I was recently thinking about focus. Some examples:

The internet provides access to an education that the aristocracy of old couldn't have imagined.

It also provides the perfect attack vector for marketers to exploit cognitive vulnerabilities and dominate your attention.

A world-class education is free for the undistractable.

Sam Altman's recent blogpost on How to Be Successful has the following two commands:

3. Learn to think independently

6. Focus

(He often talks about the main task a startup founder has is to pick the 2 or 3 things to focus on that day of the 100+ things vying for your attention.)

And I found this old quote by the mathematician Gronthendieck on Michael Nielson's blog.

In those critical years I learned how to be alone. [But even] this formulation doesn't really capture my meaning. I didn't, in any literal sense, learn to be alone, for the simple reason that this knowledge had never been unlearned during my childhood. It is a basic capacity in all of us from the day of our birth. However these three years of work in isolation [1945-1948], when I was thrown onto my own resources, following guidelines which I myself had spontaneously invented, instilled in me a strong degree of confidence, unassuming yet enduring in my ability to do mathematics, which owes nothing to any consensus or to the fashions which pass as law. By this I mean to say: to reach out in my own way to the things I wished to learn, rather than relying on the notions of the consensus, overt or tacit, coming from a more or less extended clan of which I found myself a member, or which for any other reason laid claim to be taken as an authority. This silent consensus had informed me both at the lycee and at the university, that one shouldn't bother worrying about what was really meant when using a term like "volume" which was "obviously self-evident", "generally known," "in problematic" etc... it is in this gesture of "going beyond" to be in oneself rather than the pawn of a consensus, the refusal to stay within a rigid circle that others have drawn around one -- it is in this solitary act that one finds true creativity. All others things follow as a matter of course.

Since then I’ve had the chance in the world of mathematics that bid me welcome, to meet quite a number of people, both among my "elders" and among young people in my general age group who were more brilliant, much more ‘gifted’ than I was. I admired the facility with which they picked up, as if at play, new ideas, juggling them as if familiar with them from the cradle -- while for myself I felt clumsy, even oafish, wandering painfully up an arduous track, like a dumb ox faced with an amorphous mountain of things I had to learn (so I was assured) things I felt incapable of understanding the essentials or following through to the end. Indeed, there was little about me that identified the kind of bright student who wins at prestigious competitions or assimilates almost by sleight of hand, the most forbidding subjects.

In fact, most of these comrades who I gauged to be more brilliant than I have gone on to become distinguished mathematicians. Still from the perspective of thirty or thirty five years, I can state that their imprint upon the mathematics of our time has not been very profound. They've done all things, often beautiful things in a context that was already set out before them, which they had no inclination to disturb. Without being aware of it, they've remained prisoners of those invisible and despotic circles which delimit the universe of a certain milieu in a given era. To have broken these bounds they would have to rediscover in themselves that capability which was their birthright, as it was mine: The capacity to be alone.

Overall, it made me update that MIRI's decision to be closed-by-default is quite sensible. This section seems trivially correct from this point of view.

Focus seems unusually useful for this kind of work

There may be some additional speed-up effects from helping free up researchers’ attention, though we don’t consider this a major consideration on its own.

Historically, early-stage scientific work has often been done by people who were solitary or geographically isolated, perhaps because this makes it easier to slowly develop a new way to factor the phenomenon, instead of repeatedly translating ideas into the current language others are using. It’s difficult to describe how much mental space and effort turns out to be taken up with thoughts of how your research will look to other people staring at you, until you try going into a closed room for an extended period of time with a promise to yourself that all the conversation within it really won’t be shared at all anytime soon.

Once we realized this was going on, we realized that in retrospect, we may have been ignoring common practice, in a way. Many startup founders have reported finding stealth mode, and funding that isn’t from VC outsiders, tremendously useful for focus. For this reason, we’ve also recently been encouraging researchers at MIRI to worry less about appealing to a wide audience when doing public-facing work. We want researchers to focus mainly on whatever research directions they find most compelling, make exposition and distillation a secondary priority, and not worry about optimizing ideas for persuasiveness or for being easier to defend.

Edited: Added a key section at the end.

Another interesting idea for discussion, is the value of making a long-term commitment to keeping research within a contained environment (i.e. what the OP calls 'nondisclosed-by-default').

There's a bunch of args. Many seem straightforward to me (early research doesn't translate well into papers at all, it might accidentally turn out to move capabilities forward and you want to see it develop a while to be sure it won't, etc) but this one surprised me more, and I'd be interested to know if it resonates/is-dissonant with others' experiences.

We need our researchers to not have walls within their own heads

We take our research seriously at MIRI. This means that, for many of us, we know in the back of our minds that deconfusion-style research could sometimes (often in an unpredictable fashion) open up pathways that can lead to capabilities insights in the manner discussed above. As a consequence, many MIRI researchers flinch away from having insights when they haven’t spent a lot of time thinking about the potential capabilities implications of those insights down the line—and they usually haven’t spent that time, because it requires a bunch of cognitive overhead. This effect has been evidenced in reports from researchers, myself included, and we’ve empirically observed that when we set up “closed” research retreats or research rooms,13 researchers report that they can think more freely, that their brainstorming sessions extend further and wider, and so on.

This sort of inhibition seems quite bad for research progress. It is not a small area that our researchers were (un- or semi-consciously) holding back from; it’s a reasonably wide swath that may well include most of the deep ideas or insights we’re looking for.

At the same time, this kind of caution is an unavoidable consequence of doing deconfusion research in public, since it’s very hard to know what ideas may follow five or ten years after a given insight. AI alignment work and AI capabilities work are close enough neighbors that many insights in the vicinity of AI alignment are “potentially capabilities-relevant until proven harmless,” both for reasons discussed above and from the perspective of the conservative security mindset we try to encourage around here.

In short, if we request that our brains come up with alignment ideas that are fine to share with everybody—and this is what we’re implicitly doing when we think of ourselves as “researching publicly”—then we’re requesting that our brains cut off the massive portion of the search space that is only probably safe.

If our goal is to make research progress as quickly as possible, in hopes of having concepts coherent enough to allow rigorous safety engineering by the time AGI arrives, then it seems worth finding ways to allow our researchers to think without constraints, even when those ways are somewhat expensive.
