The "Bengalis are more intelligent" theory being bandied about by some people here is very amusing. I don't know much about Bangladeshis, but as far as India is concerned, West Bengal is the only state to consistently vote
in the communists to power. Indian communists are notorious for blocking crucial economic reforms for the national economy.(What they do in their state is a diff story) not to mention being more concerned about China's welfare than Indias. Any amount of brains will be insufficient if you keep voting in a govt. which follows archaic and harmful economic policies.
