Evolutionary religion finds the ends, science and politics the means

An occasional scientist-politician wouldn't hurt rather than so many lawyers, but politicians can mainly use scientists and scientific institutions for research into sociobiology and social psychology, which have substantial knowledge that has been overlooked or buried by politicians, mainly due to political correctness or cultural Marxism. In democracies the people vote on ends which scientists and politicians can find the best means to attain. This also adds meritocracy and slows demagoguery in democracies.

Sociobiological research can help save the population from decline or even disaster. For example, IQ studies have found the law of regression to the mean of the group. A parent with an IQ of 110 will tend to have a child with the IQ of 105 if they are living in a group with a mean of 100. This sort of thing needs to be taken into account with the immigration of large groups of people with lower IQ's than the inhabitants of a country, which eventually has a big effect on the culture and leadership. As the people change the culture changes.  Examine the facts and motives of those who deny this.

However, alone, the science of sociobiology is not enough, it can find the means to the ends that evolutionary religion and politics decide upon. Evolving to Godhood in the cosmos is the primary end goal of life which religion and culture can affirm, as we move, hopefully, to the next level of civilization.
