Genetics
-
Everything Is Heritable:
-
“Why We’re Different: A Conversation with Robert Plomin” (Plomin takes a victory lap: “It might be hard for people to believe this, but forty years ago it was dangerous to talk about genetic influence in psychology.”)
-
“Demonstrating the validity of twin research in criminology”, et al 2014
-
“Pleiotropy across academic subjects at the end of compulsory education”, et al 2015; “Genetics affects choice of academic subjects as well as achievement”, et al 2016
-
“The Genetic Basis of Mendelian Phenotypes: Discoveries, Challenges, and Opportunities”, et al 2015 (But enough about common variants & complex traits—how have we been doing in finding the causes of genetic diseases like severe Mendelian diseases? Well.)
-
“A Prospective Study of Sudden Cardiac Death among Children and Young Adults”, et al 2016 (Rare genetic mutations implicated in >13% of unexplained cardiac deaths. Makes one wonder how much of the long tail of deaths are due to rare variants, and how much of a benefit there would be to erasing the ~80k mutations everyone carries… ( Population genetics rule: rare variants are more harmful than common variants; and 1 harmful mutation, 1 reproductive death to purge it from the population.) Cool application of genetics.)

genetics of breast size:

Recent Evolution:
-
“Assortative mating and differential fertility by phenotype and genotype across the 20th century”, et al 2016 (Dysgenics found in the USA, 1920–1955: the phenotypic correlation of education/intelligence with fertility is also a genetic one—hence, selection against intelligence. Appendix)

