E. T. Jaynes used to say that you must always use all the information available to you—he was a Bayesian probability theorist, and had to clean up the paradoxes other people generated when they used different information at different points in their calculations. The principle of “Always put forth your true best effort” has at least as much appeal as “Never do anything that might look circular.” After all, the alternative to putting forth your best effort is presumably doing less than your best.
