The "connection between things that are not really connected" part match my own experience of having schizophrenia very well.

It's not uncommon for me to have thoughts that very much makes sense and is meaningful to me while others simply can't make any sense of it what-so-ever.

This means I'll have to be cautious of my own thoughts and I often doubt them.

Thoughts as well as meanings change over time too. Sometimes I write down ideas I think is brilliant to save for later. Revisiting those writings can be troubling because I might not be able to make a similar sense of what I wrote earlier.

Thanks. I can see how this would lead to "derailments", particularly if the story line was modeled as arcs (given it's a "connectionist model"), but the "delusions" seem less obvious... unless things, including identities, were also modeled as arcs between different ways of referencing the same thing (e.g. my address, where I live, my home). Sort of using the same model for instances (events in a story) and schema (actors in a story) - which makes sense, and may well be how it works in the brain. Reuse, don't reinvent, is what nature does when it can.

I have doubts about Science based on making up computer models and seeing what happens (although it is a lot of fun to do). OTOH, they clearly casting this as merely a hypotheses - which is pretty reasonable.
