 IQ Gains from Early Childhood Programs Fade

Children enrolled in Head Start or in another enriched preschool program, compared to similar children without such preschool, typically show a gain of about 10 IQ points during the year of the Head Start experience. This IQ gain typically fades and then disappears within the first few years of school, so that by second grade neither IQ nor achievement test scores nor¬ mally reveal any difference in performance between those children who had been in Head Start and those who had not been in...

 Redundancy of English language is a Goldilocks zone for C...

In Shannon’s terms, the feature of messages that makes codecracking possible is redundancy. A historian of cryptography, David Kahn, explained it like this: “Roughly, redundancy means that more symbols are transmitted in a message than are actually needed to bear the information.” Information resolves our uncertainty; redundancy is every part of a message that tells us nothing new. Whenever we can guess what comes next, we’re in the presence of redundancy. Letters can be redundant: be...

 Prolongation of Human Infancy

Prolongation of Human Infancy.—-Nevertheless, as Professor Butler has recently pointed out, the doctrine of the prolongation of human infancy, which Professor John Fiske has so ably shown to be part of the theory of evolution, was anticipated by Anaximander of Miletus, who flourished about 565 b.c. Professor Butler’s discovery, however, was itself anticipated by Burnet in his Early Greek Philosophy (95, p. 74) by a couple of years. Burnet, after quoting the Theophrastean account of the sp...

 The Progressive Effects of Education

Homo sapiens, “knowing man,” is the species that uses information to resist the rot of entropy and the burdens of evolution. Humans everywhere acquire knowledge about their landscape, its flora and fauna, the tools and weapons that can subdue them, and the networks and norms that entangle them with kin, allies, and enemies. They accumulate and share that knowledge with the use of language, gesture, and face-to-face tutelage. [...] The mind-altering effects of education extend to every s...

 Evolutionary History Through Macro and Micro Observations

Everything in the cosmos has a history. The old dichotomy between the "historical" sciences (like geology, paleontology and evolutionary biology) and the (for want of a better term) "functional" sciences (like physics and chemistry—some would call them the "real sciences") was always supposed to be that fields like physics study dynamic processes and discover immutable laws of interaction among particles composing the cosmos—while the historical sciences study, well, history—the suppose...

 Understanding the Education Customer

VCs and entrepreneurs tend to be well educated. Well educated people think about education as an investment. You put as many of your resources in to an investment as you can. It may take 20 years to pay off, but if the return-on-investment is high (which it is for education) then you invest. This group of people — if you’re reading this, you fall into this group — generally understand that education is an investment, and as a result are price insensitive and will optimize for quality ...
