Yes, but at the same time that’s mathematical statistics. You still have to contend with countless types of biases that skew results in plenty of ways.

Where did they get these people from? The Donbas or Kiev? I’m sure they would have different answers. What ages are the participants? What are their previous political affiliations? Why did they remain in the country when millions of other fled?

Not to mention the biases of the information taker, as those can be nefariously purposeful, or also accidental.

Getting statistics to be as clean as they are in the math will always be next to impossible.
