> Several patients have presented with transient "Capgras delusion", a psychiatric disorder in which a person believes someone close to them has been replaced by an impostor. > "It's quite disturbing because, for instance, a patient would tell his wife: 'Sorry ma'am you cannot get in bed, I'm a married man' and even if the wife gives her name, he'd say: 'You're not the real one,'" Dr Marrero says. You could spice up a lot of marriages if you could harmlessly cause Capgras delusion for a few hours

As long as you induce it consensually, right? It sure would be uncomplicated, no real third party needed.

  That... wouldn't work. Consent must be continually given, and for Capgras to work you can't be aware it's a delusion at the time you're experiencing it.

    I think the idea is that if you wanted to spice up a marriage with an affair, you could use this to "cheat" on your spouse with your spouse. Both parties would be consenting the whole time. One would just think they are cheating.

      Oh, I understand the concept. It's broken. If I am "consenting", but not to the action that's actually happening, I am not, in fact, consenting. If I believe that I am consenting to sex with someone that's not my husband, in that moment I am not consenting to sex with my husband. If they then have sex with me, knowing that that is my state of mind, that is non-consensual.

        You do not understand the concept: I decide I want to try a bit of "something new", and I pay someone to induce a Capgras delusion in me. At which point, my wife seems like an imposter. I wish to have sex with this new person, and I am also sure my real wife has given me permission to, prior to this. You can tell me as much as you like that it's "really" my wife, but, in my delusion, I am quite sure it's just someone who looks like her, and delightfully and consentfully have sex with the imposter new person -- who is giving their consent the whole time -- with all the thrill that entails. Afterwards, the delusion wears off, and I realise it was just sex with my wife. Everyone has consented at every point to this.

        I do understand the concept. You have not changed my understanding with this description. If I am suffering a delusion, and you know that, then you know that I am not mentally competent. You know that, if I agree to something, I do not correctly understand what I am agreeing to. Any expression of consent you extract from me is invalid.

        This seems extreme. You are consenting to be deluded, knowing everything that will come afterwards. And the consenting during as well
        regularfry 5y ago
        But you don't know everything that will come afterwards. You know what's planned. The consent during cannot be valid. It's not informed: in fact it's specifically misled, and that is known to the other participant.

        So you are saying there is no way for two willing, informed adults to consent to this happening?
