"Russians seem to value the status quo and are reluctant to change."

Don't agree. If we don't easily accept liberal ideas doesn't mean we are conservative. Look on the history of the XX century and find any sign of conservatism in what happend in Russia.

"Traditional Russian values and core beliefs include: "

I'd call it "list of what differs russians from the others". Let's see:

love of children - nothing exceptional
respect for the old - nothing exceptional
sense of humour - we love good joke, but who doesn't?
strong people-orientation - it's common for all human beings
importance of friendship - agree
generosity - agree
pride - agree, but "We"-pride is higher in Russia then "I"-pride
patriotism - american patriotism is higher, but russian is different - less words and symbols, more self-sacrifice.
love of literature and arts - agree
nostalgia - agree
self-sacrifice - agree
apathy - being in apathy is a shame in Russia
conservatism - as already said, disagree
aversion to change - yeah, that's why we accepted communism, then rejected communism, then accepted liberalism, then rejected liberalism. That's why we sent first object and first man into space. Because we hate changes.
caution - no way. Cautious nations don't have word "авось" in their's dictionary
collectivism - agree
pessimism - no, we are very optimistic (see "авось" )
cynicism - no. It's some modern thing and I believe it's temporary. Just reaction for the dramatic changes of recent 20 years.

I would add: love to science and scient-fiction. Ray Bradbury is, I believe, among 3 most popular american writers in Russia.
