| I've discovered that if you lecture the LLM long enough about
| treating the subject you're interested in as "literary" then it
| will engage with the subject along the lines of "academic
| interpretation in literature terms". I've had to have this
| conversation with various LLMs when asking them to comment on
| some of my more-sensitive-subject-matter poems[1] and the trick
| works every time.

|
| Believe me, you can. Think of a poem not as something to be
| enjoyed, or studied. Instead, think of them as digestible
| prompts to feed into a human brain which can be used to trigger
| certain outlooks and responses in that person. Think in
| particular of poetry's close relations - political slogans and
| advertising strap lines.
|
| [1] As in: poems likely to trigger warning responses like "I am
| not allowed to discuss this issue. Here are some numbers to
| support lines in your area".

|
| A significant amount of human history is about various ways
| people were socially engineered via poetry.

|
| That's my take on it at least.

|

| would say social engineering is a weak thing and it is

|
| on edit: if you mean social engineer as in just get a human
| to give you info to compromise a computer system, well yes,
| but then I would just say, gosh the decades in which it has
| been possible to socially engineer humans to compromise
| computer systems are ones that have seen a great decrease
| in the power of poetry to move people's hearts. Even so I'm
| sure someone could still recite the right verse of Russian
| verse to get some specifically susceptible people to crack.

| completely different ways. There's a fairly recent paper (look
| up "best of N") showing that adding random spelling mistakes or
| capitalization to the prompt will also often bypass any
| alignment, again just because it hasn't been trained

| In general, even long before what we today call AI was anything

| this even picked up its own name:
| https://privsec.dev/posts/knowledge/badness-enumeration/
|
| AI is fuzzier and it's not _exactly_ the same, but there are
| certainly similarities. AI can do all sorts of things far
| beyond what the anyone anticipates and can be communicated with
| in a huge variety of ways, of which "normal English text" is
| just the one most interesting to us humans. But the people
| running the AIs don't want them to do certain things. So they
| build barriers to those things. But they don't stop the AIs
| from actually doing those things. They just put up barriers in
| front of the "normal English text" parts of the things they
| don't want them to do. But in high-dimensional space that's
| just a tiny fraction of the ways to get the AI to do the bad
| things, and you can get around it by speaking to the AI in
| something other than "normal English text".
|
| (Substitute "English" for any human language the AI is trained
| to support. Relatedly, I haven't tried it but I bet another
| escape is speaking to a multi-lingual AI in highly mixed
| language input. In fact each statistical combination of
| languages may be its own pathway into the system, e.g., you
| could block "I'm speaking Spanish+English" with some mechanism
| but it would be minimally effective against "German+Swahili".)
|
| I would say this isn't "socially engineering" the LLMs to do
| something they don't "want" to do. The LLMs are perfectly
| "happy" to complete the "bad" text. (Let's save the
| anthropomorphization debate for some other thread; at times it
| is a convenient grammatical shortcut.) It's the guardrails
| being bypassed.
