I suspect we have a variable number of supplemental threads of execution serving the primary one we live on. Recalling distant memories asynchronously after struggling to remember anything about it sometimes feels very much like another person interrupting and delivering the information once it's found.

But there's always an immediate trigger

I'll check out those titles, but put simply, are you referring to how I talk to myself in many voices in the shower, having a narrative about a problem I'm picking away at?

TLDR of HBTM is that there is a nonverbal, background thread of consciousness in your mind. It has the advantage of a larger working set (short term memory) compared to the verbal, foreground thread. Therefore it can more easily integrate more complicated observations over time than your foreground thought process. It has the disadvantage that it is non-verbal and does not work quickly, on command or under pressure.…

I've used this for a long time. Observations:

- explains "prayer": talk it over with your God, leave it in God's hands, you get an answer.

- may have gteater survival value than the chatter we think of as "consciousness", and may be the actual intelligence that we're famous for.

Fascinating. Thank you.

btw: Your shower routine sounds like http://wiki.c2.com/?RubberDucking

The act of explaining a problem verbally to someone else forces you to be explicit about details that you gloss over when you think about the problem internally. The fun part is that you don't actually need a real person to explain to. Just going through the motions and explaining out loud to no one (or to a toy) is nearly as effective.

Another interesting read is “The Origin of Consciousness in the Breakdown of the Bicameral Mind” by Julian Jaynes, which outlines hypothesis of bicameralism [1]. [1] https://en.wikipedia.org/wiki/Bicameralism_(psychology)

The hypothesis of bicameralism is mostly debunked, though.

Any references?

Iain McGilchrist discusses at length the two-sided brain in his book The Master and His Emissary: The Divided Brain and the Making of the Western World [1]

Fun fact: He wrote the book over a period of 20 years.

Idea of “decentralized” brain perfectly explained in Michael’s Gazzaniga book “Who's in Charge? Free Will and the Science of the Brain”. He’s the first guy who makes experiments on split brain and found decisions making center which works like telling and explaining machine. Recommend.

His book “human” is also very good

Reminds me of Willpower instinct book that has similar but with the hypothesis that the prefrontal cortex is the "executive in charge of" type of brain.

There's a related phenomenon that I've experienced. Some of my best insights into problems have come to me when I was either very tired, drowsy, or slightly ill - like running a mild temperature. I wonder whether this is because the condition knocks out the foreground process, while not being drastic enough to knock you out fully.

Sure, they're cooperating, for now :)
