Final answer:
AKPsi might have international chapters, but it is unrelated to the APS and thus cannot be answered definitively with the provided information. Voting rates in the United States are generally lower than in countries like Sweden and South Korea.
Step-by-step explanation:
The question relates to Alpha Kappa Psi (AKPsi), which is a professional business fraternity. AKPsi has chapters not only in the United States but across the globe. However, the provided reference information pertains to the Association for Psychological Science (APS) and various psychological associations which are distinct and unrelated to AKPsi. It appears there might be a misunderstanding in the question as it does not correlate with the reference information about the APS. Therefore, without specific information about AKPsi, it is not possible to definitively answer whether AKPsi has international chapters in exactly four countries as mentioned in the question.
Regarding the second statement about voting rates, it is false that voting rates are higher in the United States compared to most other democratic industrialized countries like Sweden and South Korea. The US typically has lower voter turnout compared to many other democracies.
