The trouble with judging ideas by their proponents is that there could be confounders. For instance, if intelligent people are more often in white-collar jobs than blue-collar, intelligent people might tend to favor laws benefiting white-collar workers even when they're not objectively correct. Even selecting for benevolence might not be enough--maybe benevolent people tend to go into the government, and people who are benevolent by human standards are still highly ingroup-biased. Then you'd see more benevolent people tending to support more funds and power going to the government, whether or not that's a good idea.
