Hi, one of the Davids from philosophy club here. (The quieter one.) First thought: What are some predictions you'd make based on these notes? It seems like some of them ought to be testable through informal experiments.

Some small things:
Rather than reducing the detail, it seems like looking away is more an instance of totally avoiding the input. I think we also observe the opposite, eg, people reading up (and becoming upset) about crimes, perhaps particularly relevant here, crimes that happened in places distant in time and place so seemingly not pursued out of any more overriding reason -- not to learn avoid immediate danger, etc.

Why prefer copying over strength as metaphor? I think neural networks are one of the main examples of architecture for and example of parallel processing, and they work in terms of weights, I think.

Well, I'll stop here for now, but I'm happy to have found this and look forward to reading more. I'm particularly curious about your business.

I also thought I would point out this: http://www.lpsf.org/ I believe their next meeting will be on June 12th.

Hi David,

Nice to hear from you!

There are indeed some testable predictions; I will enumerate some of them soon.

Re: reducing the detail. When you turn away, it does indeed remove the sensory input, but there's still plenty of representation of the event that remains in a mind. Sensory input is really only just one way of creating representations in a mind. If you really removed the detail, then you would instantly forget that the event even existed.

Re: reading about crimes. There is indeed a value to reading about the crime. However, the gory details of the crime (a graphic feature of the decapitated victim) are usually not published because they would be truly upsetting. I think that some people get a positive emotion from reading about a crime, especially if it happens to a celebrity, because they think "Hah, they might be rich & famous, but they can still be a victim of a crime". (see any national enquirer for examples of this).

In a distributed system, you don't want just one copy of anything, even if it's strengthened, because it's a single point of failure. If that copy is destroyed (and neurons die all the time), then you would forget that rule. Instead, if you copy things you want to remember, then the most useful things become more fault tolerant as well as stronger (based on the combined "voting" of all the copies).

Thanks for the libertarian party link - I must go to one of those events soon!

  • Destiny is my science fiction movie about the future of humanity. It's an epic, similar in breadth and scope to 2001: A Space Odyssey.
