What you are describing is the "Stress-Diathesis Model." The rough explanation is that many people have vulnerabilities for mental illness (including schizophrenia, bipolar disorder, major depressive disorder, and others), and that the vulnerability is triggered by environmental stressors. It is in some ways similar to the "two-hit hypothesis" for cancer. A search for "Stress-Diathesis Model" will yield a lot of hits in the academic literature. It's well accepted as at least part of the explanation for why some people with a genetic vulnerability develop symptoms and others do not.

Thank you for your insight, and for referring me to the proper literature on the subject. It's very much appreciated.

Amateur here ... don't a lot of people have schizophrenic symptoms (voices), but as long as they are positive or the person can ignore them it's usually just ignored? Like, some people might have "imaginary friends" who they chat to about the weather, quietly. Other people have "imaginary friends" who they have screaming arguments with. In some cases, could stress either make the delusions / voices less benevolent, or send people into a cycle in which they are no longer able to manage them?

  some people might have "imaginary friends" who they chat to about the weather, quietly. Other people have "imaginary friends" who they have screaming arguments with. That's very interesting. I hadn't heard of that before. I wonder if it'd be possible to conduct an anonymous survey as to whether people have imaginary friends that they routinely chat with or get into screaming arguments with? I wish such a survey could be trusted, but it'd probably attract troll results.

    You might find "the origin of consciousness in te breakdown of the bicameral mind" interesting. It references studies as such. It's from 1975, and either a stroke of genius or complete crackpot. But it is interesting, well argued, and potentially mind blowing. I have no idea if anyone studied voices among normal people since this book was published.

      Julian Jaynes' book was required reading in my geeky circle of friends, and the root of many "voices of the gods" jokes. Good for endless drunken campfire discussions. Basically, he said that before we developed language, the voices of the gods ('imaginary friends', 'voices in our heads') told us what to do when instinct didn't. The development of language pushed out the voices of the gods. I don't remember much more than that. I heard that he had retracted the whole thing, but can't find any evidence of that retraction.

        My understanding is that it's not "before we developed language" - but rather, before we developed modern culture, which silences these voices ("imaginary friends") during upbringing. However, Jaynes argues that various conditions (schizophrenia, non-schizo "voices") are a non-silences version of that natural tendency, albeit often harmful - the revenge of the forgotten imaginary friends, if you will.

  About to make the same comment. I have not had any contact with a schizophrenic sufferer. The closest I got was via the movie "a beautiful mind", which is pretty distant. In that movie, it seems to portray the life of a schizophrenic sufferer as you have described it, but I really wonder how close it is to reality.

  The voices with schizophrenia are outside of the head, a voice heard often clearly as though they were physically spoken. They are consistent auditory hallucinations. These can be quite nutural; one sign of paranoid schizophrenia is the voices making a running commentary of everyday actions. If people are having chronic hallucinations, whether positive, nutural or negative, it's something to be concerned about. Usually there are symptoms outside of these hallucinations in this case where sufferers are not able to look after themselves. In patients with bipolar during a manic/hypomanic phase, I could except hallucinations to be very positive in nature, such as supporting delusions of grandeur. This may be much different from talking to ourselves or physically responding to dialogue WITHIN our heads, which I imagine is the source of many imaginary friends. EDIT: I'm not qualified to speak on these subjects but I suffered from psychosis from a number of years and was misdiagnosed with schizophrenia at one stage due to the nature of my hallucinations (though still a bit over zealous on the psychiatrists part). I naturally came to learn a lot about what it is, how it's treated and spoke to many patients with psychotic illnesses in my stay in hospital (for mental disorders, a stay of 3 - 4 months is a short amount of time, many who I was in there with had been in for a year or more)

    "a voice heard often clearly" That's interesting. I had assumed coming from a RF EE kind of background that it was very much like having a gain control turned way up from a noisy input resulting in peculiar signals being demodulated, but perhaps not so. For example last night the weather was really awful and at the limit of perception almost asleep (well, I was probably actually asleep) I thought I heard a very unhappy cat meowing outside, so I actually got up and tried to find it, perhaps let it in my dry warm garage to warm up a bit. No cat existed of course. So under my hypothesis if I had the disease I would hear phantom cats and stuff in general all the time not just once, maybe multiple ones at the same time, and specifically in that situation hear my wife (soundly sleeping like everyone else) telling me loudly and clearly to let the stray cat in to warm up, verbally and clearly and loudly. However the alternative model, is I'd solely hear the wife telling me to let the stray cat in to warm up, maybe not even hearing the phantom meow. An individual spurious signal model vs a generally increased noise level model. A side orthogonal issue might be requiring it to have substantial influence on life. While almost asleep I once thought I barely heard a stray meow outside in the freezing rain so I got up and looked out the windows for a minute has no real influence on my life as an isolated although unusual incident, in comparison, constantly hearing voices loudly tell me peculiar things would have a huge influence on my daily life. So that is interesting too.

My mother developed schizophrenia after a nervous breakdown. In my family circle, it is colloquially said she 'got it' from stress, because her parents constantly argued and built a stressful environment for her. As her child, I was always scared of developing it, because there were times when I definitely had scary symptoms. I learnt about various hypothesised causes or things that could 'bring it about', so I never did drugs and practised ways to keep myself calm (I used to be extremely nervous, had sweaty hands and feet, etc.). Now that I'm 31, I think I've done pretty well. Even with medication, my mom cannot really identify who I am, though. I guess I just want to thank you for sharing your knowledge about schizophrenia.
