I'm basing my comments about IQ on repeatedly replicated cross national assessment data across all nations involving results of tests of performance on tests of problem solving ability, verbal comprehension, general knowledge, mechanical reasoning etc etc etc. Canadians far outperform Americans. The US ranks above the Czech Republic but below Cambodia and far below Canada.
