When good news leads to bad choices

Climate sensitivity uncertainty: when is good news bad?

Climate change is real and dangerous. Exactly how bad it will get, however, is uncertain. Uncertainty is particularly relevant for estimates of one of the key parameters: equilibrium climate sensitivity--how eventual temperatures will react as atmospheric carbon dioxide concentrations double. Despite significant advances in climate science and increased confidence in the accuracy of the range i...

There is much that is attractive about Michael Burawoy’s examination of the critical turn to a public sociology. I find plausible his account of the academic nature of 1970s radical sociology especially that mobilized notions such as Althusser’s “theoretical practice.” I also was cheered to read the account of the positive developments currently in train in the USA and especially with how socia...

Good news is more persuasive when it is more consistent, and bad news is less damaging when it is less consistent. We show when Bayesian updating supports this intuition so that a biased sender prefers more or less variance in the news depending on whether the mean of the news exceeds expectations, and we apply the result to selective news distortion by a manager of multiple projects. If news f...

Yet the Lisp community has failed to do as well as it could have. In this paper I look at the successes, the failures, and what to do next. The Lisp world is in great shape: Ten years ag...
