[1804.04268] Incomplete Contracting and AI Alignment
We suggest that the analysis of incomplete contracting developed by law and economics researchers can provide a useful framework for understanding the AI alignment problem and help to generate a systematic approach to finding solutions. We first provide an overview of the incomplete contracting literature and explore parallels between this work and the problem of AI alignment. As we emphasize, misalignment between principal and agent is a core focus of economic analysis. We highlight some technical results from the economics literature on incomplete contracts that may provide insights for AI alignment researchers. Our core contribution, however, is to bring to bear an insight that economists have been urged to absorb from legal scholars and other behavioral scientists: the fact that human contracting is supported by substantial amounts of external structure, such as generally available institutions (culture, law) that can supply implied terms to fill the gaps in incomplete contracts. We propose a research agenda for AI alignment work that focuses on the problem of how to build AI that can replicate the human cognitive processes that connect individual incomplete contracts with this supporting external structure.

[1509.02504] Electric charge in hyperbolic motion: The early history and other geometrical aspects
We revisit the early work of Minkowski and Sommerfeld concerning hyperbolic motion, and we describe some geometrical aspects of the electrodynamic interaction. We discuss the advantages of a time symmetric formulation in which the material points are replaced by infinitesimal length elements.

We find that supporters of the major parties (Labour, the Conservatives and the Liberal Democrats) have substantively different personality traits. Moreover, we show that those not identifying with any party, who are close to holding the majority, are similar to those identifying with the Conservatives. We show that these results are robust to controlling for cognitive skills and parental party preferences, and to estimation on a subsample of siblings. The relationship between personality traits and party identification is stable across birth cohorts.

Table 2: Big Five Personality Traits: Predictions.
Figure 3: Relationship between personality traits and stable party identification

Conservative core supporters are antagonistic towards others (low Agreeableness), they are closed to new experiences (low Openness), they are energetic and enthusiastic (high Extraversion), they are goal-orientated (high Conscientiousness), and they are even-tempered (low Neuroticism).

In contrast, the core supporters of the Labour Party have a pro-social and communal attitude (high Agreeableness), they are open to new experiences and ideas (high Openness), but they are more anxious, tense and discontented (high Neuroticism) and less prone to goal-directed behavior (low Conscientiousness). The core supporters of the Liberal Democrats have similar traits to the typical Labour supporters with two exceptions. First, they do not show any particular tendency towards pro-social and communal attitudes (insignificant Agreeableness). Second, they are more reserved and introverted than the more extraverted supporters of either the Conservatives or Labour (low Extraversion).

Psychological and Personality Profiles of Political Extremists:
We revisit the debate over the appeal of extremism in the U.S. context by comparing publicly available Twitter messages written by over 355,000 political extremist followers with messages written by non-extremist U.S. users. Analysis of text-based psychological indicators supports the moral foundation theory which identifies emotion as a critical factor in determining political orientation of individuals. Extremist followers also differ from others in four of the Big Five personality traits.

Fig. 2. Comparing psychological profiles of the followers of moderate and extremist single-issue groups, compared to random users.

Overall, the differences in psychological profile between followers of extremist and moderate groups is much larger for left-wing extremists (environmentalists) than right-wing (anti-abortion and anti-immigrant).

Fig. 3. Big Five Personality Profiles.

Results show that extremist followers (whether left or right) are less agreeable, less neurotic, and more open than nonextremists.

Ideology as Motivated Cultural Cognition: How Culture Translates Personality into Policy Preferences:
This paper summarises the results of a quantitative analysis testing the theory that culture acts as an intermediary in the relationship between individual perceptual tendencies and political orientation. Political psychologists have long observed that more “left-wing” individuals tend to be more comfortable than “right-wing” individuals with ambiguity, disorder, and uncertainty, to equivocate more readily between conflicting viewpoints, and to be more willing to change their opinions. These traits are often summarised under the blanket term of “open-mindedness”. A recent increase in cross-cultural studies, however, has indicated that these relationships are far less robust, and even reversed, in social contexts outside of North America and Western Europe. The sociological concept of culture may provide an answer to this inconsistency: emergent idea-networks, irreducible to individuals, which nonetheless condition psychological motivations, so that perceptual factors resulting in left-wing preferences in one culture may result in opposing preferences in another. The key is that open-mindedness leads individuals to attack the dominant ideas which they encounter: if prevailing orthodoxies happen to be left-wing, then open minded individuals may become right-wing in protest. Using conditional process analysis of the British Election Study, I find evidence for three specific mechanisms whereby culture interferes with perceptual influences on politics. Conformity to the locally dominant culture mediates these influences, in the sense that open-minded people in Britain are only more left-wing because they are less culturally conformal. This relationship is itself moderated both by cultural group membership and by Philip Converse’s notion of “constraint”, individual-level connectivity between ideas, such that the strength of perceptual influence differs significantly between cultural groups and between levels of constraint to the idea of the political spectrum. Overall, I find compelling evidence for the importance of culture in shaping perceptions of policy choices.

Stability of the Solar System - Wikipedia
The stability of the Solar System is a subject of much inquiry in astronomy. Though the planets have been stable when historically observed, and will be in the short term, their weak gravitational effects on one another can add up in unpredictable ways. For this reason (among others) the Solar System is chaotic,[1] and even the most precise long-term models for the orbital motion of the Solar System are not valid over more than a few tens of millions of years.[2]

The Solar System is stable in human terms, and far beyond, given that it is unlikely any of the planets will collide with each other or be ejected from the system in the next few billion years,[3] and the Earth's orbit will be relatively stable.[4]

Since Newton's law of gravitation (1687), mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, Vladimir Arnold and Jürgen Moser) have searched for evidence for the stability of the planetary motions, and this quest led to many mathematical developments, and several successive 'proofs' of stability of the Solar System.[5]


The planets' orbits are chaotic over longer timescales, such that the whole Solar System possesses a Lyapunov time in the range of 2–230 million years.[3] In all cases this means that the position of a planet along its orbit ultimately becomes impossible to predict with any certainty (so, for example, the timing of winter and summer become uncertain), but in some cases the orbits themselves may change dramatically. Such chaos manifests most strongly as changes in eccentricity, with some planets' orbits becoming significantly more—or less—elliptical.[7]

[1709.06560] Deep Reinforcement Learning that Matters
I’ve been experimenting w/ various kinds of value function approaches to RL lately, and its striking how primitive and bad things seem to be
At first I thought it was just that my code sucks, but then I played with the OpenAI baselines and nope, it’s the children that are wrong.
And now, what comes across my desk but this fantastic paper: (link: How long until the replication crisis hits AI?
Seriously I’m not blown away by the PhDs’ records over the last 30 years. I bet you’d get better payoff funding eccentrics and amateurs.
There are essentially zero fundamentally new ideas in AI, the papers are all grotesquely hyperparameter tuned, nobody knows why it works.

Deep Reinforcement Learning Doesn't Work Yet:
Once, on Facebook, I made the following claim.

Whenever someone asks me if reinforcement learning can solve their problem, I tell them it can’t. I think this is right at least 70% of the time.

Fermat's Library | Cassini, Rømer and the velocity of light annotated/explained version.
Abstract: The discovery of the finite nature of the velocity of light is usually attributed to Rømer. However, a text at the Paris Observatory confirms the minority opinion according to which Cassini was first to propose the ‘successive motion’ of light, while giving a rather correct order of magnitude for the duration of its propagation from the Sun to the Earth. We examine this question, and discuss why, in spite of the criticisms of Halley, Cassini abandoned this hypothesis while leaving Rømer free to publish it.
