This is a timeline of decision theory, with a focus on updateless/timeless/acausal decision theories.

Year Month and date Event type Details
1969 Newcomb's problem is discussed by Robert Nozick.
1980 Brian Skyrms's Causal Necessity: A Pragmatic Investigation of the Necessity of Laws discusses the smoking lesion problem (or a similar problem that becomes called the smoking lesion problem in later publications).[1]:128–130 Yudkowsky and Soares cite Skyrms for the smoking lesion problem.[2]:3
1985 The idea of superrationality is introduced by Douglas Hofstadter in his Metamagical Themas.
1997 The Sleeping Beauty problem is first formally analyzed.
1997 The absent-minded driver problem is introduced (in the same paper as the sleeping beauty?).[3][4]
2002 July 17 Hal Finney, in a mailing list discussion, brings up ideas that according to Wei Dai come "pretty close to some of the ideas behind TDT".[5][6]
2006 March 29 On the Theory of Everything Mailing List (everything-list), Wei Dai sends an email with subject "proper behavior for a mathematical substructure". He would later call this "a 2006 proto-UDT".[7]
2006 May 5 Gary Drescher's Good and Real is published.[8]
2007 The Smoking Lesion problem is introduced by Andy Egan?[9][10]
2007 May 30 Philosopher Kenny Easwaran blogs about his discussions with Joshua Von Korff. Korff has apparently devised a decision-theoretic protocol that one-boxes on Newcomb's problem but smokes in the Smoking Lesion problem. The post does not make clear when Korff came up with his ideas or whether he wrote them up anywhere.[11][12]
2009 February Eliezer Yudkowsky starts LessWrong using as seed material his posts on Overcoming Bias.[13] During the following years LessWrong would become the locus of discussion about timeless/updateless decision theory.
2009 March 19 Vladimir Nesov introduces counterfactual mugging.[14][15]
2009 August 13 Wei Dai publishes the post "Towards a New Decision Theory" on LessWrong. The post does not use the term "updateless decision theory" (UDT), but describes what would later be known as UDT.[16][7]
2009 August 20 Gary Drescher proposes Metacircular Decision Theory (MCDT) in a comment on LessWrong.[17]
2010 Timeless decision theory is published in paper form by Eliezer Yudkowsky.[18]
2014 November 4 Project The Intelligent Agent Foundations Forum, run by MIRI, is launched.[19]
2017 March 18 "Cheating Death in Damascus" by Nate Soares and Ben Levinstein is announced on the Machine Intelligence Research Institute blog.[20][21]
2017 October 13 "Functional Decision Theory: A New Theory of Instrumental Rationality" by Eliezer Yudkowsky and Nate Soares is posted to the arXiv.[2] The paper is announced on the Machine Intelligence Research Institute blog on October 22.[22]

  1. Skyrms, Brian (1980). Causal Necessity: A Pragmatic Investigation of the Necessity of Laws. Yale University Press. Suppose that the connection between hardening of the arteries and cholesterol intake turned out to be like this: hardening of the arteries is not caused by cholesterol intake like the clogging of a water pipe; rather it is caused by a lesion in the artery wall. In an advanced state these lesions will catch cholesterol from the blood, a fact which has deceived previous researchers about the causal picture. Moreover, imagine that once someone develops the lesion he tends to increase his cholesterol intake. We do not know what mechanism accounts for this effect of the lesion. We do, however, know that the increased cholesterol intake is beneficial; it somehow slows the development of the lesion. Cholesterol intake among those who do not have the lesion appears to have no effect on vascular health. Given this (partly) fanciful account of the etiology of atherosclerosis, what would a rational man who believed the account do when made an offer of Eggs Benedict for breakfast? I say he would accept. He would be a fool to try to "make it the case that he had not developed the lesion" by curtailing his cholesterol intake. […] Examples could be multiplied. R. A. Fisher once suggested that the correlation between smoking and lung cancer might be due to them both being effects of a common genetic cause. Fisher's hypothesis has not fared well, but if, contrary to evidence, it were true and you knew it to be true, and smoking were consistently pleasurable and not harmful in other ways, you would be foolish to refrain from smoking in order to lower the probability of having smoking-cancer gene. You either have it or not, and you can't influence your genetic makeup by abstinence.
