Stone Tools in Europe Were Misinterpreted

For hundreds of years Europeans appear to have been oblivious to the existence of stone tools. Presumably many people saw them. At least it is hard for me to believe that no stone axes, spear points, or arrowheads turned up in plowed fields, dried streambeds, or eroded hillsides. But, as William Stiebing observes, there is no mention of them prior to the 16th century. People apparently “did not notice them. To them such things were just so many more rocks.”3 Writings from the 16th century...

 Plasticity and Lock-In/Entrenchment of Values

Entrenchment of values creates multiple equilibria because there is a significant element of chance in which value system becomes most powerful at a particular place and time, and because, once a value system has become sufficiently powerful, it can stay that way by suppressing the competition. Moreover, the theory of cultural evolution helps to explain why the predominant cultures in society tend to entrench themselves. Simply: those cultures that do not entrench themselves in this way are, ...

 Different Measure of Intelligence Peak at Different Ages

One potential concern with cross-sectional data is that it may be subject to cohort effects. Our findings in Experiment 2 are consistent with the possibility that people born in 1945 have unusually large vocabularies, people born in 1980 have unusually good working memory, and people born in 1990 have unusually fast processing speed. Such concerns can be mitigated by converging results from cross-sectional datasets collected at different times (Schaie, 2005). Here, we compared results derived...

 Close Reading: Emily Dickinson

Tell all the Truth but tell it slant— Success in Circuit lies Too bright for our infirm Delight The Truth's superb surprise As Lightning to the Children eased With explanation kind The Truth must dazzle gradually Or every man be blind— When we first discussed this text with the two teachers who were leading the project, Nealie Bourdon and Becky Campbell, they questioned our choice because they felt that the poem was too difficult for their students. We argued that we wanted to challeng...

 Chomsky on the Failure of Postmodernism to Simplify

Since no one has succeeded in showing me what I'm missing, we're left with the second option: I'm just incapable of understanding. I'm certainly willing to grant that it may be true, though I'm afraid I'll have to remain suspicious, for what seem good reasons. There are lots of things I don't understand -- say, the latest debates over whether neutrinos have mass or the way that Fermat's last theorem was (apparently) proven recently. But from 50 years in this game, I have learned two things: (...
