Samoderzhaviye is generally unusable. Just the idea of removing all your Governors during a Dark Age sounds terrible to most, regardless of what the card actually does. It may be somewhat helpful if you try to focus all your Production into one central city, which is likely to be the case when you're going for a Scientific Victory, but since it's only available until the Modern Era and prevents you from establishing Magnus to make use of Vertical Integration, it's liable to do more harm than good. You have to be far ahead in terms of Science, which will result in a victory anyway, and in that case this card allows you to win a bit faster, but by no means is it an important, game-changing policy.
Samoderzhaviye – autocracy – was one of the key pillars of Tsarist Russian conservative thought. Whereas other powers experimented with having power spread out between advisors or popular rule, under the philosophy of samoderzhaviye, what the tsar said went. And if the tsar was lazy, incompetent, or ill-informed, this was a liability.
