WHEN: 07 October 2014 06:00:00PM (+0800)

WHERE: Sync Labs, 6/663 Newcastle Street, Leederville, Australia

Come play Zendo, an inductive logic game. Rowdy will teach us, and I'm told the rules are pretty simple.

Zendo seems cool because it can perhaps teach the skill of "looking into the dark".

We'll be at Sync Labs, a coworking space in Leederville. The entrance is between Niche and Cranked. Don't trust Google Maps!

What kind of easy exercises can we do every day to become a little bit more rational? How can we tell if they're working?

WHEN: 29 September 2014 06:00:00PM (+0200)

WHERE: Bistro The Peach, Mariánska 3, Bratislava

Pre tých, čo chvíľu nechodili: Bistro the Peach sa asi pred dvoma mesiacmi presunulo o ulicu ďalej, a možno stále nie je poriadne označené, ale je to oproti predajni richmanov na Mariánskej. Alebo sa riaďte podľa google mapy a čísla ulice. Vchod vyzerá tak, že na začiatku pasáže sú krátke schody do prvej časti bistra, vedľa je druhá časť, kde sedíme, a potom je ešte terasa.

Máme aj mailovú skupinu, kde zvyčajne posielam informácie o ďalších stretávkach. Ale do konca roka 2014 to bude pravidelne, každé 3 týždne.

Causal decision theory is unsatisfactory

13 So8res 13 September 2014 05:05PM

This is crossposted from my new blog. I was planning to write a short post explaining how Newcomblike problems are the norm and why any sufficiently powerful intelligence built to use causal decision theory would self-modify to stop using causal decision theory in short order. Turns out it's not such a short topic, and it's turning into a short intro to decision theory.

I've been motivating MIRI's technical agenda (decision theory and otherwise) to outsiders quite frequently recently, and I received a few comments of the form "Oh cool, I've seen lots of decision theory type stuff on LessWrong, but I hadn't understood the connection." While the intended audience of my blog is wider than the readerbase of LW (and thus, the tone might seem off and the content a bit basic), I've updated towards these posts being useful here. I also hope that some of you will correct my mistakes!

This sequence will probably run for four or five posts, during which I'll motivate the use of decision theory, the problems with the modern standard of decision theory (CDT), and some of the reasons why these problems are an FAI concern.

I'll be giving a talk on the material from this sequence at Purdue next week.

Choice is a crucial component of reasoning. Given a set of available actions, which action do you take? Do you go out to the movies or stay in with a book? Do you capture the bishop or fork the king? Somehow, we must reason about our options and choose the best one.

Of course, we humans don't consciously weigh all of our actions. Many of our choices are made subconsciously. (Which letter will I type next? When will I get a drink of water?) Yet even if the choices are made by subconscious heuristics, they must be made somehow.

In practice, decisions are often made on autopilot. We don't weigh every available alternative when it's time to prepare for work in the morning, we just pattern-match the situation and carry out some routine. This is a shortcut that saves time and cognitive energy. Yet, no matter how much we stick to routines, we still spend some of our time making hard choices, weighing alternatives, and predicting which available action will serve us best.

The study of how to make these sorts of decisions is known as Decision Theory. This field of research is closely intertwined with Economics, Philosophy, Mathematics, and (of course) Game Theory. It will be the subject of today's post.

WHEN: 14 September 2014 03:00:00PM (-0400)

WHERE: U.S. Navy Memorial

Weather permitting, we will meet at the Navy Memorial (south on 8th St from the Portrait Gallery, between D St and Pennsylvania Ave) to practice basic parkour techniques.

If the weather seems to be unsuited to an outdoors meetup, we will meet at the Kogod Courtyard of the National Portrait Gallery (8th and F Sts or 8th and G Sts NW, go straight past the information desk from either entrance) to discuss to-do lists, task management, prioritization, and related topics.

In either case, we plan to congregate between 3:00 and 3:30 p.m. to begin the meeting proper at 3:30.
