[WS:] An acquaintance of mine who herself is an India-born scientist expresses similar opinions of her compatriots - but I find that not surprising. Many FOBs are vocally critical of their old countries.
Based on my experience, many Indians whom I met tended to be very good at listening to their interlocutor and then eloquently telling him(her) what they thought he/she wanted to hear, often merely repeating and embellishing what the interlocutor had told them. It is a remarkable social skill to be sure, but it also creates an illusion of extraordinary intellectual capacity.
Of course this is not imply any general characteristics or judgments - just sharing my own experience.