Engineering:
-
“The Genome Project-Write”, et al 2016 ( media)
-
Politics/religion
-
“Wealth, Health, and Child Development: Evidence from Administrative Data on Swedish Lottery Players”, et al 2016
-
“Okhrana: The Paris Operations of the Russian Imperial Police” (The back and forth secret war of the Okhrana with the myriads of Russian revolutionaries across Europe, documented by the complete archives of the Paris Okhrana office smuggled to America after the Russian Revolution. When you see how easily and thoroughly the Okhrana had infiltrated the Russian revolutionaries, you start to see why the Communist leadership would be extraordinarily paranoid about spies—but also that the revolutionaries were, well before the Revolution, generally highly nasty folks; many of the mentioned revolutionaries would be summarily executed by their comrades.)
-
“The Unbelievable Tale of Jesus’s Wife”, King’s response; “Bats on the Ceiling: The Gospel of St. Karen” (The Gospel of Jesus’s Wife is a modern forgery. But it gets weirder. And kinkier. Forgeries like this always raise troubling issues about religious scriptures: if this forgery had been kept in private collections for another century before becoming known, in all likelihood, most of the damning evidence would either have disappeared or become inaccessible, and all that would be left is a few worries over the appearance. Most scriptures have even more vexed provenances than does the Gospel of Jesus’s Wife, with blackouts of centuries not uncommon, and known destruction of variants (eg. the well-known destruction of all variants of the Koran). Of course, you might think, who would dare counterfeit the Word of God Himself? Yet, humans are strange and inscrutable and can talk themselves into anything—why did Fritz do it? And why did King go along so easily and unrepentantly? Probably even they don’t really know. Who knows how many Fritzes there have been throughout history…)
AI
-
“Unifying Count-Based Exploration and Intrinsic Motivation”, et al 2016 ( Video; big exploration improvement for DQN-like agents: where DQN can only get to two rooms in Montezuma’s Revenge, because it takes actions mostly at random and it is unlikely that it will randomly do the 15 or 20 exact moves which will get it a reward, this version, with a way of measuring novelty and exploring novel states until a reward is found, can make it to 15 rooms!)
-
“Improved Techniques for Training GANs”, et al 2016 (Even better image generation at 128px now. Synthesizing art can’t be far off.)
-
“InfoGAN: Interpretable Representation Learning by Information Maximizing Generative Adversarial Nets”, et al 2016 (are GANs and VAEs giving us a breakthrough in unsupervised learning?)
-
“Early Visual Concept Learning with Unsupervised Deep Learning”, et al 2016
-
“Progressive Neural Networks”, et al 2016 (NN factored to build different sub-nets for different tasks while allowing later learned tasks to draw on earlier-trained subnets. See also “Actor-Mimic: Deep Multitask and Transfer Reinforcement Learning”, et al 2015.)
-
“Towards an integration of deep learning and neuroscience”, et al 2016
-
“DeepMath—Deep Sequence Models for Premise Selection”, et al 2016
-
“Convolutional Sketch Inversion”, G. et al 2016 (facial sketch → illustration)
-
“Learning to learn by gradient descent by gradient descent”, et al 2016 (Replacing simple SGD, Adadelta, RMSprop etc by a tiny RNN. Probably never practical but still amusing.)
Statistics/meta-Science
-
“Generalized Network Psychometrics: Combining Network and Latent Variable Models”, et al 2016
-
“Statistically Controlling for Confounding Constructs Is Harder than You Think”, 2016 (This is part of why results in sociology/epidemiology/psychology are so unreliable: not only do they usually not control for genetics at all, they don’t even control for the things they think they control for. You have not controlled for SES by throwing in a discretized income variable measured in one year plus a discretized college degree variable. Variables which correlate with or predict some outcome such as poverty, may be doing no more than correcting some measurement error (frequently, due to the heavy genetic loading of most outcomes, correcting the omission of genetic information). This is why within-family designs are desirable even without worries about genetics: they hold constant shared-environment factors so you don’t need to measure or model them. Even a structural equation model (SEM) which explicitly incorporates measurement error may still have enough leakage to render ‘controlling’ misleading. See also 1936/1942/1965.)
Psychology/biology
-
“Ann Roe’s scientists: original published papers” (One of the few data sets, excluding SMPY/TIP, of extremely intelligent people. I am still reading through them but one impression I get is that the education system in America when most of them were growing up around 1910–101920104ya was grossly inadequate & unchallenging; many of them seem to only drift into their field when they happen to run into a challenging course in college. Quite a few mention incredibly little access to books and severe poverty—although interestingly, they all come from what are clearly middle/upper-class descent families, even if in some cases they are so poor as to be unable to afford shoes! Smart kids are so much better off these days with Internet access to anything at all they want to read. As I’ve noted in reading biographies of American scientists, the academic environment pre- and post-WWII is strikingly different than the pressure-cooker race to the bottom we are familiar with now. Relative underperformance in grades compared to females is also a running theme. With the chemists and physicists, home chemistry kits seem to have been nigh universal—which is something that sure doesn’t happen these days.)
-
“Gifted Today But Not Tomorrow? Longitudinal Changes in Ability and Achievement in Elementary School”, 2006 (Challenges in gifted education in elementary or earlier: IQ scores are unstable and so regression to the mean implies that few children that young in G&T programs will grow up to be gifted.)
-
“Is Education Associated With Improvements in General Cognitive Ability, or in Specific Skills?”, et al 2015 (hollowness of IQ gains; see also 2016)
-
“Understanding the Improvement in Disability Free Life Expectancy In the U.S. Elderly Population”, et al 2016 (Adult disability-free life expectancy continues to increase, due in large part to eye surgery improvements; vision is probably, like falling, the proximate cause of a lot of health issues.)
-
“Nicotine Contents in Some Commonly Used Toothpastes and Toothpowders: A Present Scenario”, 2012 (/not sure if harmful or helpful)
-
vision:
-
Orthostatic hypotension: when you stand up and feel like you are about to faint & your vision becomes totally obscured by silver mist
-
Visual snow: when you see the world slightly fuzzy and noisily, like very gentle translucent static on a TV screen
-
Closed-eye hallucination with phospenes: when you close your eyes and see a colored background with blobs and lights, especially in a pitch-black room or at night
-
Technology
-
“Preparing for the Worst: The Space Insurance Market’s Realistic Disaster Scenarios”, et al 2016

Fiction

“Is the Great Attractor a Tengen Toppa Gurren Lagann?”, 2016
