Oh yes, yes! Totally agree!
In my comment I've been referring to a typical russian mentality. And Russian Jews have a very different mentality, from the one I've been referring to.
Typical Russian mentality is thorough approach to problem solving and having a good rest afterwards. Russian language itself structurally teaches your brain to be more abstract.
Nope, but thank you for the reference. My observation comes from the wild, and is confirmed by observations of fellow Russian programmers and sysadmins who lived and worked in the US and the UK.
Actually I'd better refer to Bekhtereva and Stalin, who observed quite the same thing from very different perspectives.
