It really comes down to this...russians are taken from the wild (since the majority of russians sold are wild caught) and undergo the stresses we all know about and despise in crates and overseas trips.
They are typically kept out of hibernation for a year or two to make sure they are healthy.
As we also know, the majority of wild russians die.
So there are two possibilities to think about when keeping a russian from hibernating:
1) The *wild* russian, since its been hibernating all its life, DOES need to hibernate to either feel at ease and gets seriously stressed if it doesnt.
I personally don't feel they have a biological need, just a mental one.
2) The wild russian is stressed to the point of sickness anyway and after a while the symptoms show. This *leads* people to believe they did something wrong and the fact they didn't hibernate is staring them in the face.
So either the idea is perpetuated by the death of stressed torts, or theres a mental need of some sort rather than a biological one.
Would the results be different if we looked at captive bred russians? Shrug. Who'd want to take the chance and do mass testing on their little buddies?
