It therefore sometimes seems that we make no progress at all; however, when I look back on what we have accomplished over the last half-century in the fields in which I have More

  • The Minimum Description Length Principle

    Both as scientists and in our everyday lives, we make probabilistic inferences. Mathematicians may deduce their conclusions from their stated premises, but the rest of us induce our conclusions from data. As scientists, we do so by examining the extent to which our hypotheses — the conclusions we might draw More

  • Psychological Science and Viewpoint Diversity

    There is broad consensus within the community of researchers in psychological science that ethnic and gender diversity are good for the science. APS works hard, as a matter of policy and conviction, to promote that diversity. The question is whether diversity of political conviction is similarly important, and, if so More
