  We show that anthropic selection emerges inevitably in the general framework
for prediction in quantum cosmology. There the predictions of anthropic
reasoning depend on the prior implied by the universe's quantum state. To
illustrate this we compute the probabilities specified by the no-boundary wave
function for our observations at the present time of the values of Lambda and Q
in an inflationary landscape model in which both quantities vary. Within the
anthropic range of values the no-boundary state yields an approximately flat
distribution on Lambda and strongly favors small values of Q. This restores
Weinberg's successful prediction of Lambda.
