the one who commits has been told there is nothing inside.3, 4

Fig. 5. Output
Placebo response
inherited from FaithWhat does it make possible, visible or knowable?
It gives relief, steadiness and courage without deception, so that a doctor can offer it honestly and a sceptic can use it.4

Fig. 6. Dispersal
Placebo arm
inherited from PlaceboWhat part of it travels into other minds, ideas and fields, and by what vector?
It travels as open-label trials, as a doctor saying plainly that this is a sugar pill and it may help, and as the habits of people who keep rites they no longer believe.3, 1

Fig. 7. Decay
Null result
inherited from PlaceboWhat can it not digest, where does it fail, and what does it leave behind for others?
It cannot be summoned by knowing alone; without the gesture and the care around it it does nothing, and some of its supposed effects, such as the lucky charm's, have failed to replicate.5, 6

practice
A short script for offering an open-label placebo in general practice, saying what the pill is, why it may help, and asking the patient to take it with the same care as any medicine, tried first for chronic pain and irritable bowel, where the trials are.3, 4
What can you give someone that works because you told them the truth about it?
study
Give open-label placebos to two groups with the same honest explanation, one with the full ritual of care, time taken, a careful hand-over, a follow-up call, and one with the pills simply posted, and compare their relief. If the ritual carries the effect, it is the act of trusting that acts, not belief in the pill.3, 4
What would you keep doing if you were told it was only a gesture?
artwork
An exhibition of reliquaries made to be openly empty, each labelled as such, which visitors may take in their hands for a while, then leave a word about what holding it did. It asks whether care given to an empty vessel still changes the one who gives it.
Can you trust something you know to be empty?
bridge Both are predictions that help make what they predict; what is expected arrives partly because it is expected.
friction Faith assumes its object is real, though unseen, and is wounded by disproof. Placebo's object is known to be empty by the one who gives it, and in open-label use by both.
tension Can trust in something known to be empty still act, and if it can, what is being trusted?
questions neither parent could ask
pollination: What happens to a remedy made only of meaning when it travels the way faith travels, by witness, from one person to the next?
| candidate | emergence | depth | ground | distance | total | |
|---|---|---|---|---|---|---|
| votive-wall | 2 | 2 | 3 | 1 | 8 | A shrine already joins faith and healing; Placebo adds little that Lourdes does not have. This is faith healing again. |
| witness-balm | 3 | 3 | 3 | 2 | 11 | It needs Placebo's premise that meaning alone acts and Faith's vector that meaning passes by witness. Observational placebo analgesia, placebo by proxy and mass sociogenic illness are all measured. It is close to the known idea of social contagion, hence 2 on distance. |
| testimonial | 1 | 1 | 3 | 1 | 6 | Mostly Placebo's own intake, the look and price of the remedy. |
| feed-of-recoveries | 2 | 2 | 1 | 2 | 7 | Nothing shows that a screen passes relief the way a person in the same room does. |
crossing: What is a trust given to something one knows to be empty, and why does it still act?
| candidate | emergence | depth | ground | distance | total | |
|---|---|---|---|---|---|---|
| knowing-trust | 3 | 3 | 3 | 2 | 11 | It needs Faith's premise that acting on a trust makes it real and Placebo's finding that the effect survives disclosure. Open-label placebo trials in irritable bowel syndrome and back pain ground it. It is near the open-label placebo itself, hence 2 on distance, but it reaches past medicine to rites and charms. |
| as-if-rite | 2 | 3 | 2 | 2 | 9 | Vaihinger's philosophy of as if already holds it; Placebo adds little to Ritual here. |
| honest-charm | 2 | 1 | 1 | 2 | 6 | The study that found lucky charms improved performance did not replicate. |
| self-prescribed-sugar | 1 | 1 | 2 | 1 | 5 | Placebo alone, sold. |
