I strongly doubt it is related to intellectual ability but cultural expectations. Some years back someone did a study about which country's US diplomats at the UN had the highest number of NYC parking tickets. Diplomats don't need to pay parking fines due to immunity. This is very similar to returning shopping carts. As I recall, it was clearly correlated with country, which in turn was connected to national corruption rates. Ahh, here: https://www.nber.org/system/files/working_papers/w12312/w123... > Overall, the basic pattern accords reasonably well with common perceptions of corruption across countries. The worst parking violators – the ten worst are Kuwait, Egypt, Chad, Sudan, Bulgaria, Mozambique, Albania, Angola, Senegal, and Pakistan – all rank poorly in cross-country corruption rankings. While many of the countries with zero violations accord well with intuition (e.g., the Scandinavian countries, Canada), there are a number of surprises. Some of these are countries with very
small missions (e.g., Burkina Faso and the Central African Republic), and a few others have high rates of parking violations but do pay the fines (these are Bahrain, Malaysia, Oman, and Turkey; we return to this issue below). I've read far too many stories of people who don't clean up after themselves at a store or restaurant, justified by "no need - they pay someone to do this" or even "it's a good thing I do this otherwise you wouldn't have a job" to know it's simply intellectual ability. |
The IQ of a crowd isn't the same as the IQ of the people in it, but it is related.
