It wouldn’t maintain a balance. But that would not be it backfiring. That would be as intended.
It’s like what happened in The Handmaids Tale.
Just remember I’m an Aunt.
The truth is that, when given information about anything, the human brain will make its own decisions about what to do with that information, regardless of the affective context in which the information is presented. The brain makes choices to its own advantage by default. This is why the D.A.R.E. program and sex education failed. Most adolescents make choices on what earns them acceptance in their peer group, so the adolescents who went through those programs just used the information from those programs to better achieve their objective, with disastrous results.
So there is no “backfiring”. Political information is political information, and students will make their own decisions about what to do with that information regardless of how it is presented. More young people are liberals by default, so that skews the data. One can graduate from a liberal university, but if they go work in construction, they will quickly figure out that it is in their best interest to vote Republican, and they will, actually, vote that way.
And yes, I know, I’m an English major and we waste a ton of time editing presentations of information. But that’s all pretty art that doesn’t really influence decision making. People make decisions based on what is in their best interest and the interest of the people they love and care about. If you lie or skew the presentation of the information, that doesn’t work to fool people anymore. This is the golden age of the internet expose, and you’ll get found out, shamed, “canceled”, lawsuited, and lose all your money.
