I certainly think there are individuals within our species whose cognitive algorithms are performing near-optimally.  I just also have very good reason to think I can develop some algorithms that are better for certain tasks than the ones I consist in: I think there&#x27;s sometimes more information in our sensory data than we take advantage of, and I think that better algorithms could tie together sensing and decision-making to <i>obtain</i> better data more often.  Our brains &quot;bite the Bayesian bullet&quot; a bit too hard, <i>accepting</i> noisy data as-is and just making whatever inferences are feasible, rather than computing how to obtain clearer, less-noisy data (which is why we developed science as a form of domain knowledge rather than as an intuitive algorithm).
