Greek people are very smart. I dont know about the average, but I know this. Today, in every IT, science, astrophysics, medicine, research renown center, there are many Greeks working.
Different measuring methods give different results and it is a matter of interpretation for each one. Besides, those results are the average and not the rule.
As a rule the common Greek is far smarter than both the Americans and the English.
92 according to this list. Six points behind the US, and eight behind the UK.
