Ukraine

Propaganda is communication that is primarily used to influence or persuade an audience to further an agenda, which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented.

From Wikipedia. They didn't send the message war is bad for your health like some insurance disclaimer. The selective content tries to induce fear through the incursion into Kursk and for obvious reasons would have never shown the tense situation after the fall of Avdiivka with regular territorial losses in that area. Presentation of dead soldiers is aimed at inducing an emotional response. The intent is and was foremost to demoralize the enemy. I don't think it's reprehensible in any way. Declaring a few cuts as the truth, when you could have shown the opposite with Avdiivka, should tell you that's naive. Call it what is, a Ukrainian military high jacking of Russian TV.

Your example tries to put science into this and the issue we talk about is a war between two countries. Selectively showing information is scientifically inaccurate for history and social science. Science is a way of course to find the truth in a way, but a process of better descriptions of reality.
