Let's say you have an idea that you think might be interesting to investigate, possibly a new aspect in AI safety, maybe some new algorithm.

If you're an experienced researcher, you probably have plenty of intuition to think through it, consider the possible outcomes and decide whether it's worth investigating.

If you have a decent academic network, you can probably bring it up even in casual conversations with people who are as good or better than you in the field to get a sense of their intuitions.

What if you have none of those things? Is there an online forum for such discussions, just like I'd go to reddit when looking for e.g. game recommendations? Maybe *this* is the forum?

And are there any good recommendations how to try and work it out by yourself, without referring to the wisdom of online crowds?

Let me try to point you in the direction that has been useful for me. I figured getting an answer to you was more important than getting a well-edited reply. Sorry for my logorrhea. If you would like to have a one-on-one conversation let me know.

10 second background: I spent most of my 20s in a good Ph.D. program in Applied Physics. I've spent the last 10 years in the corporate world and devoted a lot of time developing new statistical models. My answer is going to be colored by that past.

You correctly pointed out that having a good network to bounce ideas off of is the best first place to look. But since you came here and I'm the first to answer, that probably isn't enough. I have some tips on how to establish one, but that's a longer term goal and it sounds like you want to get started now. I can elaborate on what worked for me if you want.

My biggest tip came to me from my Ph.D. advisor. You probably aren't reading enough in your field. You should be reading (at least abstracts) a lot. I probably go through about 100 papers a year (maybe 10-20 read deeply), and I'm now mostly just part time research. If you want to do this seriously, you are going to need to know what's going on outside of your own head. First step, get the good text books in the field and ideally read them, but at least know the topics. After that, find out what the important journals are and where you can find the new and exciting papers. The arXiv is where I typically start looking, but google scholar is also a very strong contender for finding relevant papers. This should also get you familiar with who is doing similar work. Some (frequently most) of them will be friendly and approachable people. If you can find a contact of somebody local, hold on to it.

Sometimes it'll take a few weeks of research to find out that the great idea of yours has already been discovered and goes by some specific name. Clearly, start reading about that, but don't be discouraged. A new look at an old idea is frequently worthwhile, especially if you're just starting. It's also possible that you've found something entirely new. Either way, as you learn more, try to actually do something with your idea. e.g. take an easy special case of what you're thinking about and code it / do the math / figure out logical implications. This does a couple of things for you. First, if will tend to tell you if the idea has merit or is just junk. All of us have had it go both ways, don't get discouraged. Secondly, it'll open up more avenues of thought that will likely lead you to other sub-fields to start reading about. Do the reading. But finally, it'll give you something concrete to talk about. If you have an interest result, and here small and easily explained is ideal, write it down somewhere. It doesn't have to be much, a couple of pages is fine. Use Nassim Taleb's arXiv page as an example.

In my experience, doing the first bit of work on the new idea is critical. Once you have some result, and know what's going on with other researchers, you've set yourself up to be taken seriously when you ask for opinions or help. If your method of writing up the proposal is getting seen by somebody in your field, then you're already done and can start getting feedback about the validity of the general idea. If not, my tactic has been to write a short (can't stress this enough, keep it short) email asking an author of a related paper that you have read (I have had the best luck with post-docs and grad students) if they can recommend a good source of a survey of the field. With luck, this will start a conversation where you can ask what they think of your first result. If it isn't dismissed, that will probably open the door to start a conversation about the larger topic you are interested in.

TLDR: Read everything you can find in the area. Develop some small portion of your idea to completion to teach yourself and seed future conversations. Reach out to somebody that you found in your reading.

Also a PhD here - read, read, read. You need to know what's been done to see what the gaps are and how your project would fit in. You will also build up that intuition.

Sure, it's also helpful to be able to bounce ideas around your network, but the less well-formed the idea is, the more likely it is to go to friends who aren't just going to shoot you down or for it to get the benefit of the doubt as "early-stage." You need to get the idea formed to the point where someone can feel comfortable pointing out issues, which will take ind... (read more)
